South Australia to drop state border controls next month

South Australia's state borders are coming down in less than a month, Premier Steven Marshall has revealed.

Mr Marshall said November 23 would mark the start of South Australia's roadmap out of COVID-19 restrictions.

State border controls will be removed for fully vaccinated travellers, while quarantine for fully vaccinated overseas arrivals will be halved to seven days.

Unvaccinated arrivals will still need to quarantine for 14 days.

The cap on home gatherings from 20 to 30, but other restrictions will remain in place.

Masks will still be necessary for indoor gatherings, and private activities will have a cap of 150 people.

Current density and crowd limit requirements will be unchanged.

Mr Marshall said November 23 was when South Australia was forecast to hit 80 per cent full vaccination levels.

"The race is on in South Australia," he said.

"We need to get as many people vaccinated as quickly as possible."

Mr Marshall forecast the 90 per cent vaccination level could be reached by the end of the year.

At that point, he said, quarantine requirements for vaccinated overseas arrivals would be discarded.

The "vast majority" of remaining restrictions in South Australia would also be lifted then, though Mr Marshall said some safety measures, particularly around events, will remain in place.

"High-risk" activities, including going to nightclubs and drinking while standing up in licensed establishments, will be restricted to the fully vaccinated.

Masks will also still be required in places including hospitals and aged care centres.

COVID-19 patients and their close contacts will still need to isolate.

Vaccination lagging in some areas

Mr Marshall said the government was focused on achieving vaccination equity.

"There are some that are lagging behind. There's some reasons for that," Mr Marshall said.

"We're redoubling our efforts in all of those areas.

"We want to see equity right across the system in South Australia, but we also want there to be a fairness for those people who have done the right thing."

Mr Marshall said the government is still waiting on the final Doherty Institute modelling about "public health (and) social measures" for the 90 per cent vaccination target.

He said the state was preparing for an escalation in COVID-19 cases that would come with increased openness, with a $123 million package unveiled this week.

This would include new beds in hospitals and increased staffing levels.

Mr Marshall said all 1200 graduating nurses in South Australia this year had been hired by the public health system.
