Last edited: 20 February 2024

This guidance applies to the calculation of PIAWE for workers injured on or after 21 October 2019. For workers injured prior to 21 October 2019, see GN 5.1 Calculating PIAWE for workers injured before 21 October 2019.

This guidance does not apply to exempt workers or coal miners.

Overview

Workers compensation legislation requires the insurer to commence provisional weekly payments of compensation within seven days after initial notification to the insurer of an injury, unless there is a reasonable excuse for not commencing weekly payments.

In order to commence weekly payments of compensation, the insurer must calculate the worker’s pre-injury average weekly earnings (PIAWE). The calculation of the worker’s PIAWE is a work capacity decision under section 43(1)(d) of the Workers Compensation Act 1987 (1987 Act).

Pay information should be requested from the employer as soon as practicable to meet the legislated timeframe for commencing weekly payments - see sections 267 and 275 of the Workplace Injury Management and Workers Compensation Act 1998 (1998 Act).

Insurers may consider taking proactive steps to gather earnings information for a worker who presents with a certificate of capacity with restrictions, but where there is no loss of earnings.

Workers and employers can reach an agreement as to the amount of a worker’s PIAWE- see Schedule 3, clause 3 to the 1987 Act and Division 4, Part 4 of the Workers Compensation Regulation 2016 (2016 Regulation). For the insurer to commence weekly payments within seven days of initial notification, the agreement is to be reached promptly.

Definition of ‘pre-injury average weekly earnings’

PIAWE is the average of a worker’s gross weekly earnings over the 52 weeks prior to their date of injury. There are some exceptions to this definition which are noted below.

Formula which shows Gross earnings divided by Relevant earning period (in weeks) equals PIAWE

If a worker is employed by more than one employer at the date of injury, the earnings for all jobs are considered when determining PIAWE (see Schedule 3, clause 2 of the 1987 Act).

Refer to the PIAWE Reference Guide for an overview of how to calculate PIAWE.

Earnings and income

Earnings is income received by the worker for work performed in any employment during the relevant earning period. This can include wages, shift and other allowances, overtime amounts, commissions, the value of non-monetary benefits (if a worker no longer has the use of the benefit - see section non-monetary benefits below for further details), salary sacrificed superannuation contributions and piece rates.

Schedule 3, clause 6(2) to the 1987 Act outlines what is not considered income for the purposes of calculating PIAWE:

  • compulsory superannuation contributions made by the employer
  • a non-monetary benefit if the worker continues to be entitled to the use of the benefit after the injury
  • compensation for loss of earnings under an insurance or compensation scheme (this includes workers compensation payments made during the relevant earning period), and
  • any discretionary payment made without obligation by the employer (this can include incentive bonus payments).

Allowances

A worker can receive an allowance related to the performance of overtime or shift work (for example, a meal allowance). Other common allowances include allowances for uniforms, tools and equipment, and first aid. However, any allowances which the worker has received or is entitled to receive reimbursement for are not considered as earnings.

Commissions

Workers who receive commission payments are paid based on completion of a task, or by how much they sell. This may or may not be in addition to an hourly rate of pay.

Piece rates

Workers receiving piece rates are paid for each unit of production at a given rate, rather than receiving an hourly rate of pay for their work.

JobKeeper payments

Any additional payment subsidised by the JobKeeper scheme are not considered earnings (that is, any ‘top-up’ component of the JobKeeper scheme payment) for the purposes of calculating PIAWE (see Schedule 3, clause 10 of the 1987 Act). The JobKeeper scheme payments ceased on 31 March 2022.

Non-monetary benefits

Non-monetary or ‘non-cash’ benefits are earned by workers in the place of salary. They can include, for example, education fees, residential accommodation, child care or the use of a motor vehicle.

The 1987 Act and Part 10 of the Workers Compensation Guidelines (Guidelines) state that non-monetary benefits must 'be provided to a worker for the performance of work by the worker' and 'expressly [provide] a personal benefit to the worker'.

A worker is considered to have been provided with a non-monetary benefit if they have use of the non-monetary benefit at the date of injury. The non-monetary benefit may only be included in the worker’s PIAWE from the date that the benefit has been relinquished by the worker or withdrawn by the employer after the injury (see Schedule 3, clause 6(3) of the 1987 Act).

Salary sacrificed items can be considered non-monetary benefits if they are included as part of a salary package. If the value of the item is included in the gross earnings as part of a salary package, the value of the item will need to be separately identified if the non-monetary benefit is retained by the worker. Salary sacrificed superannuation contributions (i.e. the value of any voluntary contribution amounts made from a worker’s pre-tax earnings over and above the minimum amount paid by the employer to meet the employer’s superannuation obligations under federal legislation) forms part of a workers gross earnings for the purposes of calculating PIAWE.

Amending PIAWE to include the value of non-monetary benefits

If a non-monetary benefit is relinquished by the worker, or withdrawn by the employer, after PIAWE has already been determined and applied, the worker’s PIAWE must be amended to include the value of the benefit. The new PIAWE amount is effective from the date the worker is no longer entitled to the non-monetary benefit.

  • If the PIAWE amount had originally been determined by the making of a work capacity decision by the insurer, the insurer is to determine the monetary value of the non-monetary benefit and include this value into PIAWE by making a work capacity decision (under section 43(1)(d) of the 1987 Act). A work capacity decision notice is to be sent to the worker and written advice of the new PIAWE amount is to be provided to the employer.
  • If the original PIAWE amount had been determined by agreement between the worker and the employer, the worker and employer may agree a value for the non-monetary benefit. In this situation the original agreement may be varied to include this value in the worker’s PIAWE, however it is still subject to the insurer's approval. This new agreed PIAWE becomes the new PIAWE, and the worker and the employer are to be advised in writing of the new PIAWE amount.
  • If the original PIAWE amount had been determined by agreement, and the worker and employer cannot agree on the value for the non-monetary benefit, the insurer is to make a work capacity decision regarding PIAWE. A decision notice is to be sent to the worker, and written advice of the new amount is to be provided to the employer. The work capacity decision must include an insurer calculation of PIAWE (rather than simply reflect the amount agreed in the original agreement).

