Flinders is remembered not only for his achievements but also for great improvements in the science of navigation, for his research on the action of the tides, and the affinity between the height of the barometer and the direction of the wind.

He is also noted and for his investigations into the deviation of the compass through the presence of iron in ships, a small iron rod placed near a ship’s compass is named Flinders bar, as he found it counteracted the vertical magnetism of a vessel.

In failing health he prepared his monumental work A Voyage to Terra Australis; an enlightening and fascinating story of brilliant navigation and discovery, achievement and tragedy, self-sacrifice and devotion. He paid noble tribute to his comrades suddenly swept away off the Unknown Coast; expresses spontaneous gratitude to the people of Mauritius who befriended him in the hour of need, and expressed sympathy and some understanding towards the Aboriginal people he encountered.

His moral character and devotion to duty were based on high ideals. His considerate and just treatment of the men who served with him won their confidence and respect. In his brief but brilliant career he surmounted difficulties and adversity, and his voyage in the Investigator endures as an imperishable monument to his undaunted spirit and outstanding ability.
