At the end of 1918, the Australian Army Medical Corps (AAMC) was a different organisation from the one that had existed when war was declared in 1914. Commencing the war with a regular staff of four officers, the AAMC rapidly expanded and developed. Almost entirely dependent on assistance from Britain and the Royal Army Medical Corps (RAMC) during the Gallipoli campaign in 1915, the AAMC, during the remaining years of the war, became more independent, developed its own practices and procedures, and asserted its expertise in order to have Australian medical control of Australian casualties.
