How to Choose the Right Home Loan in Australia (2026)

Q: Is it better to go with a big bank or a smaller lender?

Smaller lenders and non-bank lenders often offer lower interest rates than the big four banks because they have lower overhead costs. Their loan products are typically just as secure (your deposit is still protected under the government guarantee for ADIs). The trade-off can be fewer branch locations and different (though often comparable) digital banking experiences. Many Australians save thousands over the life of their loan by choosing a competitive smaller lender.

Home Loan Types in Australia

Every home loan in Australia falls into one of three rate categories. Understanding these is the foundation for choosing the right loan.

Variable Rate Home Loans

A variable rate home loan has an interest rate that can change at any time. Your lender can increase or decrease the rate in response to changes in the official cash rate set by the Reserve Bank of Australia (RBA), or for other commercial reasons. When the rate changes, your repayment amount changes with it.

Variable loans are the most popular home loan type in Australia, and for good reason. They offer greater flexibility: you can typically make unlimited extra repayments, access a full offset account, and switch or refinance without paying break costs. The trade off is uncertainty. If rates rise significantly, your repayments increase, which can strain your budget.

Fixed Rate Home Loans

A fixed rate home loan locks in your interest rate for a set period, usually one to five years. During the fixed period, your repayments stay the same regardless of what happens to the RBA cash rate or the broader lending market.

Fixed rates appeal to borrowers who want certainty. If you are on a tight budget and need to know exactly what your repayment will be each month, fixing gives you that peace of mind. However, fixed loans come with restrictions: most limit extra repayments (typically to $10,000 to $20,000 per year during the fixed period), do not allow offset accounts (or offer a limited version), and charge break costs if you refinance or sell before the fixed period ends. Break costs can be substantial, sometimes tens of thousands of dollars.

Split Home Loans

A split loan divides your total borrowing into two portions: one fixed and one variable. For example, on a $600,000 loan, you might fix $300,000 for three years and leave $300,000 on a variable rate. This gives you partial certainty (the fixed portion) and partial flexibility (the variable portion, with offset and unlimited extra repayments).

Split loans are a practical middle ground for borrowers who want some rate protection but do not want to sacrifice the flexibility of a variable loan entirely. You can choose the ratio and the fixed term to suit your circumstances.

Repayment Structures: Principal and Interest vs Interest Only

Beyond the rate type, you need to choose your repayment structure.

Principal and Interest (P&I)

With principal and interest repayments, each payment reduces both the interest owing and a portion of the loan balance (the principal). Over the loan term, you gradually pay off the entire debt. P&I loans attract lower interest rates from almost every lender because the lender risk reduces as the loan balance decreases.

P&I is the standard repayment structure for owner occupiers and is mandatory for most owner occupied loans after an initial period. If you are buying a home to live in, you will almost certainly be on P&I repayments.

Interest Only (IO)

With interest only repayments, you pay only the interest on the loan for a set period (usually one to five years). The loan balance does not reduce during this time. Your repayments are lower during the IO period, but you are not building equity, and your repayments will increase when the IO period ends and you revert to P&I.

Interest only loans are primarily used by property investors for tax planning purposes (the interest is tax deductible on investment loans). Lenders charge a higher interest rate for IO loans, typically 0.30% to 0.60% above the equivalent P&I rate. Since APRA tightened lending standards, obtaining interest only terms for owner occupied loans has become significantly more difficult.

Key Point

Interest only loans do not save you money in the long run. They reduce your short term cash flow but result in higher total interest paid over the life of the loan because your principal balance is not reducing during the IO period. They make sense for investors with a specific tax strategy, but rarely for owner occupiers.

Key Home Loan Features to Compare

Beyond the rate, loan features can make a meaningful difference to the total cost and flexibility of your mortgage.

Offset Account

An offset account is a transaction account linked to your home loan. The balance in the offset account is deducted from your loan balance before interest is calculated. For example, if you owe $500,000 and have $50,000 in your offset account, you only pay interest on $450,000. This can save significant interest over the life of the loan without you losing access to your money.

A 100% offset account is one of the most powerful home loan features available. It is especially valuable if you maintain healthy cash reserves, receive your salary into it, or use it as part of a salary parking strategy. Read our complete offset account guide for a detailed breakdown.

Redraw Facility

A redraw facility allows you to access any extra repayments you have made on your loan above the minimum required. For example, if you have paid $20,000 extra over the past two years, you can redraw some or all of that $20,000 if you need it. Most variable rate loans include a free redraw facility.

The key difference between offset and redraw is ownership and access. Money in an offset account is yours and instantly accessible. Extra repayments available for redraw have technically been applied to your loan and some lenders may restrict access or charge fees for redraw. For most people, an offset account is the more flexible option.

