The new infections were revealed a day after Premier Steven Marshall announced restrictions would be eased on December 28.

For those who are fully vaccinated, dancing and standing while drinking will be permitted.

Caps on home gatherings will be removed and Covid management events will increase from 1000 to 3000.

Venues such as cinemas and theatres, can go back to 100 per cent capacity for the fully vaccinated, with the exception of nightclubs and indoor gyms which will be allowed to operate with a one person per two square metres density requirement.

It was also revealed quarantine for double dosed overseas arrivals would be reduced from seven days to just 72 hours from December 28.

“I know this will be a huge relief to many people who have been looking for that (restrictions to ease),” Mr Marshall said.

“We're convinced we need to keep the mask mandate in place for all indoor areas at the moment.

“We'll continue to look at it but we know that this (Omicron) is a highly transmissible variant and we know this is a way of protecting ourselves as we gather more information.”
