Dirk Hartog Island is an island off the Gascoyne coast of Western Australia, within the Shark Bay World Heritage Area. It is about 80km long and between 3 and 15km wide and is Western Australia's largest and most western island. It covers an area of 620km2 and is approximately 850km north of Perth. It was named after Dirk Hartog, a Dutch sea captain, who first encountered the Western Australian coastline close to the 26th parallel south latitude, which runs through the island. After leaving the island, Hartog continued his voyage north-east along the mainland coast. Hartog gave the Australian mainland one of its earliest known names, as Eendrachtsland, which he named after his ship Eendracht, meaning "concord".
