Rates for compulsory workers’ compensation insurance in WA are set for an overall increase of 4% for the next financial year.

WorkCover WA says the average recommended premium rates will be 1.704% of total wages, up from 1.638% in the current financial year.

The increase will come into effect from 4pm on June 30.

“Western Australian recommended premium rates vary from year to year depending on a range of factors, and in the context of the COVID-19 pandemic there was a small decrease in the recommended rates last year,” CEO Chris White said.

“Key drivers of the 2021/22 rate include longer claim durations and associated costs, offset by wage increases and declining claim numbers.

“The increase will ensure sufficient reserves to cover the cost of workers’ compensation claims over the coming year.”

The rates are based on independent assessment by the scheme actuary, PricewaterhouseCoopers, and take into account the number and cost of workers’ compensation claims, together with external impacts such as movements in interest rates and wages.
