Melbourne will go into its fourth COVID-19 lockdown after the latest virus cluster in the north of the city continues to grow.
Acting Premier James Merlino announced a seven-day circuit breaker lockdown on Thursday morning.
Earlier, Victoria’s Department of Health confirmed 12 new COVID-19 cases were recorded overnight.
While Victorian authorities have “run down multiple generations of transmission“, Chief Health Officer Brett Sutton has been concerned about the amount of time some of the positive cases have been out in the community.
“We’ve got significant spread of exposure sites at the moment so it’s not something that we would look to at a postcode level,” he said on Wednesday.
As of Thursday morning, there were 79 exposure sites listed on the Health Department’s website, spread across more than 30 Melbourne suburbs and regional Bendigo, Cohuna and Red Hill.
The MCG and Marvel Stadium are amongst the exposure sites and three inner- suburban nightclubs remain a “concern”.
An infected person attended the Collingwood-Port Adelaide AFL game at the MCG on Sunday, while one was also at the North Melbourne-Essendon clash at Marvel Stadium later that same day.
A number of restrictions were introduced for Greater Melbourne on Tuesday evening, including gathering limits of five people at homes and 30 in public and mandatory masks indoors.
Genomic sequencing shows the City of Whittlesea outbreak is linked to the case of a Wollert man, who contracted the virus in quarantine in South Australia earlier this month.
