Lady Elliot Island Light is an active lighthouse located on Lady Elliot Island, the southernmost coral cay of the Great Barrier Reef, 46 nautical miles (85 km; 53 mi) north-east of Bundaberg, Queensland, Australia.

It was the third lighthouse erected in Queensland after its formation in 1859 and the first in Australia to be constructed of a timber frame clad with iron plates.

Lady Elliot Island was one of the locations mentioned by the committees as a possible suitable site for the construction of a lighthouse.

[10] This was made worse by a herd of goats which were imported for meat and milk, which ate all growing vegetation.

[11] As the island had little topographical features to offer protection, to begin with, the station was completely unprotected from the powers of nature.

Unlike previous lighthouse using bolted segments of cast iron, the first of which were Troubridge Island Lighthouse constructed in 1856 in South Australia and the original Breaksea Island Light constructed in 1858 in Western Australia, as well as Sandy Cape Light and Bustard Head Light in Queensland, the tower used wrought iron[12] plates mounted on a timber frame which supplied the structural strength, where the iron plates act as cladding.

[10] The iron cladding was prefabricated in England and shipped to the island in pieces,[8] together with the imported lens, lantern and operating apparatus.

[17] The second half of the 20th century marked the re-vegetation of the island, which was to result in the final deactivation of the lighthouse.

[19] Casuarina trees which were planted by Don Adams in 1969 were allowed to grow over the years, and by 1995 the light was obscured.

The tower is made of a timber frame clad with galvanised wrought iron plates, about 2.5 millimetres (0.098 in) thick.

The cottages, set in a row, are located about 50 metres (160 ft) from the lighthouse, as was the practice at the time.

[20] Other structures in the compound include a boat shed, as well as solar panels and weather recording equipment.
