The traditional owners of Uluṟu–Kata Tjuṯa National Park (Nguraritja) and the Federal Government's Director of National Parks share decision-making on the management of Uluṟu–Kata Tjuṯa National Park. Under their joint Uluṟu–Kata Tjuṯa National Park Management Plan 2010–20, issued by the Director of National Parks under the "Environment Protection and Biodiversity Conservation Act 1999", clause 6.3.3 provides that the Director and the Uluṟu–Kata Tjuṯa Board of Management should work towards closure of the climb and, additionally, that it was to be closed upon any of three conditions being met: there were "adequate new visitor experiences", less than 20 per cent of visitors made the climb, or the "critical factors" in decisions to visit were "cultural and natural experiences". Despite cogent evidence that the second condition was met by July 2013, the climb remained open.
