South Australia has changed its travel rules for people coming into the state from Greater Brisbane and Byron Bay as the recent outbreak is brought under control.

Currently travellers coming from those two areas need to get a test and isolate until receiving a negative result after arriving in SA.

They also need to be tested on day five and day 13.

But on Wednesday Acting Police Commissioner Linda Williams said these requirements would lift after midnight on Friday for people coming from Byron Bay.

She said the rules would be removed for Brisbane travellers after midnight on Monday.

The staggered reopening was based on the last case of community transmission recorded in Byron Bay and Brisbane, Ms Williams said.

“What it in effect means is that anyone coming into South Australia from those dates does not have to undergo any testing and they will be free to come into the state without any restrictions,” she told reporters on Wednesday.

“The health advice was that once 14-days had lapsed with no community transmission, they were confident to lift the restrictions.”
