Political map of Australia, New Zealand & the Southwest Pacific 17 October 1803 (Expanding from New South Wales): Baudin’s French exploratory expedition to Australia (1800–1804) (Baudin expedition to Australia) alarmed the British in New South Wales (Colony of New South Wales), who immediately embarked upon efforts to secure their position in the region. In 1802–1803 Matthew Flinders circumnavigated Australia as part of an effort to map the coastline of the continent. Later in 1803 they preempted any plans the French might have for colonization by founding settlements at Sullivan Bay, Victoria, and Risdon Cove, Tasmania. Although both settlements would soon be abandoned, Risdon Cove would be relocated to Hobart to form the basis for modern Tasmania.
