Return to Hobart
The expedition returned to Hobart on 19 March 1931, with the work undertaken by the party used by the British Order in Council to reaffirm British sovereignty to the area and then pass control to the Commonwealth of Australia. The expedition achieved much over the two austral summers, with much of the coastline mapped for the first time and demonstrating the coastline was continuous from the Ross Sea to Enderby Land. The scientific work undertaken took many years to gather and prepare, with much appearing in scientific reports but some still unpublished today. The main achievements of the expedition were, however, in marine science, which included extensive oceanographic work and marine sampling.
