South Australia has dropped its local COVID-19 restrictions put in place about a week ago in response to growing virus numbers in other states.
Premier Steven Marshall says the measures will be removed immediately.
The change returns SA to a general density rule of three people to every four square metres.
Public gatherings can increase from 150 to 200 people and drinking while standing up and dancing can also return.
Mr Marshall says the increased restrictions were necessary, given the situation SA faced with some local cases and increasing infections in other jurisdictions.
"We weren't wanting to take any chances with the escalating numbers right across the country," the premier said.
"But we think people will be very pleased with this.
"We said we didn't want to keep the restrictions in place for any longer than necessary."
At the same time, SA will also lift its testing requirements for travellers from Victoria but will keep hard border closures in place for Western Australia, Queensland, NSW, the ACT and the Northern Territory.
The state's transition committee will meet again on Thursday to consider easing those rules, particularly in relation to WA, Queensland and the NT.
Also on Monday, the state government opened a new mass vaccination clinic at Victor Harbor, south of Adelaide.
The first of three clinics to open this month, Health Minister Stephen Wade said the vaccine program was "our doorway out of the pandemic".
"This clinic will provide up to 700 vaccinations per week - 500 Pfizer and 200 AstraZeneca - providing more opportunities for eligible South Australians to roll up their sleeve and get vaccinated," he said.
"Later this month we will also be adding two more vaccination clinics, with a clinic at Mount Barker set to open on July 12 and in Gawler before the end of July."
