We have some crossover banks here in NZ.
I’ve answered similar before, HERE
basically
Westpac did have a smart tag that was a viable conversion.
I think they stopped doing them in NZ, but you might want to confirm with OZ Westpac.
I personally had an ASB conversion done.
It was fantastic.
A really awesome option.
Unfortunately ASB no longer do these anymore.
but heres my writeup
There were a couple of other options, but as tap to pay on phones are more prevalent. its more difficult to find “pay tag” type style cards (generally an easy conversion)
personally for me, I only have my Crypto.com card as an CoM conversion option.
Some onfo here
Fidesmo indicated they may be expanding to Australia, but im not sure where that is at currently.
if it happens, there may be an option for you.
keep an eye out for Banks offering things like payment stickers, fobs, keyrings, wristbands etc.
generally good options for conversions.
Also check out travel credit cards, you might get lucky.
Outside of that, im keeping an eye on Swatch Pay and a few others to come downunder.
Ill be letting people know when something pops up in our neck of the woods.
in the meantime, ask your mates to see their credit cards and look for the telltale indicators for a CoM conversion

I know its overwhelming, but any questions, just ask.
