The Flinders Ranges could join Uluru-Kata Tjuta National Park and the Great Barrier Reef on the World Heritage List, after the government nominated the South Australian site to UNESCO.
The area has been nominated for a tentative listing as a World Heritage site, on behalf of the South Australian government and the area's traditional owners, the Adnyamathanha people, Environment Minister Sussan Ley said in a statement.
"The Flinders Ranges is known for its outstanding aesthetic beauty, diverse landscapes and rich biodiversity, and exceptional scientific values," Ms Ley said.
"It is also considered to be a window into a major stage in Earth's history known as the 'dawn of animal life', a geological record of wildly fluctuating climate conditions and environments over a period of 350 million years."
The Flinders Ranges will now spend at least 12 months on the tentative list, and will then be considered by two independent advisory bodies.
South Australia's Environment Minister David Speirs said he was proud the region was being recognised on a world scale.
"Achieving World Heritage status requires a place to be aligned with very specific criteria, and strong evidence that the values being nominated are absolutely unique and not replicated anywhere else in the world," he said.
"This tentative listing provides us with an opportunity to celebrate and share this very unique part of South Australia on a global scale."
