Melbourne-based epidemiologist Professor Tony Blakely says Thursday's increase in cases in Victoria is worrying.
"If this does go up, with 1500 cases and increasing, we're going to have to do a lot more to slow it down," he said.
Blakely told 1News that Victoria's officials should be looking at whether they needed to enter a lockdown similar to New Zealand's Level 4 restrictions.
"We don't want to crash through 2500 because at that point. you're going to put a lot of stress on health services."
Today's caseload of 1438 infections is a new record for Victoria.
