How Much Does a Mortgage Broker Cost in Australia?
One of the most common questions from home buyers is whether using a mortgage broker will cost them anything. The short answer for most borrowers is no: mortgage brokers in Australia are free to use. But it is worth understanding exactly how the system works so you can make an informed decision.
The Short Answer: Usually Nothing
In Australia, mortgage brokers are paid by the lender, not by you. When your home loan settles, the lender pays the broker a commission for bringing them your business. This means you get expert advice, market comparison, and application support at no direct cost.
This is not a hidden cost added to your loan. The commission structure is the same whether you go through a broker or walk into the bank directly. You do not pay a higher interest rate for using a broker.
How Broker Commissions Work
Brokers receive two types of payments from lenders:
Upfront Commission
This is paid when your loan settles. It is typically 0.5 per cent to 0.7 per cent of the loan amount (including GST). On a $500,000 loan, the broker receives roughly $2,500 to $3,500.
Trail Commission
This is an ongoing payment of around 0.15 per cent to 0.2 per cent per year of the outstanding loan balance. It is paid monthly for as long as the loan remains active. On a $500,000 loan, this starts at about $62 to $83 per month and decreases as the loan balance reduces.
Clawback Provisions
If you refinance or discharge your loan within the first 1 to 2 years, the lender may claw back some or all of the upfront commission from the broker. This is why some brokers may be reluctant to recommend very short-term loan strategies.
Do Any Brokers Charge Fees?
A small number of brokers do charge fees, typically in these situations:
- Complex commercial loans: Some brokers charge fees for commercial or development finance where the work involved is significantly greater
- Fee-for-service model: A small number of brokers rebate their commission and charge a flat fee instead, arguing this removes any potential conflict of interest
- Non-standard applications: Very occasionally, brokers may charge a fee for complex situations that require extensive work but may not result in a commission
If a broker wants to charge you a fee for a standard residential home loan, you should ask why and consider whether other brokers can provide the same service for free.
Hidden Costs to Watch For
While the broker's service is free, the home loan process itself involves costs that you should budget for:
- Loan establishment fees: Some lenders charge $200 to $600 to set up your loan (many brokers can negotiate these away)
- Valuation fees: The lender may charge $300 to $600 for a property valuation
- Lenders Mortgage Insurance: If your deposit is less than 20 per cent, LMI can cost thousands of dollars
- Legal and conveyancing fees: Typically $1,000 to $2,500 for property transfer and settlement
- Stamp duty: The biggest cost, varying by state and property value
A good broker will explain all of these costs upfront so there are no surprises.
Is Free Really Free?
Some people worry that if a broker is being paid by lenders, there must be a catch. The Best Interests Duty, introduced in 2021, specifically addresses this concern. Brokers are now legally required to prioritise your interests above their own. They must recommend the loan that best suits your needs, regardless of which lender pays the highest commission.
Commission rates across major lenders are also fairly standardised, which further reduces any potential conflict. The difference in commission between lenders is usually minimal compared to the difference in rates and features.
The Bottom Line
Using a mortgage broker costs most Australian borrowers nothing. You get free access to expert advice, market-wide comparison, and professional application management. The broker is paid by the lender, and you are protected by law through the Best Interests Duty.
The real cost of not using a broker is the potential to overpay on your home loan because you did not compare the full market.
