Captain Matthew Flinders (16 March 1774 – 19 July 1814) was a Royal Navy officer, navigator and cartographer who led the first inshore circumnavigation of mainland Australia, then called New Holland. He is also credited as being the first person to utilise the name Australia to describe the entirety of that continent including Van Diemen's Land (now Tasmania), a title he regarded as being "more agreeable to the ear" than previous names such as Terra Australis.
Flinders was involved in several voyages of discovery between 1791 and 1803, the most famous of which are the circumnavigation of Australia and an earlier expedition when he and George Bass confirmed that Van Diemen's Land was an island. While returning to Britain in 1803, Flinders was arrested by the French at the colony of Isle de France. Although Britain and France were at war, Flinders thought the scientific nature of his work would ensure safe passage, but he remained under arrest for more than six years.
