Karlu Karlu Named International Dark Sky Sanctuary in Australia 2026

Karlu Karlu conservation reserve in Australia's Northern Territory has been officially recognized as an International Dark Sky Sanctuary, making it the third in the country. This remote natural landmark, also known as the Devils Marbles, is located about 100km south of Tennant Creek and is celebrated for its ancient granite boulders and exceptionally clear night skies.

What is an International Dark Sky Sanctuary?

International Dark Sky Sanctuaries are places recognized for their exceptionally clear night skies and protected natural environments. These sites are typically in remote areas with little light pollution and are valued for their scientific, environmental, educational, or cultural significance. The designation is difficult to achieve, with only 24 recognized locations worldwide.

Significance of Karlu Karlu

Almost all of the reserve's 1,800 hectares is a sacred site, significant to the Kaytetye, Warumungu, Warlpiri, and Alyawarra traditional owners. The designation represents a commitment to protect and promote the night sky, as stated by Philip Cowan, senior director of NT Parks and Wildlife Operations. Light pollution will need to be considered in any future development, ensuring the preservation of this pristine environment.

The Designation Process

The NT designation followed a submission led by the Department of Tourism and Hospitality, with support from the traditional owners and local councils. Being granted the designation involved an extensive year-long process led by NT Parks and Wildlife. It included six months of night-sky readings to measure darkness levels, a review of artificial lighting, and an assessment of future risks to preserving the night sky.

Australia now has three International Dark Sky Sanctuaries. The other two are Arkaroola Wilderness Sanctuary in South Australia and the Australian Age of Dinosaurs Museum of Natural History in Queensland. Here is a comparison:
