South Australia has recorded two new local cases of Covid-19 and one infection in hotel quarantine.
Premier Steven Marshall said all were in strict quarantine and do not pose a threat to the community.
His said the state is on track to lift the lockdown on Tuesday night.
SA also achieved a record number of tests with more than 23,000 people getting swabbed in the latest reporting period.
“It is very clear to me that South Australians are taking this lockdown order very, very seriously,” he said.
“We do not want a prolonged lockdown in South Australia. We want to come out Tuesday. And the actions of all South Australians are speaking volumes.”
Mr Marshall described Monday as “D-day” and said he doesn’t want to see any more cases “especially outside the community”.
“This has been one of the reasons why we believe we are 100 per cent right to act very decisively when this cluster first appeared,” he told reporters.
Authorities were looking at a range of scenarios in terms what the steps out of lockdown might look like with a focus in getting kids back in classrooms and people back to work
But one rule he won’t budge on is the one limiting gatherings at hospitality venues to one person per four metres, given the escalating situation in NSW.
“The situation over in NSW will have an effect on the restrictions right across (SA),”Mr Marshall said.
“I don’t want to preempt (rule changes) at the moment.”
Three international flights that were due to arrive in Adelaide on Monday and Tuesday have been cancelled after the Premier asked Prime Minister Scott Morrison to postpone them.
Mr Marshall on Saturday said the request came from SA Pathology clinical service director Dr Tom Dodd because authorities were “very concerned” and wanted to avoid running out of capacity with the high level of testing that’s underway.
The state has the capacity to complete 18,000 tests within SA Pathology per day as well as more through the two other private labs.
“We are in a lockdown and we don’t know what is going to happen on Monday or Tuesday so we’re asking the Commonwealth to back us,” Mr Marshall said.
