The short answer

Australia's card surcharge reform removes the visible payment fee, but it does not remove the underlying cost of accepting payments.

From 1 October 2026, eftpos, Mastercard and Visa will generally impose no-surcharge rules on credit, debit and prepaid transactions. American Express and UnionPay are also removing surcharging, while PayPal's no-surcharge rule follows on 5 October 2026.

At the same time, the domestic consumer credit interchange cap is falling from 0.8% to 0.3%.

The result is a simpler customer-facing price, but a more demanding merchant operating environment. Businesses should not automatically absorb every cost or apply a broad price rise. They should first establish the effective cost of each payment method, confirm how interchange reductions flow through, enable least-cost routing and model whether all-in pricing or targeted discounts produce the best commercial outcome.

The next competitive advantage is not the ability to add a fee at checkout. It is the ability to see, measure and optimise payment cost across the entire business.

What is changing on 1 October?

The Reserve Bank of Australia has not directly imposed a new legal ban on merchants. Instead, the RBA is removing its prohibition on card-network “no-surcharge” rules. That enables the designated networks to impose rules preventing merchants from adding a card surcharge.

The practical result for most merchants is still clear: a customer paying $10 by card should generally pay $10, not $10 plus a card fee.

The first wave applies to:

1. eftpos debit and prepaid cards.

2. Mastercard credit, debit and prepaid cards.

3. Visa credit, debit and prepaid cards.

4. American Express and UnionPay transactions under their own network decisions.

5. PayPal transactions from 5 October 2026 under PayPal's own rules.

Weekend and public holiday surcharges, booking fees and service fees are separate categories and are not automatically affected by the card surcharge changes. Merchants should confirm the treatment of any exception with their PSP and review the latest network rules before making changes.

The RBA expects the reform to save consumers approximately $1.6 billion a year in surcharge payments and businesses approximately $200 million in surcharge fees. However, the cost of payment acceptance does not disappear. It moves into the merchant's pricing, margin, provider contract or payment-method strategy.

What is payment-cost visibility?

Payment-cost visibility is the ability to identify the full cost and commercial impact of every payment method, channel, card type and routing decision.

It goes beyond the headline merchant service fee. A useful view should include:

• interchange and scheme fees;

• acquirer and PSP margins;

• gateway and platform charges;

• terminal and software fees;

• fraud and dispute costs;

• refunds and chargebacks;

• currency conversion and cross-border costs;

• payment success rate and failed-payment recovery; and

• the margin and conversion impact of each payment option.

This distinction matters because lower interchange does not necessarily equal a proportionate reduction in the final merchant service fee. The RBA estimates that the interchange reforms will reduce payments flowing from businesses to banks by about $910 million a year, but interchange is only one component of the total acceptance cost.

Banks are already responding by repricing rewards programmes, annual fees and insurance benefits. Those changes may alter customer payment behaviour and card mix over time. Merchants therefore need to monitor both provider pricing and customer behaviour rather than treating 1 October as a one-off compliance event.

Why the reform makes routing more important

The surcharge previously made payment cost visible to the customer, even if imperfectly. Once that signal disappears, the merchant must create its own internal visibility.

Least-cost routing is one of the most direct levers. It sends eligible dual-network debit transactions through the lower-cost network, typically eftpos rather than an international debit scheme, subject to the merchant's configuration and provider arrangements.

The RBA reports that 83% of merchants have least-cost routing enabled for in-person payments, while online availability is approximately 98%. Availability, however, is not the same as effective enablement. Configuration varies by provider, terminal, channel and business location.

Merchants should ask:

1. Is least-cost routing enabled across every eligible terminal?

2. Is it available in online checkout flows?

3. Which transaction types are excluded?

4. Is routing based on a fixed rule, a threshold or a more dynamic decision?

5. What is the actual saving after provider fees and operational costs?

6. Does routing affect authorisation, payment success or customer experience?

This is also where payment orchestration becomes more valuable. Static rules may be sufficient for a simple single-channel merchant, but complex businesses need to evaluate cost, approval performance, issuer behaviour, geography, risk and settlement requirements together.

Quantum Payments' analysis of the $231 billion false-decline problem and AI fraud detection explores why routing should be treated as a control-plane capability rather than a fixed gateway cascade. The objective is not to choose the cheapest route at any cost. It is to choose the best route for the transaction while protecting conversion, resilience and compliance.

Should merchants use A2A or PayTo discounts?

Account-to-account payments remain a potential alternative, but they are not yet a universal replacement for cards. Global Payments data reported by the ABC indicates that A2A payments represented approximately 5% of Australian ecommerce transaction value and 3% of in-store transaction value in 2025.

That suggests adoption is growing from a relatively small base. Merchants should test A2A and PayTo discounts where they can create a genuine economic benefit, but avoid adding friction that reduces conversion.

