A historic tri-partite Land Use Agreement has been signed for Western Australia's East Kimberley Region, traditional lands of the Ngarinyin people.

The innovative El Questro Wilinggin Indigenous Land Use Agreement, which has been reached between the Traditional Owners of the East Kimberley, tourism operator G'Day Group, and the Western Australian government, sees 165,000 hectares converted to freehold and reserve.

The deal will provide a major boost to the region's social and economic growth, with popular tourist destinations El Questro Station and Wilderness Park leased to Australia's largest park network operator G'Day Group by Traditional Owners.

Traditional Owners were represented by Wilinggin Aboriginal Corporation at the Agreement's signing alongside Aboriginal Affairs Minister Dr Tony Buti, Lands Minister John Carey and G'Day Group chief executive Grant Wilckens at a recent Parliament House ceremony.

Wilinggin Aboriginal Corporation general manager Paul Lane said the Agreement directly benefits the Traditional Owners of the East Kimberley in multiple ways.

"The conversion of the land which is from currently pastoral across to managed reserve is done without any any detriment to our native titles," he said.

"So we've removed the pastoralists from from the exercise, and that's always a critical piece for us about getting our land back under our control."

Mr Lane said under the Agreement the Ngarinyin people will have more control and recognition of activities on their traditional lands.

"The central piece of that is whatever it's done on that managed reserve area now is to be determined by us," he said.

"And the recognition by people who are developing commercial activity on our country, that they're doing it on our country, and they have to engage with us about it."

Mr Lane believes that similar arrangements may be made in other areas of Western Australia in the future.

"This precedent now opens the gate for this sort of sort of action right across Western Australia," he said.

Western Australian Lands Minister John Carey said the Agreement supports the region's Traditional Owners whilst also responsibly bolstering the East Kimberley's tourism sector.

"The McGowan Government is deeply proud to support the El Questro Wilinggin Indigenous Land Use Agreement which will see positive outcomes for both the Traditional Owners and the tourism industry," Mr Carey said.

"This agreement will not only ensure economic activity continues to flow through to the wider region, but it also sets out to be environmentally responsible through sustainable land use and management practices."

The Agreement sees the majority of El Questro, located south of the Gibb River Road converted from pastoral lease to a 99-year lease agreement with tourism operator G'Day Group who will commit to provide training, development, and employment opportunities for the area's local young people.

Western Australian Aboriginal Affairs Minister Dr Tony Buti said the agreement provides long-term opportunities for the East Kimberley's Traditional Owners.

"This landmark agreement provides sustainable and lasting opportunities for the Traditional Owners, the Ngarinyin people," Dr Buti said.

"It represents the potential for greater economic independence and self-determination for the Ngarinyin people, for today, and long into the future."

Including thermal springs, salt flats, deep gorges and rainforests, Wilderness Park includes some of the most unique landscapes found in Western Australia.

Kimberley Member of the Legislative Assembly Divina D'Anna said the Agreement will provide sustained growth in the Kimberley's diverse east.

"I'm proud to be part of the McGowan Government as we have finalised this historic Indigenous Land Use Agreement with the Ngarinyin people of the East Kimberley and G'Day Group," Ms D'Anna said.

"This agreement will also provide job opportunities for people in the Kimberley, while ensuring the Kimberley region continues its economic and social growth into the future."
