Welcome to Coober Pedy - the international capital of opal! The semi-precious stone has presided over the destiny of this unusual town where water is rare, dust invasive and the climate OTT. To escape the scorching temperatures, half the inhabitants chose to live underground in troglodyte houses. The moonlike landscape around the town is dotted with mounds and mining shafts, making it ideal for movies like Mad Max 3 or The Adventures of Priscilla.
