Allen Island, also known as Allens Island or Allen's Island,[1] is one of the South Wellesley Islands, in Queensland's Gulf of Carpentaria. It was named by Matthew Flinders after John Allen, a Derbyshire miner who was a member of the party of naturalists that accompanied the 1801–1803 voyage of HMS Investigator under Flinders.[2] Flinders landed a party of botanists on the island on 20 November 1802 to search for plants.[3]
It is notable for being directly east of Point Parker, the proposed northern terminus of a still-born land grant railway from Charleville. Point Parker, though a prominent feature, is not always labelled on maps.[4]
