There's been a recent change in Australia, the Reserve Bank put a cap on the maximum interchange fee credit card companies can charge in Australia (capped at 0.8%). As a result, many of the cards that earned the best rewards have been scrapped. I had an AmEx card that was good for earning airline points, the bank cancelled the card after the Reserve Bank ruling.
