It's not Qld, but boot up Goigle Earth and have a look along the Transcontinental Railway line. Along the Nullarbor Plain, there are loads of ghost towns Along the track which used to be there to service the railway line.
On that note, has anyone here ever crossed the Nullarbor on the track which follows the railway line? I imagine it would be an awesome adventure, loads of the ghost towns to explore on the way, and you would get to experience the real outback but at the same time the train goes by a couple of times a week so if something did to badly wrong it's not like you'll be stuck forever. It would be great to follow the track in one direction, then for the return trip home you could drive on the Tarmac road and have a look at the coastline.
