Australian English
Australian English began in 1788 when the first British prisoners were sent away to Australia as punishment. For fifty years, Australia was one big prison. The Australian accent was heavily influenced by Cockney, as there were large numbers of working class Londoners who were transported to Australia for the crimes. Australian English still has Cockney phrases and expressions and is also distinctive because of the Aboriginal words that have come into the language-words like "kangaroo" and "boomerang".
New Zealand English
New Zealand English started in 1840, with the treaty between the British and the Maoris in New Zealand. This began the colonization of the two islands New Zealand English sounds very similar to Australian English, but uses more British words and expressions and has borrowed words from the Maoris, particularly for the names of flowers and trees.
