Western Australia has recorded five new local cases of COVID-19 overnight, including another case who contracted the virus from an unknown source.
This afternoon, the Department of Health confirmed four of the five were contacts of previous cases, half of whom have potentially been infectious within the community.
But the fifth case has not yet been linked to any known cases and has been in the community for the duration of their infectious period.
Contact tracers are now working to determine potential exposure sites.
Meanwhile, Wattle Grove Motel, Subway Merredin, BGC Fibe Warehouse in Canningvale, a truckstop in Balladonia and two locations in Belmont Forum Shopping Centre have been added to the growing list of potential exposure sites.
A further five cases were recorded among returned travellers.
The mystery case is the second to be recorded within the past two days, with confirmation just yesterday that a man in his 60s tested positive while presenting in a Perth hospital.
Health Minister Amber-Jade Sanderson told reporters yesterday health authorities were still working to determine how the man contracted the virus, but believed he may be linked to the Cockburn cluster.
The incident forced 12 healthcare staff into quarantine, all of whom were considered close contacts of the case.
Overnight, the US and the European Union upgraded travel restrictions for Australia as a result of the surge in Omicron cases.
