High-Risk Merchant Accounts in Australia: Gateways, Approval and Costs

Most high-risk owners hear "no" in one of two ways: a declined application, or an account that works for a while and then gets closed, sometimes with funds held.

• Payment apps publish restricted-business lists in their terms. Sign-up is quick because the full review often comes later. When the app works out what you sell, it can close the account or hold your money.
• Banks set their own risk policies for merchant facilities. A category outside that policy is usually declined, however clean your record is.

Neither is personal. Each provider is deciding how much chargeback and fraud risk it wants to carry. The fix is a provider whose acquiring bank accepts your category up front, so you don't lose processing later when someone finds out what you sell.

The card networks and banks look at the same things in Australia as anywhere else:

• What you sell. Every merchant gets a merchant category code (MCC), a four-digit code for its type of business. Visa and Mastercard treat some codes as higher-risk, and Mastercard makes merchants in certain categories register before they can take cards.
• How you sell. Online and phone sales (card-not-present) carry more fraud. Subscriptions, free trials and pre-orders draw more disputes.
• When you deliver. Travel, event tickets and anything paid for months ahead leave the bank exposed if you can't deliver.
• Your history. High chargebacks, a past account closure or no processing history at all.

For the category codes, the difference between high-risk and prohibited, and how to look less risky to an underwriter, see what makes a business high risk.

High-risk isn't the same as illegal. Two Australian rules stop some businesses taking certain payments no matter who processes for them.

Online wagering. As published by the Australian Communications and Media Authority (ACMA) and the Department of Infrastructure, online wagering service providers are banned from accepting credit cards, credit-related products (for example, digital wallets) or digital currencies such as cryptocurrency. The ban commenced on 11 June 2024 and covers online and telephone betting, with penalties of up to $247,500. Lotteries are not covered.

Vapes. As published by the Therapeutic Goods Administration (media release, 28 June 2024), from 1 July 2024 "only established pharmaceutical supply chains are permitted to distribute and supply vapes," and non-pharmacy retailers, "such as tobacconists, vape shops and convenience stores," are prohibited from supplying any type of vape.

A merchant account doesn't change either rule. If a provider offers to process something the law bars, that's a reason to walk away, not a solution.

The acquirer (or acquiring bank) is the bank that holds your merchant account, processes your card sales and carries the risk if customers dispute them. It's the acquirer, not the app or the gateway, that decides whether you're approved. START places high-risk Australian merchants in one of two ways:

Which route fits depends on your product, where your customers are and the currency you charge. Acquirers differ in the categories they accept, so the route is decided case by case. One thing to know up front: a card's issuing country (where the customer's bank is) sets whether a sale is domestic or cross-border. Australian cards on a U.S. account are cross-border sales, and so are U.S. cards on an Australian account. International card payments for Australian businesses explains what that costs.

Tell us what you sell and where your customers are, and we'll tell you which account fits. For the documents Australian applications need, see how to get a merchant facility in Australia. Our guide to Australian merchant accounts compares the three setups side by side.

A payment gateway is the software that sends card details from your website or checkout to the acquirer. It's the plumbing, not the approval. A gateway can't get you approved if no acquirer will take your business, and once you're approved, most standard gateways will work.

So when you see an offer for a "high risk payment gateway in Australia," read the fine print. Many are a merchant account from an overseas acquiring bank, bundled with a gateway and sold as one product. That can be a legitimate setup. Before you sign, ask:

• Who is the acquiring bank, and in which country?
• What currency do I settle in, and where does the money land?
• What reserve is held, for how long, and when is it released?
• Does the acquirer know exactly what I sell? (If not, you're back to the app problem.)

On the U.S. side, START specializes in Authorize.Net. Authorize.Net says it needs a merchant account from a provider in the U.S. or Canada, so it goes with a U.S. account, not an AUD one. Your AUD gateway is matched to your Australian setup. For fraud filters, recurring billing and checkout options, see how high-risk payment gateways work.

Across the industry, high-risk accounts usually cost more than standard ones. What you pay depends on your category, volume, history and the acquirer. Expect some of these:

• Higher processing rates than a low-risk shop pays, because the acquirer carries more chargeback and fraud risk.
• A rolling reserve. The acquirer holds back a share of each day's sales for a set period, then releases it on a rolling basis. It covers refunds and chargebacks if something goes wrong.
• Chargeback fees on each dispute, and sometimes higher setup or monthly fees.

An illustrative example (round numbers for the math, not a quote): with a 10% reserve held for six months, a business taking $50,000 a month would have $5,000 a month held back. After six months, about $30,000 is sitting in reserve, and each month's release roughly matches the new amount held. Plan your cash flow for it.

Two Australian changes matter here. From 1 October 2026, lower interchange caps (interchange is the fee that goes to the customer's card-issuing bank) apply to Australian cards; how much of that reaches you depends on your pricing plan, covered in merchant fees in Australia. And from the same date, you can't add a surcharge to eftpos, Mastercard or Visa payments, so higher costs have to be built into your prices. See Australia's card surcharge ban.

For how reserves are negotiated and what to check in a reserve clause, see high-risk rates, fees and reserves.

A chargeback is when a customer disputes a charge with their bank and the money is taken back from you. Visa's and Mastercard's monitoring programs apply in the Asia-Pacific region, so they apply to Australian merchants too. As of September 2026:

Your acquirer will usually step in well before either limit, and a high-risk acquirer watches closely. Clear billing descriptors, fast refunds and easy cancellation prevent most disputes. For the full formula and tools that stop disputes before they count, see chargeback ratio limits and management.

1. Don't open a new app account under another name. It usually ends the same way, and it can look like you're hiding something.
2. Download your records now: sales history, refunds, disputes and any messages about the closure. An underwriter will ask for them.
3. Find out what's held and why. Check the provider's terms for how long it can keep funds; each app's terms say something different.
4. Apply with the full story. Tell your new provider what you sell and why the last account closed. Disclosing it up front is what keeps the next account open.

For releasing held funds and checking whether you've been added to the MATCH list (a card-network file of closed merchants), see what to do after a payment app shuts you down.
