Aaronknight You've built a great-looking store, added your products, and started driving traffic. But without a reliable payment gateway integrated correctly, none of that effort translates into revenue. Customers who reach checkout and don't trust the payment process — or encounter friction — leave. Often permanently.
Choosing the right payment gateway for your Australian ecommerce store is one of the most consequential technical decisions you'll make. The wrong choice costs you in transaction fees, abandoned carts, and lost international sales. The right choice is largely invisible — customers pay, funds reach your account, and the process just works.
This guide compares the leading payment gateways available to Australian businesses in 2026 — fees, features, integration, and which types of stores each suits best.
A payment gateway is the technology that securely captures and transmits payment information between your customer's browser and your bank or payment processor. When a customer enters their card details at checkout, the gateway encrypts that data, verifies the transaction, and either approves or declines the payment — all in a matter of seconds.
Without a payment gateway, you have no way to accept online payments securely. Without the right payment gateway, you'll pay more in fees than necessary, lose sales to a poor checkout experience, or miss out on payment methods your customers expect.
Before comparing specific providers, it's worth understanding what actually matters when evaluating options within the broader Australian payment system:
Transaction fees — Most gateways charge a percentage of each transaction plus a fixed fee. The difference between 1.75% and 3.5% sounds small but compounds significantly at volume. A store processing $50,000 per month pays $875 at 1.75% versus $1,750 at 3.5% — an $875 monthly difference.
Accepted payment methods — At minimum: Visa, Mastercard, and AMEX. Increasingly important: Apple Pay, Google Pay, and Buy Now Pay Later options like Afterpay and Zip, which are widely used by Australian consumers. Good gateway services in Australia must also adhere to Australian Consumer Law and may integrate with local payment systems like NPP.
Platform compatibility — Does it support a smooth integration process with Shopify, WooCommerce, Magento, or whichever platform your store runs on? Look for strong software integrations that enable seamless integration with minimal technical effort, because poor setup creates checkout friction that costs you conversions.
Security & fraud protection — Providers should be pci dss compliant and have strong security measures. Real-time fraud detection and chargeback management tools still vary significantly between providers.
International transactions — If you're selling to customers outside Australia, assess a gateway's currency-handling capabilities, including support for multiple currencies, international payments, international transfers, and the fees tied to currency conversions.
Customer support — When something goes wrong at checkout, you need support that responds quickly. For an australian business, local support can reduce downtime during issues, and provider quality here varies enormously.
Stripe has become the default choice for most Australian ecommerce developers — and for good reason. It offers best-in-class documentation, clean API design, and genuinely excellent integration with every major ecommerce platform.
Fees: 1.7% + 30¢ per domestic transaction (Visa/Mastercard). International cards attract an additional 1.5% surcharge.
Key features:
Best for: Most Australian ecommerce stores — particularly those on Shopify or WooCommerce, stores with international customers, and businesses that want a set-and-forget solution with strong developer support.
Worth noting: Stripe's pricing is slightly higher than some domestic alternatives for purely domestic transaction volumes. At scale, this difference adds up.
One of Australia's most established payment gateways, eWay has been operating in Australia since 1998 and is trusted by tens of thousands of local businesses. Its brand recognition provides a trust signal to Australian shoppers who recognise the logo at checkout.
Fees: Pricing is quote-based depending on transaction volume, with eWay charging 1.9% + 20c per transaction as a reference point and typically remaining competitive for higher-volume merchants. Check monthly fees, set-up fees, additional fees, extra fees, and hidden fees before signing.
Key features:
Best for: Australian businesses that want a locally-trusted brand at checkout, particularly those with significant domestic transaction volumes and recurring billing requirements, including high-volume merchants that may benefit from volume pricing or pay monthly pricing plans.
Worth noting: Fraud prevention tools aren't enabled by default and require manual configuration — worth addressing immediately after setup.
Square is more than a payment gateway — it's an integrated payments ecosystem covering online, in-store, and mobile transactions. For businesses with both a physical presence and an online store, Square's unified platform simplifies reporting across cash flow and broader financial operations.
Fees: 1.9% per domestic online transaction. International cards attract higher rates.
Key features:
Best for: Businesses with both a physical store and an online presence that want a single payments ecosystem. Hospitality, retail, and service businesses work particularly well.
Worth noting: Square's breadth of features makes it more than most pure-play ecommerce startups need. If you're online-only and starting out, simpler options may serve you better initially.
PayPal remains one of the most recognised payment brands in the world — and that brand recognition has a measurable impact on conversion rates, particularly for customers who are hesitant to enter card details on an unfamiliar site. In Australia, supporting digital wallets also matters at checkout, and with 54.45% of Australians using iOS, demand for Apple Pay is easy to understand. Offering PayPal as one of several payment options customers expect at checkout consistently reduces cart abandonment for first-time buyers.
Fees: 2.6% + 30¢ per domestic transaction for standard card payments. PayPal-to-PayPal payments are lower.
Key features:
Best for: Adding as a secondary payment option alongside a primary gateway. Very few Australian ecommerce stores should remove PayPal entirely — even if it's not your primary processor.
Worth noting: PayPal's transaction fees are on the higher end. Most stores use it as a complementary option rather than their sole gateway.
