It was first set up at Townsville Grammar School, on 25 February 1942. The Women's Auxiliary Australian Air Force members of 3FS lived at St Anne’s Girls School, Townsville. In 1942, a new headquarters for No. 3FS was built at Wulguru, Townsville. The site was a proper military camp site with its own power house, barracks, kitchens, toilets and recreation hall. There were as many as 62 different buildings in 3FS HQ. The camp was on the side of a hill near Mt Stuart, on the west side of the road to Charters Towers. It can still be seen today on the hill on the opposite side of the Stuart Shopping Centre.
