NSW has recorded 633 new locally acquired COVID-19 cases in the 24 hours to 8:00 pm yesterday.
It is the largest daily total every recorded in the state.
550 of the new cases were in Western and south-west Sydney.
NSW also recorded three deaths – a man in his 60s, as well as two men from Western Sydney in their 70s.
Victoria has recorded 24 new locally acquired COVID-19 cases, 18 of whom were in quarantine while infectious.
Melbourne’s lockdown, which will run until September 2, has been tightened further with the cancellation of late-night weekend public transport.
No trains, trams or buses will run between 1:00am and 5:00am on Saturdays and 1:00am and 6:00am on Sundays for the next two weeks.
The announcement of the cancellation, which the government said was the same setting in place during last year’s second wave, comes a day after playgrounds were closed and a curfew was put in place.
