The 2nd Battalion was an infantry battalion of the Australian Army. It was initially raised for service during the First World War as part the Australian Imperial Force and saw action at Gallipoli before being sent to the Western Front in mid-1916, where it spent the next two-and-a-half years taking part in the fighting in the trenches of France and Belgium. Following the conclusion of hostilities, the battalion was disbanded in early 1919 as part of the demobilisation process.
