A snap Covid lockdown for Victoria will reportedly be announced later today, sources have claimed.
The Herald Sun and ABC reports that the final details of the state's fifth lockdown are currently being worked out behind the scenes.
An announcement is expected to be made by Premier Daniel Andrews on Thursday afternoon.
Health department sources say the lockdown will be similar to previous others and will begin at midnight on Thursday.
It is unclear what the exact restrictions may be, but it is likely they will involve limited reasons to leave home and could last up to five days, the publications report.
On Thursday, Covid-19 Commander Jeroen Weimar confirmed the two new cases were in addition to 10 locally acquired infections recorded in the previous 24 hours, all of which were previously reported.
The two cases - an adult and a child - appear to be linked to a Maribyrnong man, who attended an AFL match between Carlton and Geelong at the MCG on Saturday and sat in the MCC member's reserve on level 2.
But Mr Weimar said the duo were not known contacts of the infected man and it appeared to be a case of "stranger-to-stranger transmission".
"They were sitting in very different parts of the ground. There's no obvious relationship between them. The interviews and discussions are ongoing," Mr Weimar said during a media conference.
The infected man, aged in his 60s, attended the game with his friend, a teacher from Bacchus Marsh Grammar school who lives in Barwon Heads.
The teacher and two of his family members, a nine-year-old child and a man in his 60s, have also subsequently tested positive for COVID-19.
Both Bacchus Marsh Grammar and Barwon Heads Primary School have been closed and more than 3500 students and staff are self-isolating.
Mr Weimar warned residents that the latest Covid outbreak is "moving quickly".
"We're dealing with a very dynamic situation here, a very rapidly moving situation," he said.
"What we've got is two separate incursions into Victoria over the last three or four days, two chains of transmission, at least one is moving very actively and very aggressively across the state."
