Victoria has recorded no new COVID-19 cases after an infected local returned home from Perth last week sending parts of WA into a snap lockdown.
More than 10,000 Victorians with links to Western Australia's coronavirus outbreak have been told to isolate, as neither state recorded new COVID-19 cases today.
Victoria declared the Perth and Peel areas red zones, meaning anyone from those areas must be tested and isolate for 14 days.
The harsh measures come after a Victorian man visiting Perth tested positive to coronavirus last week.

So far 42 people have landed in Victoria after visiting exposure sites in Perth, all of whom are currently isolating; 32 have tested negative.

The Perth and Peel areas entered a snap lockdown set to lift from Tuesday.
WA Premier Mark McGowan said if it was not safe to open up, restrictions would remain in place.
"We just have to be cautious," he said.
"We're not going to make a move which will elevate the risk to the Western Australia public, our number one priority is to keep West Australians safe.
"So we won't be opening up if we think there's any potential for further outbreak."
