Every major Australian lender is offering refinance cashback in mid-2026. The headline numbers are real: $1,500 to $4,000 paid to your nominated account after settlement. The marketing is everywhere. The mortgage broker associations have flagged refinance volumes as the strongest in three years partly because of these offers.
Three things are also true about most of these offers that the marketing pages do not mention with the same enthusiasm: most include claw-back clauses, most include rate reset clauses, and most are calibrated so the lender breaks even on the cashback within 18 to 24 months. The cashback is paid for. It is paid for by you, just not in a way that shows on the day of settlement.
What claw-back actually means
A claw-back clause says: if you discharge the loan within a defined period (typically 2 to 3 years), the lender claws back the cashback. Sometimes the full amount, sometimes pro-rated.
The practical implication: the cashback is a loan from the lender, not a gift. The repayment is the obligation to stay with that lender for the claw-back period. If you refinance again within that window (because rates have moved sharper somewhere else, or because the lender resets your rate higher after year one), you give the cashback back.
CBA, Westpac, NAB, ANZ, ING and the major non-bank lenders all have some form of claw-back on most of their refinance cashback offers in 2026. The specific terms vary materially: CBA typically uses a 2-year claw-back; Westpac and NAB lean towards 3 years; ANZ varies by offer; some non-bank offers have no claw-back at all (which is one of the cleanest tells for which offers are genuinely competitive).
The rate reset trap
Worse than claw-back is the rate reset clause, which is more common than most borrowers realise. The structure: the headline rate that gets advertised on the offer applies for 12 or 24 months. After that period the rate resets to the standard variable, often 30 to 50 basis points higher.
On a $700,000 loan, a 40 basis-point rate reset is $233 per month or $2,800 per year. After year 2 the borrower is paying the full standard variable. The cashback of $3,000 was effectively a discount on year-one interest cost that gets clawed back through higher rates from year 2 onwards.
The maths is straightforward. The lender pays you $3,000 upfront. The lender recovers $2,800 a year in extra interest from year 2 onwards by holding you on a rate that is 40 basis points above what they would have offered without the cashback structure. The cashback breaks even in about 13 months of post-reset interest. The lender keeps you for another 7 to 10 years at the higher rate. Net to the lender: $15,000 to $25,000 of additional interest over the loan life.
The conditions that are reasonable
Not every cashback offer is structured to trap you. A material minority are genuinely good deals. The conditions that distinguish a clean offer from a marketing trap:
- No claw-back, or claw-back only in the first 12 months.
- No rate reset; the offered rate applies for the loan life or at least 24 months without an automatic reset.
- The rate itself is competitive on a like-for-like comparison against non-bank alternatives (Athena, ING Mortgage Simplifier, Macquarie Basic, Tic:Toc) before the cashback is factored in.
- The annual fees, if any, are reasonable for the package (Wealth Package and Premier Advantage fees of $395-400 are standard; anything above that on a refinance package is excessive).
- No requirement to maintain specific other products (transaction account, credit card) for the claw-back period.
A clean offer that meets all five tests is a genuine cashback. A clean offer that fails one or two of the tests can still be the right call for some borrowers but the maths needs to be modelled. An offer that fails three or more of the tests is a marketing trap.
Specific lender offers in mid-2026 (named)
As at early June 2026, the cashback landscape included (this changes, check current at application stage):
- CBA: $3,000 cashback on refinance to packaged variable. 2-year claw-back. Rate competitive against Wealth Package standard.
- Westpac: $2,000 to $4,000 cashback depending on loan size. 3-year claw-back. Rate at Premier Advantage standard tier.
- NAB: $3,000 cashback on Tailored Home Loan and Choice Package refinance. 3-year claw-back. Rate at standard package tier.
- ANZ: $2,000 cashback, with some specific product variants offering more. Claw-back terms vary by product.
- ING Mortgage Simplifier: smaller cashback (around $1,500) but no claw-back and sharp underlying rate.
- Athena: no cashback, no claw-back, but consistently sharp variable rate without an annual fee.
- Macquarie Basic: occasional cashback (typically $2,000), short claw-back periods, competitive rate.
The lender list above is not exhaustive and the terms change. The point is the pattern: Big 4 offers tend to combine larger cashback with longer claw-back and packaged rate; non-bank offers tend to combine smaller cashback (or none) with cleaner rate and no claw-back. The non-bank model is typically better value over the loan life for prime borrowers; the Big 4 cashback model can be better for borrowers who definitely intend to stay with the same lender for 3+ years.
The honest test before signing
Three questions before accepting any refinance cashback offer:
- What is the claw-back period and exact amount? Get this in writing from the lender, not from the marketing page.
- Does the rate reset higher after a defined period? If yes, model the rate over the full claw-back period plus 12 months. If the total interest paid is materially above what a no-cashback alternative would cost over the same period, the cashback is paying for something you are buying back.
- Is the rate genuinely competitive against the cleanest non-bank alternative at the time? Athena, ING Mortgage Simplifier and Macquarie Basic are the standard reference points. If the cashback-offered rate is 20+ basis points above the cleanest non-bank, the cashback is the lender buying the rate gap.
A broker on a wide panel can model all of this in minutes. The lender retention desk can also confirm the actual claw-back and rate reset terms. Do not rely on the marketing.
