The Nyangumarta claim is determined, but YMAC continues to represent the Nyangumarta People in their future act and heritage matters.

The ILUA (incorporating a joint management agreement) is now operative, having been signed by the state government in December 2014. The ILUA acknowledges that the Nyangumarta People will pursue other opportunities to protect and manage conservation and cultural values in their determination area.
The inaugural joint management body meeting was held on 29 April 2015 and a management plan has been developed for the Eighty Mile Beach Marine Park.
