Australia

Australian-rules football (a form of rugby) may be uniquely Aussie, but that doesn't mean the beautiful game takes a backseat to it. The national team routinely attracts record TV audiences, helped along by the fact that the squad has experienced unprecedented success in recent years. There's also a domestic league for both men and women.

A recent survey showed that the sport has a higher participation rate than any other in the country, with nearly a million people who say they play the game competitively.
