Our Customer Solutions team are here to find a solution for you and will ensure that you're regularly updated about the progress we are making to resolve your complaint.

We'll always contact you to share our final response, provide an explanation of what we have found and why we made the decision.

If you're still unhappy.

If you're still not satisfied with our response after we have fully investigated your complaint, you can seek assistance from the Banking Ombudsman Scheme, which provides an independent dispute resolution service. The Banking Ombudsman can help customers resolve concerns and disputes with their bank, free of charge.

The Banking Ombudsman is always available to provide advice on whether the complaint resolution proposed by Westpac is fair and reasonable. We encourage you to discuss your queries with the Banking Ombudsman Scheme – providing the Banking Ombudsman Scheme with an overview of your concern and Westpac’s suggested complaint resolution. However, please note that before the Banking Ombudsman can formally investigate your complaint, it must first have been fully reviewed by Westpac’s Customer Solutions team.
