Effectively immediately, hospitality venues across the state will be able to revert to the one person per two square metres measure which were available to South Australians prior to mid November.
However, people will still need to remain seated until restrictions are further reviewed.
The change comes as the state records its sixth day straight of no new COVID-19 cases.
"At the end of the third week of the Parafield cluster, South Australians can be pleased with what they have achieved," Health Minister Stephen Wade shared on Friday.
The new advice from the state's transition committee, which met this morning, outlined that both "economic and social factors" were taken into consideration for the change.
According to SA Police commissioner Grant Stevens, the best course of action was to move to a distancing requirement of one person for two square metres in hospitality.
"Other activities are still restricted to one person per four square metres," he said.

"...all other restrictions in place will remain and be re-assessed during the course of next week, but we are still hopeful that those other restrictions will be lifted and go back to where we were in mid-November on the 14th of December."
Yet added, we are "not out of the woods entirely", in relation to the Parafield cluster.
To date 275 people remain in home quarantine which at the height of the cluster response was between 4000-5000.
Seven cases of coronavirus exist.
The new QR code readers, referred to state authorities as a "game changer in terms of contract tracing, have currently hit 1.1 million check-ins across SA.
"The take-up of QR codes has given us some confidence to manage the risk around this current response to the Parafield cluster...." Commission Stevens said.
"We are in a much better place than we were a week ago."
"QR codes are mandatory for certain businesses and we will be expanding that list, probably in the coming week," he added.
Meanwhile, SA Chief Public Health Officer, SA Health,Professor Nicola Spurrier said that 3548 tests were made on Thursday from a total of 747,388.
"..not high enough, we'd still like to see more," she urged.
