Second Sino-Japanese War Naval Base Brisbane was a major United States Navy base built in the early part of World War II at Brisbane, Queensland, Australia.

[1][2] 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.

By the end of the war the Brisbane submarine fleet had sunk 117 enemy ships, totaling 515,000 tons, and rescued many downed airmen.

The first departure was half the Seabees, to build Naval Base Milne Bay in New Guinea on May 23, 1943.

By March 1994 the base had 90,000 square feet of depot warehouse space and 53 acres of open deposit storage.

The center had classrooms, camp, mess hall, jetties, slipway, a mock ship, and workshops.

Royal Australian Air Force also had Radar Station at the base.
