Western Australia Premier Mark McGowan has announced the state's hard Border will remain in place in response to the threat of the Omicron variant.

The state was due to re-open on February 5.

Whilst the hard border controls will remain, there will be more exemptions, especially for compassionate cases.

"In light of what has occurred in the rest of the country, having closely assessed the situation over east, and listening to the latest health advice, we have reworked WA's safe transition plan to fit the environment that now confronts us," Mr McMcGowan said.

Who will be allowed to enter WA?

From 12.01am on Saturday, February 5, the hard border will stay, but with some new settings.

Returning Western Australians with strong recent connections or direct legitimate family connections with WA should be granted exemptions.

Compassionate grounds to Travel to the state include: attending funerals, palliative care or terminally ill visitation, people entering for urgent and essential medical treatment, people entering for reasons of national and state security, and people with specialist skills not available in WA.

Commonwealth and state officials, members of parliament, diplomats and people with court proceedings will be allowed to enter.

Other special considerations will be given to extraordinary circumstances, as determined by the state emergency coordinator or Chief Health Officer.

What are the requirements once you enter WA?

Approved travellers from interstate will need to be an approved G2G pass traveller, have received a booster — if eligible — and return a negative pre-departure rapid antigen test 24 hours prior to departure (by uploading the result as part of the G2G pass application).

Those arrivals will need to undertake 14 days of self-quarantine at a suitable premise.

Mr McGowan said household members must also self-quarantine for the same duration and follow the same requirements, if sharing the same space..

"You also need to have PCR testing within 48 hours of arrival and on day 12 of self-quarantine," he said.

"Everyone at the self-quarantine premise is subject to mandatory use of G2G now and in-person checks will be undertaken by West Australian Police as and when required."

When will the border reopen now?

No new date has been announced for the border to reopen.

Mr McGowan said WA's booster shot rate currently sat at 25.8 per cent.

He said he was aiming to get that number as high as 80 or 90 per cent but stressed his government would be watching what happened "over east" throughout February.

He was hoping 35-38 per cent of the eligible population would have received a booster by February 5 but admitted the higher numbers would take "some time" to reach.
