Origins of the Cold War
Australia's entry into the Cold War came in 1950, when it rushed combat air and sea forces into the Korean War, two days after the Americans did. The Australian Prime Minister received a hero's welcome in Washington. The ANZUS military alliance with New Zealand and the United States was signed in July 1951; it was a plan for consultation and did not involve military planning like NATO. Public opinion in Australia was intensely hostile to Japan after its wartime atrocities, but Japan was now an ally in the Cold War, so Australia's accepted the very generous soft peace treaty with Japan in 1951. Instead of worrying about a resurgent Japan, Australia now worried more about a possible Chinese threat.
Fort Lytton
Over 17,000 Australians served in the Korean War between 1950 and 1953. Fort Lytton’s signal station provided essential communications between Australian and its forces in Korea. The signal station was significantly upgraded at this stage, including upgrades to radio equipment, masts and aerials (antennas).
