Seems like the Aussies are getting into the soccer culture:
"A flare was let off by a member of the crowd and landed on the roof of a building adjacent to the stage.
As fans began to make their way out of the area one man yelled "let's start a riot"."

I never understood the idea of some "fans" to declare nuclear war on their own city if they win or lose a sports match.
All these red cards and yellow cards and rioting fans and diving Italians and yet no chick pics. Have they been red carded too? If so then the refs HAVE gone too far!!