Extra Repayment Flexibility

The ability to make additional repayments above the minimum without penalty is essential. On a $500,000 loan at 6.00%, an extra $200 per month saves approximately $65,000 in interest and takes 4 years off a 30 year loan. Variable loans almost always allow unlimited extra repayments. Fixed loans typically cap them at $10,000 to $20,000 per year.

Portability

Loan portability allows you to transfer your existing loan to a new property if you sell and buy. This can save you the costs of discharging one loan and establishing a new one, including application fees, valuation fees, and potential break costs on fixed loans.

Fee Structure

Common home loan fees include: application or establishment fees ($0 to $600), annual or ongoing fees ($0 to $395 per year), discharge or settlement fees ($150 to $400 when you close the loan), and valuation fees ($0 to $300). A loan with a slightly higher rate but no ongoing fees may work out cheaper than a lower rate loan with a $395 annual package fee, depending on your loan size and how long you hold the loan.

Types of Lenders in Australia

Australia has a diverse lending market. Understanding the different types of lenders helps you compare effectively.

Big Four Banks

Commonwealth Bank, Westpac, ANZ, and NAB together hold the majority of the Australian mortgage market. They offer extensive branch networks, established digital platforms, and a wide range of products. However, their rates are typically not the most competitive, and their size can mean slower processing times and less personalised service.

Smaller Banks and Mutual Institutions

Banks like Macquarie, ING, Bank of Queensland, Suncorp, and mutual institutions (credit unions and building societies) often offer more competitive rates than the big four. They are Authorised Deposit Taking Institutions (ADIs) regulated by APRA, and deposits up to $250,000 are protected under the government guarantee, just as they are with the big four.

Non Bank Lenders

Non bank lenders like Pepper Money, Liberty, Resimac, and La Trobe Financial do not hold a banking licence and cannot accept deposits. They fund their loans through the wholesale securitisation market. Non bank lenders often serve borrowers who do not meet traditional bank criteria (self employed, non standard income, adverse credit history) and may offer competitive rates in certain segments.

Tip

Do not assume the big four banks offer the best products or the most security. Smaller ADI lenders are subject to the same APRA regulation and government deposit guarantee. The primary reason to choose a big four bank is convenience (branch access and integrated banking), not safety.

Comparison Rates: What They Tell You and What They Do Not

Australian law requires lenders to display a comparison rate alongside their advertised interest rate. The comparison rate includes the interest rate plus most ongoing fees and charges, expressed as a single percentage.

The comparison rate gives you a more accurate picture of the true cost of a loan than the headline rate alone. A loan advertising 5.99% with a $395 annual fee and $600 establishment fee may have a comparison rate of 6.15%, which is a fairer number to compare against a loan advertising 6.09% with no fees (comparison rate 6.10%).

However, comparison rates have a significant limitation: they are all calculated on a standardised $150,000 loan over 25 years. If your loan is $600,000 over 30 years, the impact of fees relative to interest is very different. On larger loans, the annual fee matters less relative to the rate, so a lower rate with a higher fee can actually be cheaper. On smaller loans, fees have a proportionally larger impact. Always calculate the total cost for your specific loan amount and term rather than relying solely on the comparison rate.

Owner Occupier vs Investor Loans

Lenders price owner occupier and investment home loans differently. Investment loans typically carry an interest rate premium of 0.20% to 0.50% above the equivalent owner occupier rate. This pricing difference exists because regulators (APRA) view investment lending as carrying higher systemic risk, and lenders must hold more capital against investment loans.

If you are purchasing a property to live in, ensure your loan is classified as owner occupied, as this will give you access to the lowest rates. If you move out and rent the property, most lenders require you to notify them and reclassify the loan as investment, which may trigger a rate increase.

Loan to Value Ratio (LVR) and Its Impact on Your Rate

Your Loan to Value Ratio (LVR) is the amount you are borrowing expressed as a percentage of the property value. If you are borrowing $450,000 to buy a $600,000 property, your LVR is 75%.

LVR has a direct impact on both your interest rate and your eligibility for different loan products. Most lenders offer their best rates at LVRs of 60% or below, with slightly higher rates at 60% to 80%, and a noticeable premium for LVRs above 80%. At LVRs above 80%, you will also need to pay Lenders Mortgage Insurance (LMI) unless you are eligible for a government guarantee scheme or have a guarantor. Read our LMI guide for more detail.

Why Use a Mortgage Broker?

A mortgage broker is a licensed credit professional who compares home loans from multiple lenders on your behalf. In Australia, brokers now originate the majority of all home loans, a figure that has grown steadily over the past decade.

Brokers are paid by the lender on settlement (not by you), so their service is free to the borrower. A broker typically has access to 30 to 60 or more lenders, including banks, credit unions, and non bank lenders. They assess your circumstances, recommend suitable products, handle the application paperwork, and manage the process through to settlement.

