The 6th Division was an infantry division of the Australian Army. It was raised briefly in 1917 during World War I, but was broken up to provide reinforcements before seeing action. It was not re-raised until the outbreak of World War II, when it was formed as a unit of the Second Australian Imperial Force (2nd AIF). Throughout 1940–41 it served in the North African Campaign, the Greek campaign, on Crete and in Syria, fighting against the Germans, Italians and Vichy French. In 1942, the division left the Middle East and returned to Australia to meet the threat of Japan's entry into the war. Part of the division garrisoned Ceylon for a short period of time, before the division was committed to the New Guinea campaign. In New Guinea, its component brigades had a major role in the successful counter-offensive along the Kokoda Track, at Buna–Gona and around Salamaua–Lae in 1942–43. Throughout late 1943–44, the division was re-organised in Australia before being committed as a complete formation to one of the last Australian operations of the war around Aitape–Wewak in 1944–45. History Formation The 6th Division was first formed in 1917 in Britain during World War I as part of an effort to expand the First Australian Imperial Force. Its existence was short-lived, though, and as a result of manpower shortages that occurred because of a failure to make good the heavy losses that the AIF had suffered on the Western Front in 1917, it was decided to disband the division and its subordinate units in September 1917 and use their personnel to reinforce other units. As a result, the division was broken-up as replacements several months later, before it saw action. The division was not re-raised during the interwar years and subsequently remained off the Australian Army's order of battle until World War II broke out. Due to the provisions of the Defence Act, which precluded the five existing Militia divisions from serving overseas, the government decided to raise an all-volunteer force known as the 2nd AIF. The 6th Division was the first division formed within the 2nd AIF, being raised on 28 September 1939. Initially under the command of Lieutenant General Thomas Blamey, upon formation the division consisted of the 16th, 17th and 18th Brigades, each established with four infantry battalions. Later, though, it was reorganised as a result of the 18th Brigade being sent to the United
