South Australia will lift its coronavirus travel restrictions with Greater Brisbane from Sunday.
The change means people travelling to SA from Brisbane will no longer need to spend 14 days in quarantine.
However, they will still be asked to be tested for coronavirus three times - on days one, five and 12 - if they arrive before Wednesday next week.
The only exceptions will be any people who visited specific high-risk locations at particular times - the Bunnings store at Acacia Ridge, the Sunnybrook Cellars and the Woolworths at Calamvale - who will still be required to quarantine.
Chief Public Health Officer Nicola Spurrier says the easing of measures reflects the latest information from Queensland health authorities on the progress containing a cluster of cases there.
"On the basis of this, we looked at what the risk would be in South Australia, and we've decided that 14 days from when the likely first transmission occurred on the second of January would make it Sunday the 17th," she said.
"So we will cease requirements for people quarantining coming from Greater Brisbane into our state."
No changes are planned for people travelling from NSW.
Under present arrangements, people from regional NSW can enter SA but must have the three virus tests.
The hard border arrangements for Greater Sydney, the Central Coast, the Blue Mountains and the Wollongong regions will remain.
People from those areas are not allowed to enter SA unless they are an essential worker or have an exemption.
SA reported one new COVID-19 case on Friday in a recently returned traveller from overseas.
The state has 10 active infections, all acquired overseas and in hotel quarantine.
