An emerging cluster has prompted fears the average will go back up above five on Monday. As a result, Andrews delayed announcing any new easing of restrictions for Melbourne and is instead expected to provide an update on the lockdown conditions on Tuesday.
"We had hoped today to be able to announce that metropolitan Melbourne would take significant steps, not from today but from mid week, around retail, hospitality and a whole range of other, important next steps," Andrews said on Sunday.
However, he said the city was "not in a position" to proceed with those plans because there were "at least 1000 test results from that northern metropolitan outbreak that are in the labs".
It comes as Victoria recorded seven new Covid-19 cases on Sunday, with no new deaths.