Calculating the value of a non-monetary benefit

There are two ways to calculate the value of a non-monetary benefit, depending whether fringe benefits tax applies (see below).

The value is calculated as an annual amount. This figure is to be divided by 52 weeks to determine a weekly amount. This weekly amount is then multiplied by the number of weeks in the relevant earning period and added into the worker’s gross earnings.

If fringe benefits tax applies

The employer or the Australian Tax Office (ATO) can advise whether fringe benefits tax applies to a non-monetary benefit. The formula provided in Schedule 3, clause 7(2) of the 1987 Act is used to calculate the value of the non-monetary benefit.

Value as a fringe benefit is to be determined in accordance with the formula:

Formula of TV multiplied by 1 divided by 1 minus the FBT rate

TV is the taxable value of the benefit as a fringe benefit under the Fringe Benefits Tax Assessment Act 1986 of the Commonwealth.

FBT rate is the rate of fringe benefits tax imposed by the Fringe Benefits Tax Assessment Act 1986 of the Commonwealth that applies when the non-monetary benefit was provided to the worker.

The taxable value of the benefit can be obtained from the employer. An employer must lodge a Fringe Benefits Tax (FBT) return if they have a liability during an FBT year (between 1 April to 31 March). The FBT rate is available from the ATO website and is the rate applicable when the non-monetary benefit was provided to the worker.

Nandita fractured her left ankle on 21 October 2019 while working as a pharmaceutical salesperson.

When she commenced employment on 7 January 2019, she was provided with a motor vehicle for business and personal use. This was then withdrawn by her employer from 21 October 2019 after she sustained her injury.

The insurer determined the value of the non-monetary benefit using the formula provided in Schedule 3, clause 7(2) of the 1987 Act.

The taxable value (TV) is $5,567.00. The employer had used the operating cost method on the Australian Tax Office (ATO) website to determine the value, and this value was reported by the employer to the ATO during the 2018-19 financial year.

The fringe benefits tax (FBT) rate is 47 per cent. This rate was obtained from the ATO website, and based on the date Nandita was provided with the non-monetary benefit (January 2019).

Calculations using formula under Schedule 3, Clause 7(2) of the 1987 Act.

The value is calculated as an amount per annum based on the employer’s FBT reporting requirements to the ATO for the 2018-19 tax year. To obtain a weekly value for the non-monetary benefit, the annual amount must be divided by 52 weeks.

The monetary value of the motor vehicle is $202.00 per week and this amount was multiplied by the number of weeks in her relevant earning period and added to the cash component of her earnings to determine Nandita’s PIAWE.

If the benefit is exempt from fringe benefits tax

If an item is exempt from fringe benefits tax, the amount reasonably payable for that non-monetary benefit must be used. In most cases, this amount can be obtained from the employer, as the employer is required to keep these records for tax reporting purposes.

Part 10.3 of the Guidelines includes the following factors to be considered when determining the monetary value of a non-monetary benefit:

  • Pay As You Go (PAYG) summaries provided to the worker, or accounting / tax return information for working directors
  • the worker’s contract of employment
  • records kept by the employer as to the value of the non-monetary benefit
  • any records kept by the worker

Insurers may consider other available information where appropriate to do so.

Where this information cannot be obtained from the employer, the insurer will need to determine the amount with reference to other comparable sources. For example, the Rent and Sales Report produced by the NSW Department of Communities and Justice can be used as a guide for the reasonable rental amount that is payable for residential accommodation that is not subject to fringe benefits tax.

(See Schedule 3, clause 7 of the 1987 Act)

Jennifer sustained a dislocated shoulder when she was assaulted at work in December 2019. She has been employed for more than 52 weeks and works for Stay Well, a registered public benevolent and health promotion charity.

As a registered charity, her employer is exempt from paying fringe benefits tax. She has a salary package which includes annual professional membership, education fees and cash earnings. Her cash earnings component is $82,560 per year. The amounts paid by the employer on Jennifer’s behalf for her education fees and professional membership are pre-tax amounts.

The insurer determines the value of the education fees to be $8,250.00 per year and the value of the professional membership to be $750.00 per year, based on the employer records of the after-tax value of these items.

Jennifer’s gross earnings for the 52 weeks are:

$82,560 + $8,250 + $750 = $91,560

Her PIAWE is:

$91,560 ÷ 52 = $1,760.77 per week

Relevant earning period

The relevant earning period is the 52-week period before the worker's date of injury. The relevant earning period may be adjusted in the following situations, and in the following order:

  1. to take into account a period of less than 52 weeks of continuous employment with the pre-injury employer
  2. to take into account any financially material change in the workers earnings circumstances
  3. to align with any regular interval at which the worker is paid (optional)
  4. to take into account periods of unpaid leave
  5. to take into account a financially material reduction in earnings due to the COVID-19 pandemic in the prescribed periods.

