Of the locally-acquired cases, 49 are linked to known outbreaks and 25 have been in isolation for the entirety of their infectious period.
The state recorded two additional cases, in hotel quarantine.
Health authorities said full case, testing and vaccination numbers are being verified and will be available shortly.
The numbers come as residents across Melbourne turn out for testing.
Large numbers of people are turning out at a COVID-19 pop-up clinic in St Kilda this morning.
Crowds had been lining up ahead of opening, waiting for their turn to be tested after a number of mystery cases put the area of high alert.
The clinic, next to the Palais Theatre and Luna Park, saw a huge turnout yesterday as the community answered the call to come forward.
It comes as Victoria recorded 57 new local infections on Thursday, up from 24 the previous day.
Yesterday also marked Melbourne's 200th day in lockdown.