The primary advantage of using a broker is breadth of comparison. Going directly to a bank means you see only that bank products. A broker shows you options across the entire market, including lenders you may not have heard of that offer better rates or more suitable features for your situation.

Key Point

Under the Best Interests Duty introduced in January 2021, Australian mortgage brokers are legally required to act in your best interests when recommending a loan. This is a stronger consumer protection than exists for bank lending staff, who are not subject to the same obligation.

Common Home Loan Mistakes to Avoid

Choosing on rate alone. The lowest rate is not always the cheapest loan. A loan at 5.89% with a $395 annual fee and limited features may cost more over time than a 5.99% loan with a free offset account that saves you $300+ per month in interest.
Ignoring the comparison rate. The headline rate attracts your attention, but the comparison rate tells you the true cost including fees. Always compare like with like.
Not reviewing your loan regularly. The Australian mortgage market is highly competitive and rates change constantly. If you have not reviewed your home loan in the past 12 months, there is a strong chance you are paying more than you need to. Many borrowers save 0.30% to 0.80% simply by refinancing to a more competitive lender.
Paying for features you do not use. A fully featured package loan with offset, redraw, and portability costs more (via higher rates or annual fees) than a basic loan. If you are not going to use the offset account or make extra repayments, a basic no frills loan with a lower rate may be the smarter choice.
Fixing your entire loan. Fixing your entire balance removes the ability to make meaningful extra repayments and use an offset account. Unless you have a strong reason for total certainty, consider fixing only a portion (a split loan) to retain some flexibility.
Not factoring in future rate rises. When comparing loans, stress test your repayments at 2% to 3% above the current rate. If your budget cannot handle a rate increase, you may be borrowing too much or choosing the wrong loan structure.

Your Home Loan Decision Checklist

Use this checklist when evaluating home loan options to ensure you are comparing everything that matters.

What is the interest rate and comparison rate? Compare both for an accurate picture of total cost.
Is the rate variable, fixed, or can I split? Choose based on your need for certainty versus flexibility.
Does it include a 100% offset account? If you maintain cash reserves, this feature can save you thousands.
Can I make unlimited extra repayments? Essential if you want to pay off your loan faster.
What are the ongoing fees? Annual fees, monthly fees, and any transaction charges add up over 30 years.
What are the exit costs? Discharge fees, break costs (for fixed loans), and any clawback clauses.
What LVR tier am I in, and am I getting the best rate for that tier? Small differences in LVR can put you in a cheaper rate band.
Is the lender service reliable? Check reviews for processing times, communication quality, and digital banking experience.
Have I compared across different lender types? Big four, smaller banks, and non bank lenders all have different strengths.
Have I stress tested my repayments? Ensure you can afford repayments if rates rise 2% to 3%.

Frequently Asked Questions

There is no single best home loan type. The right choice depends on your financial goals, risk tolerance, and circumstances. Variable rate loans offer flexibility and offset account access. Fixed rate loans offer repayment certainty. Split loans offer a combination of both. Most owner occupiers in Australia choose variable or split loans because of the flexibility and offset account benefits.

The most valuable features for most borrowers are: an offset account (reduces interest without losing access to your savings), redraw facility (access extra repayments if needed), the ability to make extra repayments without penalty, and reasonable discharge and switching fees. Avoid paying for features you will not use, as fully featured loans typically carry higher interest rates.

You should compare at least 5 to 10 lenders across different categories (big four banks, smaller banks, credit unions, and non bank lenders) to get a fair picture of what is available. A mortgage broker can compare 30 to 60 or more lenders on your behalf, which saves time and ensures you are not missing better options outside the lenders you already know.

Smaller lenders and non bank lenders often offer lower interest rates than the big four banks because they have lower overhead costs. Their loan products are typically just as secure (your deposit is still protected under the government guarantee for ADIs). The trade off can be fewer branch locations and different (though often comparable) digital banking experiences. Many Australians save thousands over the life of their loan by choosing a competitive smaller lender.

The advertised rate (or headline rate) is the interest rate applied to your loan balance. The comparison rate includes the interest rate plus most fees and charges associated with the loan, expressed as a single percentage. It gives a more accurate picture of the true cost. However, comparison rates are calculated on a $150,000 loan over 25 years, so they may not perfectly reflect the cost for your specific loan amount and term.

The decision to fix depends on your personal circumstances rather than trying to predict rate movements. Consider fixing if you need budget certainty (for example, you are planning parental leave or reducing work hours), if current fixed rates are materially below variable rates, or if you want to protect against potential rate increases. Consider staying variable if you want maximum flexibility, plan to make extra repayments, or want full offset account functionality. A split loan can offer the best of both approaches.
