This is an expedition through the Great Victoria Desert, the largest desert in Australia, and through the Nullarbor, the world's largest limestone plain. These are two of Australia's great arid regions. We follow the Anne Beadell Highway from Coober Pedy to the West Australian goldfields, visiting the remote Emu Fields, the site of two British nuclear tests, along the way. The focus in the Great Victoria Desert is on the ever changing vegetation of this "green" and diverse desert. The return trip traverses the Nullarbor plain, following faint rabitters tracks. From Watson on the Continental Railway Track we briefly return to the Great Victoria Desert to visit Maralinga, another British nuclear test site.
