The extent of coastline freshly discovered by him was not so great as that first explored by some of his predecessors.

But no former navigator pursued extensive new discoveries so minutely, and, consequently, found so much to name; while the precision of Flinders' records left no doubt about the places that he named, when in later years the settlement of country and the navigation of seas necessitated the use of names.
Compare, for instance, in this one respect, the work of Cook and Dampier, Vasco da Gama and Magellan, Tasman and Quiros, with that of Flinders.
Historically their voyages may have been in some respects more important; but they certainly added fewer names to the map.

There are 103 names on Cook's charts of eastern Australia from Point Hicks to Cape York; but there are about 240 new names on the charts of Flinders representing southern Australia and Tasmania.

He is the Great Denominator among navigators.

He named geographical features after his friends, after his associates on the Investigator, after distinguished persons connected with the Navy, after places in which he was interested.
