Of the new cases, three are from hotel quarantine, nine are from known or contained outbreaks, 19 are from routine testing and 42 are under investigation.

Mr Andrews said there were more than 20,000 tests carried out yesterday.

It comes as Hume City Mayor Carly Moore revealed she was “devastated” and “wanted to cry” after the Premier announced several Victorian suburbs, including many in her council area, are being locked down at 11.59pm tonight.

She said it “doesn’t really make sense” that some parts of a suburb are locked down and others aren’t.
