South Australia has recorded four COVID-related deaths along with 4,500 new infections.
Three men — aged in their 70s — and a man in his 80s who tested positive to the virus have passed away.
There are 246 people with the virus in hospital, including 10 people in ICU and two people on a ventilator.
The number of active cases has also risen for the first time in almost a fortnight – to 28,991.
The number of new cases jumped despite a 13 per cent reduction in testing.
SA Health data also shows 93 per cent of today's cases were the Omicron sub-variant BA.2 — up from 60 per cent of samples yesterday.
South Australian authorities have decided to drop close-contact rules from next week.
People will instead need to undertake five at-home tests, tell their employer that they are a close-contact and will not be allowed in high-risk settings.
From today, close contacts in New South Wales and Victoria will not have to isolate if they feel well and test negative to COVID-19 on rapid antigen tests.
