The Traditional Owners of Purnululu National Park in Western Australia's East Kimberley have launched a petition to State Parliament calling for a formal role in managing the World Heritage-listed landscape.

Purnululu, about 300 kilometres south of Kununurra, is internationally known for the distinctive sandstone domes of the Bungle Bungles, one of Australia's most recognisable natural landmarks.

The area was declared a national park in 1987 and added to the World Heritage list in 2003. Native title over the land was recognised in 2022.

Despite that determination, the park is not jointly managed by traditional custodians and the WA Government, unlike several other national parks across the state where Aboriginal ranger groups and the Department of Biodiversity, Conservation and Attractions share responsibility for land management.

The Bungle Bungle Aboriginal Corporation says Traditional Owners want to be directly involved in managing their Country and have been seeking progress on a joint management arrangement with the State Government.

An e-petition lodged with WA Parliament calls on the government to begin negotiations to establish that partnership.

WA Environment Minister Matthew Swinbourn said the State would "continue to engage with Traditional Owners ... through the Purnululu World Heritage Area Advisory Committee".

The petition, which is open to all Western Australian residents, closes on 28 May and will be presented to Parliament by Greens MP Sophie McNeill.
