Tamba Banks of the Jaru tribe, whose family once lived in the Bungle Bungles, [known to her people as Billingjal], is one of the traditional owners of the Purnululu national park. Bungle Bungle is the 'whitefellas's' name for the range of rocks: Purnululu is an aboriginal word but the correct term for the rocks is Billingjal meaning 'sand falling away' which is what hapens when the fragile earth is cracked.
