Digger

Digger: An Australian; also a New Zealander. The name originated for Australians in the old gold-mining days, at the "diggings," and for New Zealanders among the "gum-diggers." In the War, it applied both to Australians and New Zealanders, and considered a title of distinction in both cases. Australians specially claimed it for their trench work at Gallipoli, and New Zealanders for the work of the NZ Tunnelling Company on the Western Front. "Digger" in the War was a common term of greeting among Australian troops, equivalent to "chum" and eventually displacing "Cobber." It was often also heard among British troops in the same sense.
