NSW COVID: Daily case numbers at 110 following record day of testing, Premier Gladys Berejiklian says

110 new cases in NSW, 43 out in the community

NSW could be heading for longer lockdowns and further stay-at-home orders as the number of people in the community while infectious with COVID-19 remains uncomfortably high.

Premier Gladys Berejiklian said there were 110 new locally acquired cases of COVID-10 in the 24 hours to 8pm on Tuesday, with 43 in the community while infectious.

Ms Berejiklian said nearly 84,000 people were tested on Tuesday - the highest number of tests to date.

"This is a great result, and one we need to keep up in the next few weeks," she said. "It means we are scooping up all the cases we can find.

"Had we not gone into the lockdown a couple of weeks ago, that number would undoubtedly been thousands and thousands. We have done well.

"Our vaccination rates are so low and yet we have done so well in stemming the virus. Now we need to quash it."

The higher number of tests had helped to identity the "high number" of cases in the 24 hours to 8pm on Tuesday.

NSW Health's Dr Jeremy McAnulty said there were 106 COVID-19 patients in hospital, 23 in intensive care, and 11 requiring ventilation.

"We are now seeing cases in Western Sydney increased," he said.
