Naval Base Brisbane was a major United States Navy base built in the early part of World War II at Brisbane, Queensland, Australia. At first, operated as a base for patrol aircraft and convoy escort aircraft to protect the last leg of the Pacific War to the Southwest Pacific. As the US Navy expanded in the island hopping campaign, Naval Base Brisbane expanded to include a submarine base, repair depot, seaplane base and other facilities. US Navy operations started on April 14, 1942, and ended after the war in 1945.

Australia entered World War II on September 3, 1939, being a self-governing nation within the British Empire. The United States formally entered the war on December 7, 1941, following the Japanese bombing of Pearl Harbor. On April 14, 1942, the USS Griffin (AS-13) and a fleet of eleven S-class US submarines arrived at Brisbane's New Farm Wharf. The wharf had a few storage sheds and some other support facilities, which the US Navy rented using the reverse Lend-Lease program, but a much larger facility was needed as a staging area. The US Government hired Australian construction crews to build a new staging area using mostly Australian supplies but with Quonset huts shipped in.

The S-class submarines' first mission was supporting the Solomon Islands campaign. Later, Gato-class submarines were added to the fleet. By the end of the war the Brisbane submarine fleet had sunk 117 enemy ships, totaling 515,000 tons, and rescued many downed airmen. In the spring of 1943, more space was needed and on March 24, 1943, the US Navy Seabee's 55th Battalion arrived and built "Camp Seabee", 5 miles north-east of Brisbane, at Eagle Farm. Camp Seabee became a staging camp for Seabees and their equipment in island hopping operations. The first departure was half the Seabees, to build Naval Base Milne Bay in New Guinea on May 23, 1943. Some Seabees departed to build an airfield at Merauke in New Guinea and others to Port Moresby, New Guinea. Most returned at the end of the construction for R&R. The Brisbane Seabees built a mine depot outside of Brisbane. The next departure was most of the Brisbane Seabees going to Palm Island and Cairns. At Palm Island, Seabees built Palm Island Naval Air Station and Palm Island Seaplane Base. Seabees built the Cairns Harbor PT-Boat Base and Cairns Harbor Seaplane Base. At Cairns, Seabees built the Cairns Airfield used for patrols and a staging camp. On June 19, 1943, the Seabee 84th Battalion arrived at Camp Seabee, with half the Battalion departing to continue the expansion at Naval Base Milne Bay. The 55th and 84th Battalion continued to build up Naval Base Brisbane. Seabee built a mine depot, more barracks at Camp Seabee, a Merchant Marine anti-aircraft training camp, and Mobile Navy Hospital No. 9. In May 1943, Seabee 60th Battalion arrived at Camp Seabee. On January 20, 1944, Seabee Construction Battalion Maintenance Unit 544th arrived to service the Naval Base Brisbane Bases. At Hamilton, Queensland Seabee built a ship-repair depot was built. Outside of the base, a ammunition depot was built. The 55th Battalion built and operated a sawmill. By March 1994 the base had 90,000 square feet of depot warehouse space and 53 acres of open deposit storage. The other large US Naval Advance Bases in Australia were at Naval Base Sydney and Naval Base Darwin. Unlink Darwin, Brisbane was out of the reach of Japanese bombers. Parts of Naval Base Brisbane began moving to more forward bases in January 1944. Palm Island base was moved on September 1, 1944, and Townsville moved in July 1944.
