How did Matthew Flinders and Nicolas Baudin contribute to the exploration of South Australia?

In early 1802, the English navigator Matthew Flinders and the French explorer Nicolas Baudin led separate expeditions that were instrumental in charting the southern coast of Australia.1

Flinders, commanding the Investigator, surveyed the entire southern coastline from Cape Leeuwin in the west to the Bass Strait in the east. His work was part of a broader mission to circumnavigate and map the continent, ultimately confirming that Australia was a single landmass.123

Baudin, leading the French expedition in Le Géographe, conducted a similar survey at the same time. While his expedition gathered significant information and assigned French names to various coastal features—such as "Terre Napoléon" for the southern coast—it contributed less in terms of new exploration compared to Flinders's comprehensive charting. The two explorers famously met at Encounter Bay, a location named to commemorate their unexpected encounter during their respective voyages.13
