Plans for the formation began in November 1914 while the first contingent of Australian and New Zealand troops were still in convoy bound for, as they thought, Europe.However, following the experiences of the Canadian Expeditionary Force encamped on Salisbury Plain, where there was a shortage of accommodation and equipment, it was decided not to subject the Australians and New Zealanders to the English winter, and so they were diverted to Egypt for training before moving on to the Western Front in France.[4] Shortly afterwards it was officially adopted as the codename for the corps, but it did not enter common usage amongst the troops until after the Gallipoli landings.[15] Then in March 1916, the ANZAC Mounted Division with three Australian and one New Zealand brigade, was formed for service in Egypt and Palestine.[25] During World War II, the Australian I Corps HQ moved to Greece in March 1941 (Operation Lustre).[27] Some troops evacuated to Alexandria, but the majority were sent to the Greek island of Crete to reinforce its garrison against an expected German invasion from air and sea.[28] Others who were captured and transported to Axis POW camps in mainland Europe were able to escape en route via Yugoslavia.[31] The ANZAC Battle Group was the official designation of Australian and New Zealand units deployed to Timor Leste as part of Operation Astute.[13] This use is reflected in ANZAC Day, which commemorates both the Gallipoli landings specifically and all Australian and New Zealand soldiers that have served or died in wars more broadly.[33] In Australia, the term cannot be protected as a trademark or design, nor used in trade, business or entertainment or as the name of any boat, residence or vehicle.
