On 10 September 1915, the British government sent a formal appeal to Canada, South Africa, Australia and New Zealand to raise tunnelling companies in the Dominions of the British Empire.
[1] In August 1915, the Australian geologist and Antarctic explorer Edgeworth David, after reading reports about mining operations and tunnelling during the Gallipoli Campaign, along with Professor Ernest Skeats, a professor at the University of Melbourne, had already written a proposal to George Pearce, the Australian Defence Minister, suggesting that the government raise a military force to undertake mining and tunnelling.
[2] After the proposal was accepted, David used his advocacy and organisational abilities to set up the Australian Mining Corps, and on 25 October 1915 he was appointed as a major, at the age of 57.
[3] The first contingent of the corps consisted of 1,300 officers and men that were initially organised into two battalions before being reorganised into the units listed below:[4] The first three of these units were tunnelling companies, while the Electrical Mechanical Boring and Mining Company was tasked with carrying out related repairs.
[1] The four mining units formed by the Royal Australian Engineers for the British Expeditionary Force departed Australia for the United Kingdom in February 1916,[5] became fully operational by March 1916,[1] and arrived on the Western Front in May 1916.
