For a limited time, CBA is waiving annual fee on all new credit cards (including all Awards cards) for the first year.
The the dual card Platinum Awards' usual annual fee is $250. You may earn 3 Awards points for every $1 spent with the Amex card and 1 point for every $1 on the Mastercard.
Haven't they had this "special" running for a while? I'm sure they had this in December.
