The document summarizes Australia's involvement in the Korean War from 1950 to 1953. It notes that when North Korea invaded South Korea in 1950, Australia was the first nation to support the UN in responding militarily. Australian troops fought under General MacArthur along the 38th parallel border. By the 1953 ceasefire, around 300 Australian soldiers had been killed, demonstrating Australia's commitment to opposing the spread of communism in Asia and its loyalty to the United States.
