About this app

Westpac One is online banking that’s easier, faster and smarter than ever before.

With this app you can do so much more of your banking, no matter where you are. Do the usual stuff like transfer money and pay people, but also do the fancy stuff like:

- apply for loans and credit cards
- block your credit or debit card if you lose it
- pay someone in Australia
- open an account
- open and view term deposits
- and much more.

There’s also a smart Timeline feature – where you can view, search and filter all your transactions from all your accounts in the one place.

Plus get loads of other cool features as well, like:

- log in with a PIN for faster access to Westpac One
- check the balance of selected accounts and transfer between those accounts without having to log in
- monitor your monthly spending patterns with our Spending Meter.

All backed up by Westpac’s world-class online security, Online Guardian.

This app stops working frequently and requires uninstalling and then reinstalling to reset it. very tricky when out and about and needing to check balances, etc. When it is working correctly, it is fabulous!
