The Eagle Farm Airport served as Brisbane's main airport until the opening of the present Brisbane Airport in 1988. During WWII U.S. Navy Seabees of the 55th CB built Camp Seabee adjacent to Australian CCC Camp by the Airport as a staging center for Construction Battalions assigned to MacArthur's 7th Amphibious force. It was the smallest of the military installations at Eagle farm. They also built an adjoining Advance Base Construction Depot (ABCD) and the USN Ordnance depot at Mt. Coot-Tha. CBs that were there were the 19th, 55th, 60th, 77th, 84th, 91st, 104th and the CBMU 564. The base operated from March 1943 until mid October 1945. The Royal navy moved into Camp Seabee and the Australian Army took over the ABCD and Ordnance depot.
