Westpac increased variable home-loan reference rates by 25 basis points on Friday 9 October, lifting its lowest advertised owner-occupier variable rate to 6.24 percent and ending an era in which any major bank headline mortgage rate still began with a five. The change mirrors identical moves at Commonwealth Bank, ANZ and NAB, completing the pass-through of the Reserve Bank’s 29 September cash-rate hike to 4.60 percent.

What borrowers pay now

PerthNow reported that CBA’s comparable variable rate now stands at 6.34 percent, ANZ between 6.29 and 7.04 percent depending on product tier, and NAB in a similar band. Westpac’s 6.24 percent figure applies to its lowest advertised package with qualifying discounts; many customers on legacy products pay more. Nathan Price, who writes on household credit for InfoHandle, said the spread between advertised and actual rates widened during the hiking cycle as banks tightened discount eligibility.

Monthly payment arithmetic

A household with a $750,000 variable loan at a prior 5.99 percent rate faces roughly $115 more per month after a 0.25 percentage point rise, before tax effects on offset balances. Borrowers who fixed portions of their debt escape today’s change until those terms expire, when revert rates near 7 percent have been common in broker quotes. First-home buyers who entered in 2022 with low-deposit loans are particularly exposed because loan-to-value ratios remain high.

Westpac also adjusted some deposit rates upward, but the income gain on typical savings balances is far smaller than the mortgage hit, reinforcing the RBA’s intent to slow consumption via the borrowing channel.

Why banks moved the same day

All four majors announced effective dates of 9 October after the RBA’s Tuesday board meeting, avoiding the staggered pass-through that drew political criticism in earlier cycles. Treasurer Jim Chalmers urged banks to balance borrower and depositor interests; consumer groups asked for hardship pathways for customers who booked rate-sensitive purchases assuming a pause.

Westpac’s announcement noted the change applies to variable owner-occupier and investor loans, with business lines repriced on separate schedules. Line-of-credit products tied to residential security move in tandem, affecting small landlords using home equity to fund renovations.

Refinancing window

Comparison sites updated within hours, showing non-bank lenders still advertising sub-6 percent headline rates for pristine credit files, though those offers often carry fees or revert higher. Mortgage brokers in Brisbane and Perth reported a spike in refinance inquiries from customers who fixed two years ago and now face rolling into variable rates above 6 percent.

The Australian Prudential Regulation Authority’s latest household debt metrics show most borrowers remain ahead on repayments, but delinquencies ticked up in outer suburban postcodes where newer loans cluster.

Credit cards and personal loans

While this repricing targets mortgages, the same funding shock eventually flows into personal loan and credit-card margins. Westpac did not change card purchase rates on Friday, but prior cycles suggest re-pricing notices may follow if funding costs stay elevated. Customers consolidating card debt into home loans should factor in the higher mortgage rate before extending tenure.

Hardship and fixed-rate cliffs

Banks reiterated existing hardship programs: payment pauses, term extensions and temporary interest-only periods remain available on application. Financial counsellors warned that waiting until after arrears appear reduces options. Customers with offset accounts should confirm funds are linked correctly so every dollar reduces interest charged at the new rate immediately.

Policy context

The RBA board said further hikes remain possible if inflation stalls above target. Money markets now price a November increase at roughly 20 percent, down from higher odds last week. If the board pauses, mortgage rates may still not fall until banks compete for slower loan growth—cold comfort for households repricing today.

Practical steps

Check your notice letter for the exact reference rate and effective date; online banking displays can lag 24 hours. If you are within a few months of regaining a loyalty discount, ask whether Friday’s move affects the discount base or only the headline table. For Westpac customers at 6.24 percent on paper, the real task is whether household income grew 25 basis points faster than expenses since the last hike—if not, the budget trim starts this weekend.
