Australia willingly participated in World War I; many Australians regard the defeat of the Australian and New Zealand Army Corps (ANZACs) at Gallipoli as the birth of the nation — its first major military action. Much like Gallipoli, the Kokoda Track Campaign is regarded by many as a nation-defining battle from World War II.
The significance of the battle of Gallipoli is perhaps most strongly felt in Australia and New Zealand where it was the first great conflict experienced by those fledgling nations. Before Gallipoli the citizens of these countries were confident of the superiority of the British Empire and were proud and eager to offer their service. Gallipoli shook that confidence and three years on the Western Front would destroy it utterly.Source(s): www.wikipedia.org
