Austral Island is a small Antarctic island in the extreme southern lobe of Penney Bay, in the Windmill Islands. The island appears in air photos taken by USN Operation Highjump (1946–47), but was not charted on subsequent maps. So named by US-ACAN because it is the southernmost of the Windmill Islands.
