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

Last year, paying my tax through Westpac branch was quick and easy—just like swiping a card for coffee. This year, despite having all funds and staff help, the process was very slow, hopeless and felt like payment might be refused. I’m also concerned about printed receipts made from unsafe thermal paper, despite Westpac’s heavy tech usage, they still print unsafe receipts for customers, absolutly discusting!🤮

A genuinely sub-par banking app. I give it 1 out of 5 compared to ASB (5 stars). Westpacs App regularly hangs up on authentication then once that's happened it gets stuck. Your options are to force stop and restart or uninstall and reinstall even then its random. Tried 7 times to get in at farmers market today to do a bank transfer to a stall holder who eventually gave me the potatoes out of pity (so one bonus of the app).

possibly the worst app there could be in the finance sector. The interface doesn't show the details of the account and always throw the error. I have to login nunber of times just to get to the details.
