South Australian health authorities have signed a directive stating that fully vaccinated people are only required to do seven days of quarantine instead of the 14 they were initially mandated to do.
It comes as a decision to further change quarantine restrictions in South Australia could be made as soon as Tuesday as the state closes in on 90 per cent double vaccinated.
Premier Steven Marshall expressed he still hopes South Australia can reach the vaccination milestone before Christmas.
Currently 84.2 per cent of the state is fully vaccinated.
From Tuesday, the Transition Committee is expected to start planning what will take place when that vaccination target is achieved.
It comes as South Australia recorded 13 new COVID-19 cases today, all of which are believed to be of the Delta variant.
