West Australians aged 30 to 49 will be eligible to receive the Pfizer coronavirus vaccine from Thursday, Premier Mark McGowan has announced.
Bookings are now open for over-30s at state-run clinics including Claremont Showgrounds which will offer Pfizer jabs seven days a week.
It comes after national cabinet last week agreed to expand the vaccine rollout to people aged 40 and over.
"Here in WA, we're going one step further," Mr McGowan told reporters on Tuesday.
The rollout will also be expanded to include Aboriginal and Torres Strait Islander people aged 16 and over.
People aged 50 and over will continue to receive the AstraZeneca vaccine.
The premier said capacity at state-run clinics in Claremont, Joondalup, Kwinana, Redcliffe and Bunbury would vary from 700 to 2000 appointments per day.
He called on the Commonwealth to ramp up supplies of the AstraZeneca vaccine to GPs and for pharmacists to be allowed to administer jabs.
Health Minister Roger Cook said WA had about 150,000 vaccine doses in stock, including more than 107,000 Pfizer doses.
A further 1.2 million doses are expected to arrive in the next six weeks.
"This is a significant day for WA," he said.
"What we are announcing today is a huge expansion of our vaccination program."
