Returned travellers and others in quarantine at a hotel in Adelaide have been told they will be moved and required to start their 14-day isolation period again.
The Peppers Hotel in Adelaide is considered the source of a current cluster of COVID-19 cases centred on one extended family living in the city's north.
It's believed a cleaner at the hotel picked up the virus from a surface and passed it on to other family members.
So far about 20 infections are confirmed with health officials scrambling to contact trace and place people in home isolation.
"We understand the frustration of the guests and we thank them for their assistance as we take every required step to prioritise the health and safety of all South Australians," SA Health said in a statement.
"We phoned guests before providing written information to them about the move and additional information will be provided once more details are confirmed."
SA Health said the hotel would be thoroughly deep cleaned to allow it to continue as a quarantine site in the future.
SA officials on Monday also suspended all international plane arrivals planned for this week, to ensure enough space was available to quarantine locals who needed to isolate in relation to the current cluster.
