Key facts about Westpac’s rate changes

What is Westpac’s current variable rate?

Westpac’s advertised variable rates depend on the product, loan-to-value ratio, and whether you hold a Premier Advantage Package. After the two 0.25% cuts in 2025, the lowest rate available from Westpac for owner‑occupiers paying principal and interest is 5.34% p.a. on the Flexi First Option Home Loan, according to Mozo’s June 2026 comparison.

Westpac variable rate for owner occupiers with package discount

• Rocket Loan with Premier Advantage Package (LVR ≤70%): 5.34% p.a. (variable) – Mozo
• Standard variable rate without package: higher, typically around 7.29% as of April 2025 before cuts Westpac
• Investors with package: advertised at 6.44% p.a. after April 2025 changes

Westpac variable rate for investors

After the April 2025 advertised-rate reduction, Westpac’s packaged variable rate for investors dropped to 6.44% p.a. Westpac. The further May 2025 cut brought investor rates down again, though exact current rates vary by LVR and product.

The pattern: Westpac has aggressively repriced its variable book to grab market share, especially among owner‑occupiers with good equity. For investors, the gap remains wider — about 1.1 percentage points above the best owner‑occupier rate.

Is Westpac passing on the interest rate cut?

Yes — fully. Westpac passed on the entire 0.25% RBA cut in March 2025 to both new and existing customers Westpac. It was the first of the Big Four to announce the pass-through. The same full pass-through applied after the May 2025 cut, though Westpac was the last Big Four bank to implement the change, with an effective date of 3 June 2025 Canstar.

Westpac’s March 2025 rate cut announcement

On 18 February 2025, Westpac said it would lower variable home loan rates by 0.25% p.a., effective 4 March, for new and existing customers. The bank calculated that a borrower with a $500,000 principal-and-interest loan would save about $90 per month, or $1,080 per year Westpac.

Comparison with Commonwealth Bank pass-through

CBA also passed on the full 0.25% cut, effective 31 March 2025, and later matched the May cut. By June 2026, both CBA’s Digi Home Loan and Westpac’s Flexi First Option sat at 5.34% variable, making them equal lowest among the Big Four Mozo. The difference: Westpac’s rate applies across a broader range of loans, while CBA’s Digi is an online-only product with no offset.

The trade-off: Westpac’s full pass-through is good news for borrowers, but savers have seen deposit rates fall faster, narrowing the gap between home loan rates and term deposits.

Will mortgage rates drop to 3% again?

The era of 3% variable mortgage rates in Australia was a pandemic anomaly, driven by emergency RBA settings in 2021-2022. Most economists expect the cash rate to stay above 4.0% through 2025, and a return to 3% variable rates looks unlikely in the near term.

Economic outlook for cash rate in 2025-2026

After the May 2025 cut, the RBA cash rate sits at 4.10%. Major bank forecasts suggest one or two more cuts by mid-2026, but the terminal rate is projected around 3.5-3.6% — still far above the pandemic floor of 0.10%.

Historical context: lowest variable rates in Australia

In November 2024, Westpac’s lowest variable rate was 6.44% MPA Mag. By June 2026, it had fallen to 5.34% — a drop of 1.1 percentage points. Even so, 3% rates are not on the horizon; they would require the RBA to cut by another 1.5-2.0 percentage points, which most economists rule out without a sharp economic downturn.

What this means: If you’re waiting for 3% variable rates to appear again, you may be waiting years. The current 5.34% is historically low compared to the 6-7% rates of late 2023.

Should I fix for 2 or 5 years now?

With variable rates now lower than fixed rates, the usual advice — fix for certainty when variable rates are rising — has flipped. As of August 2025, Westpac’s 2-year fixed rate is approximately 5.99% p.a. and its 5-year fixed rate is around 6.29% p.a., both above the variable rate of 5.34%.

Westpac fixed rates compared to variable

• Variable (lowest): 5.34% p.a.
• 2-year fixed: ~5.99% p.a.
• 5-year fixed: ~6.29% p.a.

Fixing locks in a higher rate now in exchange for protection against future increases. The premium for 2 years is about 0.65 percentage points; for 5 years it’s nearly 1 point.

Pros and cons of 2-year vs 5-year fixed rate

The implication: For borrowers who believe rates will continue to fall, the variable rate is the clear winner now. But if you value certainty and expect the RBA to reverse course, a 2-year fix at ~5.99% is a modest insurance premium.

What is the cheapest home loan interest rate offered by Westpac?

Westpac’s cheapest home loan rate is 5.34% p.a. variable on the Flexi First Option Home Loan, as reported by Mozo. This rate is available to owner‑occupiers with an LVR of 70% or less who pay principal and interest.

Rocket Loan variable rate with offset

The Rocket Loan with Premier Advantage Package also offers the same 5.34% rate if you meet the LVR criteria, but it adds an offset account for a $395 annual fee. The comparison rate is slightly higher due to fees.

Premier Advantage Package discount

Westpac’s package discounts reduce the standard variable rate by roughly 1.05 percentage points (the April 2025 reduction) Westpac. Without the package, the standard variable rate is materially higher.

The catch: The cheapest 5.34% rate excludes investors, interest-only loans, and anyone with LVR above 70%. For those borrowers, the next best is the packaged investor rate at 6.44% (before the May cut).

Big Four variable rate comparison

The rate board shows a clear tier among Australia’s largest lenders.

The pattern: Westpac and CBA are neck-and-neck at the low end, while NAB and ANZ lag by 0.30-0.40 percentage points. Westpac’s broader eligibility (not limited to online‑only) gives it a slight edge for borrowers who want an offset account.

FAQ

For Australian mortgage holders: the choice is clear: switch to Westpac’s 5.34% variable if you have equity, or watch your bank’s rate cut announcements if you’re with NAB or ANZ.
