South Australia's first regional collection site for COVID-19 rapid antigen tests has been opened in the state's Riverland.
The new site is in the old Glossop High School and the state government says more sites will open in coming days, including those at Port Augusta and Murray Bridge on Tuesday.
The government began issuing the tests for close contacts last week, but initially from only one site in Adelaide.
"Providing even greater and easier access to RATS is an important part of our ongoing plan in response to the Omicron outbreak," Premier Steven Marshall said.
"The Omicron variant was a game-changer but South Australia's plan has been both strong and adaptable to mitigate the health and economic threats as we open up and protect local jobs during this challenging period."
The government is providing two rapid tests to each close contact of a confirmed virus case.
They are to be taken on days one and six of the seven-day isolation period.
It's hoped their widespread use will give authorities a clearer picture of how many virus infections are in the community, with the reporting of positive results mandatory.
Any close contacts who don't have immediate access to a RAT can still opt to have a PCR swab.
On Sunday, SA reported a dip in new coronavirus infections to 3450, taking the total number of active cases to 33,921.
Recent modelling suggested the current outbreak will reach its peak by January 25, when up to 10,000 daily cases could be expected.
But Sunday's fall, from 4349 on Saturday, prompted suggestions the peak may have already been hit.
