Set yourself up for the bonus interest by setting up an automatic payment for the middle of each month to ensure that your monthly deposit is made in plenty of time.

Interest is subject to change and is calculated daily on the full credit balance and paid (less tax) into your Westpac Bonus Saver account on the last day of each month, unless you request it is paid into another account. Potential rate equals the sum of the base and bonus rate. The above rates are not available to financial institutions.


The term 'free' refers to Westpac fees only. Service fees still apply for example, clearance fees. Fees are subject to change and relate to Westpac Bonus Saver only. Standard fees will apply to the account which money is being transferred to or from.
