There have been two new cases of COVID-19 diagnosed in the past 24 hours, bringing the total number of cases in NSW to 3,092.
Both of the new cases are in returned travellers who are now in quarantine hotels, NSW Health said.
NSW Premier Gladys Berejiklian did not give a morning media update on Tuesday, with the department releasing the data in a statement accompanied by a recording of Dr Jeremy McAnulty.
Transport minister Andrew Constance and Education Minister Sarah Mitchell fronted the media to announce that commuters will be monitored by CCTV to check social distancing is maintained on trains, and parise schools for a smooth first day back.
A new team of 80 transport workers will monitor the recordings collected by 11,000 cameras across the network.
"We're not here to be COVID cops, we're here to protect and save lives," Mr Constance said.
Also in public transport news, the Minister for Regional Roads and Transport Paul Toole announced extra staff were being deployed in the regions to assist passengers and ramp up cleaning across the network.
"Additional customer support and security staff will be deployed to help customers move through stations safely and monitor physical distancing, including at busy regional hubs such as Lismore, Shellharbour, Bathurst, Nowra, Tweed, Albury and Bega," he said.
Ms Mitchell said she was pleased with how the first day of school had gone, and reported a 14 per cent absentee rate - which is only slightly higher than normal, pre-COVID rates.
She also said schools closing - as seen at Waverley College in Sydney's East which was evacuated when a school boy reportedly tested positively on Tuesday - would become normal throughout the pandemic.
"We are living through a pandemic and there will be occasions from time to time when we do have a positive case that affects the school community," she said.
She said there were good processes in place to close schools when needed.
According to NSW Health, there were 4,621 tests carried out in the 24 hours to 8pm on Monday, compared with 4,783 in the previous 24 hours.
There are currently 85 COVID-19 cases being treated by NSW Health. This includes one person being treated in an intensive care unit.
There are now 2,661 people in NSW who have recovered from COVID-19.
