Be careful if you pay an ANZ card by BPay. I set up my BPay a long time ago, and didn't change the number when the card got changed (I had the number set to my card number, not my account number). Up until now, the payment has gone through OK, but apparently something got changed. My payment towards my card disappeared into a black region- it hasn't gone onto my card (thus incurring fees) and it hasn't gone back to the sending bank. While I'm sure it will all get fixed in good time, it was a lot of unnecessary time spent in two banks trying to work it out. Check out your BPay details (and any recent payments).
I had the same thing happen with an account with Telstra. I had BPay setup for Internet account A, we moved and setup account b and I still paid account A which worked for several years until it didn't. Telstra was able to find it after a couple of weeks...
