Dent Island Light

Dent Island Light is an active lighthouse on Dent Island, a small island off the coast of Queensland, Australia, part of the Whitsunday Group of the Whitsunday Islands. Located on the southwest tip of the island, the light guides ships navigating 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 recommended, approved, tendered and finally, in December 1879, constructed together. The light had two upgrades in the 1920s, replacing both the oil lamp and fourth-order lens with an incandescent gas mantle and a new lens. In 1983, it was converted to solar power; and was demanned in 1987.

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.
