Dirk Hartog Island is an island off the coast of Western Australia’s Gascoyne region that is part of the Shark Bay World Heritage Area. It is Western Australia’s largest and most western island, measuring around 80 kilometers long and 3 to 15 kilometers broad. It has a land size of 620 square kilometers and is located about 850 kilometers north of Perth. It was named after Dutch sea captain Dirk Hartog, who first discovered the Western Australian coastline on the 26th parallel south latitude, which extends through the island. A significant environmental rebuilding project on the island has eliminated all invasive livestock and feral animals, with eleven native species now in various stages of return.
