An area of the Swan Reach Conservation Park is now an official international dark sky reserve.
Last week’s announcement follows years of campaigning and is only the 15th recognized area in the world with this status.
The park’s sky darkness is measured at levels making it one of the darkest places in the world.
South Australian astronomer Andrew Cool said the designation of the reserve would be a boost for science, environmental conservation and eco-tourism.
Mr Cool also said “Light pollution is a major problem worldwide, which is why reserves like this are so incredibly unique and important.
