as he was a career diplomat, was not knighted and did not inherit any titles of nobility. Mining for guano In 1863, Mr J. Askunas won tender from the Queensland Government to mine the island for guano for 300 pounds per annum for 10 years. The lease was transferred to Dr W.I. Crowther of Hobart on 23 August 1864. Dr Crowther mined the island until the end of 1873. The guano was mined by Chinese and Malay workers and sent to mainland Australia and New Zealand. Over this period virtually all the trees were removed, as well as 3 feet of top soil and guano. In 1874, the guano mining ceased, but the damage to the vegetation of the island was absolute. It was not until 1966 that a revegetation program was undertaken by lighthouse staff. Their efforts were quickly rewarded, with the island re-emerging as a haven for all types of seabirds. Lighthouse The first lighthouse to be built on the island was constructed in 1866. It was the third lighthouse built in Queensland and the first to be built offshore on the Great Barrier Reef. The original structure was destroyed by a cyclone six years later. In 1873, another lighthouse was constructed, Lady Elliot Island Light. The lighthouse is on the National Heritage list because it is a timber-framed construction with a cast iron cladding, which was premade in England and shipped to the island in pieces. This lighthouse is tall and shone out approximately to sea. The old lighthouse was used continuously until 1995 but became too short for the surrounding vegetation, which was interrupting the beam of light. At this time the Australian Maritime Safety Authority built a new light tower. It is tall and its six light beams shine out to sea. It is solar powered, fully automated and runs continuously. The original lighthouse was placed on the Commonwealth Heritage List in 2004. The Lady Elliot Island Lightstation Heritage Management Plan was developed by the Great Barrier Reef Marine Park Authority (GBRMPA) in March 2012 to protect, conserve and manage the Commonwealth Heritage values of the Lady Elliot Island lighthouse. Airstrip and resort In 1969, Don Adams (who later went on to found Seabird Aviation) built an airstrip and accommodation on the island, and was granted a tourist recreation lease by the Australian Government. In 1977, Don Adams sold the lease to Barrier Reef Airways.
