Fixed Interest Rates in Australia: The Comprehensive Guide

Buying or refinancing a home can feel overwhelming with so many loan options and interest rate changes in 2025–2026. Understanding fixed home loans can save you thousands and give peace of mind. 

In this article, we explain everything you need to know about fixed home loans. You’ll learn how fixed rates work, who they suit, and strategies to secure the best deal. We cover key features, break costs, split loans, and tips for timing your fix. 

Working with a trusted mortgage broker Brisbane can help you navigate options, compare lenders, and save money on your mortgage.

Let’s dive in

A fixed rate home loan is a type of mortgage where your interest rate stays the same for a set period — usually between 1 and 5 years. Unlike variable loans, your repayments won’t rise or fall if market rates change. This gives you predictable repayments and peace of mind, especially when interest rates are uncertain.

When you lock in a fixed rate, your lender agrees to keep your interest rate unchanged for a chosen term.

While fixed rates provide stability, there are some restrictions:

Fixed rates suit borrowers who value certainty and stability. Consider a fixed loan if:

Example: Fixing a $300,000 home loan at 4.50% for 5 years ensures your repayment stays the same, even if market rates rise.

Fixed rates may not be ideal if you need flexibility or expect falling interest rates. Avoid fixing if:

Fixed interest rates are shifting again in 2025–2026, and if you’re thinking about buying or refinancing, now’s the time to pay attention. Understanding how rates have changed — and where they’re heading — can help you lock in the right deal for your situation.

During 2020–2021, fixed home loans were incredibly popular. Record-low interest rates encouraged thousands of Australians to fix their loans for 1 to 5 years, locking in certainty during uncertain times.

However, when the Reserve Bank of Australia (RBA) began aggressively lifting the cash rate in 2022 and 2023, the picture changed dramatically. Fixed loans became less attractive, and by late 2023, fewer than 5% of new borrowers were choosing them.

This was one of the sharpest shifts in borrowing preferences we’ve seen in years.

Now, the tide is turning again. With inflation easing and the RBA hinting at possible rate cuts in 2026, lenders are starting to trim their fixed rates.

This shift signals growing confidence that interest rates have likely peaked and could trend lower over the next 12–18 months.

For borrowers, this is a promising sign — but it also requires careful strategy.

That’s why many borrowers are now considering shorter fixed terms, such as 1–2 years, to balance certainty with flexibility.

Pro tip: A split home loan (part fixed, part variable) can give you the best of both worlds — steady repayments on one portion and flexibility on the other. We cover more of this in a later section.

Lenders don’t adjust fixed rates at random. Their decisions are based on factors such as:

As a result, we’re seeing increased competition among lenders heading into 2026, which is excellent news for homebuyers and refinancers alike.

Here’s how fixed and variable rates have shifted over the past five years:

The message is clear — we’re entering a new cycle.

Finding the best fixed rate home loan requires strategy, timing, and expert guidance. Here’s how to maximise your savings.

Some lenders offer cashback bonuses or loyalty discounts for new or returning customers.

Fixing your rate at the right moment can make a huge difference.

Be aware of pitfalls that can cost you money:

Choosing between a fixed and variable home loan rate can significantly affect your repayments, flexibility, and overall costs. Understanding the differences helps you make smarter financial decisions.

Consider an $800,000 home loan:

Banks offer a variety of fixed rate features, which can feel overwhelming. But knowing the key options helps you choose the right loan.

Let’s break down the most important features, what they do, and who benefits from them.

Fixed rates change daily. Without a rate lock, the rate you applied for could increase by settlement. A rate lock secures your interest rate for an extra fee. For example, if you apply at 6%, the bank guarantees you pay 6% at settlement. This protects you from market fluctuations.

Some lenders allow extra repayments on fixed loans. Limits range from a few thousand dollars to 5% of the original loan. Extra repayments reduce interest over time. However, exceeding your limit may trigger fixed break costs. Always confirm your lender’s rules before paying extra.

Redraw allows you to access extra repayments you’ve made. But not all lenders treat this the same way. With some fixed loans, withdrawing funds may break your fixed contract and incur large fees. Use redraw carefully if you expect to need funds.

This feature is ideal for property investors. It allows you to prepay interest before 30 June, creating tax deductions in bulk. Some lenders offer discounts up to 0.20% on your fixed rate. It’s a smart strategy for cash flow management and tax planning.

Offset accounts reduce the interest you pay. Most banks allow partial offsets on fixed loans. A few lenders offer 100% fixed rate offsets, letting you fully reduce interest while keeping access to your funds.

Some lenders allow a fixed rate on construction loans. This gives certainty over repayments while your home is being built.

A split loan combines fixed and variable portions. This gives stability on part of your loan while retaining flexibility on the rest. It’s an effective strategy for borrowers who want the best of both worlds.

Pro Tip: Always check which features are available for your chosen lender. Speak to a Hunter Galloway mortgage broker to tailor the right fixed rate loan for your needs.

Many borrowers face a tough decision: lock in a fixed rate now or wait for potential RBA cuts. Let’s break it down.

Fixed home loan rates don’t always follow RBA cash rate changes immediately.
Lenders set rates based on:

Even if the RBA cuts rates, lenders may reduce fixed rates more slowly than expected.

Most experts forecast gradual rate reductions in late 2025 and into 2026.
Some lenders may offer temporary discounts or specials to attract new borrowers. However, the timing and size of cuts remain uncertain, meaning waiting can carry risk.

Economists also warn that external factors—like inflation trends, global markets, and RBA decisions—could influence rates in early 2026. Borrowers should prepare for slight fluctuations even if rates continue to trend lower.

