Westpac Cookie Policy
This Cookie Policy is maintained by Westpac Banking Corporation ABN 33 007 457 141 AFSL and Australian credit licence 233714 (Westpac, us, we, our) and applies to the management and use of cookies and similar tracking technologies across Westpac's consumer digital channels, including Westpac.com.au, associated subdomains, authenticated and unauthenticated online banking services, and Westpac Consumer Banking mobile applications for Android and iOS.
This policy covers cookies, media pixels, tags, and other similar technologies used to support website and application functionality, security, performance measurement, personalisation, customer experience optimisation, consent management, and advertising activities where applicable.
Unless otherwise stated, this policy applies only to Westpac consumer banking digital channels and does not extend to other Westpac Group brands, products, websites, applications, or channels that are subject to separate privacy, cookie, or tracking technology notices.
References to “cookies” in this policy include cookies and similar tracking technologies, such as media pixels and tags, unless we state otherwise. These technologies may operate in different ways, but we use the term "cookies" collectively in this policy to make it easier to read.
What are cookies?
Cookies are small files that a website puts on your phone, tablet or computer when you visit. They can help remember information about your visit, such as your preferences or whether you're signed in. Similar technologies can operate in different ways, including by storing or accessing information on your device.
Why does Westpac use cookies?
We use cookies for a few different reasons:
- to make our website and mobile apps work. Some cookies are needed for basic things like signing in, keeping your information secure and making sure pages load correctly;
- to understand how people use our website and mobile apps. This helps us learn what is working well and what could be improved;
- to personalise your experience. For example, cookies can help us remember settings or show information that is more relevant to you; and
- to make our and third parties’ advertising more relevant. Some cookies help us and our partner third parties understand what products, services or content may interest you, so we can show you ads that are more useful and less random.
What information do cookies collect?
Cookies may collect information such as:
- the type of device and browser you use;
- your IP address (a number that helps devices connect to the internet);
- the pages you visit on our website;
- the links or buttons you click; and
- how long you spend on different pages.
Cookies do not usually identify you directly, but sometimes the information collected through cookies may be linked with information we already hold about you.
Setting your cookie preferences
If you are in the EU, EEA, UK or South America, you can choose whether to allow non-essential cookies through our cookie preference prompt or by selecting 'Manage cookie preferences'.
Your cookie selection is recorded against the device or browser used to access Westpac services. This means that you may be asked your cookie selection again when accessing Westpac services from a different device or browser, or where browser cookies, application data, local storage, or other device-level information has been removed, cleared, or reset.
Some cookies are essential because they help the website operate safely and correctly. These cookies cannot be switched off. Other cookies, such as analytics, marketing and third-party advertising cookies, can be turned on or off through our cookie settings.
If you choose not to allow non-essential cookies, our digital services will still work, although some features, content or advertising may be less tailored to you.
You can also manage or disable cookies through your browser or device settings. Some of our advertising and analytics partners also provide their own opt out tools for targeted advertising.
