Refinancing is one of the few money moves where the payoff shows up in your very next repayment. It is also the one Sydney homeowners put off the longest, usually because nobody has given them a straight answer on what the switch actually costs.
Here is that answer.
Short version. Refinancing a home loan in Australia in 2026 usually costs $500 to $2,000 in upfront switching fees. On a NSW property, $365.46 of that is fixed government registration charges. Your current lender adds a discharge fee, typically $150 to $400. Application fees, valuation fees and settlement fees are negotiable, and the incoming lender often waives them to win your business. The wildcard is break costs on a fixed loan, and in the current rate environment those are frequently nil.
Last updated August 2026. The Reserve Bank held the cash rate at 4.35% on 11 August 2026, its second consecutive hold after three increases in the first half of the year. That matters for what refinancing costs you, and we come back to why in the break costs section.
What refinancing actually costs: every line item
Not every line applies to every borrower, which is why the total swings so widely.
| Cost | Typical 2026 range | Who charges it | Negotiable? |
|---|---|---|---|
| Discharge fee | $150 to $400 | Your current lender | No |
| Mortgage discharge registration (NSW) | $182.73 | NSW Land Registry Services | No |
| New mortgage registration (NSW) | $182.73 | NSW Land Registry Services | No |
| Application or establishment fee | $0 to $600 | New lender | Yes, often waived |
| Property valuation | $0 to $300 | New lender | Yes, often waived |
| Settlement or legal fee | $0 to $300 | New lender | Sometimes |
| Ongoing package or annual fee | $0 to $395 per year | New lender | Yes |
| Lenders Mortgage Insurance | Thousands, if it applies | New lender's insurer | No |
| Break cost on a fixed loan | $0 to five figures | Your current lender | No |
Discharge fee. Your current lender charges this for releasing its mortgage over your property. It is not a penalty and it is not avoidable, though the amount varies. The major banks generally sit at the top of that $150 to $400 band and smaller lenders sit lower. Get the exact figure in writing before you start, because it goes straight into your break-even sum.
Application or establishment fee. Charged by the lender you are moving to, and the single most negotiable cost in the process. Plenty of lenders run permanent fee-free refinance offers, and a broker can usually get it waived even where it is advertised.
Valuation. On a straightforward owner-occupied house in an established Sydney suburb, most lenders accept a desktop valuation and charge nothing. You are more likely to pay when the property is unusual, rural, or being valued above a lender's automated confidence range.
Ongoing fees. Not a switching cost, but it belongs in the comparison. A package loan with a $395 annual fee needs to return more than $395 a year through the rate discount and offset account, or a basic no-frills product wins. Our home loan offset calculator is the quickest way to test whether the offset earns its keep.
The two NSW government fees nobody warns you about
When you move your loan to a new lender, two dealings get lodged with NSW Land Registry Services. One discharges the old mortgage over your title. One registers the new one.
For the 2026/27 financial year, NSW Land Registry Services charges $182.73 including GST for each of those dealings. That is $365.46 in unavoidable government charges on a standard NSW refinance, before any lender has charged you a cent.
The fee is flat. It is the same on a $400,000 mortgage in Blacktown as on a $2.5 million mortgage in Bella Vista, which makes it trivial on a large loan and annoying on a small one. And if you refinance internally with your existing lender, a product switch rather than a lender switch, you usually avoid both fees entirely because the mortgage on title never changes hands.
Break costs: the line item that can blow up the plan
If you are on a variable rate, skip this section. Break costs only apply to fixed-rate loans exited before the fixed term ends.
A break cost is not a fee the lender invents. When you fix, the lender funds your loan at a matching wholesale rate for that term. If you leave early, the lender has to unwind that funding position, and the break cost is its economic loss on the unwind. The direction of rates since you fixed decides everything.
