The Kaapay Kuuyun Aboriginal Corporation are the registered native title body corporate and hold native title in trust for the benefit of the Kuuku Ya’u and Uutaalnganu (Night Island) Peoples.  

On 25 November 2021, Mortimer J made a positive native title determination in relation to the Kuuku Ya’u People’s land, which formed part of the greater Cape York #1 United Claim.  

The Barra Parrapi (Aboriginal Corporation) RNTBC holds the native title in trust for the native title holders. 

Prior to the proceeding on 29 November 2021, the parties had reached an agreement to the terms of a determination of native title, making the Nangaanya-ku Application. The lands and waters subject to the Nangaanya-ku Application intersected by mining leases M39/139 and M39/1096; no determination was made over that land.
