The 17th Brigade was an infantry brigade in the Australian Army. First raised in 1912 as a Militia formation to provide training under the compulsory training scheme, the brigade was later re-raised as part of the First Australian Imperial Force during World War I. Established in 1917 in the United Kingdom, it was broken up and disbanded without seeing action, and its personnel used as reinforcements for other formations. Reformed during World War II, it took part in fighting in Libya, Greece, Crete, Syria in 1941–1942. Following Japan's entry into the war, the Australian government pressed for the 6th Division's return, and the 17th Brigade was subsequently brought back from the Middle East, via Ceylon where they undertook defensive duties until July 1942. Following the brigade's return to Australia, it was deployed to New Guinea for two campaigns: the Salamaua–Lae campaign in 1943 and the Aitape–Wewak campaign in 1944–1945. After the war, the brigade was disbanded in January 1946. Today, its name is perpetuated by the 17th Sustainment Brigade, which was raised as a logistics formation in May 2006.

The Syria–Lebanon campaign, also known as Operation Exporter, was the invasion of Syria and Lebanon in June and July 1941 by British Empire forces, during the Second World War.
