Not only that. All of the big four were also unhappy with apple’s policy of not giving 3rd parties access to the nfc chip on iphones for payments because it prevents them from making their own wallet apps available to apple users. They held out of apple pay and fought against that policy for years, but finally lost the fight and relented and now support apple pay for their customers.Presumably They weren't happy with paying Apple a cut of each transaction through Apple Pay you could probably read the ACCC submission by Westpac to figure out more.
