Is your transaction a...


A disputed transaction is when you recognise the transaction, but may have an issue with the product/service received, e.g., goods or services not as described, defective or not received. 


A fraudulent transaction is when you have not actively participated in the transaction, e.g., your details were compromised without your knowledge, leading to unauthorised transactions on your accounts.


A scam transaction is when you participate in the activity, but were misled on the purpose, e.g., sharing a Security Code for Online Banking, purchasing an item online that never existed or investing in an opportunity that turned out to be fake.

What to do if you want to...

If you come across any transactions that you don’t recognise, a little investigation can be the simplest way to resolve or determine your next steps.

  • If you have an additional card holder, check if they’ve completed the transaction.
  • Look up additional merchant details including their contact details, website and location information by tapping the transaction in Online Banking or the Westpac App.
  • If you're familiar with the merchant, please contact them directly to resolve the matter.
  • If you're unfamiliar with the merchant, a quick Google search could help identify the merchant as many businesses trade under different name(s).
If you were unable to reach an outcome with the merchant or still don’t recognise the transaction, find out how to  dispute the charges in Online Banking or the Westpac App.
