NSW is in a critical phase of its two week lockdown, with cases uncovered in the coming days to help determine if stay-at-home orders affecting millions of people have to be extended.
Premier Gladys Berejiklian told reporters on Saturday it was "too soon" to tell whether the lockdown of Greater Sydney, the Central Coast, Blue Mountains and Wollongong will be extended beyond July 9.
The state recorded 35 local virus cases in the 24 hours to 8pm Friday, bringing the current outbreak to 261 cases.
While it's the highest daily case number since the state's first wave in early 2020, the majority of cases have been in isolation for their entire infectious period.
"If all of us continue to do the right thing, we're able to leave the lockdown in a timely way. The next few days will be telling," Ms Berejiklian said.
On Friday, she said authorities wanted to see a rise in the proportion of new cases that were already in isolation, with the next several days critical to the lockdown effort.
Authorities listed a string of new exposure sites across Sydney on Friday and Saturday.
The latest cases show the epicentre of the outbreak has shifted from the city's east, to the western and southwestern suburbs.
Anyone who has been in the centre of Auburn in Sydney's west since June 27 is being told to get tested, even if they don't have symptoms.
Meanwhile NSW has lifted stay-at-home orders for travellers from Western Australia, the Northern Territory and parts of Queensland as restrictions in those states and territories have eased.
But visitors to NSW from Brisbane and Moreton Bay must remain at home, as must anyone in the Greater Sydney area.
