Effective immediately, South Australians over the age of 18 will now be eligible to get their third dose of the Covid-19 vaccine after three months – instead of four.

Premier Steven Marshall announced the news in a press conference today, which is based on updated health advice and follows similar moves by the NSW and Victorian governments this morning. He said 60 per cent of eligible South Australians have already received their booster.

“This next step in our Omicron response plan... will maximise our booster coverage, arming even more South Australians against the new variant by providing even better protection for the entire community,” the premier said.

“The more South Australians get boosted, the sooner we can look to reduce restrictions and get back to a more normal life.”

The news comes as South Australia records 3482 new cases of coronavirus and another six deaths, taking the state’s total number of fatal cases since the start of the pandemic to 50.

Marshall said today's daily case numbers were again below the seven-day average and "another clear indication that we are at or around the peak here in South Australia".

More to come.
