South Australian COVID-19 testing will focus on specific cohorts of the population, as the state's pandemic response moves into suppression phase.

South Australia will become the first state to begin to fully restore elective surgery from midnight tomorrow with the lifting of the Appropriate Surgery Direction under the Emergency Management Declaration.

Supermarkets and other retailers across suburban Adelaide will continue to be permitted to trade extended hours, including 9.00 am Sunday morning starts, to help maintain vital social distancing measures as South Australians embrace easing restrictions.

South Australians are now able to get the result from their COVID-19 test in less than 60 minutes at 17 hospitals across the state.
