what does it matter if juventus decides to play in australia or not, even if it's for money? do you actually know how much we earn from these tours? juve's appearance fee alone if i am not mistaken (we tried to bring them to malaysia for this asia pacific tournament and was told the price) - is around 500 000 - 1 mil USD. and that's appearance fee alone, not inclusive of transport, accommodation etc. that's how much they earn per country, and there's also ticket sales to consider etc ... without these "useless" tournaments to these countries Juventus would have much less money. and less money would probably mean less transfers and more trouble for Juventus. everything's business and it's important, there's nothing wrong with that, that's how it's run. be thankful there are some countries, like Australia and its fans, who are willing to pay.
furthermore, meow brought up a good point ... no matter how ignorant a country is about italian football, even if there's one hardcore juve fan in that country, let him/her enjoy seeing juventus on their soil.. not everyone's lucky enough and don't take that away from them. and there are LOTS of italians in melbourne, and i mean a LOT, so it's not like they're totally clueless.
