SA to ease restrictions from December 28 as 64 new COVID-19 cases recorded

Further COVID-19 restrictions are being lifted in South Australia from December 28.

Premier Steven Marshall said he believes the state will reach 90 per cent fully vaccinated by that date.

Fully vaccinated people will be allowed to stand up for drinks in pubs and dance, but the 75 per cent density requirement will remain in place.

For fully seated venues, however, that density requirement increases to 100 per cent, including at cinemas, restaurants and theatres.

It comes as the state recorded 64 new cases of COVID-19 overnight.

Quarantine time for international arrivals in South Australia is also set to be reduced to 72 hours from December 28.

Unvaccinated arrivals will still be required to quarantine for 14 days.

Travellers will also need to take a PCR test within 72 hours of arriving.

"We need to put these speed bumps in the wake of Omicron coming into South Australia [as] our borders have been open," Mr Marshall said.

Mr Marshall said he is not troubled by current COVID-19 hospital numbers.

"Our key metric is looking at hospitalisation and to date, we've had three admissions in three and a half weeks," he said.

"This doesn't trouble us at all because we've been ahead of the game."

He acknowledged COVID-19 numbers are likely to keep climbing, but people shouldn't be overly concerned about that.

"What we will be doing is constantly keeping you updated about hospital admissions," he said.
