The short answer
Refinance cashback offers in 2026 typically range from $1,000 to $3,000, and they are worth switching for only when the underlying loan is also better. A cashback is a marketing lever, not a customer benefit. If the rate is 0.1% higher than the market’s best, that difference alone will wipe out a $3,000 cashback within 3 years on a $600,000 loan. The right question is not “which lender is offering the biggest cashback?” It’s “which loan gives me the best total position over the next 3 to 5 years, and is a cashback part of that offer?” This post walks through the maths, the fine print, and the traps.

What is a refinance cashback?
A refinance cashback is a lump-sum payment (usually between $1,000 and $3,000) that a lender pays you when you switch your existing home loan across to them. It’s paid on settlement of the new loan, usually within 30 to 60 days, and it’s marketed as an incentive to offset the switching costs of refinancing.
Refinance cashback offers come and go depending on where lenders are in their acquisition cycles. In 2026 they’re common but not universal. Different lenders on our panel of 60+ have run cashback promotions at different times, ranging from $1,000 up to occasional $4,000 offers on larger loans. The Reserve Bank of Australia’s (RBA) rate environment influences which lenders push cashback hardest at any given time.
Important: cashback offers change constantly. Any specific dollar figure in this post is a general range, not a live offer. For current offers, book a call and we’ll walk you through what’s actually in market this week.

Are refinance cashback offers actually worth switching for?
The honest answer is: sometimes, and only when the underlying loan is genuinely better than what you have now. Here’s why.
A cashback is a one-off payment. The interest rate on your loan applies for the entire term. Over 3 to 5 years, the rate difference between two loans almost always outweighs a $3,000 cashback. Let’s look at the numbers.
Cashback vs a lower rate: which wins over 5 years?
Assume a $600,000 loan and two competing offers:
- Offer A: $3,000 cashback, rate of 6.29%
- Offer B: No cashback, rate of 6.09%
Indicative only, based on interest-only comparison over the first 5 years for illustrative purposes.
Offer A wins for the first two years. Then the extra 0.2% starts to bite, and by year 5 Offer B is $3,000 ahead. If you hold the loan for the full 25 or 30 year term, Offer B is tens of thousands ahead.
The rule of thumb: every 0.1% of rate difference on a $600,000 loan is worth about $600 a year in interest. A $3,000 cashback covers roughly 0.2% of rate difference for 2.5 years, and nothing after that.
When is a cashback actually worth it?
Refinance cashback is genuinely worth switching for in three situations:
- The rate is competitive AND the cashback is on top. If the loan you were going to choose anyway happens to also come with a cashback, take it. That’s the ideal.
- You have a small loan (under $300,000) that you’ll pay down quickly. On smaller loans, the rate difference matters less in dollar terms, so the cashback dominates the maths.
- The switching costs are unusually high. If you’re breaking a fixed-rate loan with $2,500 in break costs, a cashback that covers those costs makes the switch financially neutral instead of a short-term loss.
When is a cashback a trap?
Refinance cashback is a trap in five common situations:
- The lender’s rate is 0.1% or more above the best available for your situation.
- The comparison rate is significantly higher than the headline rate (this indicates hidden fees).
- The loan doesn’t have the features you need (offset, redraw, split, etc.).
- There’s a clawback clause if you refinance again within 12 to 24 months (see below).
- The cashback is being used to distract you from a loan structure that doesn’t suit you.
The fine print most borrowers miss
This is where cashback offers earn their reputation. The headline is designed to be memorable. The terms are designed to be forgotten.
Clawback clauses
Many lenders will claw back the cashback if you refinance out of their loan within a set period, typically 12 to 24 months. If you take a $3,000 cashback and then refinance again 15 months later because rates have moved, the lender can demand the $3,000 back on discharge. This is common enough that it’s worth checking every single offer.
Fees on the way in and out
Some lenders that offer cashback also charge slightly higher fees. Typical fee stack: an application or establishment fee ($0 to $600), an ongoing annual package fee ($395 is common), a discharge fee at the end ($150 to $400), and standard government fees. A $3,000 cashback that comes with a $395 annual package fee is really $3,000 minus $1,975 over five years, or a net $1,025.
Comparison rate vs headline rate
The headline rate is what’s advertised. The comparison rate includes fees and reflects the true cost. On some lenders that offer cashback, the gap between the two is 0.3% to 0.5% or more. Always check the comparison rate. It’s a legal disclosure requirement under the National Consumer Credit Protection Act, but most borrowers ignore it.
Loan term reset
If you take a cashback on a fresh 30-year loan when you already have 22 years left, you’ll pay more total interest even at a slightly lower rate. Match the new term to your remaining term unless there’s a specific cash-flow reason not to.
Timing of the payment
Cashback is paid on settlement, usually within 30 to 60 days. Some lenders require you to have salary credit into the new lender’s account for a set period (often 90 days) before releasing the cashback. Read the terms.
Tax treatment
For a refinance on a principal place of residence, a cashback is not usually taxable income. For an investment property, treatment can be different and depends on your circumstances. Check with your accountant, and refer to Australian Taxation Office (ATO) guidance for your specific situation.
Refinance cashback vs a lower rate: how to actually compare
Here’s the calculation we run for every client considering a cashback offer.
Step 1: Work out the true rate difference in dollars
Take the rate difference between the cashback offer and the best comparable loan without a cashback. Multiply that by your loan balance, then by the number of years you expect to hold the loan.
Example: cashback offer at 6.29%, best comparable at 6.09%, on a $600,000 loan held for 5 years. 0.2% x $600,000 x 5 years = $6,000 in extra interest over 5 years.
Step 2: Subtract the cashback
$6,000 extra interest minus $3,000 cashback = $3,000 net cost of taking the cashback offer.
Step 3: Add ongoing fee difference
If the cashback offer has a $395 annual package fee and the alternative has a $0 annual fee, add $395 x 5 years = $1,975 to the cost.
Net cost of the cashback offer over 5 years: $3,000 + $1,975 = $4,975 more expensive than the no-cashback alternative, despite the $3,000 sweetener.
Step 4: Check clawback and switching flexibility
If you might refinance again within 24 months (rates falling, life changes), the clawback clause can make the offer even worse.
This is exactly the calculation we run in a Home Loan Health Check. Book a call if you’d like it done on your loan.
Refinance cashback on the Sunshine Coast: what we’re seeing in 2026
Across our client base on the Sunshine Coast, roughly 3 in 10 refinances we’re settling in 2026 include a cashback. That mix goes up and down as lenders cycle their offers. We’re seeing cashback more commonly on:
- Loans between $400,000 and $1,000,000 (the “sweet spot” most lenders target)
- Owner-occupier loans on principal and interest (rather than investment or interest-only)
- Borrowers with LVR below 80% (no LMI implications)
For homeowners in Maroochydore, Noosa, Mooloolaba, Buderim, Caloundra and surrounding suburbs, the cashback landscape looks the same as it does elsewhere in Queensland: it’s about the specific lender’s promotional cycle, not the geography.

