As aianus said, credit cards can easily be free! (pretty sure merchants are the ones who pick up the bill for that privilege) You are right that the international transfer of bitcoin is very useful - but to say there are no commission or fees is not true. If you start with Australian dollars and you want BTC, you pay fees and commission when you buy/sell BTC. Then you pay mining fees (if you want to support the ideals of BTC), and then to transfer back into Euros you would pay fees/commission with whatever exchange you're using. Granted, it is going to equate to less than the % you would pay if you did it with your bank. However I still feel having a fixed exchange rate is worth something.
