Australian rules football
Football is the most popular sport in Australia, with crowd attendances of 50-80,000 people common to normal home and away matches and capacity crowds of 100,000 people at the home of football the MCG during the finals and special matches.  The record crowd still remains at 121,696, who watched that most history-making of all Grand Finals in 1970, between Carlton and Collingwood, where Carlton came from a 44-point deficit at half-time to win the game by implementing an entirely new system of play, handballing out of the backline, which changed the game forever, and marked the beginnings of the transition of the game from one of a 'territorial' base to 'possession football'.
