Barrow Creek

 was a town in Australia's Gibson Desert, between Darwin and Alice Springs, some 450km northeast of Ayers Rock. Paul Forbes' Landrover broke down near the town because of the extreme desert heat. As he was letting his overheated engine cool, the Seventh Doctor arrived and told him to move three steps to the left. Baffled but compliant, Forbes did so, just in time to avoid being hit by a falling chunk of Skylab. (BE: Three Steps to the Left)
 * ''In reality, the distance between Barrow Creek and Uluru, at least by car, is more like 750km.
