Australians pay about $1.8 billion a year in card surcharges, and from October 1 most of it becomes illegal. The Reserve Bank of Australia's ban on debit and credit card surcharging takes effect that day, and the mechanics of the reform are settled: businesses must switch off surcharging on their terminals by September 30, remove the signage, and fold whatever card acceptance costs remain into their posted prices. The part that is still moving is the money itself. It does not vanish on October 1. It changes hands, and the first hand reaching out for it belongs to the banks.
The RBA paired the surcharge ban with the sharpest cut to interchange fees in the modern history of Australian payments. Interchange is the fee paid between banks on every card transaction, and it is the raw material from which card rewards programs are built. From October 1, the cap on consumer credit card interchange falls from 0.8 percent to 0.3 percent, and debit interchange falls to 0.16 percent or 8 cents, whichever is lower. Foreign-issued cards get a 1 percent cap from April 2027. The RBA estimates the cut costs banks more than $660 million a year and saves businesses about $910 million. The surcharge ban itself moves roughly $1.6 billion of the $1.8 billion Australians were paying in surcharges off the consumer side of the ledger.
So the reform has a tidy public arithmetic: consumers stop paying surcharges, businesses stop collecting them, and banks lose interchange income to make the merchants whole. What the arithmetic hides is the third ledger entry, the one the banks have been quietly writing since the details of the ban became clear in early September.
The rewards clawback is already priced
In the weeks before the ban was even live, the banks began repricing their card books. St George lifted the purchase rate on its Amplify Qantas Platinum card from 20.99 percent to 23.99 percent and raised the annual fee from $75 to $125. NAB increased credit card interest rates by 1.5 percentage points. Westpac and St George raised the number of points required for gift card redemptions by 25 to 47 percent. Commonwealth Bank overhauled its rewards program, a repricing cycle Nine News has tracked against the October deadline. None of these moves is coincidental timing. Rewards programs are funded by interchange revenue, and interchange revenue has just been capped at roughly a third of its former level on credit.
The pattern is not unique to Australia. It is the standard response every time interchange gets cut by regulation: the card issuers stop bidding for spending, and the first thing they stop bidding with is the rewards currency. Consumers who hold premium rewards cards, the segment that generates the most interchange per transaction, are the natural place to recover the loss, because they are the segment least likely to leave over a fee or a rate increase. A customer who carries a Qantas Platinum card for the points is not going to switch to a no-frills card over 300 basis points of purchase rate if they pay the card off each month. That customer is exactly who the banks need.
The arithmetic of the reform therefore lands unevenly. A consumer who never used a rewards card and occasionally paid a surcharge at a cafe gains the whole value of the ban. A consumer who runs every expense through a premium rewards card and never paid a surcharge, because the merchants they use absorbed the cost, loses twice: the interchange that funded their points is gone, and the issuer now charges them more for the privilege of earning fewer of them.
The merchant side is not a pure win either
The ban also changes what businesses are allowed to do with their prices, and the Australian Competition and Consumer Commission has drawn the boundary in advance. Businesses can build card costs into their general prices. They cannot rebadge the surcharge as a service fee, a booking fee, or anything else that achieves the same thing, and the ACCC has said it will treat disguised surcharges and drip pricing as misleading conduct under the Australian Consumer Law. SmartCompany's preparation guide walks through the compliant and non-compliant versions of the same repricing decision. A cafe that lifts every price by 1.5 percent is compliant. A cafe that keeps prices flat and adds a 1.5 percent "payment service fee" at the till is not.
That distinction matters more than it looks, because only about 16 percent of Australian businesses currently surcharge, which means the overwhelming majority were already absorbing card costs into prices. For them the ban changes nothing visible. The businesses that do surcharge are concentrated in small-margin sectors, hospitality, retail, and fuel, and they are the ones with the least bargaining power over their payment providers. Their card costs will rise toward the posted price, and their customers will see it. The RBA's own framing concedes the point: the reform saves consumers money on surcharges, but nothing in it caps the price of a coffee.