Relevant earning period workflow

The relevant earning period workflow describes each of the circumstances during the 52 weeks before a worker’s date of injury which may adjust the relevant earning period.  Pre-injury average weekly earnings are the earnings received by the worker between the start and the end of the relevant earning period, divided by the number of weeks in the relevant earning period. The general rule is that the relevant earning period is the 52 weeks prior to the date of injury. Step one: Was the worker continuously employed with their employer for less than 52 weeks prior to their date of injury? If yes, adjust the period to this lesser period. Step two: Did the worker have a financially material change in earnings during the period? If yes, adjust the period to commence from the date of the change. Step three: Is it simpler to align the period with the workers employment pay cycle? If yes, the period commences from the first pay week start date and ends on the last pay week end date. Step four: Did the worker take any extended periods of unpaid leave (greater than or equal to 7 consecutive days of lost earnings)? If yes, exclude the period from the date of the first day of unpaid leave until the day before the next payable day. The relevant earning period is therefore the number of weeks less any period/s of unpaid leave. Note: increases apply to apprentices, trainees and workers under 21 years of age after their date of injury.

(See Part 4, Division 2 of the 2016 Regulation)

An alternative method exists for workers continuously employed with the pre-injury employer for less than four weeks (refer to the section on ‘short term workers’ below).

Workers not continuously employed

If a worker has been continuously employed with their pre-injury employer for less than 52 weeks, the relevant earning period is adjusted to exclude the period before their first day of employment.

Financially material change to earnings

If there was an ongoing change to the worker’s employment arrangement resulting in a financially material change to the worker’s earnings during the 52 weeks immediately prior to the injury, the relevant earning period is adjusted to exclude the period before the change (see section 8C of the 2016 Regulation).

Examples include an ongoing (not temporary): change in role, change in duties, change in work hours (such as part time to full time), promotion, demotion or other change in earnings circumstances. A worker’s individual circumstances must be considered when determining if the change is financially material.

Bronwyn was employed as a Director in a child care centre. Her full-time earnings were $1,219.00 per week. She injured her wrist after tripping on Lego at the centre, and currently has no capacity for work.

During the 52 weeks before her date of injury, she had been working full time (18 weeks). She had also taken 18 weeks maternity leave at half pay after the birth of her child.

She then returned to work initially for 2 days per week for 8 weeks, and then 3 days per week up until her date of injury (a further 8 weeks). During the 52-week period before her injury Bronwyn took no unpaid leave, performed no overtime or shift work and received no allowances or non-monetary benefits.

The insurer determined that she had a change in earnings circumstances when she increased to 3 days per week on an ongoing basis. Therefore, her PIAWE was calculated based on a relevant earning period of 8 weeks since this change, during which Bronwyn earned $5,851.36.

The insurer determined Bronwyn’s PIAWE to be:

$5,851.36 ÷ 8 = $731.42 per week.

Alignment of relevant earning period with the worker’s pay period

An insurer may choose to align the workers relevant earning period with the employers pay period if it will make the determination of PIAWE more straightforward (see section 8D of the 2016 Regulation).

This approach is not to be used if the insurer considers that, by aligning with the pay period, the result would likely decrease the worker’s PIAWE.

The period may be adjusted in any way (shifted, reduced or extended) but may not be adjusted so that it commences on a day before the day on which a material and ongoing change to the worker’s earnings took effect.

This provision makes it easier for insurers to determine a worker’s earnings during the relevant earning period by enabling insurers to adjust the relevant earning period so that:

  • the relevant earning period commences on day one of the first full pay period in the 52-week period immediately prior to the date of injury, or
  • where there has been a material and ongoing change in the worker’s earnings during the 52 weeks immediately prior to the date of injury, the relevant earning period commences on the first day of the first full pay period after the day on which the change in the worker’s earnings took effect

AND

  • the relevant earning period ends on the last day of the last full pay cycle immediately prior to the date of injury.

Pauline was employed as a medical receptionist for 3 and a half years. She worked 38 hours per week, Monday to Friday. On Friday 8 November 2019 she injured her lower back during the course of her employment. She had taken no unpaid leave, and her earnings circumstances had not changed. Pauline's regular pay cycle was Thursday-Wednesday.

Her relevant earning period was therefore adjusted to disregard the day before her injury (Thursday 7 November 2019) to align with her pay cycle and extended by a corresponding day at the beginning of the period to allow for 52 full weeks. Pauline’s adjusted relevant earning period was the 52 weeks between Thursday 8 November 2018 to Wednesday 6 November 2019.

52 weeks adjusted by 3 days to align with pay cycle

Unpaid leave

The relevant earning period for a worker is to be adjusted if, during any period of seven or more consecutive calendar days within the relevant earning period the worker did not receive earnings and took a period of unpaid leave. That period of unpaid leave is to be excluded from the relevant earning period for the worker. The excluded period is defined from the first day of unpaid leave and ends on the day before the worker returns to work or to a day of paid leave.

Thomas worked 3 days per week (Tuesday, Thursday and Friday). He commenced employment as an executive assistant on 20 August 2019 and sustained a work-related injury on 7 November 2019.

From Thursday 3 October to Friday 18 October 2019 he took 3 weeks leave comprising 3 days paid sick leave and 5 days unpaid leave. He returned to work on 22 October 2019 (see calendar below).

For the purposes of adjusting the relevant earning period, the consecutive period commenced from the first day he took unpaid leave (Thursday 10 October) and ended on the day before he resumed work (Monday 21 October), as highlighted on the calendar below. The period was 12 days (or 1.7 weeks) and therefore was excluded from the relevant earning period as it is greater than 7 consecutive calendar days.

Note, if the period following the unpaid leave period was a day of paid leave (on 22 October), this would be treated the same as above.

Calendar October 2019, highlight days worked Tuesday, Thursday and Friday. Highlighted days sick and unpaid leave day. Outlines unpaid leave period from 10 October to 21 October 2019.

An unpaid maternity leave arrangement may be dealt with in accordance with the unpaid leave provisions, depending on the return to work arrangements after the maternity leave period.

Eva was employed as a laboratory technician. Her full-time earnings were $1,225.10 per week. She also received a laundry allowance of $9.49 per week. Eva injured her arm after a chemical burn, and currently has no capacity for work.

