Introduction
Your mortgage repayments have gone up three times this year. The RBA meeting held in Sep did not rule out another hike. Your fixed rate term is ending soon, or you are about to sign your first home loan, and nobody is giving you a straight answer.
Fixed or variable is not a rate question. It is a question about what happens to your household if repayments climb another $200 a month, whether you can afford to be locked in if you need to sell, and whether keeping cash in an offset account is worth more to your position over the long term than locking in certainty today.
This guide gives you the honest breakdown. It covers first home buyers in North Brisbane, existing homeowners reassessing their loan, investors structuring a growing portfolio, and anyone who has been told by their bank that now is a good time to fix without being told why.
What the RBA Decision Means for Your Home Loan Right Now
The RBA raised the cash rate by 25 basis points to 4.60% on 29 September 2026 — its fourth increase of 2026, following hikes in February, March, May, and now September. Inflation is still running hot. Upside risks including rising global energy prices are materialising, and the Board has kept further tightening firmly on the table.
Cut coming? Not yet. The Board signalled nothing of the sort.
For Brisbane borrowers, this is not settled ground. Trimmed mean inflation is holding at 3.6%, and while the headline CPI figure for June came in at 3.8% — slightly lower — both numbers still sit above the 2 to 3% target band the RBA needs to hit before it considers easing. The numbers are moving in the right direction. Just not fast enough.
That is the environment in which you are choosing between fixed and variable. Do not defer it to after you sign.
Fixed and Variable: What You Actually Get and Give Up
A fixed rate loan locks your interest rate for a set term — typically one, two, three, or five years. Repayments stay the same regardless of what the RBA does during that period. When the term ends, the loan rolls onto the lender’s standard variable rate unless you refix or refinance.
Variables are different. Your rate tracks the lender’s standard variable rate, which moves with RBA cash rate decisions. Repayments go up when rates rise. They come down when rates fall. Most variable loans also include an offset account and allow unlimited extra repayments — two features fixed loans almost never offer.
So the question is not which rate looks lower today. It is what you are giving up to get that certainty — and whether that trade makes sense for where rates are likely to go.
The Side-by-Side You Need Before You Decide
| Feature | Fixed Loan | Variable Loan |
| Repayment certainty | Locked for fixed term | Changes with rate moves |
| Rate rise protection | Yes, during fixed term | No |
| Rate cut benefit | No, you stay locked | Yes, repayments fall |
| Offset account access | Rarely available | Standard on most loans |
| Extra repayments | Capped (often $10k to $30k per year) | Unlimited on most loans |
| Break fee on early exit | Yes, can be significant | None |
| Refinance or sell freely | Restricted during fixed term | Anytime |
The Offset vs Redraw Question Nobody Tells You About
Most borrowers compare fixed and variable rates and stop there. The feature that often matters more is whether you get an offset account and what you lose if you do not.
Both an offset account and a redraw facility reduce the interest you pay. An offset account is a separate transaction account linked to your loan. Its balance reduces the amount your interest is calculated on every day. A redraw facility holds extra repayments inside the loan. You can pull them back when needed.
At a cash rate of 4.35%, a $60,000 balance in either feature saves roughly $3,540 per year at a 5.9% variable rate. Mathematically identical. But the tax treatment is where things get complicated, especially if you’re an investor.
Pull money out of a redraw for something private, a holiday, a reno on your own home, clearing a personal debt, and the ATO reclassifies that withdrawal as a new private borrowing. The interest on that chunk is no longer deductible. This happens even if the original loan was 100% for investment purposes. Tax professionals call it a contaminated loan, and once it’s contaminated, unwinding it is painful and expensive.
An offset account sidesteps this entirely. Your money sits in a separate transaction account, never mixed with the loan principal. The ATO sees them as two different things, because they are.
So the saving looks the same on paper. The risk profile isn’t.
The practical result: offset accounts come almost exclusively with variable loans. If an offset account matters to your strategy, and for investors and buyers focused on cash flow it almost always does, that alone is often the deciding factor.