What the RBA was actually fixing
The ban exists because surcharging stopped working the way it was designed to. The RBA's March 2026 review concluded that surcharge rules had become too complex, that surcharges were often poorly disclosed, and that consumers could not realistically avoid them in an economy where roughly three quarters of transactions are cashless. A JWS Research survey found about 76 percent of consumers wanted surcharging to stop. The policy problem was not that merchants were collecting too much. It was that a pricing mechanism built for a card-present, cash-heavy economy had become a mandatory toll in a card-default one.
The fix the RBA chose is to kill the toll and cut the toll road's funding at the same time, which is why the reform reads as two reforms: a consumer ban and an industry repricing. Payment networks will also have to publish their fees, on the theory that transparent scheme fees do more for merchant bargaining power than a regulated surcharge ever did.
The likely losers are hiding in the fine print
The clearest losers of the transition are being defined not by the RBA but by the card issuers' product sheets. Rewards holders will earn points at the old rates only until their programs repoint, redeem existing points under old schedules only until those schedules change, and enjoy interest-free periods only as long as their issuer keeps them. Consumer groups are already telling cardholders to redeem points before September 30, on the reasonable assumption that points will be worth less after the interchange cut flows through. That advice is probably correct and slightly ironic: the last thing the ban was supposed to do was accelerate redemptions.
The deeper question is whether the ban marks the start of the decline of the premium card as an Australian institution. The rewards card exists because interchange made spending on it worth bidding for. With credit interchange at 0.3 percent, the bid shrinks to roughly what it costs to service the account. Cards will still exist. The Qantas Platinum as a machine for arbitraging the interchange system will not, in anything like its current form.
Who actually wins
The honest winners are the unglamorous majority: the consumers who tap a debit card and occasionally got stung by a surcharge they did not notice until the receipt. The RBA estimates the reform returns about $1.6 billion a year to them. The banks lose interchange but keep the customer relationships that let them recover elsewhere, and the first recovery moves are already visible in card fees, rates, and points. The merchants gain the most direct benefit, roughly $910 million in lower payment costs, and keep the discretion to set their own prices.
The reform's real legacy may be simpler than any of that. Australia just ran the clearest natural experiment in card pricing anywhere: ban the surcharge, cut the interchange, and watch where the money goes. Every other country with a surcharging regime, and every regulator watching interchange, will read the result. The early returns say the cost does not disappear when you ban the toll. It finds a new route to the same destination, and this time the toll road's owners get to choose who rides for free.
The boundaries the ban leaves standing
The ban is narrower than its headlines. Cash payments are untouched, which matters in an economy where cash still carries legal tender status and a minority of transactions. Taxi fares sit outside the ban's reach. Businesses may still offer cash discounts, and the RBA's framework has always treated a lower cash price as a discount rather than a surcharge, a distinction the ban preserves. Weekend and public holiday surcharges and genuine booking fees remain lawful where they are unrelated to the cost of card acceptance, and businesses can still set card minimums.
Each of these boundaries is a place where money can migrate, and the ACCC's early warnings are aimed at exactly that migration. A restaurant that surcharged 1.2 percent on cards can lawfully raise its weekend prices and call it a weekend surcharge, because the weekend surcharge is not tied to the payment method. The honest price rise is lawful; the disguised one is not, and the line between them will be drawn by enforcement cases that have not yet been brought.
The boundaries also protect the businesses the ban hits hardest. A small merchant that genuinely cannot absorb card costs and cannot raise prices without losing trade keeps the cash discount and the weekend surcharge as escape valves. The RBA's design accepts that the ban will push some costs into general prices and simply requires the pushing to be visible. What the design does not do is tell anyone what the visible price should be. That is left to competition, which is the quiet acknowledgment at the center of the whole reform: the surcharge was never the only way card costs reached consumers, only the most legible one, and the RBA has traded legibility for honesty.
