On the 8th of June 2005, Argyle Diamonds Limited (Argyle) and Traditional Owners of the Argyle Diamond Mine in the Kimberley region of Western Australia celebrated the registration of an Indigenous Land Use Agreement (ILUA). The ILUA was the culmination of almost three years of negotiations, between Argyle and the Traditional Owners and the Kimberley Land Council. The ILUA replaces the Good Neighbour Agreement (1980) and Good Neighbour Program (1981). The ILUA was registered by the National Native Title Tribunal (NNTT) on the 8th of April 2005. It was the third ILUA to be registered in Western Australia.
