The 22nd Battalion was an infantry battalion of the Australian Army. It was raised in 1915 as part of the Australian Imperial Force for service during World War I and formed part of the 6th Brigade, attached to the 2nd Division. It fought during the Gallipoli campaign and on the Western Front before being disbanded in 1919. In 1921, it was re-raised as a part-time unit and was merged with the 29th Battalion in 1930 to form the "29th/22nd Infantry Battalion". Split in August 1939 and known as the "22nd Battalion (South Gippsland Regiment)", the battalion saw action against the Japanese during World War II in the Huon Peninsula and New Britain campaigns. The battalion was disbanded in June 1946. It was re-established as part of the Royal Victoria Regiment in the mid-1960s as a remote area battalion within the Citizens Military Force, and later became a part of the &lt;a href="8th/7th%20Battalion%2C%20Royal%20Victoria%20Regiment"&gt;8th/7th Battalion, Royal Victoria Regiment&lt;/a&gt;.
