The number of new infections for the 24 hours to 8pm on Monday is an increase of more than 5000 from the previous day.

The 11 people who died across the state follow two record days for the NSW death toll.

According to NSW Health figures released on Tuesday morning, there are 2186 people in hospital and 170 patients in intensive care units.

There are 315,785 active COVID-19 cases in NSW.

The health authority reported 71,325 tests for the 24-hour period, but rapid antigen tests are not yet being registered.

Meanwhile, the NSW Nurses and Midwives' Association (NSWNMA) is calling on Prime Minister Scott Morrison to urgently increase resources in the aged care sector.

The union says residents and staff are being placed at risk due to a severe lack of preparation by the sector and federal government.

Acting general secretary Shaye Candish said nurses working in aged care were desperate for intervention.

"During the Delta outbreak last year, COVID-19 positive residents were transferred to local public hospitals to minimise cross infection and to ensure acute care needs were met. We also often saw public sector resources sent into the aged care facilities to achieve the same outcome. This is currently not the case," she said.