During the 52 weeks before her date of injury, Eva had been working full time however she took 18-weeks of unpaid maternity leave after the birth of her child. Eva then returned to work on a full-time basis. Eva performed no overtime or shift work and received no other allowances or non-monetary benefits during the relevant earning period.

Her relevant earning period was determined by excluding the 18 weeks of unpaid leave. Her gross earnings for the period were $41,976.06 (this includes her weekly laundry allowance), and her relevant earning period was 34 weeks.

Her PIAWE was therefore $41,976.06 ÷ 34 = $1,234.59

The insurer determined Eva’s PIAWE to be $1,234.59 per week.

Financially material reduction in earnings due to COVID-19

Changes made to the calculation of PIAWE impacted by the COVID-19 pandemic apply from 23 October 2020.

Clause 8EA of the 2016 Regulation allows for adjustment to the relevant earning period for workers who have had a change in their employment arrangements due to the impact of the COVID-19 pandemic on their employer. The change must result in a financially material reduction in the worker's earnings. This includes earnings reduced to zero. A reduction in earnings may arise from a worker working fewer hours or accepting a lower rate of pay.

There are two prescribed periods which may be excluded from the relevant earning period:

1. First prescribed period

The first prescribed period is 23 March 2020 to 14 June 2020. The whole period is excluded from the relevant earning period if the worker experienced a material reduction in their earnings over the entire prescribed period.

2. Second prescribed period

The second prescribed period commences on 15 June 2020 and ends on the earlier of:

  • 27 September 2020 or
  • the day before the worker earns in any employment.

The second prescribed period may only be excluded if the worker’s relevant earning period has already been adjusted by the exclusion of the first prescribed period.

If at the end of the first prescribed period, the worker had no earnings for work performed in any employment, the second prescribed period is to be excluded. This means the worker was not performing any work, but may have been receiving the JobKeeper Scheme payment. Note that workers remain continuously employed if they have been temporarily ‘stood down’ during the pandemic but remain employed by the employer.

Charlotte was a full-time worker employed more than 52 weeks before her date of injury. She earned $791.16 per week as a full time worker. Her date of injury was 4 November 2020. On March 23, she was stood down due to the closure of her employer's business because of the pandemic. She received the JobKeeper payment from 23 March 2020, although due to public health orders, she was unable to work. Once restrictions eased in NSW from 15 June 2020, she went back to work, working 15 hours per week. Her earnings for work performed were $312.30 per week. She continued to receive the JobKeeper payment of $750 per week until 27 September 2020.  She received the Tier One JobKeeper payment ($600 per week) from 28 September 2020 until her date of injury.

Relevant earning period

The first prescribed period was excluded from the relevant earning period, as there was a financially material reduction to Charlotte’s earnings from 23 March 2020 until 14 June 2020 (12 weeks). Earnings became payable again on 15 June 2020 when she returned to work, therefore no time within the second prescribed period is to be excluded.

Relevant earning period = 40 weeks (52 – 12)

Gross earnings and the JobKeeper payment

Although Charlotte received the JobKeeper payment from 23 March 2020 until the date of injury, only earnings for work performed are included in the calculation of PIAWE.

Earnings for work performed before 23 March 2020 were $791.16 per week. There were no earnings for work performed from 23 March 2020 – 14 June 2020. Earnings became payable again from 15 June 2020 at $312.30 per week.

$791.16 x 19.7 weeks (6/11/19 – 22/3/20)

The first prescribed period of 23/3/20 – 14/6/20 was excluded.

$312.30 x 20.3 weeks (15/6/20 – 3/11/20)

15,585.85 + 6,339.69

Gross earnings = $21,925.54

PIAWE calculation

$21,925.53 ÷ 40

= $548.14 per week

Ned was a full-time worker employed more than 52 weeks before he was injured at work on 4 November 2020. His weekly earnings before 23 March 2020 were $2,180.06 per week. On 23 March 2020, his hours were halved due to the impact of the pandemic on his employer, and his weekly earnings became $1090.03. The JobKeeper payment made up $750 of this amount until 27 September 2020, and then $375 per week until his date of injury. He had not increased his hours of work since 23 March 2020.

Relevant earning period

The first prescribed period was excluded from the relevant earning period, as there was a financially material reduction to Ned’s earnings from 23 March until 14 June 2020. No time within the second prescribed period was excluded, as Ned received earnings for work performed on and after 15 June 2020.

The relevant earning period is 40 weeks.

Gross earnings and the JobKeeper payment

Although in receipt of the JobKeeper payment from 23 March 2020 until the date of injury, only earnings for work performed are included in the calculation of PIAWE.

Earnings for work performed before March 23 were $2,180.06 per week.  Earnings for work performed after this date until the date of injury were $1090.03 per week.

$2,180.06 x 19.7 weeks (6/11/19 – 22/3/20)

The first prescribed period of 23/3/20 – 14/6/20 was excluded.

$1090.03 x 20.3 weeks (15/6/20 – 3/11/20)

42,947.18 + 22,127.61

Gross earnings = $65,074.79

PIAWE calculation

$65,074.79 ÷ 40

= $1,626.87 per week

Elsie was employed as a full-time worker more than 52 weeks before her date of injury on 4 November 2020. Her weekly earnings before the pandemic were $995.50. Elsie continued working on a full-time basis until Friday 1 May 2020, with the JobKeeper payment making up $750 of her weekly earnings during this time. She was stood down from Monday 4 May 2020 due to the effect of the pandemic on her employer and she returned to work on a part time basis on 17 August 2020, earning $497.75 per week for work performed. Elsie continued to receive the JobKeeper payment until her date of injury.

