Unvaccinated West Australians will be banned from entering bottleshops or dining at fast-food restaurants as the state prepares to open its borders.
Premier Mark McGowan says the restrictions will come into effect from January 31 ahead of the February 5 border transition.
Proof of double-dose vaccination will be required at all hospitality venues, including restaurants, cafes, pubs, bars and fast-food outlets for dine-in customers.
It will also be needed for visitors to public and private hospitals and aged care facilities, indoor entertainment venues including play centres, casinos and cinemas, gyms and fitness centres, the zoo, Crown casino and amusement parks.
The requirement will apply to anyone aged 16 and above and will be implemented across the state.
"Life will become very difficult for the unvaccinated from January 31," the premier told reporters on Thursday.
"These will be the broadest proof of vaccination requirements in the nation and they will not be removed anytime soon."
Mr McGowan said West Australians who chose to remain unvaccinated were putting themselves and others at risk and increasing the burden on the health system.
WA is set to scrap quarantine for fully-vaccinated arrivals from February 5 but the government is yet to outline how it will define close contacts of positive cases.
The premier said it would largely mirror the rules of other states but declined to provide further details.
Opposition treasury spokesman Steve Thomas said small businesses were desperate for certainty.
"Business and industry are crying out for a coherent plan to be made public but the government seems unable to deliver one," he said.
Two new local infections emerged on Thursday, one linked to the Hyatt hotel cluster and the other a household contact of a previous case.
Authorities are continuing to investigate a woman who contracted the virus from an unknown source.
She was infectious in the community but did not attend work and there appears to be few potential exposure sites, WA Health said.
Genomic sequencing will determine the variant of her infection amid fears WA could have undetected spread of the virus.
The recent surge in cases in the eastern states has fuelled anxiety about how WA schools will function once the borders reopen.
Education staff are required to be double-dose vaccinated by January 31 when the school year begins.
But about seven per cent of staff employed by WA's Department of Education are yet to provide proof of vaccination.
"Since the department began phoning school staff this month about their status, the number who are yet to upload evidence of vaccination has been falling every day," the department's director general Lisa Rodgers said on Thursday.
"There is still about three weeks of school holidays left and we anticipate that employees will use this time to receive their second dose and update their vaccination certificates before school returns.
"We have contingencies in place and more than 5000 vaccinated casual staff in the system who can fill in where there are vacancies."
