Where a worker is entitled to receive weekly compensation payments, these payments are calculated by the insurer using a formula and the worker's pre-injury average weekly earnings (PIAWE).

For workers injured on or after 21 October 2019, PIAWE means the weekly average of the gross earnings received by the worker for work in any employment in which the worker was engaged at the time of the injury. See 'Pre-injury average weekly earnings'.

A reference to PIAWE for workers injured before 21 October 2019, means the amount determined in accordance with section 44C of the Workers Compensation Act 1987. See 'Pre-injury weekly earnings for workers injured before 21 October 2019'.