Relevant earning period

The first prescribed period from 23 March 2020 until 14 June 2020 (12 weeks) was excluded from the relevant earning period. Although Elsie continued working full time after the commencement of the first prescribed period, her earnings during the first prescribed period averaged $497.75 per week, as she ceased working after 1 May 2020.

As Elsie was stood down before the beginning of the second prescribed period, and returned to work on 17 August 2020, the relevant earning period is adjusted to also exclude part of the second prescribed period from 15 June 2020 – 16 August 2020 (the day before earnings were once again payable). This was a period of 9 weeks.

The relevant earning period = 31 weeks (52 – 12 – 9)

Gross earnings and the JobKeeper payment

Although in receipt of the JobKeeper payment from 23 March 2020 until the date of injury, only earnings for work performed are included in the calculation of PIAWE.

Earnings for work performed before the beginning of the first prescribed period were $995.50. There were no earnings for work performed from 4 May 2020 – 16 August 2020. Earnings became payable again from 17 August 2020 at $497.75 per week.

The first prescribed period and part of the second prescribed period are excluded.

$995.50 x 19.7 weeks (6/11/19 – 22/3/20)

$497.95 x 11.3 weeks (17/8/20 – 3/11/20)

19,611.35 + 5,626.84

PIAWE calculation

$25,238.19 ÷ 31

= $814.14 per week

Casual and seasonal workers

Calculating PIAWE for casual or seasonal workers requires careful consideration of the relevant earning period. Casual and seasonal workers may have long periods not working, or they may work for multiple employers during the unadjusted relevant earning period.

Casual workers do not receive paid leave, but their employer can agree for workers to not work for holidays or for other reasons. Gaps in employment may be due to lack of availability of work, or due to worker choice.

The relevant earning period may be adjusted for these workers as it is for all workers.

Vanessa was employed as a casual kitchen hand for 18 months when she injured her left hand while preparing food. She worked to a roster on a week by week basis. Usually she worked two or three shifts a week, but sometimes she worked more or less. In April 2023, she negotiated with her employer to take some time away from work for three full weeks in May to take a holiday. After her holiday, she resumed her week to week shift roster.

Vanessa was also employed as a casual private tutor in her spare time, working around five hours a week. She also ceased this work to go on her holiday.

Vanessa’s earnings as a kitchen hand for the 52 weeks before her injury were $41,358.72.

Her earnings in the tutoring job for the 52 weeks were $7,370.20.

Her gross earnings for the period were $48,728.92 and her relevant earning period was 52 weeks. The period was not adjusted to account for the three weeks of holiday.

Her PIAWE was therefore $48,728.92 ÷ 52 = $937.09.

Sarah was employed as a casual teacher’s aide when she injured her back in the classroom. She had been working five days per week when she sustained her injury in August 2023. From December 2022 until May 2023, she took time away from her job to undertake a training program. When she resumed work in May 2023 her hourly rate of pay had increased from $42.85 per hour to $44.63 per hour. The insurer determined that Sarah had a change in earnings circumstances when she returned to work in May 2023. Therefore, her PIAWE was calculated based on a relevant earning period of 12 weeks from May until August 2023, during which Sarah earned $16,066.80.

The insurer determined Sarah’s PIAWE to be:

$16,066.80 ÷ 12 = $1,338.90 per week.

Concurrent employment

If a worker is employed in more than one job at the time they sustain an injury, any jobs other than the job in the course of which the injury arose (“primary job”) are considered secondary employment.

The average weekly earnings are calculated for all secondary employment in the same way as average weekly earnings are calculated for the primary job.

The earnings and earning periods for each of the jobs are determined separately. The average weekly earnings for each employment are then added together to determine PIAWE.

John sustained a severe laceration injury on 27 October 2019 while employed as a cellar door salesperson. The injury resulted in an admission to hospital and a brief period of rehabilitation. John had been employed in this role for more than 52 weeks when he was injured.

John also had a second job as a part time senior editor grade 2, and he had been employed in that role for 16 weeks before the injury.

John had no capacity to work in either job, and the insurer calculated his PIAWE based on the earnings from both jobs. John took no unpaid leave and had no financially material change in earnings circumstances in either of his jobs.

Job one: Relevant earning period = 52 weeks

Period of employment for job one is from 28 October 2018 to 26 October 2019.

Job two: Relevant earning period = 15.9 weeks

From 28 October 2018 to 7 July 2019, employment for job two not commenced. Period of employment job two is from 8 July to 26 October 2019

John’s earnings for his first job were calculated over a 52-week period.

As John was only employed in his second job for 15.9 weeks, his earnings for that job are calculated over a 16-week period.

John’s PIAWE was calculated as the sum of the weekly amounts earned in both his primary and secondary employment.

Wes sustained an injury on 18 November 2019 while employed as a Hedge Fund Manager. He was diagnosed with a fracture to his right arm, resulting in an admission to hospital and a brief period of rehabilitation. Wes had been employed in this role for 16 weeks when he was injured.

Wes also had a second job where he worked as a part time Policy Officer, and he had been employed in that role for more than 52 weeks. When Wes commenced his job as a Hedge Fund Manager, he reduced his hours in the Policy Officer role from full time to 14 hours per week to accommodate his new job.

After his injury, Wes had no capacity to work in either job, and the insurer calculated his PIAWE based on the earnings from both jobs. Wes took no unpaid leave in either job but did have a financially material change in earnings circumstances in his secondary employment when he reduced his hours.

Job one: Relevant earning period = 16 weeks

Period of employment for job one is from 29 July 2019 to 17 November 2019.

Job two: Relevant earning period = 16 weeks

Period of employment for job two - adjusted earning period of 29 July 2019 to 17 November 2019.

Wes’s earnings for his first job were calculated over a 16-week period.

