Victorian health authorities have sent out 1700 text messages to people who arrived in the state from Perth on Sunday.
It comes after a security guard working in Western Australia’s hotel quarantine program tested positive for coronavirus, triggering a five-day lockdown across the Perth, Peel and South-West regions.
In a statement the Department of Health said the 1700 text messages were sent to people who had arrived in Victoria from WA with a Green Permit between 25 January and 31 January and came from an area now designated a red zone.
They were advised to get tested and stay isolated until they received a negative test result.
The Perth metropolitan area, the Peel region and the South West region of WA moved from a green zone to a red at 9pm on Sunday night.
This time aligned with the WA government’s stay at home orders for residents in those three regions.
“The Department of Health is continuing to monitor situation in Western Australia,” a DHHS statement read on Monday afternoon.
“A number of WA regions have entered lockdown after WA recorded a positive case of coronavirus. Domestic travel restrictions now apply under Victoria’s ‘traffic light’ travel permit system.
“If you have been in one of these currently listed WA red zones since 25 January, you will not be allowed to enter Victoria without an exception, exemption or permitted worker permit.
“The rest of Western Australia outside of the red zone areas of the Perth metropolitan area, the Peel region and the South West region remain green zones.”
Western Australia recorded zero new infections on Monday.
