The 17th Battalion was an infantry battalion of the Australian Army. Although its numerical designation was bestowed upon it during World War I, the 17th Battalion can trace its lineage back to 1860, when a unit of the New South Wales Volunteer Rifles was raised in St Leonards, New South Wales. This unit has since been disbanded and reformed a number times. Through its links with the units of the colonial New South Wales defence force, the battalion's history includes service in the Sudan and South Africa. During World War I, the 17th Battalion was raised for overseas service as part of the Australian Imperial Force. Attached to the 5th Brigade, 2nd Division, the battalion was raised in 1915 and sent to Egypt initially, before taking part in the fighting at Gallipoli against the Turks. Later the battalion was sent to the Western Front in France and Belgium, where it served in the trenches as part of the Australian Corps. Throughout the course of the war, the battalion won numerous battle honours and its members received many individual awards, however, at the end of the war the battalion was disbanded in April 1919. In 1921, the battalion was reformed as a militia unit known as the 17th Battalion (North Sydney Regiment), before being disbanded in 1944. The battalion was reformed in 1948 as an amalgamated unit known as the 17th/18th Battalion (The North Shore Regiment), before being reduced to a company-sized element in the 2nd Battalion, Royal New South Wales Regiment in 1960. In 1965, the battalion was reformed again as the 17th Battalion, Royal New South Wales Regiment, before being amalgamated to form the 2nd/17th Battalion, Royal New South Wales Regiment in 1987. History Formation The battalion's origins began when the St Leonards Volunteer Rifles was raised in 1860 in the northern suburbs of Sydney as part of the military forces of the New South Wales colonial defence force. Members of this unit served overseas in 1885 in Sudan, and then again in South Africa during the Second Boer War. In 1903, following the Federation of Australia this unit became part of the Commonwealth Military Forces and was renamed the 1st Australian Infantry Regiment. In 1912, a system of compulsory military service was introduced and the unit was renamed the 18th Infantry, and then later, in 1914, the 17th Infantry. World War I When World War I began, due
