South Australian Premier Steven Marshall has confirmed his state will not go into lockdown after five cases of "linked transmission" were recorded today.
Instead, home gatherings will be reduced to just 10 attendees, and masks are now recommended when South Australians are out in public.
The new restrictions come after the state recorded five new cases of what the Premier has called "linked transmission" a man, his wife and three of his four children.
The man is a worker at the Tanami mine in the Northern Territory and has been in isolation with his family since Saturday 26 June.
The family has since been transferred to SA's quarantine hotel in the Adelaide CBD.
"While this is a very concerning turn of events we are very relieved that this person and his family have been at home since Saturday," SA Premier Steven Marshall said.
"We do know that this Delta variant is particularly worrying, we're seeing further deterioration of the situation around the country again today, so we all must remain extraordinarily vigilant."
In addition to the new home gathering limit and recommendation South Australians wear masks in public, the Premier has also advocated people work from home if possible.
The restrictions build on already announced COVID-19 rules for SA which include the banning of dancing and the reintroduction of the one person per two square metre rule.
The news comes after Northern Territory Chief Minister Michael Gunner imposed a snap lockdown for Alice Springs from 1pm today.
That lockdown is in response to the movements of the infected Adelaide man who spent an extended period at the Alice Springs airport last Friday.
