Traditionally a colloquial term for the land of Australia.
A great place of diverse environments and people.
Does have a history of convict incarceration, as pointed out in other posts. However these convicts were for the most part men whom were unwilling to kneel to the oppressive English justice system and so were "swept" over to Australia. The results of which have been a nation of extremely hard men, who have developed a kickass culture of sportsmen and beer drinkers... in other words England chopped off its balls and sailed em to Oz. hehe

When you are a cool person from Australia then your home is down under

Down under AKA Australia, the greatest place on earth. Not to be confused with New Zealand although it could be classed as another Australian State.

A slang name for Australia, used by everyone except the citizens of said country. Kind of like how everyone calls New York the 'Big Apple'- except New Yorkers.

Term used to describe any cities, countries, etc, near the Australian Continent. Lower Asian countries may also be included to be "Downunda."

Note: The former definition was extremly rude so I changed it.

To eat pussy, another way to say snatch snacking or tongue tetherball
