Point Cloates (Coordinates: ), formerly known as Cloate's Island, is a peninsula approximately 100 kilometres south south-west of North West Cape, in the Pilbara region of Western Australia. It features Point Cloates Lighthouse and the ruins of a previous lighthouse (built in 1910); both buildings are on Cloates Hill, which rises 41 metres (134.5 feet) above sea level.
During the 17th and 18th centuries, the first European mariners to see Pt Cloates believed the area between the point and North West Cape to be a small island, which became known to them as "Cloat's Island" (see the box inset, right). The "island" was often confused with other geographical features; these errors led to it being mismapped, as well as suggestions that its existence was doubtful, or that it was a phantom island.
On 1 May 1622, John Brooke, captain of the Tryall claimed to have sighted an island in the area, while en route from England to Batavia (Jakarta), in the Dutch East Indies. (The Tryall was wrecked shortly afterwards, on the rocks that now bear its name, north of the Montebello Islands.)
The name "Cloate's" or "Cloat's Island" originated with a European mariner named Nash, who in 1719 named it after one of the owners of his vessel, a Flemish "baron". Nash is believed to have been English, and the spelling may be an anglicisation of the Flemish surname Cloot. Nash was commanding a "Flemish" (probably Austrian Netherlands) ship, House of Austria, en route from Ostend to a port in China. Nash estimated that the island was "32 leagues" (approximately 180 kilometres) in length.
Guthrie's world map of 1785 shows the island at 97° east longitude, due south of Keeling Island, which is 16 degrees west and more than 1,600 kilometres east of Pt Cloates. Such errors led some cartographers to classify Cloats Island as a "doubtful" or "phantom island". For instance, James Horsburgh wrote in The India Directory, first published in 1809, that: "Cloates Island very probably has no real existence."
The ruins of the first Pt Cloates Lighthouse, built in 1910, are listed in the Western Australian register of heritage places (2005).
