3rd Battalion (Australia) The 3rd Battalion was an infantry battalion of the Australian Army. Originally raised as part of the First Australian Imperial Force for service during World War I, the battalion formed part of the 1st Brigade, attached to the 1st Division. It was formed shortly after the war broke out and was among the first Australian units to be sent overseas, arriving in Egypt in December 1914. In April 1915 the battalion participated in the Landing at Anzac Cove, coming ashore in the second and third waves. In December 1915 the 3rd Battalion was evacuated from the Gallipoli peninsula and withdrawn to Egypt again, where it took part in the defence of the Suez Canal before being sent to France to fight on the Western Front in March 1916. For the next two and a half years the unit would serve in the trenches in France and Belgium and would take part in many of the major battles fought during that time. In May 1919, following the end of the war, the battalion was disbanded and its personnel repatriated back to Australia.
