Australian home lenders finished repricing variable mortgages in the first week of October after the Reserve Bank of Australia’s 30 September move to 4.60 percent, forcing borrowers to re-read comparison rates that now bake in two quarter-point hikes since midyear rather than a single isolated increase.
Commonwealth Bank, Westpac, ANZ and National Australia Bank each lifted standard variable owner-occupier rates by 25 basis points, effective dates clustered between 9 and 11 October depending on product and notice periods. Westpac advertised a 6.24 percent floor on its lowest variable product for new customers, while CBA’s comparable headline rate moved toward 6.49 percent once discounts expire. The spread between the cheapest and average booked rate is now wider than at any point since the 2022 tightening cycle began.
Comparison rates still confuse
Under National Consumer Credit Protection rules, lenders must display a comparison rate that includes interest plus most fees on a $150,000 loan over 25 years. The figure is a blunt instrument: it understates pain for large Sydney mortgages and overstates costs for small regional loans, yet it remains the only regulated shorthand for “true cost.”
When banks move variable rates in lockstep, comparison rates jump in tandem, often by more than the cash rate change because annual package fees and discharge costs are amortised across a smaller interest base in the formula. Brokers report a spike in “rapid refinance” enquiries from households whose fixed-rate cliff expired in September and who now face a second variable hike before Christmas.
Offset accounts change the maths
Customers with sizable offset balances feel the increase less because interest is charged on net debt. A household with a $600,000 loan and $80,000 in offset effectively pays interest on $520,000; a 25-basis-point rise adds roughly $1,300 a year before tax effects. Without offset, the same hike costs about $1,500 annually. Fixed-rate borrowers are insulated until expiry, but break costs have risen as swap rates shifted.
First-home buyers who entered the market in 2024 on low-deposit schemes face combined pressure from higher repayments and flat price growth in several capitals. CoreLogic data show auction clearance rates drifting lower in Melbourne and Sydney as bidders cap their finance pre-approvals.
Regulatory lens
The Australian Securities and Investments Commission has reminded lenders that promotional rates must match the comparison rate footnotes attached to advertising. Any “honeymoon” discount shorter than three years must be disclosed in the comparison calculation. Consumer groups want clearer disclosure of how much a 0.25 percentage point RBA move translates into monthly dollars for the median loan size in each state.
Until the board signals a pause, the practical advice from non-bank lenders is unchanged: stress-test budgets at 4.85 percent even if the advertised rate is lower, and treat cash-back offers as marketing unless the comparison rate still beats your existing deal after fees.
