1925 a hangar was built for government use and in 1927 a hangar was built for Qantas. Aviation pioneers such as Charles Kingsford Smith, Charles Ulm, Bert Hinkler and Amy Johnson used the airport. The site ceased operation as an aerodrome in 1931, although it continued to be used for gliders. However, in World War II, the site was refurbished in 1942 as a major airbase for the US Pacific Military Command. This involved covering the site with fill of variable depth. After the war, in 1949 Eagle Farm became Brisbane's main airport, known as Brisbane Airport. In 1988 the airport closed again, aviation moving to the present Cribb Island site as Brisbane International Airport. The women's prison site then became an open grassed area. The site remains one of only six surviving in Brisbane from the convict period, with the former Moreton Bay penal settlement being one of only seven sites in Australia associated with secondary punishment. Description The old Eagle Farm airport, of which the site of the former Eagle Farm convict settlement forms part, is bounded on the south by Lamington Avenue and the Pinkenba Railway, to the east by Viola Place, to the west by the Gateway Arterial Road, to the north-west by a drainage channel and to the north-east by Lomandra Drive and Cassia Place. The land in the centre of the area is now flat and featureless, apart from remnant structures from WWII and the remains of runways from the post- war development of the airport. Virtually none of the old airport area exists as it did prior to European settlement. Only the foundations of the Eagle Farm Settlement survive, having been covered with fill in 1942. The Allison Engine Testing Stands and Second World War Hangar No. 7 from World War II also survived on the former airport site and are both separately heritage-listed. Heritage listing Eagle Farm Women's Prison and Factory Site was listed on the Queensland Heritage Register on 7 February 2005 having satisfied the following criteria. The place is important in demonstrating the evolution or pattern of Queensland's history. The Eagle Farm Women's Prison and Factory Site is significant as one of few sites surviving in Brisbane from the convict period and a remnant of only seven sites associated with secondary punishment in Australia. Further, the Women's Prison and Factory Site is one of even fewer sites, both in Brisbane
