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. 

On 6 October 2022, the Federal Court of Australia made two different determinations, both which related to the larger Cape York #1 United claim. The Cape York #1 United claim covers the majority of the area of Cape York, covering various types of tenure, including pastoral lease, protected areas, reserves and areas of unallocated State land. Relevantly though, Mortimer J recognised the rights of the Gudang Yadhaykenu People and nominated the Gudang Yadhaykenu Native Title Aboriginal Corporation to hold native title in trust for the benefit of the native title holders.
