Victoria has once again broken the highest daily coronavirus case record with another 532 new cases overnight.
Premier Daniel Andrews said there had also been six more deaths, including a male in his 50s.
NSW recorded 17 new cases yesterday.
Victorian deputy chief medical officer Nick Coatsworth said it was hoped case numbers would come down by now, three weeks into Melbourne and the Mitchell Shire's six week lockdown.
"The virus is deeply embedded within the community in Victoria," Dr Coatsworth told Nine's Today program.
"We know that Victorians in those lockdown zones are mixing far less, the movement data shows us we're about where we were in that first wave when the curve started to flatten.

"The other bit of silver lining is that those numbers, whilst deeply concerning, are bouncing between about 350 and 450 a day and certainly we're not seeing doubling during the week, which has to be a good thing."
