Victoria has recorded another 165 new cases of coronavirus, as nearly five million people around Melbourne begin their first day back in Stage 3 lockdown.
It's the fourth day of new cases in the triple-digits, with the state's overall total now 3098.
Of the new cases announced on Thursday, 30 are linked to known outbreaks and 135 are under investigation. No cases have been detected in returned travellers in hotel quarantine.
There are 18 new cases linked to the North Melbourne and Flemington public housing towers, with 111 there in total. Testing concluded at the estates on Wednesday night.
Residents there have been in a hard lockdown since Saturday afternoon, unable to leave their apartments due to fears the high-density "vertical cruise ships" have "explosive potential" to spread COVID-19.
Six of the new cases are linked to an outbreak at Al-Taqwa College in Truganina, which has become the state's biggest cluster totalling 113 people.
Two healthcare workers at Sunshine Hospital and two at the Royal Melbourne Hospital have also tested positive, with contact tracing underway.
Seven new cases are staff members at aged care facilities across Melbourne.
Premier Daniel Andrews is expected to face the media later on Thursday.
