I strongly agree with the move by the RBA to put a STOP on over charging on creditcard fees and the below link, which you need to copy and paste into your web browser, is an article from Courier mail ‘online’ which provides more info on this subject.

I certainly hate being charged $7.70 by one airline and also hate retailers who have fees but do not disclose it.
Good on you RBA
