Holding Foreign Currency in Australia vs Converting to AUD

What a foreign-currency account is

Commonwealth Bank's own page describes its Foreign Currency Account as "a flexible way to make, receive and convert regular payments in foreign currencies," listing features including making and receiving payments in most convertible currencies through NetBank or the CommBank app, no requirement to convert between AUD and the foreign currency every time you make or receive a payment, and the flexibility to hold the currency and convert it whenever you choose (fetched from commbank.com.au, effective date 8 September 2026). At that same date, CBA listed $0 monthly account fees and the potential to earn interest on selected currencies, with rates varying by currency and account balance tier.

NAB offers a comparable product aimed at its business customers — its own page describes a Foreign Currency Account letting a business "make or receive payments in foreign currencies... without having to convert to or from Australian Dollars first," with 16 currencies to choose from (fetched from nab.com.au, as at September 2026). NAB's version is positioned for businesses and frequent international transactors rather than as a general personal-banking product, so it's worth checking directly with NAB (or another bank) whether an equivalent retail option exists for your situation before assuming this product applies to you personally.

What holding foreign currency actually changes

Opening a foreign-currency account changes when the currency conversion happens, not whether it eventually happens if you plan to spend the money in Australia. The money sits in the account in its original currency until you choose to convert some or all of it to AUD, at which point ordinary exchange-rate movement between now and then applies, in either direction. CBA's account page notes this directly: if you later convert to Australian dollars, "the Australian dollar amount may be less than it was at the time of deposit, due to exchange rate movements over time" — it can equally be more, for the same reason.

This is genuinely different from converting the whole amount on arrival, which locks in a single rate for the entire sum at that point in time. Neither approach is inherently safer — each simply moves the currency-movement exposure to a different point in time, and how that trade-off sits with you depends on your own circumstances and risk tolerance, not on anything this article can tell you.

Why someone might choose to hold rather than convert immediately

A few genuine, factual reasons this option gets used: if you're not planning to spend the full amount in Australia straight away (for example, some of it is earmarked for an overseas expense later), holding it in the original currency avoids converting it twice; if you're still deciding how much of the sum you'll ultimately need in AUD versus keeping some in the original currency for other purposes; or if you simply want to avoid converting the whole amount at a single moment in time and would rather convert in stages as you need AUD.

None of these are a claim that holding produces a better outcome than converting immediately — they're descriptions of situations where someone might prefer the flexibility. Migratio doesn't hold a financial services licence and doesn't advise on whether to hold or convert, or on timing either decision.

The alternative: a forward contract, if timing matters

If your real concern is uncertainty about a future exchange rate — for example, you know you'll need to convert a large sum to AUD on a specific future date, such as a property settlement — a forward contract is a different mechanism some specialist foreign-exchange providers offer, which fixes an exchange rate now for a conversion that happens on an agreed future date. This is a distinct product from simply holding foreign currency in a bank account, and it comes with its own terms (typically a deposit, and a binding commitment to the agreed rate whichever way the market subsequently moves) — see our separate explainer on forward contracts, limit orders and spot transfers for how that mechanism works in more detail.

What to check before opening one

If you're considering a foreign-currency account, confirm directly with the bank: which currencies it supports (CBA and NAB's lists differ, and neither covers every currency), whether it charges account fees or transaction fees on top of any conversion margin, whether it pays interest and on what terms, and whether it comes with a debit card or is transaction-account-only. These details change over time and differ bank to bank, so check the bank's own current page rather than relying on a summary from elsewhere, including this one.

Does a foreign-currency account avoid exchange-rate risk?

No — it delays when the conversion happens rather than avoiding the exchange-rate movement altogether. If you convert later, the rate at that point could be better or worse than the rate on the day the money arrived.

Which Australian banks offer a foreign-currency account?

Commonwealth Bank offers one aimed at personal customers; NAB's version is positioned for business customers. Availability, currencies supported and fees vary, so check directly with each bank rather than assuming they're equivalent products.

Is holding foreign currency better than converting straight away?

This is a decision about your own plans and risk tolerance, not something this article — or Migratio generally — can tell you. Migratio doesn't hold a financial services licence and doesn't provide financial advice.

Can I get a debit card linked to a foreign-currency account?

This varies by bank and by account — check directly with the bank whether the specific foreign-currency account you're looking at comes with card access or is transaction-only.

What if I need the AUD amount fixed for a specific future date instead?

That's a different tool — a forward contract, offered by some specialist foreign-exchange providers, fixes today's exchange rate for a conversion happening on an agreed future date, rather than holding the currency indefinitely.
