The Colony of New South Wales was established by the Kingdom of Great Britain in 1788, with the arrival of the First Fleet, and five other colonies were established in the early 19th century, now forming the six present-day Australian states. Large-scale immigration occurred after the First and Second World Wars, with many post-World War II migrants coming from Southern and Eastern Europe introducing a variety of elements. Immigration from the Middle East, south and east Asia, Pacific Islands, Africa, and Latin America has also been having an impact.
