Ballarat
In 1940 the Federal Government took over the airport as an air base for the Empire Air Training Scheme. During WWII the base was a RAAF Wireless Air Gunners' School as well as the base for USAAF Liberator bomber squadrons. During the war the airport was made much bigger, with three sealed runways. Two of these were over 2,000 metres (6,550 ft) long and 45 metres (150 ft) wide. The aerodrome remained the RAAF School of Radio until 1961 when it was returned to normal use. The City of Ballarat now runs the airport which is listed on the Victorian Heritage Register for its social and historic importance.
