COVID testing sites

There are more than 40 sites across the state where South Australians can access a PCR with and without a GP referral.

This includes new walk-in clinics at Salisbury and Brighton, Frome Road in Adelaide, and Mount Barker where people can get a free PCR without a referral.

Bookings are preferred.

PCR testing should be prioritised for people who are more vulnerable to the health impacts of a COVID infection and who would benefit from prompt diagnosis and treatment with oral antiviral medications.