- If wholesale rates have fallen since you fixed, the lender can only re-lend your money at a lower rate. It has lost money, and your break cost can be substantial. ASIC's Moneysmart guidance illustrates break costs running from zero to over $15,000 on a $500,000 loan, depending on the size of the move and how much of the term is left.
- If wholesale rates have risen since you fixed, the lender can re-lend at a higher rate. There is no loss to recover, so your break cost is usually nil or close to it.
If you are weighing whether to fix again at the other end, our guide to fixed rate versus variable rate home loans walks through the trade-off.
The break-even calculation, done properly
Break-even is the only number that matters. It answers one question: how many months of savings does it take to repay the cost of switching?
Total switching cost divided by monthly saving equals break-even in months.
Here is a real Hills District scenario. Owner-occupier in Kellyville, loan balance $750,000, 25 years remaining, principal and interest, LVR around 65%, variable rate. Currently paying 6.39% p.a. and moving to 5.84% p.a., a gap of 0.55%. Both rates are market reference points drawn from advertised owner-occupier variable rates in August 2026, not a specific lender offer.
| Current loan | New loan | |
|---|---|---|
| Rate | 6.39% p.a. | 5.84% p.a. |
| Balance | $750,000 | $750,000 |
| Term remaining | 25 years | 25 years |
| Monthly repayment | $5,013 | $4,759 |
Monthly saving: $253. Annual saving: about $3,040.
Now the switching cost, run two ways.
| Cost item | Best case (fees waived) | Worst case (nothing waived) |
|---|---|---|
| Discharge fee | $350 | $350 |
| NSW discharge registration | $182.73 | $182.73 |
| NSW mortgage registration | $182.73 | $182.73 |
| Application fee | $0 | $600 |
| Valuation | $0 | $300 |
| Settlement or legal fee | $150 | $300 |
| Total | $865 | $1,915 |
Best case break-even: $865 divided by $253 equals 3.4 months.
Worst case break-even: $1,915 divided by $253 equals 7.6 months.
Either way this borrower is in front within the year and roughly $3,040 a year better off after that. Over five years that is more than $15,000, and more again if they hold the repayment steady at the old $5,013 and let the extra $253 attack the principal. Run your own version through our loan repayment calculator first. If the break-even lands under 12 months, the switch is almost always worth doing.
When the costs outweigh the savings
Refinancing is not automatically the right call. These are the cases where we tell Sydney clients to stay put, at least for now.
Your loan balance is small. The government fees are flat, so they bite harder on a small loan. On a $120,000 balance with 6 years left, a 0.55% cut saves about $30 a month, and a $900 switching cost takes two and a half years to recover.
Your LVR is above 80%. A new lender means a fresh valuation and fresh Lenders Mortgage Insurance if you land above 80%. LMI is not portable between lenders, and paying it twice will swamp any rate saving. Read how to avoid LMI in Sydney before you apply.
You have a large break cost. If breaking a fixed loan costs $8,000 and the switch saves $250 a month, break-even is over two and a half years, often longer than the remaining fixed term.
Your circumstances changed recently. Refinancing is a full new credit application. If you have changed jobs in the last three months or taken on a car loan, fix the file first, then switch.
You are about to sell. Inside 12 months the switching cost will not be recovered, and most cashback offers claw back if you discharge early.
How Sydney borrowers cut the switching cost to near zero
There are four levers, and most people only pull one.
1. Ask your current lender first. A repricing request costs nothing and avoids all $365.46 of government fees plus the discharge fee. Lenders keep a retention discount in their back pocket for exactly this call. If what they offer gets you within about 0.15% of the best external option, staying is usually cheaper once switching costs are counted.
2. Make the new lender absorb the fees. Application fee waivers, free valuations and covered settlement fees are standard competitive tools right now, not favours.
3. Use a cashback offer if one genuinely fits. Several lenders are running refinance cashbacks in 2026, from $2,000 to $4,000, which can turn a $900 switching cost into a day-one gain. It can also trap you in an uncompetitive rate. We break the maths down in our guide to refinance cashback offers.
