WA recorded no new cases of coronavirus in hotel quarantine or in the community today.
Amid the changes to hotel quarantine, the state will relax restrictions for residents of Perth and Peel on Saturday.
WA accepted a maximum of 1025 international arrivals per week prior to the Anzac Day long weekend, but this was temporarily reduced to 512 after hotel quarantine breaches.
Moving forward, Mr McGowan has indicated a permanent reduction in the number of arrivals the state will accept each week.
“We’ve analysed our capacity [for hotel quarantine], we can safely take 530 people,” he said.
“Within our cap, that’s what we can do. We’ll have a look at what we can do within that cap to bring people here from India, and will no doubt work with the Commonwealth Government on that.”
Mr McGowan said it would not be the only change to hotel quarantine.
“We’ve had two very significant incidents in the last couple of weeks involving hotels,” he said.
“We’re taking three hotels offline, we’re reducing the density in other hotels and we’re ensuring we have more space inside those hotels so that takes us down to 530.”
From 12.01am on Saturday, masks will only be required on public transport or at events and venues where more than 1000 people are present.
Masks will also be required in hospitals, disability centres, and aged care homes.
Residents of those facilities will be allowed up to four visitors per day.
From Saturday, residents will be allowed to have up to 100 people in their homes at private gatherings.
Nightclubs and casinos will be re-opened, but will be subject to a rule of one patron for every two square metres of floor space.
Football stadiums will re-open but crowds must wear masks while attending a match.
