'Covid is everywhere': Cases triple in Victoria
The grim reality of Victoria's Covid-19 situation has been laid bare, with officials warning cases have tripled in some areas in the past week.
Victoria's Covid response deputy secretary, Kate Matson, warned the virus was now "everywhere" in Melbourne.
"Covid is around everywhere in Metropolitan Melbourne. Please do act as if it's, you know, at the supermarket when you go – keep your mask on and practice your Covid-safe behaviours," she said.
Of today's 1763 new cases, 681 were discovered in Melbourne's northern suburbs and 514 were discovered in the western suburbs.
"Across all different local government areas, but 111 in Wyndham, 105 in Melton, 103 in Brimbank. Concerningly, this rate has doubled over the past seven days," Matson said.
"57 in Moonee Valley. 48 in Maribyrnong. And 35 in Hobsons Bay. Cases are continuing to grow in the southeastern suburbs, making up 21% of today, or 370 new cases, including 131 in Casey. This rate has tripled and is showing the largest growth in Melbourne."
Treasurer Frydenberg in isolation over Covid case
Australian Treasurer and Deputy Leader of the Liberal Party Josh Frydenberg is in isolation after a member of his staff tested positive for Covid-19.
In a statement, Frydenberg said the staff member hasn't yet been contacted by Victorian contact tracers, so he does not know if his electorate office will be deemed an exposure site.
However, "out of an abundance of caution", the electorate office has been closed for deep cleaning, Frydenberg has returned a negative Covid test result and will be isolating until further notice.
