Western Australia has recorded another 4,300 COVID-19 cases, with 103 people in hospital.
WA Health Minister Amber-Jade Sanderson said five people were in ICU on Friday night, but three had since been released.
Of the positive cases, 2,339 were detected with PCR tests and 1,961 were the result of self-reported positive RATs.
The number of active cases in the state has risen to 22,757.
Cases tracking close to forecasted peak: Health Minister
Ms Sanderson said the state was still on track to reach its peak in cases in the next week.
"I think we're tracking pretty close to the forecasted peak to be sometime next week," she said.
"It might be a little later, but certainly from that sort of March 14 day we will expect that peak to start tracking upwards and getting there, yes."
She said the total peak number was still expected to be about 10,000 cases a day, in line with modelling.
"Although having said that, our cumulative cases are higher by quite a few thousand … so that's an interesting outcome, we have higher cumulative cases but tracking the same in hospitalisations," Ms Sanderson said.
"I think that is testament to the vaccination rates and people really doing the right thing around the public health and social measures and adhering to those rules.
"We won't see hospitalisations peak for a week to nine days after cases peak, so it won't be until towards the end of March that we really see that steep rise in cases in hospital."
WA won't adopt new national isolation rules
Ms Sanderson said WA would not adopt the relaxation of isolation rules for close contacts agreed upon at the National Cabinet meeting on Friday.
"Western Australia is experiencing its first wave, whereas in the eastern states, certainly New South Wales and Victoria, they are experiencing or finishing their fourth wave, so we are in a very different place," Ms Sanderson said.
"National Cabinet recognises and acknowledges that — so we won't be adopting that position at this point.
"We obviously all want to get there at some point in the future, but we are early in the outbreak at the moment and are dealing with that.
"To be very clear with the community, there is still a requirement for PCR testing and rapid antigen testing, and close contacts in WA are still required to isolate."
Ms Sanderson said the intention was to keep the higher restrictions in place for as little time as possible.
"The plan developed in line with the modelling was to have the higher restrictions in place for four weeks, taking us to the end of March before we can lift it," she said.
"We are tracking according to the modelling so far, which is good, but we are only at the beginning of even getting to our peak."
Community responds to free RATs program
Ms Sanderson said it was positive to see the community making the most of the government's free RATs program.
"From the last figures I was given, more than 720,000 households have registered, and about 300,000 have either received or gone to collect the Rapid Antigen Tests," she said.
Ms Sanderson said the government had a good stockpile of the tests and was working to get them out into regional areas.
