The park is managed jointly (together) by the Aṉangu and Parks Australia. Parks Australia is the government body that looks after national parks in Australia. It is a part of the Department of the Environment. The Aṉangu own the land, and lease it to the government. The lease began in 1985 and lasts for 99 years. Decisions are made by the Board of Management, a group of people. Under the lease terms, the Aṉangu always hold a majority on the management board. There are 12 people on the board.
