NSW has recorded 199 new locally-acquired COVID-19 infections, with at least 50 of them infectious in the community.
Of the local cases reported on Tuesday, 88 are linked to a known case or cluster. The source of infection for 111 cases is still under investigation.
NSW Premier Gladys Berejiklian said workplaces and households were still the main places where the virus was transmitting.
“It is still concentrating within those eight local government areas of concern,” Ms Berejiklian told reporters.
“Don’t go into those eight local government areas unless absolutely necessary.
“You might live in an adjoining suburb and go shopping in those communities – consider going elsewhere to make sure that the virus doesn’t spread into other communities.”
The eight LGAs of concern are Blacktown, Campbelltown, Canterbury-Bankstown, Cumberland, Fairfield, Georges River, Liverpool and Parramatta.
Chief Health Officer Dr Kerry Chant said there were 104,536 tests.
“Whilst we have focused significantly on the affected LGAs, it’s important that we don’t have complacency across other local government areas,” she said.
