How to Recover a Mistaken Bank Transfer in Australia

Don't Panic — But Act Fast

Sending money to the wrong bank account is more common than most people realise. A single mistyped digit in a BSB or account number, an outdated invoice, or a scammer supplying false details can send your money somewhere it was never meant to go. The good news is that Australia has a formal process — the ePayments Code — that governs how banks handle these "mistaken internet payments." The bad news is that recovery is far from guaranteed, and your chances drop sharply with every day that passes. This guide walks you through exactly what to do.

Step 1: Contact Your Bank Immediately

The single most important action is to report the error to your bank as soon as you notice it. Time is the deciding factor in whether you get your money back, because once the unintended recipient spends the funds, recovery becomes extremely difficult.

Contact your bank by whatever channel reaches a human fastest — phone, in-branch, or secure messaging. If your bank has a dedicated fraud or disputes line, use it. Do not simply send an email and wait for a reply.

Have the following details ready:

• The date and time of the transfer
• The amount sent
• The BSB and account number you entered (the wrong ones)
• The correct BSB and account number you intended to use
• Your transaction reference number

Your bank will lodge a Mistaken Internet Payment (MIP) claim with the receiving bank on your behalf.

Step 2: Understand the ePayments Code

The ePayments Code, administered by the Australian Securities and Investments Commission (ASIC), sets out the process banks must follow when a customer reports a mistaken payment. In essence:

1. You report the error to your bank.
2. Your bank contacts the receiving bank and requests the return of funds.
3. If the receiving bank is satisfied a mistake occurred and the funds are still available, it places a hold on the money in the recipient's account.
4. The recipient is notified and given a chance to show they are entitled to the funds.
5. If they cannot, the money is returned to you.

The whole process depends on the funds still being in the recipient's account. This is why speed matters so much.

Step 3: Know the Timeframes

How quickly you report the error determines the process the receiving bank must follow:

As the table makes clear, reporting within the first 10 business days gives you the strongest protection. After seven months, recovery depends entirely on the goodwill of the person who received your money.

Step 4: Keep Detailed Records

Throughout the process, document everything:

• Note the date and time of every call or message to your bank
• Record the names of staff you speak with
• Keep all reference and case numbers the bank gives you
• Save copies of the original transaction receipt and any correspondence

If the matter later escalates to a complaint, this paper trail will be essential.

What If the Money Has Already Been Spent?

This is the hardest scenario. If the unintended recipient has already withdrawn or spent the funds before the receiving bank can place a hold, the ePayments Code cannot force them to repay money they no longer have. In this situation:

• The receiving bank will contact the recipient and request a voluntary return.
• If the recipient refuses, your bank will advise you that recovery through the banking process has failed.
• Your remaining options are civil remedies — you may be able to pursue the recipient through a state or territory small claims tribunal, or seek legal advice for larger amounts.

It is worth knowing that a person who knowingly keeps money they are not entitled to may be committing an offence, but enforcing that is a matter for police, not your bank.

If Your Bank Doesn't Resolve It

If you believe your bank or the receiving bank failed to follow the ePayments Code correctly, you can escalate to the Australian Financial Complaints Authority (AFCA). AFCA is a free, independent dispute-resolution service. Lodge a complaint with your own bank first and give it a chance to respond; if you are unsatisfied with the outcome, AFCA can review whether the correct process was followed.

Was It a Scam Rather Than a Slip?

There is an important distinction between an honest mistake and being deceived into sending money to a scammer. If you were tricked — for example, by a fake invoice, a compromised email, or a "your details have changed" message — the situation is treated as a scam rather than a simple mistaken payment. Report it to your bank immediately, and also to Scamwatch and ReportCyber. Recovery is often harder in scam cases because you authorised the payment, but banks are increasingly expected to help. See our guide on bank transfer scams in Australia for how to recognise and avoid them.

How to Prevent It Next Time

Recovery is stressful and uncertain, so prevention is always the better strategy:

• Verify the BSB before you send. Enter it into the BSBFinder Validator to confirm it belongs to the bank and branch you expect. If it does not match, stop and investigate.
• Double-check every digit of both the BSB and the account number against the details the recipient gave you.
• Copy and paste details from a trusted electronic source rather than typing them by hand.
• Send a small test payment — say, one dollar — to a new payee first, and confirm they received it before sending the full amount.
• Use PayID where available. Because PayID shows the recipient's registered name before you confirm, it gives you a chance to catch an error before the money leaves your account. See our guide on PayID vs BSB.

Summary

If you have sent a bank transfer to the wrong account in Australia, contact your bank immediately and lodge a Mistaken Internet Payment claim. The ePayments Code requires banks to try to recover the funds, but your chances are far better if you report within 10 business days and the money is still in the recipient's account. Keep thorough records, escalate to AFCA if the process is mishandled, and treat any deception as a scam requiring separate reporting. Best of all, verify every BSB with BSBFinder before you send — catching the error beforehand is always easier than chasing the money afterwards.
