COVID-19 cases in WA have more than doubled to 643 new local infections up from 258 the previous day.
Two more people are also in hospital with COVID taking the total number to five.
None are in intensive care.
There are now 1787 active cases across the State.
It comes as WA Health released modelling on Tuesday that predicts almost half a million West Australians will contract COVID by August.
Of those, 5685 people will be hospitilised and 715 will be ICU admissions, while 129 people will die from the virus in the next six months.
The Omicron outbreak is predicted to peak in late March where 10,300 new cases will be recorded each day in WA.
