Mafia slang, means that someone got 'whacked', meaning killed. Because Australia is 'down under', the same like when a person is after he passes away.

Get the Go to Australia mug.
a phrase that is yelled out when something awesome happens like your school's sports team winning a game

oprah yelled this out very enthusiastically on her show when she announced she was taking her entire audience to Australia as part of her final season, and it is just too funny to not use in daily speech. bonus points for copying her trill scream

it also draws from winning children saying they are going to disney world after an impressive victory, such as in the movie Balls Of Fury
bob: i cant believe it, we just won the regional soccer championship!!
bill: WE'RE GOING TO AUSTRALIA!!!
