South Australia has recorded 1,118 new cases of COVID-19 and no further deaths.
SA Health said there were 190 people in hospital — eight more than yesterday — including 13 in intensive care and four requiring a ventilator.
The state now has 13,189 active cases.
Premier Steven Marshall said today's case numbers had given authorities "great confidence" to be able to further reduce restrictions at the end of this week.
"We've opened up a lot during this week with school students going back to school, with 50 per cent of people in offices, increasing the cap for home gatherings and getting 75 per cent density and stand-up consumption in our hospitality, and yet we've seen the number of positive cases track down," he said.
Meanwhile, the Myer Centre COVID-19 vaccination clinic in Adelaide's CBD will become a dedicated Novavax hub this week.
Novavax, Australia's first protein-based COVID vaccine, was added to the national vaccination program last week for first and second doses for people aged 18 and over.
The Myer Centre clinic will be closed on Monday and Tuesday and re-open for Novavax appointments for adults from Wednesday.