Wes’s earnings for his second job were also calculated over a 16-week period.

Even though Wes was employed in his second job for more than 52 weeks, the earning period for his second job was adjusted to reflect a financially material change in earnings circumstances once he reduced his hours from full-time to part-time employment as a Policy Officer.

Short term workers

Workers who have been continuously employed by the same employer for less than four weeks before their injury may have their PIAWE calculated by having regard to the weekly earnings they could have expected to earn in that employment in the 52-weeks after the injury (see Schedule 3, clause 4 of the 1987 Act).

When considering prospective earnings, the insurer is to take the following into account:

  • any contract of employment (in writing or implied) in place before the date or injury
  • any award or enterprise bargaining agreement for the worker
  • pre-injury hours worked and earnings received during the 52 weeks prior to the injury.

Should the above points be of limited assistance, regard can be given to the average weekly amount earned by others performing similar work as the worker (whether or not with the same employer), during the 52-weeks before the injury.

A short-term worker may also have their PIAWE calculated using the relevant earning period before their date of injury.

Note: Before considering which option to use for a short-term worker, the insurer should take into consideration which option is the fairest approach for the worker.

See clause 8F of the 2016 Regulation.

Dorothy had been continuously employed for less than four days as a casual shop assistant before she sustained her injury.

She commenced work on a Monday and worked for six hours that day. She worked on Tuesday and Wednesday for 7.6 hours each day. On the fourth day of her employment she slipped and fell, fracturing her arm.

Dorothy was paid at the casual hourly rate of $25.99 per hour. She received no allowances or non-monetary benefits.

As Dorothy had been continuously employed for less than four weeks, the insurer determined her PIAWE based on what she could have expected to have earned in that employment in the 52 weeks after her injury. The insurer chose this option due to her very short relevant earning period. Dorothy did not have a written contract of employment, but she was paid in accordance with the General Retail Industry Award 2010. The insurer spoke to the employer who confirmed that it was expected that Dorothy would have worked 7.6 hours per day for 5 days during the week, but not on weekends.

The insurer calculated Dorothy’s PIAWE to be:

5 days x 7.6 hours x $25.99 = $987.62

The insurer determined Dorothy’s PIAWE to be $987.62 per week based on the above calculation.

Timothy had been continuously employed for 3 weeks as a casual shop assistant.

He was called in to work shifts based on the employer’s requirements. During those 3 weeks, he worked day shifts (8 week days and 2 Sundays). Each shift was 6 hours long. He earned $25.99 per hour (including casual loading) during the week and $38.46 per hour (including casual and shift loadings) on Sundays. Timothy received no other allowances or non-monetary benefits.

On his last shift, he fell off a ladder fracturing his wrist. The initial notification of injury was provided to the insurer and the insurer needed to determine Timothy’s PIAWE to commence weekly payments.

Although Timothy had been continuously employed for less than four weeks, the insurer chose to calculate his PIAWE based on his pre-injury earnings. The insurer made this choice as:

  • there was no written contract of employment for Timothy and while he was paid under an award, he and his employer disagreed about the expectation of his work pattern post-injury, and
  • Timothy had been employed for long enough for the insurer to fairly determine average weekly earnings.

The insurer calculates Timothy’s PIAWE for the 3-week period as follows:

  • For the weekdays: 8 days × 6 hours × $25.99 = $1,247.52
  • For the Sundays: 2 days × 6 hours × $38.46 = $461.52
  • Total earnings:  $1,247.52 + $461.52 = $1,709.04

PIAWE:  $1,709.04 ÷ 3 = $569.68

The insurer determined Timothy’s PIAWE to be $569.68 per week based on the above calculation.

Apprentices, trainees and young people

Some workers are entitled to incremental earning increases at certain ages or stages during their employment (see Schedule 3, clause 5 to the 1987 Act).

This includes:

  • workers under the age of 21
  • apprentices, or
  • trainees for the purposes of becoming qualified to carry on an occupation to which the contract of employment relates.

For these workers, PIAWE is to be recalculated at each age or stage in accordance with what they would have been entitled to receive, had they not become injured and continued in that employment.

Insurers are to assess the considerations listed in the table below as outlined in Table 10.1 in Part 10 of the Guidelines.

ConsiderationDetail
The relevant Award or Enterprise Bargaining Agreement (EBA)If the worker is paid in accordance with an Award or EBA then the hourly base rate of pay and any applicable penalty rates and allowances are to be used.
A comparable relevant Award or EBAIf the worker is not paid in accordance with an Award or EBA, however there is a similar relevant Award or EBA that could apply to the worker, this may be used.
Comparable average earningsWhere no Award or EBA applies to the worker a rate can be determined by reference to the average weekly amount earned by other workers in the same employment for the performance of similar work.

The rate determined is to be based on the date the amount is to be applied.

No applicable rate for a worker who has reached 21 years

If there is no rate applicable to a worker who has reached the age of 21 years, the worker is entitled to receive a rate which is based on a worker who has reached the age of 21 years who performs similar work to the worker in the same employment as the injured worker. If such information is not available, an insurer may determine a rate for these workers based on a rate for a worker who has reached the age of 21 years in a similar but not necessarily in the same employment as the injured worker.

For the purposes of comparison, consideration should be given to the average weekly earnings received by workers performing similar work as the worker during the 52 weeks before they reached the age of 21 years. This rate will be determined based on rates current at the time.

If it is not possible to establish a comparable rate the maximum weekly compensation amount is to be used - see clause 8G of the 2016 Regulation. Note that where the maximum is to be used as PIAWE, the weekly payment formula applies to this rate (that is, taking 95% or 80% of the maximum weekly amount).

The Labour Market Insights website is a useful resource for determining a rate in a similar industry.

