From summary:
In short:
The RBA will remove surcharges on debit and credit cards, saving consumers and businesses about $1.8 billion each year.
The package of reforms also includes lowering the caps on interchange fees paid by Australian businesses, with a focus on small businesses currently paying the highest fees.
What’s next?
Most of the reforms are due to take effect from October this year.



LOL what? This is some a-grade bullshit.
In the before times, there were no “surcharges”. If the price on the menu was $10 then the charge on your card was $10.
Then Tyro appeared and said to cafes and restaurants, we can add our fees on top of the charge. So the price is $10 but the customer pays $10.15.
IMO, Tyro instigated the practice of surcharging.
