ANZ might make exceptions for high-end expats, but for others they are cold-shoulder disinterested, IMO. For no particular reason they have recently repeatedly 'encouraged' me to close my account, which was established when an earlier company established their retail branch. After that it was acquired by another company, and then it was sold to them. I was one of the very original customers (first 150), and due to guanxi was listed as their 'staff' in their system because I taught English at the company that set the branch up.
It's a good thing I kept it, because when I recently had a US$4000 check to deposit (not cash, mind you), my other bank (Fubon) rejected it, saying it was too big (seriously?!). But ANZ took it, earning a very pretty 30 day float on it, I might add.
So, I doubt ANZ is begging anyone to sign up.
