Coming Off a Fixed Rate in Australia? Here's What Actually Happens Next (and How to Avoid the $9,500 Mistake)

Hundreds of thousands of Australian homeowners are coming off their fixed rates this year. If you're one of them, what happens in the weeks before that fixed term ends could be the most expensive financial decision you make this decade.

The pattern we see again and again: borrowers don't act, the bank rolls them silently onto a revert rate, and repayments jump $600–$1,000 a month overnight. No call. No warning. Just a higher direct debit, sometimes 30 days later.

This article covers what actually happens when your fixed rate ends in Australia, what your real options are, and how to time the refinance properly. It costs nothing to find out where you stand.

What is the "fixed rate cliff"?

Between 2020 and 2022, hundreds of billions of dollars of Australian home loans were fixed at rates between 1.99% and 2.49% — historic lows driven by RBA pandemic policy. Those fixed terms are now expiring in waves.

The "fixed rate cliff" is the term used to describe what happens when borrowers come off those ultra-low rates onto today's standard variable rates of 6.5%–7.2%. The jump is brutal.

What happens when my fixed rate expires in Australia?

This is the question most borrowers don't ask until it's already happened. The honest answer: your bank does the minimum legally required, which is almost nothing.

Here's the typical sequence:

1. 30–60 days before expiry: Your lender may send a generic letter or email. It usually mentions your fixed term ends, lists a couple of options, and includes the standard variable rate (which is almost always their worst rate).
2. The day your fixed term expires: The loan automatically rolls onto the revert rate — typically the standard variable rate, not their best variable rate. No phone call. No advice. No comparison.
3. First repayment after expiry: Your direct debit jumps. Often by hundreds of dollars per month.
4. Weeks later: You notice. By then you're already paying the higher rate, sometimes for several billing cycles before you act.

The four real options when your fixed rate expires

You have more choice than the bank lets on. Every borrower in Australia who's coming off a fixed rate has these four options:

The right option depends on your numbers, your goals, and how much equity you have. But you can't make a sensible decision without seeing what's actually available across the market.

When should I act?

Earlier than you think. The best time to start the refinancing conversation is 3–4 months before your fixed rate expires. Here's why:

• Refinances take 4–8 weeks to settle from application to lender funding. Starting the day your rate expires means you'll have already paid weeks or months at the higher revert rate.
• Lenders shift their rates frequently. Locking in a competitive rate early protects you from market movement.
• Valuations and approvals take time. Some lenders are slow. Building in a buffer means you're not stuck on a revert rate while paperwork crawls through.
• Negotiation works better when you have a real alternative. If your bank knows you're already approved with a competitor, they'll fight harder to keep you.

What does a competitive refinance actually look like?

Real numbers, on a $650,000 owner-occupied loan over 30 years:

• Revert rate (the default trap): 6.90%, repayments of $4,281 per month
• Best available rate via a broker: 5.80%, repayments of $3,814 per month
• Difference: $467 per month, or $5,604 per year, back in your pocket
• Over the life of the loan: approximately $168,000 in saved interest

And to be clear — that's not theoretical. That's the gap between what your bank quietly puts you on if you do nothing, and what a broker can secure for you by comparing 30+ lenders. The loan is the same. The property is the same. Just a different lender.

The five-step refinancing process when coming off a fixed rate

If you've never refinanced before, here's what actually happens:

1. 15-minute review (week 1): A broker reviews your current loan, income, and goals. They tell you whether refinancing makes sense and roughly what you could save.
2. Comparison and selection (week 1–2): The broker compares lenders on your specific situation — rate, fees, features, serviceability — and recommends the best fit.
3. Application and supporting documents (week 2–3): Payslips, ID, bank statements, current loan statement. The broker prepares and submits everything.
4. Valuation and approval (week 3–5): The new lender orders a property valuation and assesses the application. Most refinances are approved within this window.
5. Settlement (week 5–8): The new lender pays out the old one, the loan transfers, and your new lower repayments begin. You don't move house. You don't change anything physical. Just a better rate, a better lender, more money in your pocket each month.

Your existing bank doesn't get a say. You're not asking permission. Refinancing in Australia is a competitive market and lenders compete for your business — that's the whole point.

Common questions about fixed rate expiry in Australia

Will my bank automatically offer me their best rate when my fixed term ends?

No. Your bank will roll you onto the revert rate — typically the standard variable rate, which is rarely competitive. To get their best available rate, you usually have to call, ask, and negotiate. Even then, you're only seeing one bank's products.

How much can I actually save by refinancing off a fixed rate?

On a typical $650,000 loan, the difference between the bank's revert rate and a market-competitive rate is around $400–$700 per month, or $5,000–$9,000 per year. Over the life of a 30-year loan that's tens to hundreds of thousands of dollars in interest.

Do I have to leave my current bank to get a better rate?

Not always. Sometimes your current bank will match a competitive offer if you ask hard enough. But you need a real, approved alternative to negotiate with. That's where a broker helps — they'll either move you to a better lender, or use a competing approval as leverage to negotiate down your existing bank's rate.

Will refinancing cost me anything?

The broker's service costs you nothing — lenders pay our commission. The refinance itself may have small fees (discharge fee from your old bank, settlement fee for the new one, government registration costs), typically totalling $400–$700. On a $9,000 annual saving, these are recouped in the first month.

How long does it take to refinance off a fixed rate?

Typically 4–8 weeks from start to settlement, depending on the lender and how quickly documents come together. This is why starting 3–4 months before your fixed term expires is ideal.

What if I refinance and rates drop again?

You can refinance again. There's no penalty after you're on a variable rate (or once a new fixed term ends). A good broker reviews your loan annually and tells you when it's worth switching again.

The honest summary

The fixed rate cliff is real, but it's not the cliff itself that costs people money — it's the silence after they roll off. The bank's revert rate is the path of least resistance, and it's almost always the worst financial outcome.

15 minutes of conversation with a broker, 3–4 months before your fixed rate expires, is one of the highest-return things you can do for your household finances. Lenders pay our fees. You don't.
