NSW announced 35 new local COVID-19 cases yesterday, two of which were aged care residents at a Sydney nursing home where three residents have already tested positive.

The state’s Chief Health Officer Dr Kerry Grant would not comment on the likelihood of extending the 14-day lockdown beyond its July 9 deadline until she had “looked at all the data”.

She said there had been a record number of tests (58,373) for a Sunday but asked the public not to get “fatigued” with testing.

Premier Gladys Berejiklian said this second week of lockdown was “critical” for getting on top of the outbreak, which has reached 312 people since emerging in Bondi in mid-June.

“The lockdown certainly has been effective in not doubling and tripling the figures that we were worried about,” Berejiklian told reporters.