A practical approach is to:

1. Make the preferred payment option easy to understand.

2. Show the discount before the customer commits.

3. Keep the number of checkout choices manageable.

4. Measure payment success and completion, not just the fee rate.

5. Reconcile settlement and refunds consistently across payment methods.

6. Review whether the discount is smaller than the cost saved.

A discount is not automatically better than a surcharge. It is better only when it improves the combined result across payment cost, conversion, average order value and customer lifetime value.

All-in pricing or method-specific discounts?

The RBA says merchants can reflect acceptance costs in overall pricing or use discounts to steer customers towards preferred payment methods.

The right model depends on the business.

All-in pricing can be effective when:

• customers compare prices across competitors;

• checkout simplicity is a priority;

• payment costs are relatively stable;

• products have sufficient margin to absorb variation; and

• the business wants one consistent price across channels.

Method-specific discounts may be useful when:

• A2A, PayTo or eftpos costs are materially lower;

• the business can communicate the saving clearly;

• payment methods are available across the relevant customer journey; and

• the discount does not create a confusing or fragmented checkout.

The wrong response is a broad price increase based on the old surcharge percentage. That risks passing through costs that may no longer exist after the interchange reduction, while failing to account for differences between debit, credit, foreign-issued, online and in-person transactions.

The implementation timetable

Merchants should treat the reform as a staged operating change:

• 1 October 2026: no-surcharge rules generally begin for eftpos, Mastercard and Visa. Domestic interchange caps are reduced.

• 5 October 2026: PayPal's no-surcharge rule takes effect.

• 30 October 2026: designated card networks and large acquirers begin publishing specified fee information.

• 30 January 2027: large acquirers begin publishing information on how interchange reductions have flowed through to merchant service fees.

• 1 April 2027: interchange caps apply to foreign-issued card transactions acquired in Australia, and more detailed merchant statements are required.

Foreign-issued card treatment deserves particular attention. Network rules may generally remove surcharging across eligible cards, but interchange treatment changes again from April 2027. Merchants should confirm the position for domestic and foreign-issued cards with their PSP.

Merchant checklist: what to do now

1. Disable surcharge logic and test terminals, POS, online gateways, invoices, receipts, subscriptions and payment links.

2. Remove outdated surcharge language from checkout screens, menus, quotes, customer emails and terms.

3. Audit effective cost by card type, channel, issuer, location and region.

4. Confirm how domestic and foreign-issued cards are treated by your PSP.

5. Check whether the new interchange caps are passed through to your plan.

6. Enable least-cost routing where appropriate and measure the result by terminal and channel.

7. Evaluate PayTo and A2A discounts without creating unnecessary checkout friction.

8. Model all-in pricing against method-specific discounts using real transaction and margin data.

9. Monitor conversion, payment success rate, average order value, refunds and gross margin.

10. Reconcile new statements and fee disclosures against your pre-October baseline.

11. Review provider contracts, pricing schedules, service inclusions and customer communications.

12. Ask your PSP how network-rule changes or exemptions will be communicated if the position changes.

Quantum Payments' business features are designed to connect payment acceptance, orchestration, omnichannel sales, accounting and operational intelligence in one environment. That unified view is increasingly important when the cost of a payment can no longer be managed as a visible checkout surcharge.

The strategic read

The surcharge reform is a pricing simplification for customers and a measurement challenge for merchants.

The visible fee is going away, but the underlying economics remain. Businesses that respond by applying a blanket price increase may protect revenue while losing competitiveness. Businesses that absorb everything may protect conversion while weakening margin.

The stronger strategy is evidence-led:

1. Establish a clean payment-cost baseline.

2. Separate interchange from the rest of the acceptance stack.

3. Confirm that savings are passed through.

4. Route eligible transactions intelligently.

5. Test A2A and PayTo incentives without damaging checkout flow.

6. Make pricing decisions using conversion, success rate, AOV and margin together.

Network rules and exemptions can change. Merchants should check their PSP for the latest implementation requirements and confirm how their specific terminals, gateway, contract and payment methods are affected.

The next payment-cost problem is not the surcharge. It is the cost that remains invisible after the surcharge disappears.

Frequently asked questions

Is the Australian card surcharge ban imposed directly by the RBA?

No. The RBA is removing its prohibition on no-surcharge rules. The card networks then impose their own rules on participating merchants and payment providers. The RBA does not directly regulate merchants in this process.

What is the domestic consumer credit interchange cap from 1 October 2026?

The cap falls from 0.8% to 0.3%. The effect on a merchant's total service fee depends on the provider's pricing model and the merchant's transaction mix.

Can merchants still offer payment-method discounts?

Yes. Merchants can generally offer discounts for preferred payment methods, subject to applicable pricing rules, network requirements and provider arrangements.

Does least-cost routing still matter after interchange reform?

Yes. Lower interchange does not remove the potential benefit of routing eligible debit transactions through a lower-cost network. Merchants should measure the actual result rather than assume enablement equals savings.

When do foreign-issued card caps and detailed statements begin?

The foreign-issued interchange caps and more detailed merchant statement requirements begin on 1 April 2027.
