Deep in northeast Australia's outback, underneath grassy eucalypt woodlands and vast grazing lands scattered with cattle stations, lies one of the world's largest known untapped coal reserves.
Queensland's Galilee Basin, an area roughly the size of Britain, is set to produce its first coal in 2021, to be moved by rail 300 kilometers to the coast, where it will be loaded onto cargo ships that will sail through the Great Barrier Reef to ship it to Asia.
