The importance of the Australian contribution to the Allied war effort during World War I should never be underestimated. Some 400,000 Australians volunteered for active duty, an astonishing 13 per cent of the entire (white) male population, a number so great that the Australian government was never forced to rely on conscription. Casualties were an astonishing 52 per cent of all those who served, ensuring that the effects of the war would be felt long after the armistice. In particular, their epic endeavour at Gallipoli in 1915 was the nation's founding legend, and the ANZACs went on to distinguish themselves both on the Western Front and in General Allenby's great cavalry campaign against the Turks in the Middle East. Their uniforms and insignia were also significantly different from those of the British Army and provide the basis for a unique set of artwork plates.

At the Front Line draws on a plethora of letters, diaries and documents written by over 300 Australian soldiers in the field to present a picture of the hardships and triumphs of their wartime experience. Mark Johnston analyses the suffering of front-line soldiers caused not only by the opposing force, but also by the conditions imposed by their own army. The book details the physical and psychological pressures of life at the front and shows how soldiers survived or surrendered to unbearable environments, fear, boredom and the constant threat of impending death. The myths of mateship and equanimity are brought under scrutiny. Much hostility can be explained by competition between ranks and the perceived hostility of superiors. The author investigates the immense strain that led to many breakdowns and the characteristic forebearance that saw so many others through.

This book recounts the organization and deployment of one of the most important fighting armies of World War II. Australian divisions made a large and distinctive contribution to victory both in the deserts of the Middle East and the jungles of the South-West Pacific,earning for the second time a unique reputation for aggressiveness, endurance and independence of spirit. The text is illustrated with original wartime photos from all fronts; and with full colour plates showing a wide range of uniforms and gear, together with the complex and colourful Australian system of unit insignia.

Uses the diaries and letters of a thousand Australian soldiers to reconstruct with great sensitivity the valour and the tragedy of their experience. Shows how and why the Great War was to have profound effects on the attitudes and ideals of Australia as a nation.

Sourced from Oppenheimer's own research and archival material from the Australian War Memorial, Australian Red Cross archives and State Libraries, Australian Women and War contains accounts of women such as Nursing Sister Nellie Gould in the Boer War and Angela Rhodes, the first Australian Military female air traffic controller to serve in Baghdad during the second Gulf War. The book also contains little known accounts of women such as Nurse Ethel Gillingham, one of the only Australian women to be a POW in WWI, and the group of Australian teachers sent to South Africa during the Boer War to work in the internment (concentration) camps.

Fighting The Enemy, first published in 2000, is about men with the job of killing each other. Based on the wartime writings of hundreds of Australian front-line soldiers during World War II, this powerful and resonant book contains many moving descriptions of high emotion and drama. Soldiers' interactions with their enemies are central to war and their attitudes to their adversaries are crucial to the way wars are fought. Yet few books look in detail at how enemies interpret each other. This book is an unprecedented and thorough examination of the way Australian combat soldiers interacted with troops from the four powers engaged in World War II: Germany, Italy, Vichy France and Japan. Each opponent has themes peculiar to it: the Italians were much ridiculed; the Germans were the most respected of enemies; the Vichy French were regarded with ambivalence; while the Japanese were the subject of much hostility, intensified by the real threat of occupation.
