Mawson sailed from Hobart on 2 December 1911 ~ and returned to Australia three years later. His expedition planned to map part of King George V Land ~ the nearest Antarctic coastline to Australia. The expedition made numerous discoveries which were subsequently recognized by the award of medals from various national agencies.
The Australian Antarcic Expedition is best known for the adventure of Mawson and his small team of two other men ~ Lieutenant Belgrave Ninnis and Xavier Mertz.
On a lengthy journey away from the expedition's main base (mapping ~ taking geological samples ~ discovering stuff) Mawson's team ~ of three ~ suffered several tragedies. These are retold at length in a variety of other sources (eg Wikipedia) ~ and abridged here.
Mawson trekked on ~ knowing that ~ with the onset of gales and sea ice ~ the Aurora was scheduled to return to Australia very soon. Fortunately arrangements were made to leave a shore party behind to overwinter, and to search for the party who had not returned. The Aurora delayed sailing for as long as possible before leaving. Mawson staggered back to camp ~ almost unrecognizable ~ just a few hours after the Aurora had left.
The base radio station was able to ask for a recall of the ship ~ but the high winds and seas of the approaching Antarctic Winter meant the Aurora could not manage to return to the shore. So the party remained ~ to be rescued months later when the season allowed.
Born in Yorkshire, Mawson was brought up for all his life in Australia. He later served for the British forces during the Great War, and lead another expedition south from 1929-1930. Latterly he worked as Professor of Geology and Mineralogy at the University of Adelaide. Numerous streets and buildings are named after him, as is a suburb of Canberra.
