The Western Australian government has formally recognised a new partnership with Aboriginal leaders in the Kimberley, aimed at improving wellbeing outcomes for young people across the region.

The agreement, developed between the Cook Government and the Kimberley Aboriginal Regional Governance Group, was marked at a ceremonial event in Broome on Thursday.

Known as the Kimberley Aboriginal Youth Wellbeing Steering Committee Partnership Agreement, the framework is intended to reshape how state agencies and Aboriginal organisations work together — with an emphasis on shared decision-making and coordinated action.

The agreement seeks to strengthen collaboration between Kimberley Aboriginal community organisations and government agencies, with the goal of delivering better, more consistent outcomes for Aboriginal youth.

It also builds on work already underway in response to the State Coroner's Message Stick report, which examined Aboriginal youth suicide in remote parts of the state and called for systemic reform.

Kimberley MLA Divina D'Anna said the agreement reflected sustained advocacy from communities across the region.

"Our government has been working hard to formalise this partnership, and I thank the community for its advocacy and support as we work together to do what's best for our youth," she said.

"Every region has unique needs, and we know the best way to achieve positive, lasting outcomes is to work together."

WA Mental Health and Health Minister Meredith Hammat said the agreement formalised an existing commitment to the region.

"This partnership agreement formalises our existing commitment to improving the wellbeing of young Aboriginal people in the Kimberley," she said.

"I feel confident this partnership agreement will build on existing activity to foster real and long-lasting change for Aboriginal people, families and communities."