Minimum PIAWE

The minimum PIAWE is $155 and is set by clause 8AB of the 2016 Regulation. This amount is not indexed.

If a worker’s PIAWE is calculated to be lower than the minimum PIAWE ($155), then the minimum PIAWE is to be set as the worker’s PIAWE. The minimum PIAWE is not to be used as an interim PIAWE until an insurer has sufficient information to determine PIAWE, unless the insurer has evidence that the worker's PIAWE is likely to be less than $155 per week.

PIAWE Agreement

A worker and employer may reach agreement about the worker's PIAWE. If the insurer is satisfied that such an agreement reasonably reflects the worker's PIAWE and is otherwise fair and reasonable, the insurer must approve and give effect to that agreement. See Part 4, Division 4 of the 2016 Regulation.

If the worker has more than one job when they sustain their injury, the worker and the employer for the job in which the worker was injured may reach agreement about average weekly earnings for multiple jobs.

Agreement workflow

The agreement workflow describes the pre-injury average weekly earnings agreement process and timeframes.  Once an injury is notified to the insurer, and weekly payments are payable, the insurer is to commence weekly payments within 7 days from notification.  If the employer and worker do not reach an agreement as to the amount of pre-injury average weekly earnings, the insurer makes a work capacity decision about pre-injury average weekly earnings. If a worker and employer reach agreement, the agreement application must reach the insurer by day 5 from notification of injury.  The insurer then has 7 days from receipt to determine the application. The insurer may approve the application if it meets the necessary criteria, or they may refuse to approve the application.  If they refuse to approve the application, they must make a work capacity decision. If the insurer approves the application, the agreement takes effect.  The worker or employer may later withdraw from the agreement after it has taken effect.  If so, the insurer must make a work capacity decision to determine pre-injury average weekly earnings. If a non-monetary benefit is withdrawn after the agreement has taken effect, the worker and employer may agree a value of the non-monetary benefit and the original agreement is varied to include the value of the non-monetary benefit,  if the worker and employer do not reach agreement about the value of the non-monetary benefit, the insurer must make a work capacity decision to determine pre-injury average weekly earnings.

Application for approval

A written application for approval is to be made by either the worker or the employer within 5 days of notification of the injury to the insurer (see clause 8J of the 2016 Regulation).

The application must include:

  • the agreed PIAWE amount*
  • the date of the agreement
  • the worker's name, injury date and claim number
  • the employer's name
  • the name and contact details of the person authorised by the employer to enter into the agreement
  • details of any other employment in which the worker is engaged
  • any evidence which supports the agreement (e.g recent payslips or contract of employment)
  • any other information the employer or worker considers were taken into account in reaching the agreement
  • acknowledgement of consent to the agreement

* The agreed PIAWE remains subject to minimum PIAWE.

SIRA has an application for approval of a PIAWE agreement form, which can be used by the worker and employer to meet the above requirements.

The worker's and employer's consent can be provided by a physical signature or electronic signature on a single application document. It may also be provided by email, as long as the insurer is satisfied that both the worker and employer have given their express consent to the agreement (for example, the consent was sent in an unbroken chain of emails together with the information required in clause 8J of the 2016 Regulation).

Approval of the agreement

The insurer is to approve or refuse to approve the agreement within seven days of receiving the application. After the application is determined, the insurer must notify the worker and employer of the outcome of the determination. The approval of the agreement is not a work capacity decision.

The insurer is to approve the agreement if they are satisfied that the agreed amount reasonably reflects the worker’s PIAWE and that the agreement is fair and reasonable.

PIAWE agreements were designed to be less administratively burdensome by easing the requirement for insurers to gather pay, leave and employment-related information to calculate PIAWE. The insurer is to decide what supporting information they require to be satisfied for approval.

If the insurer has disputed liability, they cease to have an obligation to approve or refuse the agreement.

If the insurer has a reasonable excuse for not commencing weekly payments, the insurer has seven days to approve or refuse to approve the agreement after the earlier of:

  • ceasing to have a reasonable excuse, or
  • the claim being accepted.

If a worker is under legal incapacity, an insurer must not approve a PIAWE agreement (see clause 8K(5) of the 2016 Regulation). A person under legal incapacity includes:

(a) a child under the age of 18 years,

(b) an involuntary patient or forensic patient within the meaning of the Mental Health Act 2007,

(c) a person under guardianship within the meaning of the Guardianship Act 1987,

(d) a protected person within the meaning of the NSW Trustee and Guardian Act 2009, and

(e) an incommunicate person, being a person who has such a physical or mental disability that prevents the person from receiving communications, or expressing their will, in relation to their property or affairs.

The insurer still has the obligation to commence weekly payments within 7 days of initial notification. The agreed amount (not yet approved by the insurer) can be used to make weekly payments until the agreement has been determined. This is an interim payment decision and is not a work capacity decision.

An insurer cannot make a work capacity decision about PIAWE before the application for the agreement is determined, and an insurer cannot approve the application if it was made after a work capacity decision about PIAWE was made.

Hannah sustained an injury while working as full-time Veterinary Nurse. She consistently works 38 hours per week and earns $941.10 per week.

When waiting in hospital to be seen after she injured herself at work, she reviewed SIRA's new claims management guide to understand the claims journey and what to do next.

She completed the application for approval of an agreement form (which she found on SIRA's website). When she got home from hospital, she attached four of her most recent payslips and forwarded this information to her employer. Her employer agreed, and the form was promptly submitted to the insurer within 4 days of her injury.

The insurer received the application for approval of an agreement, and following discussion with both Hannah and the employer, the insurer approved the agreement on the basis that they were satisfied the agreed amount reasonably reflected her earnings.

The insurer approved the agreement within 7 days after receiving the application, and commenced provisional weekly payments using the agreed amount as Hannah’s PIAWE.

