Adolphus Island - WA

Adolphus Island is an uninhabited island located in the Kimberley region of Western Australia. It is situated in Cambridge Gulf approximately 35 kilometres north of Wyndham and covers an area of about 4,157 hectares (10,272 acres). The island has a maximum height of approximately 235 m.
The island, the gulf and many other features surrounding the gulf were named by Philip Parker King who visited the area in 1819 aboard the survey cutter HMS Mermaid but left after spending eleven days charting the gulf, being unable to find supplies of freshwater in the mudflats, rivers and hills that surround the Cambridge Gulf. King named the island after the Duke of Cambridge at the time, Prince Adolphus
