From October 2018, it will no longer permissible to climb Uluru. I was quite surprised to hear this, as it had been my understanding that it was already illegal. Apparently that was a request from the Anangu people, the traditional owners of the land. Now it will actually be enforced. (This decision was made by the board of the local national park, not by central government.)
As a side-note, “traditional owners” is an interesting term. I think I first heard the concept expressed this way a few weeks ago, watching an address by President Michel D. Higgins to the University of Melbourne, where he was awarded an honorary degree. Allan Myers, the Chancellor of the University, opened events with an acknowledgement of “the traditional custodians of the land on which we meet”.
