Three people have tested positive to COVID-19 in NSW overnight, after 4200 people were tested in 24-hours.
One was a returning traveller who tested positive in quarantine, and two - a 71-year-old woman from Sydney's eastern suburbs and an 85-year-old man from central Sydney - were locally acquired.
The total confirmed cases in the state now stands at 3090, while the death toll remains at 50.
One person is being treated in an intensive care unit, Chief Health Officer Dr Kerry Chant said, and 90 are being treated by NSW Health in total.
At her morning media conference, Premier Gladys Berejiklian also highlighted that it was a "special day for all students and parents and school communities across the state" and said she was pleased with the way people were conducting themselves as students returned to school.
She said sufficient numbers of students had been walking, getting dropped off or catching a dedicated school service, which meant public transport hadn't been overburdened by the extra load.
Early accounts indicated that absentee rates were not much higher than the normal pre-COVID rate, Ms Berejiklian said, thanking most parents for taking the government's advice.
She said a final attendance figure would be forthcoming later in the day, but expected it to be slightly lower than usual due to people being more cautious about minor illnesses like colds.
"Ordinarily, if a child had a sniffle or a symptom you'd be likely to tell them to go to school and we're grateful that parents aren't doing that," she said.
Asked about the small percentage of people who were continuing to keep their children home due to fears about contracting the disease, Ms Berejiklian said parents still keeping their kids home would have to face the consequences fo doing so.
"From what I've seen thats a very small proportion of parents," she said.
"I appreciate that small percentage of parents will make that choice, but all choices come with consequences and that's a matter for them."
The Premier was also quizzed about the reopening of gyms, and said the state was not in the position to make an announcement about their return.
She said there had been "a lot of discussion" regarding the return of gyms and other fitness centres, but that they presented different concerns to businesses like cafes and restaurants.
"Obviously frequent use of equipment at short intervals poses a threat so we're working with the industry on a safe return there [but] we're not in a position to make an announcement yet," she said.
