Apple Wallet for Australians?

I’d like to add flybuys to my wallet. I’ve seen things online saying it’s compatible, then I saw that there was a separate app that I had to download to do it, which I’m not interested in doing. I just want everything to work in Apple Wallet, because that’s the reason it was made. Now I know theres company’s resisting Apple Wallet, like the idiots at CommBank, which unfortunately I bank with. I don’t see why for a technology that was introduced so long ago, Australians barely have any compatability especially for rewards cards, flybuys, eb world, Woolworths etc.

I think if Apple put more work into educating company’s to completely migrate to Apple Wallet, would actually complete their whole initiative to begin with. Company’s could save so much money on physical cards and finally get rid of the wallet. Imagine Drivers licenses, every rewards card from RSL clubs to that local cafe.
