Responsible Disclosure at Westpac

Our approach

Westpac takes the protection of its customer information and confidential information very seriously.

We have rigorous security measures in place that protect the privacy and confidentiality of our customers, including industry best practice security and fraud detection techniques.

We also constantly monitor the environment for emerging cyber threats, security issues and potential vulnerabilities across the Westpac Group.

Our customers and others outside the organisation play an important role in providing us with information that supports our continuous efforts to keep our customers’ information safe and secure.

What to do if you receive a phishing or hoax email or SMS?

Customers may receive phishing or hoax emails, SMS or other correspondence from third-parties that may seek to impersonate our brand for the purposes of extracting information, or money from customers. If you have received a hoax or phishing email or SMS, forward it through to hoax@westpac.com.au, SMS it to 0497 132 032. Please visit the Fraud and Scams page to read more.

What to do if you have other information relating to potential security threats or issues?

We welcome any information you have on suspected cyber threats, or security issues. If you would like to report a suspected cyber threat, security issue or vulnerability, please send an email with the information to: vulnerability@westpac.com.au. When making your report, please include as much detail as possible to assist us.
