What date did Matthew Flinders start his journey around Australia?

Answer:
Matthew Flinders is considered to have started his journey of circumnavigating Australia on 6 December 1801.
In reality, Flinders departed from Sydney much earlier. However, because he started charting the coastline from a point out to sea from Cape Leeuwin in December 1801, this is regarded as the date he began his journey.