2Checkout — now operating as part of Verifone — is one of the strongest options for Australian online businesses with significant international sales. Its multi-currency support and global reach make it a strong payment solution for sellers expanding beyond Australia.
Fees: From 3.5% + 35¢ per transaction. Higher than most alternatives, which is the primary drawback, and processing fees plus currency conversion costs can materially affect margins on international sales.
Key features:
Best for: Australian businesses with a significant international customer base whose business model depends on cross-border growth, where support for multiple currencies and global payment method coverage justifies the higher fee structure.
Worth noting: At 3.5% per transaction, 2Checkout is one of the more expensive options. For purely domestic stores, the fee premium is difficult to justify against alternatives like Stripe or eWay.
SecurePay is an Australian-owned payment gateway trusted by over 90,000 local businesses. Its competitive pricing and strong fraud detection make it a practical option for a small business owner focused on the domestic market.
Fees: From 1.75% per transaction — among the most competitive rates available for domestic Australian transactions.
Key features:
Best for: Small to medium Australian ecommerce businesses focused primarily on domestic sales where competitive transaction fees are a priority.
Worth noting: SecurePay lacks some features that larger stores require — support across popular payment methods, POS support, and international transaction capability are more limited than alternatives. Worth checking whether your requirements fall within its feature set before committing.
|Best For|Transaction Fee|International| |---|---|---|---| |Stripe|Most stores — flexible & developer-friendly|1.7% + 30¢|Excellent| |eWay|High-volume domestic stores|Quote-based|Good| |Square|Omnichannel (online + physical)|1.9%|Limited| |PayPal|Secondary option / trust signal|2.6% + 30¢|Good| |2Checkout|International-focused stores|3.5% + 35¢|Excellent| |SecurePay|Small domestic stores, cost-sensitive|1.75%|Limited|
The best choice depends on how you need to accept payments and charge customers across online, in-person, and recurring channels. For most Australian ecommerce stores starting out in 2026, Stripe is the default recommendation — clean integration, competitive fees, strong fraud protection, and excellent documentation. eWay is worth considering for established stores with high domestic transaction volumes. Add PayPal as a secondary option regardless of which primary gateway you choose.
If you're selling internationally, 2Checkout or Stripe with multi-currency enabled are the strongest options. Different business needs may call for different payment gateway providers and payment solutions, especially for Australian businesses balancing domestic and cross-border sales. If you're running both a physical store and an online presence, Square simplifies your operations significantly.
BNPL services — Afterpay, Zip, Klarna, and PayPal Pay Later — have become a standard payment expectation among Australian consumers, particularly for purchases in the $50–$500 range. As one of the extra services some gateways offer beyond core processing, BNPL is now supported either natively or through plugins by most major providers.
If your average order value falls in this range, offering at least one BNPL option at checkout is worth the setup effort — conversion rate improvements are well-documented for stores that add it. Afterpay in particular has strong brand recognition among Australian shoppers and is now available natively through both Stripe and Shopify Payments, with these add-ons able to support conversion while complementing recurring payments where relevant.
What is the cheapest payment gateway in Australia?SecurePay offers some of the lowest domestic transaction fees at 1.75% per transaction. Stripe at 1.7% + 30¢ is competitive at lower transaction volumes and becomes comparable or cheaper at higher volumes depending on average order size. Just compare monthly fees and processing fees, not only the headline transaction rate.
Do I need a merchant account for a payment gateway?Most modern payment gateways — including Stripe, Square, and PayPal — include a merchant account as part of the service, so you don't need to set one up separately. Some older gateways like eWay may require a separate merchant account through your bank. Pin Payments is another option for some Australian stores, especially if you want a more local-focused alternative.
Can I use multiple payment gateways on my store?Yes — and for most stores, you should, especially if your checkout mix includes card payments, PayPal, or direct debit where relevant. A primary gateway for card payments combined with PayPal as a secondary option covers the majority of Australian consumer preferences. Adding Afterpay or Zip covers the BNPL segment. Most ecommerce platforms support multiple payment methods at checkout without significant additional complexity.
Which payment gateway is best for Shopify in Australia?Shopify Payments (powered by Stripe) is the simplest option for Shopify stores — it's built in, avoids additional transaction fees, and supports Apple Pay, Google Pay, and Afterpay natively. If Shopify Payments doesn't suit your requirements, Stripe and PayPal both integrate cleanly with Shopify, so compare the integration process and available software integrations when choosing between native and third-party options.
Which payment gateway is best for WooCommerce in Australia?Stripe and PayPal both have well-maintained official WooCommerce plugins and are the most commonly used gateways for Australian WooCommerce stores. eWay and SecurePay also have WooCommerce integrations and are worth considering for stores prioritising domestic-focused options.
Choosing the right gateway is step one — setting up payments online correctly in your ecommerce platform is step two. A poorly configured gateway creates checkout friction, misses fraud flags, and can leave your store non-compliant with PCI DSS standards.
I integrate payment gateways into Shopify, WooCommerce, and Magento stores as part of ecommerce development projects and as standalone integrations for existing stores, with implementation shaped by each store’s needs, including extra services and software integrations. The right integration process helps online businesses accept payments reliably with minimal technical effort. If you're setting up a new store or switching gateways, get in touch and I'll give you a straight recommendation based on your specific situation.
