Residents of Sydney and surrounds should learn on Wednesday whether their lockdown will be extended beyond Friday, NSW premier Gladys Berejiklian says.
NSW recorded 18 new COVID-19 cases in the 24 hours to 8pm on Monday, with seven in the community for at least some of their infectious period.
"The lockdown is having its desired effect to date, no doubt about that," Ms Berejiklian said on Tuesday. "
But it's still concerning that a number of cases are remaining infectious in the community for that period of time."
The premier said she would be talking with health experts throughout the day and evening, and hopes to tell the community on Wednesday "what next week looks like".
The stay-at-home orders for more than five million people in Greater Sydney, Wollongong, Shellharbour, the Central Coast and the Blue Mountains regions are due to end at midnight on July 9.
Ms Berejiklian said the length of the lockdown will be informed by the fact that the NSW government wants this to be the state's last lockdown.
