How to report

Unrecognised Transaction

If you believe your security has been compromised or you notice a transaction you did not make, contact us immediately on 132 032.

There are many different types of credit card fraud, but at its simplest, it’s when someone obtains your card details and make transactions on your card without you knowing.

You may not be aware that your card has been used fraudulently until:

  • You receive your statement and find there are transactions that you didn’t make.
  • Our Fraud Detection Team advises you on unusual activity on your card and asks if the charges are yours.
    • We will send you an SMS (text) to confirm the transaction(s), and ask you to text back with your confirmation.
    • Westpac will never send links via email or SMS directly to our Online Banking sign-in page.

Lost or Stolen Cards

If your card is lost or stolen, please report it immediately so we can stop all transactions on your account. You will need your 8-digit customer number and password.

What to do if your wallet is lost or stolen
A lost/stolen wallet or handbag can result in the loss of your credit cards, as well as your driver's licence, mobile phone and car or house keys. Here are some tips to consider, should this happen:

  • Check the Lost Wallet Checklist (PDF 57KB) for a list of other Australia-wide financial institutions and their contact details for reporting lost cards
  • Report the loss or theft to police (call 000 or Police Help line 131 444)
  • Contact your insurance company, locksmith or mobile network provider (if keys or phone go missing too)
  • Access cash without your debit card at any Westpac ATM. Just call 132 032 and ask for Emergency Cash.

If your card is lost or stolen, please report it immediately so we can stop all transactions on your account. You'll need your 8-digit customer number and password.
