By May 1942, the Japanese Empire had seized control of much of the western Pacific Basin, including key British strongholds such as Hong Kong, Malaya, Borneo, and Singapore. With rapid and aggressive expansion, Japan aimed to capture Port Moresby in Papua New Guinea and neutralise Allied military assets in northern Australia. Following two decisive victories in the Philippines, Japan appeared poised for further success.
In the world’s first naval battle fought entirely by aircraft launched from carriers, U.S. forces—supported by an Australian surface action group—successfully repelled the Japanese advance. This pivotal engagement, known as the Battle of the Coral Sea, effectively safeguarded Port Moresby and shielded Australia from potential future attacks.
Each year, the Australian American Association (AAA) commemorates the enduring mateship forged between Americans and Australians during the battle. A solemn ceremony is held at the Australian–American Memorial in Canberra to honour this shared history. You can view a powerful video produced by Defence Australia to mark the 80th anniversary of the Battle of the Coral Sea.
