The Nunggubuyu are an Aboriginal Australian people of eastern Arnhem Land in the Northern Territory.
The Nunggubuyu's traditional lands extended over some 2,700 square miles (7,000 km2) southwards from Cape Barrow and Harris Creek to the coastal area opposite Edward Island, and their western boundaries were formed by the Rose and Walker Rivers.
However they do not share the very frequent system of sections and subsections that determine affinal relations in many Australian tribes, but rather interpersonal genealogical relationships undergird the social structure.
[10] The society is structured by a four-fold division covering moieties, phratries, clans and patriarchal lineages.
[citation needed] For this reason Mandaridja people absorb into their totemic systems things that are of foreign provenance, such as ships, planes and tractors.
