By comparison, Goldman, the bank operating Apple Card in the U.S., has previously refused to perform that block future debits process for me; they simply didn’t have the capability. I ended up closing my account with them to stop the charges, which worked perfectly. I envy Australia’s apparent regulation to compel merchants to do so.
As an additional data point, in the UK I can just login to my banking app and remove the authorisation for a particular vendor (or, for people who don't use online banking, I could phone up to do the same thing).
