I had missed the part where I'm only supposed to put in my "my share" of the expenses, and had listed the full amount (joint expenses) for each expense category. Because this was not an application for a joint card, I didn't need to list my partner's share of expenses. I wasn't aware of this! The helpful ANZ fellow had noticed that my bank statement was for a joint account, and that I had listed the full amount for rent, car expenses, etc, and he figured that I should probably only be listing half of that amount in my credit card application. So we went through every single expense category and he let me correct the number.
