NSW has recorded 22,255 new COVID-19 cases and 16 deaths in the 24 hours to 4pm.
Yesterday, the state reported 24,151 new infections and 15 lives lost.
There are 1437 COVID-19 patients in hospital, with 48 in ICU.
Hospitalisation numbers are down on yesterday, when 1444 patients were being cared for with 51 in ICU.
Of the new cases, 12,569 came from positive rapid antigen tests while 9686 came from PCR testing.
Today's 22,255 new cases come as thousands of NSW health workers walk off the job, calling for a pay rise in an ongoing industrial dispute with the government.
Under the state's wages cap, public sector pay increases cannot legally exceed 2.5 per cent but the Health Services Union maintains this is not enough with inflation running at 3.5 per cent.
The union is campaigning for a 5.5 per cent increase "to account for the impact of the pandemic and the surging cost of living".
