A COVID-19 outbreak at Koonibba in South Australia's far west is growing, as authorities increase testing for the disease.
SA Health data shows there are 76 active cases in the District Council of Ceduna, which includes the Aboriginal community of Koonibba where many residents have been forced into isolation.
Health authorities opened a drive-through testing site at the Ceduna Blues Sports Club on Monday to help get on top of the spread.
Ceduna Aboriginal Corporation chief executive Wayne Miller said health workers in Koonibba were thorough in their administering of the tests.
He said local events like funerals and large gatherings had been curtailed.
"While we start to see outbreaks, I think we need to modify all of those things to best protect community.
"It's a really good and wise move that the Koonibba community have done to limit attendance numbers because … we don't want them to turn into superspreader events."
The lack of mobile coverage in Koonibba was proving a challenge, he said.
"We've got a community that doesn't have mobile phone coverage, so even getting important health messages to them is a concern.
"There are a number of strategies that have been put in place or are going to be put in place to try to improve that."
In a statement, SA Health said it had been working with Aboriginal community leaders and councils for 19 months to develop plans to deal with potential outbreaks.
SA Health said it was assisting local authorities with increased testing and other supports.
It said about 72 per cent of people in the Ceduna local government area aged 12 and above were fully vaccinated.
The agency has also opened a new drive-through testing clinic at the Ravendale Sporting Complex in Port Lincoln.
