NSW Health officials have stepped up hotel quarantine testing procedures despite the state bringing up its 20th straight day without a positive case.
The zero local case result came after 12,521 tests in 24 hours, with an additional two cases also detected in returning international travellers.
NSW Health said they would be ramping up checks on people after they left hotel quarantine and asking them to get tested two days after they departed.
Contact tracers will call the returned traveller 48 hours after their quarantine period ends and ask them to attend their local testing clinic.
“If travellers being tested on day 16 are asymptomatic, they will not have to isolate further due to the lower risk of them returning a positive result,” NSW Health said.
Authorities are also targeting people who have recently been in Victoria.
Those entering NSW via Victoria via air and rail are required to complete a passenger declaration form.
Providing false information could result in an on-the-spot fine, NSW Health said.
Non-NSW residents who have visited the public exposure sites listed by the Victorian Department of Health and Human Services are banned from entering the state.
“NSW Health continues to urge people to come forward for testing with even the mildest of cold-like symptoms that could signal COVID-19, such as a sore throat, cough, fever or runny nose,” NSW Health said.
“After testing, you must remain in isolation until a negative result is received.”
Meanwhile, additional cleaning squads have been rolled out across the Sydney CBD transport network.
Transport Minister Andrew Constance said roving teams at Central, Town Hall, Wynyard, Circular Quay and Martin Place were cleaning touch points and handing out free masks.
“In addition to the cleaners on our services, we have now rolled out additional cleaning squads to keep stops, waiting areas and even bike racks clean to help stop the spread of COVID-19,” Mr Constance said.
“More than 1,000 touch points are cleaned each shift at Central, Town Hall, Wynyard, Circular Quay and Martin Place, and more than 92,000 masks have been handed out to customers since the squads first popped up during the Northern Beaches outbreak.
“The teams can be deployed quickly to areas where there has been a COVID-19 breakout or where a major event is taking place, like the SCG for the cricket.”
