The Hidden Costs of Credit Card Surcharges for Australian Merchants

Published 22 July 2026 · LocalPay Team

What You're Really Paying to Accept Cards

Credit card processing fees are rarely transparent. The headline rate your acquirer quotes — say, 1.5% — is just the beginning. Beneath that surface lie interchange fees (paid to the card-issuing bank), scheme fees (paid to Visa/Mastercard), assessment fees, cross-border markup (for international cards), and premium card surcharges (for rewards and corporate cards that cost 2-3x more to process).

The true blended cost for an Australian merchant accepting cards is typically 1.5% to 3.5% of every transaction. For a business processing AUD $500,000 annually, that's AUD $7,500 to $17,500 in fees — before accounting for chargeback losses.

The Surcharge Pushback Problem

Many merchants try to recover card fees by passing surcharges to customers. But Australian consumers increasingly resent card surcharges — and the ACCC has actively investigated excessive surcharging practices. Passing fees to customers damages brand perception and drives them toward competitors who offer surcharge-free payment options.

The Domestic Rail Alternative

• BPAY: Predictable flat-rate billing with no percentage-based interchange. Ideal for invoices and high-value transactions.
• PayID: Near-zero processing cost for instant transfers. Perfect for everyday checkout payments.
• PayTo: Low-cost recurring payment mandates that eliminate Direct Debit failure fees and chargebacks.

By shifting transaction volume from credit cards to domestic bank rails, Australian merchants can reduce their total payment processing costs by 60-80% while simultaneously eliminating chargeback exposure entirely.
