All Aboriginal and Torres Strait Islander adults and anyone aged 50 years and over can now book in to get their COVID-19 vaccination.
Phase 2a of the vaccine rollout began on Monday, May 3, with government clinics administering AstraZeneca jabs to more groups of people.
Along with Aboriginal and Torres Strait Islander adults and anyone over 50 years, any critical and high risk workers who have not been able to access the vaccine through earlier phases can now do so.
The government clinics able to provide the vaccine include the Women's and Children's Hospital and the Wayville Showgrounds, both in Adelaide, while two more will open soon at Noarlunga and Elizabeth.
These clinics are open ahead of general practices being able to provide vaccines from Monday, May 17.
Minister for Health and Wellbeing Stephen Wade said the National Cabinet had decided to fast-track phase 2a of the rollout.
"The level of vaccination in South Australia continues to be above our share of the population and opening more clinics across the state will help us continue our safe, steady scale up of the vaccine rollout," he said.
"Those eligible can identify upcoming clinics in their region online and schedule an appointment online.
"We look forward to high levels of interest and ask people to be patient should they not be able to secure their appointment at the time they are hoping for."