Which loan structure fits your situation
First home buyers in North Brisbane (Strathpine, North Lakes, Chermside, Aspley)
Median house prices between $900,000 and $1.1 million. First home buyer budget. That’s a stretch by any measure.
When you’re already pushing your borrowing limit, the last thing you need is your repayments moving around on you. A fixed rate for 2 to 3 years locks in a number you can actually plan around while you find your feet as a homeowner. Rates go up? Doesn’t affect you. Unexpected costs in year one? At least your mortgage isn’t adding to the stress.
It’s not the most flexible structure. But flexibility matters less when predictability is what keeps you in the property.
A split loan works well here too. Fix the majority for certainty and keep a variable portion for offset access and flexibility.
Existing homeowners whose fixed rate is expiring
If you fixed in 2022 or 2023 and your term is ending, your loan is about to roll onto the lender’s revert rate. That is typically their highest standard variable rate, not their competitive pricing. Do not let it happen automatically. Start reviewing your options 60 to 90 days before the term ends. This is one of the most common situations where refinancing to a new lender saves Brisbane homeowners thousands.
Property investors building a portfolio
Variable or interest-only variable structures dominate investor loan strategies for the reasons set out above. The offset account advantage over redraw is decisive from a tax perspective. Variable also gives you the freedom to refinance, sell, or restructure without break costs as your portfolio grows.
Self-employed professionals including doctors, nurses, lawyers, dentists, and accountants
Income that varies year to year makes variable flexibility valuable. Keeping cash accessible in an offset rather than locked inside a fixed loan with capped extra repayments suits income patterns that fluctuate. Brisbane Home Loans has dedicated experience with home loans for doctors, nurses, lawyers, dentists, and accountants, including low doc and alt doc structures where standard income documentation does not apply.
Buyers comparing going direct to a bank versus using a broker
Going direct to a bank gives you that institution’s product range and their pricing. A mortgage broker in Brisbane compares fixed, variable, and split structures across a full lender panel, including non bank lenders who regularly price sharper than the big four on both fixed and variable products. You pay no broker fees. The lender pays the broker after your loan settles.
Why Most Brisbane Buyers End Up Choosing a Split Loan
A split loan divides your mortgage into a fixed portion and a variable portion. Fix 60% and keep 40% variable, for example. The fixed portion locks in your repayment on that share of the loan regardless of rate moves. The variable portion gives you offset account access, unlimited extra repayments, and the ability to benefit from future rate cuts.
Split loans take the pressure off picking a side completely. They suit borrowers who want some certainty and some flexibility, which describes most people weighing this decision honestly. The ratio you choose should reflect how much of each you actually need, not a standard formula.
The Break Cost Trap That Catches Brisbane Borrowers Off Guard
The most expensive mistake borrowers make is fixing the entire loan and then needing to exit it. This happens when they sell the property, decide to refinance, or come into money and want to pay the loan down faster.
Break costs on a fixed loan are not a flat fee. Lenders calculate them based on the gap between your locked rate and current market rates for the remaining term. If rates have fallen since you fixed, that gap can produce a break cost running into tens of thousands of dollars on a large Brisbane loan.
If there is any realistic chance you will sell, refinance, or make significant lump sum repayments within the fixed term, do not commit the entire loan to a fixed structure. Keep at least part variable. The break cost risk alone justifies it.
How a Brisbane mortgage broker makes this decision clearer
Fixed, variable, or split comes down to your life over the next 2 to 3 years. How stable is your income? Are you likely to move? How much are you willing to pay for certainty?
Brisbane Home Loans compares structures across a full lender panel, including non-bank lenders you won’t see when you walk into a big four branch. We run the real dollar difference between your options, factor in your offset strategy, and land on a structure that fits your cash flow and your plans.
But here’s the honest part: most people who come to us think they’ve already decided. They usually haven’t. Once we show them the numbers side by side, the answer gets a lot clearer.
The conversation is free. Getting the structure wrong costs real money.
