 The "Aboriginal Land Rights (Northern Territory) Act" was passed in 1976, meaning that after many years Aboriginal law and land rights were finally recognised in Australian law.Nine years later on 26 October 1985 the traditional owners were presented with the freehold title deeds for the park, who, in turn, leased the land back to the Australian Government through the Director of National Parks (formerly the Australian National Parks and Wildlife Service) for 99 years.The Director is assisted by Parks Australia, a division of the Australian Department of the Environment and Energy.
