South Australia has recorded a second consecutive day without any new confirmed cases of COVID-19.

33 cases of the virus are now confirmed to have been linked to the Parafield cluster.

Around 4,200 tests were undertaken in South Australia on Sunday, however, health authorities are expecting higher numbers today.

SA remains on high alert, however, as health authorities revealed on Sunday that a man had mistakenly breached quarantine to visit several sites around Adelaide.

SA Health have since issued alerts for a list of locations around the city, from Norwood to Glenelg. You can find the full list of at-risk locations and times here.

In response, pop-up testing stations were set-up at the Brickworks and Kurralta Park locations.
