The Swan River Colony was a British colony established in 1829 on the Swan River, in Western Australia.
The name was a pars pro toto for Western Australia. In 1832 the colony was renamed the Colony of Western Australia, when the colony's founding Lieutenant-Governor, Captain James Stirling, belatedly received his commission. However, the name "Swan River Colony" remained in informal use for many years afterwards.
The first recorded Europeans to sight land where the city of Perth is now located were Dutch sailors. Most likely the first visitor to the Swan River area was Frederick de Houtman on 19 July 1619, travelling on the ships Dordrecht and Amsterdam. His records indicate he first reached the Western Australian coast at latitude 32°20' which would equate to Rottnest or just south of there. He did not land because of heavy surf, and so proceeded northwards without much investigation.
On 28 April 1656, the Vergulde Draeck (Gilded Dragon) en route to Batavia (now Jakarta) was shipwrecked 107 km north of the Swan River near Ledge Point. Of the 193 on board, only 75 made it to shore. A small boat that survived the wreckage then sailed to Batavia for help, but a subsequent search party found none of the survivors. The wreck was rediscovered in 1963.
In 1658, three Dutch Republic ships, also partially searching for the Vergulde Draeck visited the area. The Waekende Boey under Captain S. Volckertszoon, the Elburg under Captain J. Peereboom and the Emeloort under Captain A. Joncke sighted Rottnest but did not proceed any closer to the mainland because of the many reefs. They then travelled north and subsequently found the wreck of the Vergulde Draeck (but still no survivors). They gave an unfavourable opinion of the area partly due to the dangerous reefs.
