The cemetery was named after the 7th Australian Field Ambulance, which landed on Gallipoli in September 1915, but over 350 of the graves were brought in from earlier cemeteries after the Armistice (the majority of the casualties are therefore not Australian, but mainly 54th (East Anglian) Division). These smaller burial grounds were known as Bedford Ridge, West Ham Gully, Waldron's Point, Essex, Aghyl Dere, Eastern Mounted Brigade, Suffolk, Hampshire Lane Nos. 1 and 2, Australia Valley, 116th Essex, 1/8th Hants, Norfolk, Junction, and 1/4th Northants. There are now 640 Commonwealth servicemen of the First World War buried or commemorated in this cemetery. 276 of the burials are unidentified but special memorials commemorate 207 casualties known or believed to be buried among them.
