Is it legal for a business to refuse cash payments in Australia?

You've probably walked into a café or a tradie's office and seen a sign that reads "card payments only." It's more common than ever. But whether a business can legally refuse payment by cash in Australia is a question that trips up a lot of small business owners, and gets misunderstood by plenty of customers too. The short answer: yes, in most circumstances, a business can refuse cash. But the full picture has some important caveats.

What Australian law actually says about cash

Australia's currency is backed by the Currency Act 1965, which establishes Australian banknotes and coins as legal tender. "Legal tender" is the phrase that causes most of the confusion. People assume it means any business must accept cash. It doesn't.

Legal tender status means that cash is a valid form of payment that can be used to settle a debt. It does not mean a business is forced to accept it. The Reserve Bank of Australia is explicit on this: businesses can set their own payment terms before a transaction takes place. If a café puts up a sign saying it's card-only before you order, it has set those terms. You choose to transact on that basis, or you don't transact at all.

The key legal concept here is "prior agreement." Once a business clearly communicates its payment policy before a sale is completed, a customer who proceeds accepts those terms. There's no law in Australia that compels a business to accept cash as long as it discloses its payment method requirement upfront.

When refusing cash could actually be a problem

There are situations where refusing cash gets legally messy. The clearest one involves pre-existing debts. If someone owes you money under a contract that didn't specify payment method, and they try to settle that debt with legal-tender cash, refusing it could put you on shaky legal ground. The debtor has offered a valid form of settlement. Courts have found in the past that refusing a valid tender of payment can affect a creditor's ability to claim costs or interest in recovery proceedings.

There's also a fairness concern that regulators are starting to pay attention to. Older Australians, people in regional areas, and those without bank accounts rely on cash far more than the average city-based customer. The Australian Government has flagged this issue in its broader payments reform work, and it's worth knowing that the policy environment could shift. The Treasury's payments system review identified cash accessibility as a concern, particularly for vulnerable groups.

For now, there's no federal law requiring businesses to accept cash. But if your business operates in a space that serves people who genuinely depend on cash access, refusing it could attract scrutiny or reputational damage even if it's technically lawful.

Practical rules for businesses going cashless

If you're running a small business and want to stop accepting cash, a few practical steps keep you on solid legal and commercial footing.

  • Display your policy clearly before the point of sale. A sign at the entrance or on your website is enough. The policy needs to be visible before any transaction begins, not revealed at the register after someone has already committed to a purchase.
  • Don't apply it retroactively to existing debts. If a customer owes you money under a prior arrangement, work out the payment method before you refuse a cash settlement.
  • Review your contracts. If your standard agreements or invoices specify payment methods, make sure they match your actual policy. Inconsistency creates risk.

Surcharges are a related issue worth noting. Businesses in Australia can charge a surcharge for card payments, but the Australian Competition and Consumer Commission (ACCC) rules state that surcharges must not exceed the actual cost of processing the payment. Excessive surcharges are prohibited under the ACCC's payment surcharge rules. This matters if you're accepting cards but pricing in a way that effectively penalises card users beyond your actual costs.

Does this apply to all types of businesses?

The same rules apply whether you're a sole trader, a company, or a partnership. The legal tender framework and the "prior agreement" principle don't change based on business structure. What changes is the context in which the transaction happens.

Online businesses, for instance, rarely offer cash as a payment option at all. That's entirely lawful because the transaction terms are set before checkout. In-person businesses have a little more obligation to make their policy visible, simply because customers can walk in without any prior notice of the terms.

Government agencies sit in a different category. Some government bodies are required by law to accept cash for certain transactions, particularly those involving fees, fines, or statutory obligations. Private businesses aren't subject to the same rules.

What this means if you're hiring or growing your business

Payment policy is one of those operational decisions that often gets overlooked when a small business is scaling up. If you're at the stage of hiring your first employee, it's worth locking in your payment procedures as part of your broader business systems, including how you issue invoices, what payment methods you accept, and how you communicate those terms to customers.

Similarly, if you're thinking about small business accounting practices, your payment method policy has a direct effect on your recordkeeping and cash flow management. Card-only businesses often find reconciliation simpler, but they also take on processing fees that need to be tracked and accounted for correctly.

The bottom line

In Australia, a business can legally refuse payment by cash, provided it makes that policy clear before a transaction is agreed to. Legal tender status gives cash legitimacy as a form of payment, but it doesn't obligate any private business to accept it. The main exceptions involve pre-existing debts and certain government transactions. For small business owners, the practical step is simple: communicate your payment policy upfront, keep your contracts consistent, and stay across any surcharge rules that apply to your card payment setup.

Policy in this space is not static. The federal government has been actively reviewing Australia's payments framework, and it's possible future legislation could impose obligations on certain types of businesses to maintain cash acceptance. For now, going cashless is lawful. Watch this space.
