Dent Island Light is an active lighthouse located on Dent Island, a small island off the coast of Queensland, Australia. Dent Island is part of the Whitsunday Group of the Whitsunday Islands. Located on the south-west tip of the island, the light guides ships passing in the Whitsunday Passage, between Whitsunday Island and the islands to the west, and marks the Dent Island Passage.
From its inception, the lighthouse was closely connected to Cape Cleveland Light. Both lighthouses were recommend, approved, tendered and finally, in December 1879, constructed together.The light went through two upgrades in the 1920s replacing both the oil lamp and the fourth order lens with an incandescent gas mantle and a new lens. In 1983 the light was converted to solar power, and finally in 1987 it was demanned.
The lighthouse is a typical for Queensland, made of a timber frame clad with galvanized iron plates. It is topped by a Chance Brothers lantern room, and painted white with a red dome. A modern ML-300 lantern replaced the original lens.
From its beginning, the lighthouse was closely related to the Cape Cleveland Light. The construction of both lighthouses was recommended by Commander George Poynter Heath, the Chairman of the Queensland Marine Board, in February 1878. The lighthouses were formally approved in April 1878 and tenders for the construction of both stations, each including a lighthouse and two keepers' cottages, were called in May 1878 and closed in June 1878. The tenders were awarded to W. P. Clark, who also constructed Bustard Head Light (1868),Low Isles Light (1877),Double Island Point Light (1884) and Pine Islet Light (1885). However, following personal difficulties, the contracts were transferred to John Clark and James Wiseman who completed the construction of both stations in December 1879.
