Cards still have magstrips on them but I can't remember the last time one got used. Maybe a gas station.
Australia has just 6 banks. And they have a history of collaborating on things like this - since a fluid economy raises all boats, and fraud hurts them all. All Australian cards and point of sale systems support chips and taps. And have for nearly a decade.
Was? Most of the ones I use are still magstripe-based ("remove your card quickly"). Only occasionally it says "leave card inserted" which is where (I assume) it's talking to the chip.
But the chips are relatively flaky and often don't work. At least here (California) after three failed chip communication attempts, the terminal allows a magstripe swipe instead as a backup. Happens quite often.
Master card said they will start phasing out mag strip in 2024.
Soon enough tap/dip will be the only way.
