Warren Macdonald (born 1965 in Melbourne, Victoria, Australia) is an Australian environmentalist, explorer, mountain climber, motivational speaker, and writer. In April 1997 Warren Macdonald was climbing on Hinchinbrook Island, Northern Australia when a giant boulder fell on his legs. Warren survived the accident thanks to Geert van Keulen, a Dutch traveller Warren had met the day before, who raced down the mountain for help. He spent two days out in the open and both his legs were amputated at the thigh.
