Something that is amazing about Sydney’s system though is that as a visitor to Sydney you can likely use the train system without needing an app or any sign up. Just use your credit or debit card via nfc on your phone (or the physical one)

I was honestly so impressed by that, you mean I can just tap on? Don’t need to stand here outside the gates for 10 minutes entering my info into a frustrating app? Don’t need to buy a $10 card, only $5 of which I’ll ever use? Even with suica being pretty easy to set up on iPhone, this is definitely something Sydney’s got over Japan’s system.

I’ve never noticed any delay on the London underground with Apple Pay or a normally debit card - certainly not a second. Havent used an oyster for years but I don’t remember it being faster.
