Test flight from mainland Australian to edge of the Antarctic zone

Lincoln A73-2 from No 1 Air Performance Unit at Point Cook, Victoria, conducted a pioneering flight from mainland Australia to the edge of the Antarctic zone, collecting meteorological data and photographing Macquarie Island which lies 1466 kilometres south of Tasmania. The aircraft was airborne for 14 hours 35 minutes and completed the flight in deteriorating weather. This effort was seen as an essential precursor to the scientific voyages launched by the Australian National Antarctic Research Expedition (ANARE) from December 1947.
