A police spokesperson said a number of people were arrested later that day for either breaching the move-on notices or failing to provide identification.

The majority of the West Australian community has now had at least one dose of the vaccine.

Mr McGowan said high vaccination rates reduced, but not entirely removed, the need for density limits and heavier restrictions to eventually be introduced.

“When we bring [density limits] in, we bring them in on health advice, we will not leave them in place for longer than they need to be, ”he said outside Parliament on Thursday.

“Even with high vaccination rates, you still get hospitalization, and you want to make sure that you minimize the peaks of that so that you can minimize the people in ICU and on ventilators.

“We have been incredibly fortunate in Western Australia over the course of the last two years. I want us to continue to be fortunate. ”

A date for borders to reopen has not yet been provided.

Opposition leader Mia Davies said Mr McGowan was “paralyzed by indecision” after requests for the state government to reveal its modeling were knocked back.

“What we have observed is a Premier that is arrogant, is secretive, and is fast losing the trust of the people of Western Australia,” she said.

“We’ve asked multiple questions as an opposition in relation to health modeling. We’ve tried to determine what thresholds the public will need to meet in terms of third vaccinations.

“None of that has been forthcoming. The people of Western Australia deserve more having done everything this Premier and government has asked over the last two years … we’ve got complacency, we’ve got fatigue.

“We have hospitals that are now moving into an amber stage of readiness. They clearly have information and triggers that the rest of the state are not privy to. ”

Staff in all public hospitals in the Perth and Peel region, the Wheatbelt and the Great Southern have moved to amber alert, a higher risk rating, from Thursday.

The amber alert is the second of four stages the health system will use to deal with Omicron cases as they rise, with the move made due to the rising daily case numbers.

A red alert will be used when the community experiences high transmission levels and a black alert will be put in place if the health system reaches capacity.

Australia Medical Association WA president Mark Duncan-Smith said he supported the decision.

“This is a proactive step to protect both healthcare workers and patients … it will reduce the furloughing of workers,” he said.

“In areas considered higher risk, staff will take twice-weekly RATs and more PPE will be provided.”

Dr Duncan-Smith said he hoped WA would follow South Australia’s modeling going forward, which had “reduced their peak in cases five-fold.”
