Australia is one of the most culturally diverse nations in the world. Within a population of over 25 million people (2020), over 400 languages are spoken, with English as the common and official language. Over a quarter of the population was born in another country. The story of Australia's growth as a modern country in the twentieth century is closely tied to those stories of the nearly 7 million migrants who have travelled from across the globe since World War II (1939-45) to make Australia their new home.
