International wire transfer from Australia: how SWIFT actually works

What SWIFT actually is

SWIFT (the Society for Worldwide Interbank Financial Telecommunication) is a messaging network that banks use to instruct each other securely — it carries the payment instruction, not the money itself. The message format that carries a standard customer payment instruction between banks is commonly referred to by its category code, MT103; this is background terminology rather than something you'll need to interact with directly as a sender. The actual funds move separately, bank to bank, following the instruction the SWIFT message carries.

This distinction — a messaging network versus the actual movement of funds — is why a wire can appear to "pass through" banks that never touch your account directly. Each bank in the chain confirms the instruction, moves its own leg of the payment on to the next bank, and only the final bank in the chain actually credits the recipient. SWIFT itself doesn't hold or move money at any point; it standardises how the instruction is communicated so that banks with no direct relationship to each other can still complete a payment via one or more intermediaries.

Why the payment 'hops' through banks you've never heard of

For a currency other than AUD, your Australian bank typically doesn't have a direct relationship with every bank in the world — instead it uses a correspondent bank in the destination country or currency zone to complete the payment. National Australia Bank's own page on receiving money from overseas names its correspondent banks by currency: USD payments route via Citibank NA in New York, GBP via Royal Bank of Scotland in London, JPY via Sumitomo Mitsui Banking Corp in Tokyo, EUR via Deutsche Bank in Frankfurt, and NZD via Bank of New Zealand (nab.com.au, as published September 2026). This is why a payment to, say, a UK account can show a US or European bank's name somewhere in the transaction trail — it's a real intermediary, not an error.

Each bank in that chain can, and sometimes does, deduct its own handling fee before passing the payment on, which is a separate mechanic from the fee your own bank charges you upfront. The specific fee-allocation options that determine who absorbs those deductions are covered in the dedicated page linked below.

What you need to send one

The core requirement is the recipient's account identifier in the format their bank uses — many countries use an IBAN, while Australia (on the receiving end) uses a BSB and account number instead, per NAB's own page: "The BSB and bank account number you want the money sent to. (Australian banks don't use IBANs.)" You'll also generally need the recipient bank's SWIFT/BIC code — NAB's own is NATAAU3303M, and ANZ's is ANZBAU3M (or ANZBAU3MXXX), both published on the banks' own sites as of September 2026. Getting the recipient's name exactly as it appears on the account, and the correct account identifier, matters more for a wire than for many domestic transfer methods — NAB's own page notes it does not check names against account or BSB numbers for domestic transfers, which is a useful caution to carry into any transfer: verify the details are correct before sending, rather than assuming a mismatch will be caught automatically.

"Wire transfer" versus what Australian banks actually call it

In the US, "wire transfer" is the standard consumer term for this product. In Australia, the equivalent retail product is generally branded differently by bank — Commonwealth Bank calls its version an "International Money Transfer (IMT)" and the phrase "telegraphic transfer" barely appears on CBA's own retail pages at all. A couple of other banks do use "telegraphic transfer" as their actual product name for the international service — which one depends entirely on the bank, and using the wrong bank's terminology can point you at the wrong page or even the wrong (domestic) product. The full, bank-by-bank breakdown of what "telegraphic transfer" specifically means at each institution is linked below — it's genuinely inconsistent enough to be worth checking before you search.

When a wire is genuinely the only option

Most everyday remittances — supporting family, paying a smaller bill overseas — can go through a specialist FX provider or a remittance app that doesn't use a traditional SWIFT wire for every leg. A bank wire tends to be the practical option specifically for: a corridor or currency a specialist provider doesn't support; a large, one-off payment like a property settlement where the receiving party (a solicitor's trust account, for example) specifically requires a bank-to-bank wire rather than a third-party app; or a business payment where the counterparty's own banking requires it.

Some payment recipients — a government agency, a court, a conveyancer, an overseas university's finance office — will specify in their own instructions that they only accept a SWIFT wire to a named account, rather than a payment through a third-party app. When that's the case, the choice isn't really yours to make on cost grounds at all; the recipient's own requirement decides the method, and the comparison that still matters is which bank or provider offers the wire itself at the lowest total cost. None of this means a wire is always the more expensive or slower choice more generally — that depends on the specific corridor and amount, and is worth checking with the delivered-amount comparison method covered in the dedicated cost page linked below.

Tracking a wire that's taking longer than expected

Once a wire has left your bank, only the sender can generally track it — the recipient's bank cannot look up an inbound payment it hasn't received yet, per ANZ's own guidance for a comparable inbound scenario. If a wire seems delayed, the practical next step is to check with your own bank rather than the recipient's, since your bank holds the transaction reference and can trace the payment through the correspondent chain. A dedicated page on tracking a transfer, including SWIFT's own tracking mechanisms, is linked below.

Is a wire transfer the same as SWIFT?

Not exactly — SWIFT is the messaging network banks use to instruct each other, and a wire transfer is the product that uses it. The funds themselves move bank to bank, following the instruction the SWIFT message carries, rather than moving through SWIFT itself.

Why do Australian banks not call this a wire transfer?

"Wire transfer" is common US retail banking terminology. Australian banks generally use their own product names for the same underlying service — Commonwealth Bank, for example, calls its version an International Money Transfer (IMT) rather than a wire.

Why did the recipient get less than I sent on a wire?

A correspondent bank in the payment chain can deduct its own handling fee before passing the payment on, separately from any fee your own bank charged you upfront. Which party absorbs that deduction depends on the fee option chosen when the payment was set up.

What's the difference between a wire transfer and a telegraphic transfer?

They generally describe the same underlying product — a bank-to-bank transfer routed via SWIFT and correspondent banks — but which name a specific Australian bank uses varies, and at one major bank "telegraphic transfer" actually means a different, domestic-only product. Check the specific bank's own terminology before assuming.

Do I need an IBAN to send money from Australia?

You need the recipient's account identifier in whatever format their own bank and country use — many countries use an IBAN, and Australia's own banks are identified by a BSB and account number instead, not an IBAN.
