Apologies for the poor website link! I actually saw this in the newspaper.
You must open the accounts in a branch.
Extra conditions:
Use your card five times before 31 March and if you are in the first 10,000 qualifying customers you will get the $50.
Oh and you will also get a chance to win a trip to meet the Australian cricket team in the West Indies…meh
Yeh I was about to say this is usually for new customers only.