A 1-year fixed rate is ideal if you’re unsure about future interest rates or planning to sell or refinance soon.
It often comes with the lowest short-term rates and gives you the flexibility to review your loan within a year.
However, it also carries higher risk if rates rise after your fixed period ends. You’ll need to refinance more frequently, which can mean extra effort and costs.

A 3-year fixed rate is the most popular choice among homeowners. It provides a good balance between stability and flexibility.
You’ll enjoy predictable repayments for three years and typically reasonable break costs if your plans change.
On the downside, the rate is slightly higher than a 1-year fix, and some lenders may limit extra repayments or redraws.

A 5-year fixed rate suits borrowers who want long-term certainty and peace of mind.
It protects you from interest rate spikes and guarantees stable repayments for half a decade.

However, it usually comes with higher fixed rates and less repayment flexibility. If you sell or refinance early, you could face significant break costs.

Pro Tip: A mortgage broker like Hunter Galloway can help tailor your fixed-rate strategy based on your loan amount, goals, and RBA outlook — ensuring you get the right balance between stability and savings.

When your fixed term ends, your loan typically reverts to the lender’s standard variable rate. This is called the revert rate.

Revert rates are usually higher than your fixed rate. Without action, your repayments can increase significantly, sometimes by hundreds of dollars per month.

You don’t have to accept the revert rate. You can negotiate or refinance before your fixed term expires. Taking action early helps you maintain control over repayments and potentially secure a lower interest rate.

Expert Tip: Contact your mortgage broker or lender three months before expiry. This gives time to compare rates and secure a deal without rushing.

Fixed home loans provide stability but come with trade-offs. Understanding the advantages and disadvantages will help you make smarter borrowing decisions.

Pro Tip: Always compare lenders’ fixed features and break costs. A mortgage broker like Hunter Galloway can guide you to the best solution.

Choosing a fixed home loan can provide stability, but many borrowers make avoidable mistakes. Understanding these pitfalls can save you thousands and make your loan work better for you.

“I fixed a few years ago worrying that interest rates would shoot up.

And they did, for a few months.

…And then they went down by a few per cent.

Consequently, my repayments were HUGE and breaking the fixed rate cost thousands of dollars.

Worse yet, I ended up putting the property on the market and selling it – during the fixed rate period.”

So if you aren’t 100% sure that you will be holding the property over the medium to longer term, then a fixed rate might not be for you.

Your mortgage broker can model repayment scenarios using loan calculators and RBA forecasts to help you find the ideal balance.

The good news is it is possible, depending on which bank you are with.

We have broken down the major banks, the name they used for their fixed rate home loan, fixed break cost and the maximum amount you can make in extra repayments.

Note: The actual amount you will pay in break costs depends heavily on a few factors (loan balance, how much time is left in the fixed-rate period, changes in wholesale interest rates). However, for Australian borrowers, break costs on large loans ($600k–$800k) can typically range between $10,000–$25,000, depending on rate differences and time left on the fixed term.

These policies are always changing.

We’d suggest calling your lender or speaking with our expert Mortgage Brokers to confirm the current policy on 1300 088 065.

When the loan started, Sarah’s fixed interest rate was 5.00%.
The current wholesale rate for the same remaining term is 3.50%.
That means the rate difference is 1.50% (0.015).

Multiply the rate difference by the remaining term of the loan:
0.015 × 2 years = 0.03 (or 3%).

Next, apply this percentage to the loan balance:
$650,000 × 0.03 = $19,500.

Banks apply a present value discount because the loss occurs over future years.
After discounting, the estimated break cost is approximately $18,700.

When Sarah fixed her rate at 5%, the bank locked in funds at that rate.
Now that wholesale market rates for the remaining two years have dropped to 3.5%, the bank earns 1.5% less if she exits early. The $18,700 break cost compensates the lender for this loss.

Essentially, the bank is recovering the income it expected to make had Sarah stayed on the fixed rate for the full term. If she breaks early, the lender must reinvest that money at a lower rate, resulting in a financial shortfall.
Break costs can also vary depending on how often repayments are made and how the lender calculates the discount rate. While the example gives a general idea, each bank uses slightly different formulas and discounting methods.

If market rates rise instead of fall, the situation can reverse — the bank may not charge any break cost, or in rare cases, the borrower might even benefit.

A split home loan lets you divide your mortgage into two portions — one fixed and one variable. This setup gives you the best of both worlds: the security of fixed repayments and the flexibility to take advantage of rate changes.

For instance, if you have a $400,000 loan, you might choose to fix $200,000 and keep $200,000 variable. You decide the ratio — whether it’s 70/30, 60/40, or 50/50 — depending on your financial goals and risk appetite.

You make one combined repayment, but it’s split across the two portions:

You can still make extra repayments, use offset accounts, or access redraw — but usually only on the variable side.

There’s no one-size-fits-all ratio — it depends on your risk tolerance and financial goals. Some common split setups include:

Choosing a fixed home loan can provide certainty and financial peace of mind, especially in a market where interest rates may fluctuate. Locking in a rate now ensures your repayments remain predictable for the fixed term, making budgeting easier if you have a tight or fixed household budget.

However, fixed loans are not one-size-fits-all. If you want both stability and flexibility, consider a split loan, which allows part of your loan to remain fixed while the other portion benefits from potential rate reductions. This approach helps you hedge against rate changes while still enjoying some predictability.

Always shop around and compare lenders, because even small differences in rates — for example, 6.49% vs 5.89% — can save you thousands of dollars over the life of the loan. Pay attention to features like extra repayments, offset accounts, and break fees, as these can significantly affect the true cost of your fixed loan.

In short, a fixed home loan can be a smart choice for borrowers seeking security, stability, and peace of mind — especially when paired with careful planning, professional advice, and a comparison of multiple lenders.
