'Rapid increase' in Canterbury-Bankstown cases shows Sydney's COVID-19 outbreak on the move

The Delta outbreak, which began in Sydney's eastern suburbs 54 days ago, has been concentrated around Fairfield, in the city's south-west, for several weeks.

But 92 of 319 new cases recorded in the 24 hours to 8:00pm Friday were from the Canterbury-Bankstown local government area (LGA), sparking warnings the virus was on the move again.

NSW Health Minister Brad Hazzard said there had been "a rapid increase" in COVID infections in the LGA this week, with around 500 new cases identified.
