What you need to know
- On 5 May 2026, the RBA announced its decision to raise the cash rate by 0.25%.
- As a result, our variable rates are increasing by 0.25% per annum for most of our owner-occupied and investor home loans, effective 15 May 2026.
- You will receive an email to advise of our decision and will be notified of your new minimum repayment amount in a letter shortly after.
- If you are paying principal and interest, your new minimum repayment amount will apply from your next repayment due date on or after 20 June 2026.
- For interest-only customers, your next payment due on 1 June 2026 will consist partly of interest charged at the previous rate (up to 14 May 2026) and partly of interest charged at the new rate (15 May 2026 onwards).
- Interest rates on our Rate Breaker Loan are reviewed separately in line with the terms and conditions relevant to that product.
- Variable rates are also increasing for commercial loans. The increase of 0.25% per annum is effective from 27 May 2026 . Minimum repayment amounts for existing customers will not increase until 1 July 2026 , allowing time for all customers to be notified of their new repayment details by mail.

Important information
New repayment is for the repayment type, interest rate, loan balance, and years remaining on loan that has been input. It assumes the interest rate remains the same for the term of the loan. Changes in interest rates, loan balance and loan term will affect the new repayment amount.
The results from this calculator should be used as an indication only.
The outputs are based on a 364 day year; one year is assumed to contain exactly 52 weeks or 26 fortnights. All months and fortnights are assumed to be equal. Given some months are longer than others interest charged will vary depending upon the month.
The calculations do not take into account fees, upfront costs, charges or other amounts that may be charged to your loan (such as monthly or annual service fees). Continuing fees and charges will affect the repayment amount.
The calculator assumes that interest is charged to the loan account at the same frequency as the repayments are made. In practice, there may be differences between the timing of the loan repayments and the timing of the interest charges being added to the loan balance.
The amounts shown are rounded to the nearest dollar.
Frequently asked questions
Here are some ways to help lessen the impact of rising interest rates. Please contact us if you require any more information.
- Change your repayment frequency to weekly or fortnightly
This can reduce the amount of interest you need to pay over the life of your loan and may help with budgeting, particularly if you are paid by your employer weekly or fortnightly. - Utilise your offset accounts (if available on your loan)
Eligible customers can link up to six offset accounts to reduce the amount of interest due each month, meaning they are paying down the loan balance (the principal) faster.
If you are concerned about your ability to cope with this change, a range of options exists to help you. Please call our team of experts on 133 282.
The cash rate has an indirect impact on our costs. Put simply, when the cash rate goes up, it becomes more expensive for financial institutions like Great Southern Bank to lend money.
As a result of the cash rate increase, we have taken the difficult decision to raise our home loan variable interest rates in response. This has been done to ensure our continued ability to provide customers with the award-winning level of service they expect.
We review the Rate Breaker Package ‘reference rate’ against the Big 4 banks on the second Tuesday of each month. As a result, any changes to the Rate Breaker Package reference rate are announced separately and communicated to affected customers via email in the first instance, and then by letter shortly after.
The rate change detailed above applies to most variable owner-occupied and investor home loans. Rate Breaker Package Home Loans get reviewed in line with that product’s specific terms and conditions.
The variable rate applicable to your home loan depends on the type of loan, when you took it out, and any discounts or special offers available at the time. You can check your home loan contract to see what components make up your interest rate.
