Refinance Your Home Loan in Australia: Should You Switch or Renegotiate in 2026?

Written by David Palummo, MFAA-accredited Mortgage Broker at IQ+ Loans August 2026

If you've felt your mortgage repayments creep up over the past few months, you're not imagining it. The Reserve Bank lifted the cash rate to start 2026, and further movement has been on the table at almost every meeting since. For a lot of borrowers, the loan that felt comfortable twelve months ago suddenly doesn't.

Here's the good news: you're not stuck. Whether you stay with your current bank and ask for a better deal, or move your loan somewhere new altogether, there has rarely been a better, or more necessary, time to take a hard look at your home loan. Refinancing activity in Australia is at record levels, and for good reason.

This guide walks through exactly what's happening in the market, how to tell if you're paying more than you should be, and the practical steps to renegotiate or refinance in 2026.

Why Refinancing Is Surging in Australia Right Now

Owner-occupiers switched a record amount in home loans to a new lender in the March quarter of 2026 alone, and internal refinancing where borrowers renegotiate with their existing lender rather than leave grew even faster, up over 30% year-on-year by value. Put simply: hundreds of thousands of Australians have already decided it's time to check their rate, and they're not wrong to.

More than 640,000 home loans were refinanced nationally last year. Refinancing now accounts for around a third of all residential lending activity in Australia, up sharply from just a couple of years ago. That's not a niche trend it's become standard financial housekeeping, in the same category as reviewing your health insurance or comparing energy providers.

The reason is straightforward. As the cash rate has moved, lenders haven't treated all their customers equally. New customers walking in the door are consistently offered sharper rates than existing customers who've simply stayed put. Industry analysis in 2026 shows existing customers at the big four banks often pay somewhere between 0.30% and 0.50% more than a new customer would be offered for an identical loan, at the identical bank. On a $600,000 loan, that gap alone can add well over $1,500 a year in extra interest for changing nothing except staying loyal.

Some in the industry call this the "loyalty tax." It exists because banks compete hard to win new customers, and rely on existing customers not going to the trouble of checking. Data from the Mortgage & Finance Association of Australia backs this up, showing that borrowers who switch lenders save an average of close to $2,000 a year.

Internal Refinancing vs External Refinancing: What's the Difference?

‍ When people say "refinance," they usually mean one of two quite different things, and it's worth being clear on the distinction before you do anything.

Internal refinancing means staying with your current lender but renegotiating your rate, restructuring your loan, or switching products. This is often the fastest and lowest-friction option — a phone call and some paperwork rather than a full application. It's ideal when you like your lender's service and features (offset accounts, redraw, a banking relationship you value) but you know you're not on their sharpest rate.

External refinancing means moving your loan to a completely new lender. It takes more effort a new application, a new valuation, discharge paperwork with your old lender but it opens up the whole market rather than just what one bank is willing to offer you. This is usually where the bigger savings live, because you're no longer negotiating from a position of "please don't leave me," you're the new customer everyone wants to win.

Both are surging right now. Internal refinancing added tens of billions of dollars in loan value in the first few months of 2026 alone, growing even faster than external switching which tells you that a lot of borrowers are starting with the easy conversation (call your bank) before deciding whether it's worth going further.

Five Signs It's Worth Reviewing Your Loan

Not everyone needs to refinance. But if any of the following sound familiar, it's worth at least having the conversation.

You haven't reviewed your rate in over a year. Lending is a fast-moving, competitive market. A rate that was sharp when you settled can quietly become uncompetitive within twelve months, without you ever being told.

You're coming off a fixed rate. Borrowers who fixed during the low-rate period are rolling onto variable rates that can be significantly higher than what's currently available elsewhere. This is one of the single biggest triggers for refinancing activity right now.

Your repayments have started to bite. If the recent rate rises have genuinely strained your monthly budget, that's not something to just absorb, it's a signal to actively look for a better structure, not just a better rate.

You're carrying other debt alongside your mortgage. Credit cards, car loans, and personal loans typically carry much higher interest rates than a home loan. Consolidating these into your mortgage, where appropriate, can meaningfully reduce your total monthly outgoings, see our debt consolidation service page for how this works, though it's worth doing carefully, since spreading short-term debt over a 30-year term has trade-offs worth talking through.

Your circumstances have changed. A pay rise, a new job, paying down other debt, or simply building more equity in your home can all open the door to better loan options than you qualified for originally.

How Does Refinancing Work in Australia?

If you decide it's worth exploring, here's the general shape of the process. It's more straightforward than most people expect.

1. A quick financial health check. This is where a broker earns their keep, a look at your current loan, your goals (lower repayments? Access to equity? Debt consolidation? Fixed for certainty?), and whether refinancing genuinely stacks up once costs are factored in.

2. Comparing the market. Rather than you calling around a dozen banks, this is about lining up options across dozens of lenders side by side, rate, fees, features, and how each lender will actually assess your situation.

3. Application and valuation. Your new lender will assess your income, expenses, and the property itself, usually via a formal valuation. This is also where serviceability comes in, even if you're simply moving to a cheaper repayment, lenders still need to assess you against their own criteria and the standard serviceability buffer.

