Commonwealth Bank vs Airwallex for Business: Fees, FX and What Protects Your Money

Commonwealth Bank or Airwallex? For an Australian business that works mainly in Australian dollars, CommBank's Business Transaction Account is the natural home: there is a $0 monthly fee option, deposits at an Australian bank are covered by the government's Financial Claims Scheme up to A$250,000 per account holder, and CommBank waives its own transfer fee on international payments made online. Airwallex is the better tool when foreign currency is a regular part of your month: it publishes its conversion cost — 0.5% above interbank for major currencies, 1% for others — holds balances in many currencies and pays out locally in other countries, but it is not a bank, so balances are safeguarded rather than covered by the Financial Claims Scheme. The figures below were read from both companies' own pages and from APRA on 7 November 2026.

The question people actually ask is usually "which is cheaper for international payments?". The honest answer is that CommBank does not publish the number you need to answer it: its transfer fee is waived online, but the margin inside its exchange rate is not stated. That is why this comparison spends as long on how to measure cost as on the published fees.

The two side by side

What protects your balance

The Financial Claims Scheme is the Australian government's deposit guarantee. APRA states that deposits are protected "up to a limit of $250,000 for each account holder at each bank, building society and credit union". A business account at CommBank is a deposit at a bank, so it sits inside that scheme.

Airwallex is not a bank. Its help centre says the Australian entity "segregates customer funds from Airwallex's own operational funds", held with Australian authorised deposit-taking institutions, per its safety article. Segregation keeps your money apart from the company's own, which matters if the company fails; it is not the same as the government scheme that stands behind a bank deposit.

The practical conclusion is the same one that applies to any payments platform: keep the cash your business could not do without at the bank, and use the platform for money that is moving. Our Airwallex review covers its licences in each country and the regulatory record, including AUSTRAC's 2026 order for an external audit.

International payments: the published fees, and the one that is not published

CommBank's international money transfer page states: "We waive the transfer fee when you make international payments using NetBank, the CommBank app or CommBiz." The waiver excludes AUD-to-AUD transfers. For CommBiz users, CommBank adds that it will "pay any correspondent bank fees when you send a cross-currency international money transfer (Japanese Yen excluded)", though the recipient's own bank may still charge.

What the page does not give is the exchange-rate margin. It promises "competitive foreign exchange rates" without a number. Every bank conversion has a margin built into the rate; a $0 transfer fee tells you nothing about how large it is.

Airwallex publishes its margin as a percentage above interbank — 0.5% for major currencies and 1% for the rest — and charges a flat A$10-30 when a payment has to go over SWIFT. Local transfers are listed as free.

So you cannot settle "which is cheaper" from the fee pages. You settle it by quoting the same payment at both.

How to compare the real cost in ten minutes

• Pick one payment you make every month, in its real currency — for example US$10,000 to a supplier.

• At the same moment, note the mid-market rate from any market-data source.

• Get CommBank's quote for the AUD it will debit to deliver US$10,000, and Airwallex's quote for the same.

• For each, compare the AUD debited against US$10,000 converted at the mid-market rate. The difference, as a percentage, is the real cost of that payment — fee and margin together.

As a reference point from Airwallex's own numbers: at 0.5% above interbank, a payment needing about A$15,000 of conversion costs about A$75 in markup, with no transfer fee if it goes out locally, and A$10-30 more if it needs SWIFT. If CommBank's quote on the same payment is within that range, the bank wins on simplicity; if it is well above it, the gap repeats every month.

Where each one is clearly better

CommBank is better for:

• A business that banks mainly in Australian dollars and wants one account for everything domestic.

• Cash and cheques: branches, assisted transactions and QuickCash deposits exist, at the prices in the table.

• Lending and the wider relationship — overdrafts, loans and merchant services sit with the bank, not with a payments platform.

• Balances you need protected by the Financial Claims Scheme.

Airwallex is better for:

• Businesses paid in foreign currencies, who can keep the currency and pay suppliers in it without converting twice.

• Paying contractors or suppliers in many countries over local rails.

• Team cards that spend in several currencies; Airwallex advertises zero international fees on Explore cards.

• Anyone who wants the conversion cost stated as a percentage rather than buried in a rate.

Use both when you sell or buy abroad but keep your reserves at home. The common pattern is CommBank for payroll, tax, BAS payments and reserves; Airwallex for foreign-currency receipts and supplier payments; and a monthly sweep of surplus AUD back to the bank.

Frequently asked questions

Is Airwallex better than Commonwealth Bank for international payments?

It depends on the margin CommBank applies to your payment, which it does not publish. Airwallex states its cost — 0.5% above interbank for major currencies — while CommBank waives its transfer fee online but builds its margin into the rate. Quote the same payment at both and compare the AUD debited.

Does CommBank charge for international transfers?

CommBank says it waives the transfer fee for international payments made through NetBank, the CommBank app or CommBiz, excluding AUD-to-AUD transfers. The exchange rate it applies still contains a margin, and the recipient's bank may charge its own fee.

Is money in Airwallex protected like a CommBank account?

No. A CommBank deposit is covered by the Financial Claims Scheme up to A$250,000 per account holder per bank. Airwallex is not a bank; it holds an Australian Financial Services Licence and segregates customer funds from its own, which is a different protection from the government scheme.

How much is the CommBank Business Transaction Account monthly fee?

CommBank offers a $0 monthly fee option, suited to banking mostly online, and a $10 option that includes 5 assisted transactions. Assisted transactions otherwise cost $5 each, and a QuickCash deposit $10.

Can I use CommBank and Airwallex together?

Yes, and many businesses do. CommBank holds the domestic operating account and reserves; Airwallex handles foreign-currency receipts and payments; money moves between them on a schedule.
