The Australian Bureau of Statistics has released new data on jobs and wages based on Single Touch Payroll data from the Australian Taxation Office.
The new statistics help to further paint the picture of the economic impact of COVID-19.

Total wages paid by businesses decreased by 6.7% over the period.

"The largest impact of net job losses, in percentage terms, was for people aged under 20, for whom jobs decreased by 9.9%.
"Tasmania and Victoria had the largest decreases in jobs, down by 7.3% and 6.8%.
"The Accommodation and food services industry saw the largest reduction in jobs (decreasing by 25.6%), followed by the Arts and recreation services industry (decreasing by 18.7%).
