Another Aussie here, and I could maybe be interested. I typically carry at least 3 cards on me: credit card, AmEx, separate bank keycard / debit card, plus coffee loyalty cards. I can't always remember if a store takes AmEx (high Frequent Flyer point earnings), or if they do take AmEx but impose a 3% surcharge (negates the FF points benefit). It would be nice to have just one card, that automatically knows the best card to use at each store.
But without support for PayWave / PayPass / Chip & PIN, it's DOA in Australia. I want a card I can use when traveling to Europe as well (requires Chip & PIN). And Coin has a sleeker Uber-esque look to it as well - that rainbow on the Wallaby card doesn't exactly say "luxury" or "exclusive". (Not that it has to be, but it'd be nicer to drop a black / carbon card as an early adopter, not a plastic thingy called "wallaby" with a rainbow.)