After George sustained a work injury the insurer informed George and his employer (Simon) that they may reach an agreement about George’s PIAWE. The insurer informed George that he can contact his union or IRO if he requires assistance or advice regarding his claim and PIAWE agreement.

Simon suggested to George that to expedite the process they should average his two most recent payslips to determine his PIAWE. George agreed, and Simon applied to the insurer for approval of the agreement, providing the two recent payslips as supporting evidence.

However, George had recently gone through a difficult time. Four weeks before his injury, George’s brother died, and he took two weeks of leave. Once he returned to work, he performed no overtime as he had to make personal arrangements for his brother’s family.

The insurer examined the agreement application and payslips and contacted Simon. The insurer asked Simon whether the amount of leave taken by George was unusual for the period and whether George normally performed any overtime. Simon informed the insurer that the recent leave taken by George was out of the ordinary, and that he would normally perform overtime every week.

The insurer told Simon that they could not approve the agreement, as they did not consider it reasonably reflected his PIAWE for the 52 weeks before the injury. The insurer calculated George's PIAWE and communicated this by way of a work capacity decision.

Variation of the agreement

An agreement about PIAWE may only be made once. However, the agreement may be varied to include the cash value of a non-monetary benefit where it is withdrawn after injury.

Withdrawal of the agreement

The worker or employer can withdraw from the agreement at any time by giving written notice to the other party and to the insurer.

Following this, the insurer is to make a work capacity decision to determine PIAWE within 7 days. They must provide the worker and employer with written notice of the withdrawal from the agreement and advise the amount of the new PIAWE in a work capacity decision notice.

If the new PIAWE amount is higher than the PIAWE amount in the withdrawn agreement, the worker is to be paid the back payment in accordance with the following formula:

X – Y = Z

Where:

X is the amount of weekly compensation the worker should have received (based on the new PIAWE) from the date the worker first became entitled to weekly payments up to the date in which the last weekly payment was made.

Y is the amount of weekly compensation already paid to the worker over the same period.

Z is the amount owed to the worker over the same period (that is, the “adjustment payment”).

All future payments are to be based on the new PIAWE as determined by the insurer.

Interim PIAWE

To enable weekly payments to commence within 7 days of notification, insurers can use an 'interim PIAWE' if there is likely to be a delay in determining a PIAWE agreement or in receiving all the information to determine PIAWE.

Interim payment decision

If an insurer is not able to approve or refuse to approve an application for agreement by day 7 from initial notification of injury, they may give effect to the agreed amount in the application. This is an interim payment decision and allows the insurer to make weekly payments based on the agreed amount of PIAWE until the application for approval of the agreement has been determined.

The same timeframes continue to apply to approval of the agreement. An interim payment decision is not a work capacity decision. If an insurer subsequently refuses to approve the agreement, they are to determine PIAWE by a work capacity decision.

If the calculated PIAWE is higher than the amount in the agreement, the new rate and the outstanding adjustment payment is to be made to the worker within 14 days from the date of the work capacity decision (see clause 8N to the 2016 Regulation).

Work capacity decision

Insurers should request pay information from the employer as soon as possible. The insurer can inform the employer of their obligation under section 264(2) of the 1998 Act, which requires employers to provide information to insurers within seven days of the insurer’s request.

If an insurer determines that there is likely to be a delay in receiving sufficient information to determine PIAWE to enable weekly payments to commence within seven days of notification, they should request supporting information from the worker to inform an interim PIAWE calculation (see Standard of Practice 7: Interim pre-injury average weekly earnings). Insurers can also consider relevant Awards found on the Fair Work website.

The amount of the interim PIAWE and how that amount was determined must be communicated to the worker by way of a work capacity decision (see section 43(1)(d) of the 1987 Act).

The worker should be informed that this PIAWE is an interim amount until sufficient information is provided to enable the correct PIAWE to be determined.

The minimum PIAWE is not to be used as an interim PIAWE unless the insurer is satisfied that a worker's PIAWE will be less than $155 per week.

The insurer should also advise the worker that an adjustment payment may be payable if PIAWE is later determined to be higher than the interim amount. The new rate and the outstanding adjustment payment must be made to the worker within 14 days from the date of the work capacity decision (see clause 8N to the 2016 Regulation).

Note: An insurer is to continue to engage with the employer to obtain the missing information to determine the worker’s correct PIAWE.

Where there is an interim PIAWE, and the employer does not respond to insurer requests for information, the insurer may contact SIRA on 13 10 50 to determine whether further action is required.

Self-employment and working directors

PIAWE for self-employed workers and working directors is calculated as it would be for all eligible workers. However, the types of evidence gathered may be different based on the worker’s earning circumstances. Business activity statements reflect business activity only and are therefore not useful, and payslips are generally not available. Useful information may include:

  • pay as you go (PAYG) summaries
  • group certificates/tax returns
  • bank statements.

Indexation of PIAWE

Indexation of a worker’s PIAWE is considered on 1 April and 1 October each year (see Part 3, Division 6A of the 1987 Act).

Refer to Insurer guidance GN 5.13 Indexation for more information on how indexation is calculated for weekly payments.

Gathering information for the PIAWE calculation

The insurer needs to gather as much information as possible to calculate the correct entitlement for the worker. This may include:

  • a completed PIAWE form
  • copies of payslips or any available payroll records covering the relevant earning period
  • any relevant Fair Work instrument, contract of employment or enterprise bargaining agreement
  • leave records
  • tax returns
  • any other supporting documentation specific to a worker’s employment circumstances, including dates and amounts relating to ongoing changes in earnings during the relevant earning period.

If the worker has more than one job at the time of injury, the above information (where relevant) should be gathered for the worker's employment with all employers.
