What are the current interest rates for home loans in Australia?

Australian mortgage rates remain elevated, with Westpac’s variable products clustered around 6% p.a.

Westpac Australia standard variable rate

Westpac’s advertised package variable rate for owner‑occupiers was 6.24% p.a. as of April 2025 (70–80% LVR), while the Online Home Loan basic variable rate for refinancers was 5.84% p.a. Source: Westpac AU media release

Comparison to other major banks

Westpac’s rates are broadly in line with CBA, NAB, and ANZ, though special offers such as the Online Home Loan can undercut competitors on certain LVR bands.

Effect of RBA cash rate

The RBA cash rate stands at 4.35% as of early 2025. Westpac’s variable rates are typically 1.5–1.9 percentage points above the cash rate, reflecting the bank’s cost of funds and profit margin.

“The RBA has indicated the cash rate may stay higher for longer to curb inflation.” – RBA Governor, public statement, 2025.

Will mortgage rates ever be 3% again?

Mortgage rates below 3% were common in 2021, but current conditions make a return unlikely in the near term.

Historical rate context

In 2021, Westpac AU offered variable rates as low as 2.29% p.a. and fixed rates below 2%. Today, the lowest variable rate is roughly 5.84% p.a.

Economist predictions

Most economists expect the RBA to begin cutting rates in late 2025 or 2026, but forecasts suggest the cash rate may bottom out around 3.5% – meaning mortgage rates would still be above 5%.

Impact of inflation and central bank policy

Persistent inflation (above 3% in both Australia and New Zealand) keeps central banks cautious. Until inflation sustainably falls to target, mortgage rates are unlikely to approach 3%.

Warning: Do not bank on a return to 3% rates. Budget for current rates and factor in a potential rise if inflation re‑accelerates.

How much will I repay on a $400,000 mortgage in New Zealand?

Using Westpac NZ’s current special rates, repayments can be estimated easily.

Using Westpac mortgage calculator

Westpac NZ’s online calculator allows you to input loan amount, term, and rate. It produces a repayment schedule including interest and fees.

Sample repayment amounts at current rates

At the 1‑year special rate of 4.89% p.a., monthly principal‑and‑interest payments on a $400,000 loan over 30 years are approximately $2,114. At the standard 1‑year rate of 5.49%, the payment rises to about $2,264.

Impact of rate changes

A 0.25% increase in the rate adds roughly $13 per month per $100,000 borrowed, highlighting the benefit of fixing now while special rates remain low.

What this means: A New Zealand borrower who fixes at 4.89% for one year saves about $150 per month compared to the standard rate – that’s $1,800 annually.

Fixed vs Variable: Which Should You Choose?

Upsides

  • Fixed: predictable payments for budgeting
  • Variable: can fall if rates drop; often lower initial rate

Downsides

  • Fixed: no benefit from rate cuts; break costs if refinancing
  • Variable: payments can increase unexpectedly

The decision depends on your risk tolerance and cashflow. With Westpac offering both fixed and variable options, a split loan may suit those who want both certainty and flexibility.

Frequently Asked Questions

What is the difference between fixed and variable home loan rates?

Fixed rates lock in a set interest rate for a period, ensuring constant repayments. Variable rates fluctuate with market conditions, meaning payments can change.

How often do Westpac home loan rates change?

Variable rates can change at any time based on Westpac’s funding costs and the RBA cash rate. Fixed rates are updated when the bank reviews its product pricing, typically every few months.

Can I negotiate a lower interest rate with Westpac?

Yes, especially if you have a strong credit history or a large deposit. Existing customers may also receive loyalty offers. Mention competitor rates to strengthen your position.

What is the Westpac Rocket Repay offset account?

The Rocket Repay home loan includes an offset account that reduces interest‑payable daily. It is not currently listed in Westpac’s main rate tables, but older products may still be accessible.

Are there fees for early repayment on Westpac home loans?

Fixed rate loans incur break costs if repaid early. Variable loans have no early repayment fees (except possible discharge fees). Check your contract for exact terms.

How do I apply for a Westpac home loan?

Applications can be made online, by phone, or in branch. Pre‑approval is recommended before making an offer on a property.

Does Westpac offer construction loans?

Yes, Westpac offers construction loans for building a new home. These typically have a variable rate and require progress payments.

How does the Westpac mortgage repayment calculator work?

The calculator uses loan amount, term, interest rate, and repayment frequency to estimate monthly or fortnightly payments. It is available on the Westpac website.

Bottom Line

Westpac’s home loan rates vary greatly by jurisdiction: Australian borrowers face variable rates near 6% while New Zealanders can fix below 5%. The catch is that New Zealand’s special rates are temporary and may not be available to all LVR bands. Older borrowers should confirm that loan terms meet their pension income. The implication for borrowers: act quickly on special rates in NZ, and consider a split loan in AU to hedge against rate rises.
