Western Australia faces months of COVID-19 restrictions ahead as other states unwind mask-wearing and density limits.
WA Health is managing 1315 active cases after the state on Tuesday recorded 258 new local cases and five travel-related infections.
Three people are in hospital in general wards.
While WA prepares to reopen its borders on March 3, the state's Omicron outbreak is not expected to peak for at least another month.
The McGowan government's modelling suggests WA's caseload will peak at the end of March at around 10,000 daily infections, four deaths a day and almost 500 people in hospital.
New restrictions came into effect this week, including density limits at hospitality venues and a state-wide requirement to wear face masks at public indoor venues.
They are on top of existing proof of vaccination rules which apply to virtually all hospitality venues, cultural venues, stadiums and gyms.
Premier Mark McGowan on Tuesday declined to give an exact time frame for how long the rules would remain.
There is also no guidance on when tougher "level two" restrictions, including stricter density limits and a requirement for students in year three and above to wear face masks, might be triggered.
"Obviously we'll try and be brief as possible. But there will be some ongoing restrictions for, I expect, some months to come," he told reporters.
Victoria, NSW and Queensland have all outlined plans to relax rules around face masks and density limits in coming weeks as they move past the peak of their outbreaks.
Mr McGowan said WA's circumstances were "completely different", having had barely any community spread of the virus and few non-travel restrictions prior to its Omicron wave.
"The other states still have various restrictions in place over this period," he said.
"We have had two years virtually pain-free whilst the eastern states have been through a shocking experience.
"That's the price we pay for getting very, very high levels of vaccination before we get widespread spread of the virus."
About 58 per cent of eligible West Australians have received their third vaccine dose.
Opposition Leader Mia Davies questioned the need for ongoing proof of vaccination at hospitality venues.
"Clearly, with a very high vaccination rate here in Western Australia - 98 per cent (first) dosed - it is absolutely the time to look at whether or not all the mandates we have in place are proportionate and reasonable," she said.
An outbreak in the remote Aboriginal community of Mantamaru, also known as Jameson, has grown to four cases after another two people tested positive.
The community, about 1000km east of Kalgoorlie and home to about 50 people, is now in lockdown.
Education Minister Sue Ellery said 77 schools had active cases, with hundreds of students and teachers forced to isolate since the start of the term.
"It's certainly been a bumpy start and it has been disruptive but schools have adjusted," she said.
