About this month’s system performance results


Return to work (RTW) rates continue to deteriorate in September 2019

RTW is a key indicator of the Workers Compensation system performance and health. Research has indicated that returning to work makes an important contribution to a worker’s recovery, it is important to employers and it is important for a viable and sustainable Workers Compensation system.

Across the system the RTW rate is measured using work status codes at 4 weeks, 13 weeks and 26 weeks. As shown in the following table the RTW rate at 4 weeks has dropped by 6.8 percentage points since September 2018. Similarly, the RTW rate at 13 weeks for the same period deteriorated by 6.5 percentage points and at 26 weeks by 7 percentage points.

The deterioration in RTW across the system is largely driven by the performance of the NI and has been the subject of a compliance and performance review.

The self-insurers RTW performance is deteriorating to a lesser degree and SIRA is currently analysing this. While at a very preliminary stage, initial exploration reveals the RTW performance is impacted by several variables including data quality and completeness from insurers. Once SIRA has completed the analysis we will report more fully on this aspect of the system performance.

In addition to RTW rates being calculated using work status code data, SIRA has analysed the number of workers who are receiving weekly benefits and the costs for each month. The results show a diminished RTW rate and increasing weekly payments across the system in September 2019.

The average duration (in days) a worker was receiving weekly benefits in the first six months following an injury in 2013/14 was 23.3 days. This has steadily increased to 27.8 days in 2018/19 as measured at 30 September 2019.

There is an increasing trend in both the amount of weekly payments and the number of active claims (see below). The amount of weekly payments in the 12 months to September 2019 increased by 20% relative to the preceding 12 months. The specialised insurers (weeklies increase of 18%) and the TMF (weeklies increase of 17%) are both showing a similar trend.

There is also a trend in increasing costs for weekly payments made per month, which is consistent with declining return to work rates.


Claim payments and active claim numbers are increasing – driven by weekly payments and increased medical costs and payments.

Claim numbers and active claims

The stability of claim numbers and claim costs is an important measure of the Workers Compensation system stability and viability. An indicator of this stability is the number of active claims in the system (where an active claim is defined as a claim with payment activity within the last three months).

The number of claims reported shows no strong upward trend for the quarter however active claim numbers have increased. Despite claim numbers having no strong upward trend, the number of active claims has increased materially in the September quarter. The NI increase is a 7% increase (September to September) however between March 2019 and September 2019 this increase has been nearly 20%. The annual increase for specialised insurers has been 10% (6% for TMF and 3% for self-insurers). The increase since March has been approximately 5% for the TMF, self and specialised insurers which indicates that the NI data at March was possibly understated (this possibly may be due to the introduction of the NI Guidewire (Nominal Insurer icare Single Platform). There has been a step jump in the number of active claims between June 2019 (about 60,000) and July 2019 (about 65,000). August and September show a continued upward trend.

Claim payments

The payments data is also relatively volatile on a month to month basis. While SIRA values the transparency and timeliness of reporting, there may be payments reported which are understated. SIRA retrospectively adjusts data submissions and/or corrections in insurers subsequent month’s reporting.

Overall claim payments continued to increase with payments totalling $3.3B for the rolling 12 months to September 2019. Total claim payments increased by $296M year on year from September 2018 to September 2019. The primary drivers for this increase were the weekly payments (as referenced above) and the medical payments with total medical spend increasing by 10% ($84M) over the previous period.

Further analysis of medical payments shows that private hospital expenditure increased to $140M ($10M or 7% increase in claims), while surgery expenses increased to $ 110M (an additional $6M in payments). Orthopaedic surgery (excluding spinal surgery) constituted 58% of the total surgery expenses. In addition, the payments for allied health expenses increased with physiotherapy services increasing 13% ($9M in additional payments with service being provided for 8% more claims). Similarly, psychological services increased by 33%, ($8M in additional payments with service being delivered for 24% more claims). The payments for exercise physiologists’ also increased by 23% ($6M in additional payments with service being delivered for 19% more claims).

Rehabilitation services payments show a decline in payments of 18% ($33M less in payments with services being provided to 10% fewer claims).

Customer experience

Enquiries, complaints and disputes were slightly down for September 2019

SIRA and WIRO received 3,177 enquiries and complaints about the NSW Workers Compensation system in September 2019, with a dispute rate of 0.6% on all 99,698 active claims in the system.

About the data in this report

The dashboard reports data from multiple sources to provide insights into the system performance of the NSW Workers Compensation system. The report is structured on SIRA’s performance framework, reporting on performance measures of effectiveness, efficiency, viability, affordability, customer experience, and equity.

SIRA as the regulator of the NSW Workers Compensation system monitors the system regularly and defines parameters of the system in alignment with the glossary and descriptions in the attached table. From time to time there are discussions and presentations from providers within the Workers Compensation ecosystem including insurers, medical and allied health providers etc about these metrics. One such discussion currently within the landscape is that of the definition of active claims.

Methodology, data notes and data sources

The data presented in this report are derived from monthly claims submission data, annual declarations provided to SIRA from NSW workers compensation insurers, the Workers Compensation Commission and the Workers Compensation Independent Review Office.

The financial and cost information in this report is presented in original dollar values with no indexation applied. Costs in the workers compensation scheme are subject to a variety of potential inflationary factors including wage and salary rates, medical fee schedules, statutory benefit indexation and general price inflation. As there is no single index which adjusts for all potential factors, costs have been shown in their original dollar values for simplicity.

