Australia has 95% of the world’s supply of commercial opal and the largest percentage comes from the 70 opal fields around Coober Pedy. Half the residents live underground in dugouts to escape the searing summer temperatures. Once a year in the cooler month of May, Coober Pedy is the location for The Great Breakaway Marathon (formerly Breakaway Bolt). On this flightseeing holiday you will experience life in this most unique town as well as run, walk or watch the Marathon. Enjoy fantastic scenic flying over Flinders Ranges, Wilpena Pound, Lake Eyre and more.
