BankSA Savings Account Rates

Challenger

BankSA is a South Australian bank, part of the Westpac Group, offering two savings accounts. The Incentive Saver is the ongoing account, paying a competitive rate when you grow your balance by at least $50 each calendar month. Customers under 21 need only grow their balance by $0.01 to qualify. Miss the growth condition in any month and the rate drops to the base rate of 0.10% p.a. for that month — you can requalify the following month.

The Maxi Saver offers an introductory rate for the first six months, then reverts to a very low ongoing rate. It suits savers opening a new account who plan to move their money after the intro period ends rather than park a long-term balance.

Deposits with BankSA are protected under the Financial Claims Scheme up to $250,000 per account holder per ADI.

How to earn it

Grow your account balance by at least $50 each calendar month (customers under 21 need only grow by $0.01). The growth must occur before the last business day of the month, and your balance must stay above $0 throughout.

The $50 growth requirement is based on net deposits, not including interest — if you withdrew money during the month, you need to deposit enough to bring the closing balance above last month's level by at least $50. Missing by even one cent drops you to the base rate of 0.10% p.a. for that month.
