On Friday, hundreds gathered outside Parliament House amid chants of “we will not comply” and “Aussie, Aussie, Aussie, oi, oi, oi”.

Mr Cook called the threats to the Premier “just despicable – disgusting”.

“We have to understand that the only way we can protect Western Australia is by getting high vaccination rates,” he said.

“I just urge people to stop this ridiculous behaviour and simply accept the science.

“Understand that the way that you are meant to protect you, protect your family, and the way that you protect the community is by giving back to the community.”

He said he expected to get to around 80 per cent vaccination for 16s and over by mid-December but they would provide more solid predictions for opening up once they had stronger vaccination numbers by Christmas.

The vaccination mandates are split into three groups, with people working in situations where transmission of the virus is high or could impact vulnerable communities required to have received their first dose by December 1 and second dose by December 31.

The second group are deemed to be jobs critical for the function of businesses and the community and includes childcare and school workers, including all teachers.

This group must have received their first vaccination dose by December 31 and must be fully vaccinated by January 31.

The third mandate applies only if a lockdown, where people working in jobs such as bottle shops, media, pet stores, and members of Parliament, are required to show proof they are fully vaccinated to their employer if they want to attend work.
