On Sunday, official Australian Government data showed 77.2 per cent of the state’s population aged over 16 had received two vaccination doses. Just over 87 per cent of the same population group had received at least one dose.

The State Government announced November 23 as the date for opening the borders, on the basis that it predicted 80 per cent of the population would be vaccinated by then.

However, the government has since acknowledged that the mark will be hit later in the week.

Vaccination rates for some parts of the population and local government areas remain significantly below the 80 per cent mark.

The double-vaccination rate for Aboriginal people was 46.7 per cent as of yesterday.

For South Australians aged 12-15 years, the rate is lower – 43.15 per cent.

The Government is preparing for a surge in cases in the coming weeks and months, with a focus on home care.

Health Minister Stephen Wade said governments’ new HealthCheck SA app had been built to manage up to 50,000 people, providing at-home monitoring for people, their families and close contacts, while also linking them to support if needed.

“We anticipate that around 85 per cent of positive COVID-19 cases will be safely supported through home-based care and monitoring through the new HealthCheck SA app, freeing up beds in our hospitals for more acutely unwell patients,” he said yesterday.
