Mawson turned down an invitation to join Robert Falcon Scott's Terra Nova Expedition in 1910; Australian geologist Griffith Taylor went instead. Dawson chose to lead his own expedition, the Australian Antarctic Expedition, to King George V Land and Adelie Land, the sector of the Antarctic continent immediately south of Australia, which at the time was almost entirely unexplored. The objectives were to carry out geographical exploration and scientific studies, including visiting the South Magnetic Pole.
