I got my Card last week (as quite a few people did).
I have existing Westpac Accounts (Cheque, Savings, Mortgage, Normal CC) but the Airpoints Credit Card didn't show up online. I rang them up and it took longer to verify who I was to get them to make my New Airpoints Westpac Card to show up on Internet/Mobile Banking.
I should have the secondary card (For Wife) on Monday (Got Letter today about it).
I'm all ready to start spending Tomorrow :-)