The premium value used for the Nominal Insurer in this report is calculated as total premium payable net of GST and levies, such as the dust disease levy and mine safety levy. Premium for self-insurers is deemed premium, calculated as wages covered multiplied by the premium rate applicable for the appropriate industry class. Premium for Government self-insurers (TMF) is the value of the deposit contributions made by each member agency. Premium for specialised insurers is the gross written premium, net of GST and levies, such as the dust disease levy and mine safety levy.

Insurers regularly update claims data based on the progression of a claim. This may result in changing claim details month on month.

Additional efficiency information

System costs – weekly payments

SIRA in the previous reports offered additional data on the Workers Compensation system performance. These additional data sets have been included at the end of the dashboard report to show the following.

  1. The cost to the system of weekly benefits paid per month.
  2. The number of workers receiving weekly benefits per month.
  3. The average duration of weekly benefits paid to workers in the first six months following their injury.
  4. The percentage of workers who have returned to work (including those who received medical benefit only with no lost time), at 4, 13 and 26-week intervals.

As indicated above, analysis of this additional information reveals an upward trend for both the costs associated with deteriorating RTW rates and the number of workers receiving weekly benefits.

The “Claim payment development” chart has again been developed for the August 2019 dashboard. The chart shows claim payments by accident year. That is, comparing payments of accidents occurring in the 2019/20 financial year with the prior accident period at the same stage of development. This chart allows for like for like comparisons across financial years and presented in original dollar values with no indexation applied.

Data source information


Reported claims

Standard terms


Active claim

An active claim is defined as a claim with any payment within a three-month period.

Reportable claims

A reportable claim for workers compensation or work injury damages is a claim that a person has made or is entitled to make under the Workplace Injury Management and Workers Compensation Act 1998. Claims become reportable once they meet certain liability conditions and/or have received payments. For example, the injury or illness may be physical or psychological and employment must be a substantial contributing factor to injury, except for those claims made by police officers, paramedics, fire fighters, volunteer bush fire fighters and emergency and rescue services volunteers for injuries suffered during journeys to and from work or place of volunteering.

Reportable claims include claims from workers whose employer is uninsured. Where a split by insurer segment is shown, claims of uninsured employers are included with the Nominal Insurer segment.


Reportable claims exclude administration error claims, claims closed with zero gross incurred cost, claims shared between two or more workers compensation agents/insurers and the agent/insurer is not responsible for the management of the claims, and claims with payments only for recoveries, vocational programs or invalid payment classification numbers.

Reportable claims also exclude claims for:

  • dust diseases (administered by the Dust Diseases Authority)
  • workers who are self-employed
  • employees of the Australian Government
  • a member of the NSW Police Force who is a contributor to the Police Superannuation Fund under the Police   Regulation (Superannuation) Act 1906.

Records submitted

All records received from insurers across NSW.  This data excludes administration errors.

Lost time

Monthly average, over the last 12 months, of workers who had lost time.

Claim types

Standard terms


Claim types

Claims reported in the reporting month, classified as either 'psychological injuries' for mental disorder claims or 'all non-psychological injuries' for all other claims

Psychological Injury (ies)

The range of psychological conditions for which workers compensation may be paid, including post-traumatic stress disorder, anxiety/stress disorder, clinical depression and short-term shock from exposure to disturbing circumstances.

Return to work

Standard terms


Return to work rate

The Return to work (RTW) rate is the percentage of workers who have been off work as a result of their employment-related injury/disease and have returned to work at different points in time from the date the claim was reported (i.e. 4, 13 and 26 weeks for the SIRA Stats report).

RTW rates are calculated monthly for the last 13 months up to the date of data. The cohort for each RTW measure is based on claims reported in a 12-month period, with a lag to allow for claim development (i.e., the lag for the 4-week measure is 28 days; the lag for the 13-week measure is 91 days; and the lag for the 26-week measure is 182 days).

Calculation method for 4-week measure for November 2018 is given below as an example:

  1. Total number of time lost claimants = Claims   reported from November 2017 to October 2018
  2. Total number of claimants back at work in 28   days (based on work status codes 1, 2, 3 & 4) with any capacity

RTW Rate=b/a multiplied by 100

SIRA identified data quality issues with the accuracy and completeness of data submitted by the Nominal Insurer (NI). The data revealed a significant deterioration in the NI’s RTW performance. To address the data quality and potential performance concerns with the NI, SIRA carried out a Data Quality audit in December 2018 and commenced a Compliance and Performance Review in February 2019. SIRA published the Review and associated documents in December 2019 and the reports are available here.

The Perceived Justice of the Compensation Process series of measures is a scale used to measure workers perceptions of fairness of their workers compensation experience.

The Abridged Return to Work Outcomes Survey: NSW Workers Compensation System (October 2019) included three dimensions (procedural justice, information justice, and interpersonal justice).

  • procedural justice, about the fairness of the procedures used   to determine the outcomes.
  • informational justice, in receiving accurate and timely information about the   rationale for decisions
  • interpersonal justice, on whether they were treated with respect and sensitivity

For each dimension, respondents were asked to rate their level of agreement with a series of statements using a 5-point Likert type rating scale. A higher score denotes a higher level of agreement, or a higher perceived sense of justice / fairness.
