Victoria has recorded a total of 11 new locally acquired COVID-19 cases, all of them linked to previously reported cases although they were not in quarantine while infectious.

Premier Daniel Andrews says families isolating on the 17th floor of the tower at 130 Racecourse Road in Flemington have all been tested.

"All returned a negative test result so that's very pleasing," he told reporters on Sunday.

"It doesn't mean we are out of the woods there, doesn't mean we can change the settings, but better to have negative results than positive."

Chief Health Officer Brett Sutton said 17 immediate family members had been cleared as well as an additional 200 residents throughout the complex.

The tower was identified as a tier two location between August 3 and 6. COVID-19 Commander Jeroen Weimar said on Saturday eight cases were found in a single family within the building, who were in quarantine.

Victoria will also have 50 state vaccination clinics open from Monday, with nine of them offering AstraZeneca vaccine to 18- to 39-year-olds.

"There are many appointments available, go online," Mr Andrews said on Sunday.

With the best part of 200,000 vaccinations on hand, anyone within the age group willing to provide informed consent would be able to receive a first dose and a second 12 weeks later.

Echoing the premier encouragement, Prof Sutton said: "I'm a 52-year-old bloke. If I were 25 and AstraZeneca was the only vaccine available to me today, I would get it."

Victoria administered 17,360 vaccine doses in the 24 hours to Saturday evening and conducted 38,179 tests.

With 29 cases recorded on Saturday, there was concern Victoria would be forced to extend its current week-long lockdown beyond Thursday.

However, Mr Andrews has so far indicated it is too soon to say.

Meanwhile, Victoria can expect the first of an "additional" 150,000 doses of Pfizer vaccine promised by the federal government on Thursday
