NSW has confirmed 180 COVID-19 cases and three deaths as six NSW public schools are closed due to cases of the virus.

NSW Health said on Monday there were 202 people with the virus in the state’s hospitals, including 30 in intensive care.

In the 24-hour reporting period to 8pm on Sunday there were 45,405 tests conducted.

Nearly 95 per cent (94.4 per cent) of adults have had their first vaccine while 91.8 per cent of people 16 and older have had two doses.

Some 75.4 per cent of people aged 12-15 have had two doses of a COVID-19 vaccine, while 81 per cent of them have had their first jab.

On Sunday, NSW Premier Dominic Perrottet warned unvaccinated people would not be granted freedoms any earlier than December 15, despite thousands rallying against vaccination requirements.

The measures were “tailored to keep people safe and that’s what we’re focused on”, Mr Perrottet said a day after 10,000 unmasked protesters descended on Sydney.

Meanwhile, six NSW public schools were closed on Monday due to a COVID case in their community.

NSW Health’s Dr Jeremy McAnulty said on Sunday there had been multiple cases in schools across the state and he urged parents to remain vigilant to help protect others.

“Symptoms in children can be quite mild and not obvious so if they get any symptoms at all please take your children to a testing clinic,” he said.
