History

The first reported sighting of King George Sound by a European was in 1791 by the English explorer George Vancouver
George Vancouver
Captain George Vancouver RN was an English officer of the British Royal Navy, best known for his 1791-95 expedition, which explored and charted North America's northwestern Pacific Coast regions, including the coasts of contemporary Alaska, British Columbia, Washington and Oregon...

, Vancouver named it after the reigning monarch, King George III.

The next Europeans to visit the Sound were whalers Capt. Dennis of The Kingston, and Captain Dickson aboard The Elligood who caught three whales in August 1800. This expedition left an inscribed piece of metal behind to be found by Flinders crew in the following year.

During the course of their stay the ship's naturalist, Francois Peron, collected 1060 new species of shellfish and a large number of starfish from the sound.

Phillip Parker King visited the Sound in 1818 aboard the cutter Mermaid while en route to conduct a nautical survey of the North West Cape, and Frenchman Dumont d'Urville visited it in 1826 aboard the Astrolabe.

A wooden Barque, the Fanny Nicholson was being used as a whaling vessel when it was run ashore during a gale in 1872, the remains can still be seen in the shallow water in Frenchman's Bay.
