Troughton Island is an island located off the Kimberley coast of Western Australia, about north-west of Kalumburu and north-west of the Mungalalu Truscott Airbase. Troughton Island is used as a helicopter base for the Timor Sea oil rigs approximately 500km (300miles) west of Darwin.
The island was found and named in 1819 by Phillip Parker King. The Sir Graham Moore IslandsAirline company ShoreAir Pty Ltd has opened and operated an airport on the island since the 1960s.[1] It is a reference point for hydrographic surveys.
Under the Köppen climate classification, Troughton Island has a hot semi-arid climate (BSh), bordering on a tropical savanna climate, with a sweltering and oppressively humid wet season from December to March and a hot dry season from April to November.
