FFS, it's just sport, if they cheered for Italy ahead of Australia doesn't mean they hate anything.
You're also generalising - not everyone cheering for Italy cheered for them ahead of Australia, and even if they did, its a free country, they can do what they like. You make it sound like they should be locked up for cheering for Australia ahead of Italy - what about all the people that can't stand the game, and wouldn't watch it if it was the last thing on TV, are they ungrateful too?
You know, the World Cup has been around for a long time without Australia in it, so most people support or follow the country of their heritage.
You're probably one of those idiots that abuses people everytime they're wearing an Italian jersey post 2006. Give it a rest, you're embarrassing yourself.
Why do you support Spain?
