NSW has recorded 44 new local COVID-19 cases, with 29 of those either partially or fully infectious in the community.
Premier Gladys Berejiklian said the number of cases not in complete isolation was concerning because it meant higher cases in the coming days.
She said it would mean lockdown restrictions would be further tightened across Greater Sydney from 5pm today.
“Until we get to zero or close to zero, we cannot ease restrictions,” she told reporters on Friday.
“In fact, based on the health advice the government received late last night and early this morning, New South Wales will be further tightening restrictions in those areas that already have stay-at-home orders.”