4. Time the switch to your fixed roll-off. Wait until a fixed term expires and there is no break cost at all. Lenders will happily book a refinance to settle on the roll-off date. Our guide on when to refinance covers the other timing triggers worth watching.
What we see across the Hills District
Two patterns show up almost every week with clients in Castle Hill, Baulkham Hills, Kellyville and Norwest.
The first is loyalty tax. Borrowers who have been with the same lender four or more years without asking for a review are routinely paying 0.40% to 0.70% above what that same lender offers a new customer for the identical product. Nothing about the loan changed. The discount simply stopped being applied.
The second is unused equity. Hills District values mean plenty of owners who bought at 90% LVR now sit below 70%, which unlocks a lower rate tier at most lenders. If you want to put that equity to work rather than just cut your rate, our guide to refinancing an investment property loan covers the investor version.
If you want a broker to price your loan against the market, our refinancing service exists for that. We work with owners right across the Hills District.
See what your refinance actually costs
Every number above changes with your lender, balance, LVR and whether any part of your loan is fixed. The itemised list tells you what to ask for. A broker tells you what you will actually pay.
We will pull your current rate, price it against the lenders we are accredited with, quote the switching cost line by line, and give you the break-even in months. If the answer is that you should stay put and ask your bank for a discount, we will tell you that too.

Quick answers
Frequently asked questions
Most borrowers pay $500 to $2,000 in total switching costs. On a NSW property, $365.46 is fixed government registration ($182.73 to discharge the old mortgage and $182.73 to register the new one for 2026/27). Your current lender adds a discharge fee of roughly $150 to $400. Application, valuation and settlement fees make up the rest and are frequently waived. If you exit a fixed rate early, add the break cost.
Usually yes on a loan of any real size. On a $750,000 balance with 25 years to run, a 0.55% cut saves about $253 a month, roughly $3,040 a year. Against a switching cost of $865 to $1,915 that pays for itself in three to eight months. Our rule: if break-even is under 12 months, refinance. On a small balance or short remaining term, the same 0.5% may not clear the fees.
No. NSW abolished mortgage duty on refinances, so there is no stamp duty when you move an existing loan to a new lender over the same property. You pay the two NSW Land Registry Services dealing fees of $182.73 each. Stamp duty only returns if the property itself changes hands or ownership shares change.
Yes, but you will be quoted a break cost. Ask for it in writing before you commit, because it is calculated on the day and moves. In the current environment the news is often better than expected: because rates rose through 2026 rather than fell, borrowers who fixed at low 2025 rates may face little or no break cost.
Plan for four to six weeks from application to settlement, though a well-prepared file at a fast lender can settle in two to three weeks. The main delay is your existing lender's discharge process, which commonly takes ten to fifteen business days on its own. Lodge the discharge authority early.
A refinance creates a credit enquiry, and enquiries have a small short-term effect. One or two is a non-event. The damage comes from applying to five lenders at once, which reads as financial stress to an assessor. Work out the right lender first, then apply once.
Yes, and it is the most common reason people refinance beyond chasing a rate. Increasing the loan against a property that has risen in value is called cash-out or equity release. The lender will want the purpose, and above certain amounts will ask for evidence such as a renovation quote. Staying at or under 80% LVR avoids LMI on the increase.
Ask them first, always. It costs nothing and avoids the entire $365.46 in government fees plus the discharge fee. If your lender comes back within about 0.15% of the best external offer, staying is often cheaper once switching costs are counted. If they will not move, you have lost nothing.
Frequently yes. Cashbacks running in 2026 sit between $2,000 and $4,000, which comfortably clears a $900 to $2,000 switching cost. The catch is the rate attached to the product and the clawback conditions, which commonly require you to keep the loan 12 months. A cashback on a rate 0.25% too high costs you more than it pays inside three years.
