Australians love sports, and there is a wide variety of codes, primarily AFL (Australian Footbal League, aka footy), ARL (Australian Rugby League, aka league) or real mans rugby, Rugby Union, a more inernational game.
We also have a big soccer following too.
AFL has the tall skinny blokes stepping on each others back, rugby's two codes (league and union) have the big bulky blokes crashing into each other, and soccer has the brazilians pretending to be hurt.
Hope that helps reduce the confusion a bit :P
