Within the Thamarrurr Region, there are three main ceremonial groups, encompassing seven language groups and over 20 clan groups. These clans are patrilineal land owning groups, with estates and boundaries delineated. The statutory land trust – DRPKALT, holds the land on behalf of the traditional owners from each estate in the Thamarrurr Region. This is inalienable freehold land, held under the Aboriginal Land Rights (Northern Territory) Act 1976.
Thamarrurr provides an identity to people in the Region through their relationships to land and kin. It also provides a fundamental basis for leadership and governance in the Region. This is the basis from which Thamarrurr Development Corporation is endorsed and operates.
