Key figures have joined the community for a gathering in Derby on Thursday to celebrate the new $4m home of the Wilinggin Aboriginal Corporation.

Located close to the Traditional lands of the Ngarinyin people, the Wilinggin Aboriginal Corporation's (WAC) new facility has helped it further protect and promote the interests of the Ngarinyin people.

WAC's operations cover more than 63,000sqkm in Western Australia's eastern Kimberley region, with the dedicated space critical to its ongoing efforts to manage and protect Ngarinyin Country.

WAC board chair Nelson O'Reeri said the new headquarters were proving significant in helping the organisation enhance its deep connection to Ngarinyin heritage.

"These new headquarters represent more than just a building for us - it is a place where our community can come together," he said.

With such an extensive area of Country to care for, WAC's acquisition of the fit-for-purpose headquarters ensured it could continue to preserve Ngarinyin cultural heritage for future generations.

"It's a foundation for our growth, and a testament to our enduring connection to our land and culture," Mr O'Reeri said.

Project partners, directors and community members joined Thursday's milestone celebration of the modern facility, which featured a Welcome to Country and smoking ceremony.

The acquisition of the property was aided by a $1 million contribution from the Indigenous Land and Sea Corporation, in support of WAC's mission to safeguard and restore cultural heritage.

Its new headquarters span over 2000sqm and houses 24 staff - 18 of them Indigenous - enhancing WAC's ability to manage and preserve Country and with extra space essential for the organisation's future growth.

ILSC group CEO, Joe Morrison said WAC's new facility ensured the sustainability of Indigenous culture and traditions.

"We are driven by the fundamental importance of supporting Indigenous communities in their efforts to preserve culture and manage Country," he said.

"Seeing WAC's new headquarters in the flesh gives you an understanding that this is not just about the building itself, but about what it represents to the Ngarinyin people, in their journey towards self-determination."
