Four people with COVID-19 have died in South Australia — two women in their 90s, a man in his 70s and a man in his 80s.
SA Health reported 3,733 new cases today, a drop from 4,856 yesterday.
The number is also down on Thursday last week, when 4,079 were recorded.
Testing numbers were also down over the past three days and over the Anzac Day long weekend compared with the previous week.
A total of 240 people with COVID-19 are in hospital, including 11 in intensive care.
There are currently 25,246 known active cases in South Australia, the lowest number since March 20.
From Saturday, close contacts of COVID-19 cases in South Australia will no longer have to quarantine, bringing the state into line with interstate rules.
The new rules announced last week will reduce the quarantine time from seven days to none, although there are still strict rules to follow.
SA Opposition Leader David Speirs this afternoon revealed he had tested positive for COVID-19.
He said he had a "scratchy throat" but otherwise felt healthy, and would work from home as he isolated for seven days.
"After developing minor COVID-19 symptoms I did a rapid antigen test which returned a positive test this afternoon," he said.
"I am in the process of communicating with everyone who I have met with over the past two days and encouraging them to get tested where appropriate."
