The 2/7th Battalion was an infantry battalion of the Australian Army raised for service during World War II. Formed as part of the 6th Division shortly after the outbreak of the war as part of the all-volunteer Second Australian Imperial Force, the 2/7th Battalion's initial personnel were recruited primarily from the state of Victoria, although later reinforcements were drawn from most other Australian states. Basic training was completed in Australia, after which the battalion embarked for the Middle East as part of the first batch of Australian troops to deploy overseas. Further training was undertaken in Palestine before the battalion went into action against the Italians in January 1941. After participating in the successful capture of Bardia and Tobruk, it was committed to the disastrous Battles of Greece and Crete, where the battalion was essentially destroyed after the majority of its personnel were captured.

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. 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.
