I’m an existing Westpac customer and have the Black Mastercard. I also used to have the Westpac issued Amex until they cancelled it earlier this year. I’m trying to apply for the new Westpac Black AMEX for the 40.000 Qantas points signup bonus. During the application on the Westpac page I don’t seem to be able to just choose the Amex but have to apply for both Mastercard & Amex at the same time. How would I just apply for the Amex given I already have the Mastercard?
