Victoria has recorded 473 new locally-acquired cases of COVID-19, the highest single-day tally of the outbreak so far.
Of the new cases, 202 have so far been linked to known outbreaks.
There were 49,037 test results received yesterday, and 30,032 doses of vaccine were administered at state-run sites.
Four Melbourne childcare centres were listed as tier 1 exposure sites overnight, bringing the number of venues to nearly 1,100.
The latest figures show at least 66.2 per cent of the eligible 16+ population has had one dose of a vaccine, and 40.8 per cent are fully vaccinated.
More disruption to regional train services
V/Line passengers are again dealing with major disruptions to train services after hundreds of workers forced into isolation.
Five drivers and staff have now tested positive to COVID-19, forcing V/Line to furlough 300 workers, up from 180 a day earlier.
V/Line will operate a limited number of morning services on the Ballarat and Bendigo lines, and a full service on the Seymour line, but there are major changes elsewhere.
Customers have been told they should allow an extra 90 minutes for their journey.
Department of Transport spokesman Chris Miller said coaches would continue to replace most V/Line services today.
“We really do apologise for this disruption. It is inconvenient for everyone right across the state. We are working as hard as we can to minimise that,” he said.
“Unfortunately, this is an evolving situation, we are taking it day by day. We are doing our very best to minimize disruption to out passengers and we thank them for their patients as we get through this difficult time.”
