Austral have been urged to be patient as coronavirus restrictions continue to ease across the country.
Steven Marshall, Premier of South Australia (SA), told reporters on Monday that the state would continue to ease restrictions in a "careful and considered way, not a reckless way", reports Xinhua news agency.
SA on Monday moved into stage two of lifting restrictions with the maximum gathering size increased to 80.
In Victoria, pubs, cafes and restaurants opened their doors to customers for the first time since March.
"We have said from day one in South Australia, it is not just about opening. It is about opening sustainably," Marshall said on Monday.
As of Monday, there were 7,204 confirmed cases of COVID-19 in Australia.
There have been four new cases in Victoria, three in New South Wales (NSW) and two in Western Australia (WA).
Prime Minister Scott Morrison in May announced a three-stage plan to restart Australia's economy in a "COVIDSafe environment" by July.
