At present, three groups contest
ownership in the Canberra area: the Ngambri, the Ngarigo, and the
Walgalu speaking Ngambri-Guumaal, represented by Shane Mortimer, with widespread connections from across the
Snowy Mountains up to the
Blue Mountains. According to settlers living in the area in the 1830s, such as quoted in the
Queanbeyan Age, there were three groups in the region: the Ngunnawal, the Nyamudy/Namadgi and the Ngarigo. The present dispute originated when the Chief Minister of the Australian Capital Territory at the time,
Jon Stanhope, inaccurately stated that "Ngambri is the name of one of a number of family groups that make up the Ngunnawal nation." He went on to say that "the Government recognises members of the Ngunnawal nation as descendants of the original inhabitants of this region." He made the error after talking with multiracial people of part Ngunnawal descent, whose forebears had come from Yass in the 1920s to find work. In 2012 research for the ACT Government, "Our Kin, Our Country", found "there is no basis within the description of the country supplied by Tindale. The research confirmed that the language spoken in the Canberra region was a dialect of Ngarigu, "related to but distinguishable from the dialects spoken at Tumut and Monaro'". The report stated that evidence gathered historically was too scant to support any family's claims to be original owners. Some Canberra-area Aboriginal people in inland southeast Australia, including
Matilda House, identify as Ngambri.
Shane Mortimer defines himself as one of the Ngambri-Guumwaal, Guumwaal being a language name said to mean "high country". This claim to be a distinct nation is disputed by many other local Aboriginal people who say that the Ngambri are a small family who took their name from the Sullivan's Creek area located to the east of
Black Mountain in the late 1990s. ==Native title==
