Just fyi - for BankDirect referral miles to post --

* The email address receiving the referral needs to be the same address the new account applicant uses for the account.

* The applicant needs to list the name and address of the person providing the referral. Note that the email address must be the one that the existing accountholder has on file with BankDirect.

In other words, don't refer or list as referrer a 'Flyertalk address' if you use a different email address for your banking.