How we approach cashback offers for SCFS clients
When a client asks us about a cashback offer, we do three things:
- Compare the underlying loan against our full panel of 40 lenders, ignoring the cashback initially. If the loan is competitive on its own merits, the cashback is a bonus.
- Run the 5-year maths with rate, fees, cashback, and any clawback risk factored in.
- Give you the honest answer, even if the honest answer is “the cashback is a distraction and you’re better off with a different lender.”
Our job under the Best Interests Duty (a legal obligation under the National Consumer Credit Protection Act for MFAA-accredited brokers) is to recommend what’s actually best for you. Lenders don’t have that duty. That’s the fundamental difference between talking to a broker and talking to a bank direct, and it’s covered in more depth in Mortgage broker vs bank: which is better for refinancing?.

Frequently asked questions about refinance cashback offers
Between $1,000 and $3,000 for most owner-occupier loans. Occasional larger offers appear on high-value loans. Cashback offers change frequently; check current offers with a broker.
No. At any given time, roughly a third of the major and mid-tier lenders on our panel are running a cashback offer. It shifts constantly.
For a principal place of residence, generally no. For investment properties, treatment can differ. Refer to Australian Taxation Office (ATO) guidance or check with your accountant.
Usually within 30 to 60 days of settlement. Some lenders require you to meet conditions first, such as salary crediting into an account with the new lender for a set period.
Yes, this is called a clawback clause. Many lenders claw back the cashback if you refinance out within 12 to 24 months. Always check the terms before signing.
No, not directly. The refinance application itself creates a credit enquiry, but the cashback element is not separately reported.
Almost never over the medium to long term. Every 0.1% of rate difference on a $600,000 loan is worth about $600 a year in interest. A $3,000 cashback covers roughly 0.2% for 2.5 years and nothing after that.
Usually not. Refinance cashback offers are typically reserved for switching to a new lender. Internal refinances (staying with the same lender) rarely qualify.
Generally yes. On loans under $300,000, the rate difference matters less in dollar terms, and the cashback dominates the maths.
Sometimes. Fewer lenders offer cashback on investment loans, and the maths shifts because of the tax deductibility of interest. This is a case where the calculation needs to be run specifically.
No. Sunshine Coast Financial Solutions doesn’t charge you a fee. Brokers are paid by the lender on settlement, and the cashback goes to you in full.
