Kalgoorlie
A pre-war civil airfield, Kalgoorlie-Boulder airfield housed a RAAF Meteorological Service Office from 1940, until the arrival of No 4 Aircraft Depot (AD) in 1942. The role of this depot was to maintain aircraft based at Pearce and Guildford, and repair engines for the US Navy and Qantas Catalinas operating from the Swan River in Perth.
