All areas are either on pastoral lease or on public land. The pasturalists in question have been very firendly and happy for climbing to take place. This is not the case of all pastoralists in the NT (or anywhere!).
With the all I have made great efforts to ascertain whether these areas are registered sacred sites. None of them appear on any register. The problem is that to the local traditional owners (TO's) all of the rocks and ridges around Alice are sacred. However, the TO's are generally very reasonable and forth coming with which areas they would and would not be happy for climbing to take place.
Fortunately, Alice is populated with a many lifetimes worth of climbing so it is not an issue to find somewhere to climb that is away from sites that are sacred or culturally significant.
