WA has recorded no new local community cases of COVID-19 in the past 24 hours.
There are four new cases in hotel quarantine, all returned travellers from India.
The Perth and Peel regions emerged from lockdown at midnight, but interim restrictions remain in place.
Interim restrictions remain in place until 12.01am on Saturday.
Masks must be worn, with indoor and outdoor gatherings restricted to 20 people.
Two locally acquired infections were found from more than 29,000 tests after the virus leaked out of the Mercure quarantine hotel.
WA’s health department was aware of ventilation issues at the Mercure but had believed the risk could be mitigated.
The outbreak has renewed hotel quarantine concerns and prompted calls for the federal government to invest in purpose-built facilities.
Premier Mark McGowan has urged the Commonwealth to open air bases and Christmas Island to accommodate returned travellers.
