The Flag of Australia The Australian Aboriginal Flag The Flag of Torres Strait Islanders
Australia was discovered about 45,000 years ago when they either walked or made short sea-crossings from Papua to the north in what is now the Torres Strait. In Australia they grew into diverse cultures with around 250 languages spoken by nations such as the Koori, Murri, Noongar, Yamatji, Wangkai, Nunga, Anagu, Yapa, Yolngu and Palawah, who together may've numbered around 3 quarters of a million. 43,830 years later (give or take a few thousand) it was claimed, like a quarter of the planet, by the tiny, faraway island of Great Britain.
Initially, it served as a penal colony set up at Port Jackson on January 26, 1788, which is why it's Australia Day today. 50% of the indigenous population died from smallpox within the following years. Massacres and land seizures reduced the indigenous population another 30%. Often the convicts sent to Australia were charged with minor offenses. In the 1850s, the Gold Rush began and with it, an Americanization of the language. For example, "bonanza" (borrowed from Spanish) became "bonzer." By 1827, Australian English was already diverging significantly from British English. Author Peter Cunningham noted a distinct vocabulary and a non-rhotic accent that owed heavily to Cockney. It is typically divided into three accents which owe less to region than UK English or US English.
Broad: Exemplified by larrikins Paul “g’day mate” Hogan, Steve “crikey” Irwin.
General: The typical Australian of Cate Blanchett, Russell Crowe and Nicole Kidman.
Cultivated: The British-sounding manner of Geoffrey Rush or Judy Davis.
None of the examples above probably say "shrimp on the barbie" since "shrimp" are called "prawns" in Australia.
Most of the wildlife and plant life is endemic. It's the flattest country on Earth, mostly desert and covered with the least fertile soil. It seems like wherever you go in the world, you run into loads of Australians. Luckily, they all have multizone DVD players.
