The Anzac spirit or Anzac legend is a concept which suggests that Australian and New Zealand soldiers possess shared characteristics, specifically the qualities those soldiers allegedly exemplified on the battlefields of World War I. These perceived qualities include endurance, courage, ingenuity, good humour, larrikinism, and mateship. According to this concept, the soldiers are perceived to have been innocent and fit, stoical and laconic, irreverent in the face of authority, naturally egalitarian and disdainful of British class differences.

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, tropical savannas in the north, and mountain ranges in the south-east.
