West Australians are finding more jobs than ever in the mining industry, but the state's gender pay gap is the "worst in the Australia", according to the latest figures released by the state government.

The average number of men and women employed in the mining sector jumped by about 12,000 people for the last financial year on the back of a $30 billion increase in mineral and petroleum sales compared to the previous year.

But despite an overall increase in the number of jobs on offer throughout the state, WA's gender pay gap sits at 21.8 per cent, according to the state government's 2019 Women’s Report Card released by Women's Interests Minister Simone McGurk on Monday morning.

Gender pay gap is calculated by subtracting female average earnings from male average earnings and dividing the result by male average earnings.