‍ ‍4. Approval and discharge. Once approved, your new lender pays out your existing loan, and your old lender formally discharges it. Settlement timeframes have actually been improving, average refinance settlements in 2026 have been running noticeably faster than they were just a couple of years ago, often within about three to four weeks.

‍ ‍5. You start fresh, hopefully on better terms. New rate, potentially new features, and in a lot of cases, a lower repayment from day one.

Refinancing Costs in Australia (and How Much You Could Save)

‍ ‍Refinancing isn't free, so it's worth being upfront about the numbers rather than only talking about the upside.

‍ ‍Typical costs to switch lenders can include a discharge fee from your old lender, a small government registration fee, and sometimes an application or valuation fee with the new lender, often totalling somewhere around $1,000 all up, though it varies. Many lenders also run cashback offers for refinancers that can offset some or all of this, particularly in a competitive market like the current one where banks are actively fighting for switchers.

‍ ‍On the savings side, borrowers who refinanced in early 2026 achieved rate reductions averaging around 0.68%, translating to average monthly savings in the hundreds of dollars for those moving from a major bank's standard variable rate to a more competitive alternative. Over the life of a loan, even a modest rate reduction compounds into a significant amount, which is exactly why the cost of switching is usually recovered within the first year, sometimes within months.

‍ ‍The one situation worth flagging: if your equity in the property is below 20%, refinancing can trigger Lenders Mortgage Insurance again with a new lender, which can erode or even outweigh the savings. This is precisely the kind of detail that's easy to miss doing it alone, and exactly where getting advice before you apply, rather than after - matters.

‍ Why So Many Borrowers Are Going Through a Broker

‍ It's worth noting that the majority of refinanced loans in Australia, well over three-quarters, are now arranged through a mortgage broker rather than borrowers going directly to a bank. That's not a coincidence.

‍ ‍A broker isn't limited to one lender's product range or one lender's appetite for risk. Where a bank's staff can only offer you what's on their own shelf, a broker can compare your situation against dozens of lenders at once, including smaller banks, credit unions, and non-bank lenders that have been winning a growing share of switchers precisely because they're competing hard on rate.

‍ ‍It also means someone is doing the legwork of checking whether refinancing actually makes sense for you before you spend time on an application, including the less exciting parts, like whether break costs on a fixed loan outweigh the benefit, or whether your current lender might match a competitive offer if simply asked (sometimes the cheapest refinance is the one that never leaves your current bank).

Common Questions We're Getting Right Now

‍ ‍Will rates keep rising? Nobody can say for certain, economists themselves are split, with some forecasting further hikes and others expecting the RBA to hold steady as it weighs slowing growth against inflation that hasn't fully settled. Rather than trying to time the market perfectly, the more useful approach is making sure your current loan is competitive regardless of what happens next. A well-structured loan protects you either way.

‍ ‍Is it too late to refinance if rates might fall later? Not really. If a better deal is available today, waiting on the chance that an even better one might appear in six or twelve months means paying more in the meantime for a saving that isn't guaranteed. And if you do move to a lender now and rates fall further later, you're free to review again, there's no lock-in that prevents you from refinancing more than once.

‍ ‍Will refinancing hurt my credit score? A refinance application does involve a credit check, which can cause a small, temporary dip. But a single, well-considered application has a minor and short-lived impact compared with the ongoing cost of staying on an uncompetitive rate for years. The bigger risk to your credit file is applying for several loans in a short window without guidance, which is another reason to compare properly first rather than shot-gunning applications yourself.

‍ What if I'm on a fixed rate and it hasn't expired yet? You can still look into it, but breaking a fixed-rate loan early usually comes with a break cost, which can sometimes be significant depending on how much time is left on the term and how rates have moved since you fixed. This is one of the calculations worth doing properly before acting, in some cases it's worth waiting until the fixed term ends, and in others the savings from switching still outweigh the break fee. It depends entirely on your specific numbers.

‍ ‍Do I need a perfect credit history or a big deposit to refinance? No, refinancing criteria vary a lot by lender, and plenty of borrowers refinance with modest equity or an imperfect credit history. The main thing to be aware of is that if your equity is below 20%, Lenders Mortgage Insurance may apply again with a new lender, which changes the maths. This is exactly the kind of detail worth checking before applying, not after.

The Real Question Isn't "Should Everyone Refinance"; It's "Does It Make Sense for You"

‍ ‍Not every loan needs to move. Some borrowers will find their current lender is genuinely competitive, or that switching costs outweigh the benefit given how long they plan to stay in the loan. That's a legitimate outcome of a proper review too, the goal isn't to switch for the sake of switching, it's to know, with certainty, whether you're on the right deal.

‍ ‍But given where rates have moved, and given the size of the gap that's opened up between what new and existing customers are offered, it's an increasingly expensive assumption to simply assume your current loan is still your best option.

‍ ‍If you haven't had your loan reviewed in the last twelve months, or if your fixed rate is due to roll off, or your monthly repayments have started to feel tighter than they should, it costs nothing to find out where you actually stand.
