 With the move of the majority of the AIF to France , the base organisation was transferred to the United Kingdom . Most of the training units moved to the Salisbury Plain , establishing depots at Perham Down , Rollestone , Larkhill and Tidworth . When it arrived , the 3rd Division also moved into camps in this area . Command Depots , where men returning from hospitals were sent before being returned to their units , were established at Perham Down , Weymouth , Wool , Dorset and Worgret . Depots for men moving from the United Kingdom to France were established at Étaples . In June 1917 , these were swapped with the Canadians for depots around Le Havre , thereby reducing travelling time from the Salisbury Plain . AIF Headquarters was established at Horseferry Road in London and Colonel R. M. McC . Anderson , a businessman , was appointed as its commandant . Anderson negotiated a new method of payment for services provided by the British Army as a per capita per diem payment .
