1st Division (Australia). The 1st Division is the oldest and longest-serving formation of the Australian Army. Formed in 1914 as part of the First Australian Imperial Force for service in World War I, it fought with distinction at major battles including Gallipoli, the Somme, and Passchendaele. It was re-raised for World War II, serving in North Africa and the New Guinea campaign, and remains a key deployable headquarters within the modern Australian Defence Force.

History

The division was established in August 1914 at Broadmeadows under the command of Major General William Bridges. As the foundation division of the Australian Imperial Force, it embarked for Egypt in late 1914, where it underwent initial training before its first major combat deployment to the Gallipoli Campaign in April 1915. Following the evacuation from Gallipoli, the division was reconstituted in Egypt and transferred to the Western Front in 1916, where it became part of the Australian Corps under the overall command of General John Monash. It was disbanded after the war in 1919, but was re-formed as part of the Citizen Military Forces in 1921. Mobilised again at the outbreak of World War II, the division saw action in the Siege of Tobruk and the First Battle of El Alamein before returning to Australia in 1942 to counter the Japanese advance. It fought in the Finisterre Range campaign and other operations in New Guinea before its final disbandment in 1945. The division was re-established in 1960 as a integrated regular and reserve command and is now headquartered at Gallipoli Barracks in Brisbane.

Structure

During World War I, the division's core consisted of three brigades: the 1st, 2nd, and 3rd Brigades, each comprising four infantry battalions raised from various Australian states. Its organic support included the 1st Division Artillery, engineer field companies, and signals units. In World War II, its structure evolved, incorporating brigades like the 16th, 18th, and 25th Brigades, along with dedicated artillery, engineer, and signals regiments. The modern 1st Division functions primarily as a deployable headquarters under Forces Command, responsible for generating and commanding Army forces on operations, with various combat, combat support, and combat service support units under its operational control for specific missions.

Commanders

Notable commanders of the division include its first, Major General William Bridges, who was mortally wounded at Gallipoli. He was succeeded by Major General Harry Chauvel, who later commanded the Desert Mounted Corps. During the latter part of World War I, it was commanded by Major General Talbot Hobbs, a prominent artillery officer. Other significant commanders include Major General James Legge, who led the division in 1915, and Major General Leslie Morshead, who commanded during the Siege of Tobruk. In the post-war era, command has been held by senior officers such as Major General John Caligari and Major General Paul McLachlan.

Campaigns and battles

The division's first major campaign was the Gallipoli Campaign, where it landed at Anzac Cove on 25 April 1915 and fought in battles such as Lone Pine and the Sari Bair offensive. On the Western Front, it participated in the bloody Battle of Pozières, the Battle of Bullecourt, the Third Battle of Ypres, and the Hundred Days Offensive at Amiens and the Hindenburg Line. In World War II, it fought in the North African campaign, notably during the Siege of Tobruk and at El Alamein. After returning to the Pacific theatre, it engaged in arduous jungle warfare during the Finisterre Range campaign, including the pivotal Battle of Shaggy Ridge.

Legacy

The 1st Division is a foundational institution of the Australian Army, its history deeply intertwined with the national narrative of World War I and the development of the Anzac spirit. Its battle honours are commemorated at the Australian War Memorial and its legacy is upheld by its continued service. The division's distinctive colour patch, a rectangle of grey over red, is one of the most recognised symbols of Australian military service. It remains the Australian Army's primary operational-level headquarters, a testament to its enduring role in the nation's defence from the First Australian Imperial Force to contemporary deployments.
