How Do Mortgage Brokers Get Paid?

Brokers receive two types of commission from the lender: an upfront commission when your loan settles and an ongoing trail commission for the life of the loan. Neither of these commissions is paid by you. They are built into the lender's cost structure and apply whether you use a broker or go directly to the bank. Here is how the numbers typically work.

Commission TypeTypical RateExample on $600,000 Loan
Upfront commission0.5% - 0.7% of loan amount$3,000 - $4,200
Trail commission0.15% - 0.2% per year$900 - $1,200 per year

The upfront commission is paid by the lender to the broker (or their aggregator) once your loan settles. The trail commission is paid monthly for as long as the loan remains active. If you refinance or pay off the loan, the trail commission stops. Some lenders pay higher upfront and lower trail, or vice versa, but the total package is broadly similar across the industry.

The trail commission creates an incentive for your broker to maintain an ongoing relationship with you. A good broker will proactively review your loan annually and contact you if better options become available, because keeping you as a client means they continue to earn trail. This ongoing service is one of the key advantages of using a broker over going direct.

Does Using a Broker Cost Me More?

No. You pay the same interest rate whether you apply through a broker or go directly to the lender. This is one of the most common concerns borrowers have, and the answer is straightforward. Lenders do not increase the interest rate to cover broker commissions. The rate you receive is the same rate offered to customers who walk into a branch. In some cases, brokers can actually negotiate a lower rate than you would get going direct, because they have volume-based leverage with lenders.

Since January 2021, mortgage brokers in Australia are legally required to act in your best interests under the Best Interests Duty (BID) regulations enforced by ASIC. This means your broker must recommend the loan that is most appropriate for your needs, not the one that pays them the highest commission. This legal obligation provides a strong consumer protection that does not exist when you deal directly with a bank, where the staff member's obligation is to sell you their employer's products.

Best Interests Duty Explained

Since 2021, Australian mortgage brokers are legally required to act in your best interests, not the lender's and not their own. The Best Interests Duty (BID) was introduced by the federal government following the Royal Commission into Misconduct in the Banking, Superannuation and Financial Services Industry. It fundamentally changed the obligations brokers have to their clients.

In practical terms, this means your broker must consider your financial situation, objectives and needs, and recommend a loan that is appropriate for you. They cannot recommend a product solely because it pays a higher commission. They must document why the recommended product is in your best interests, and this documentation can be requested by ASIC during audits.

If a broker breaches the Best Interests Duty, they face significant penalties including fines and loss of their credit licence. This regulatory framework gives borrowers a level of legal protection when using a broker that does not exist when dealing directly with a bank. A bank employee is under no obligation to tell you about a competitor's better product.

Broker vs Going Direct to a Bank

A broker compares products from dozens of lenders on your behalf, while a bank can only offer you their own products. This is the fundamental difference, and it has practical implications across several areas.

FactorMortgage BrokerDirect to Bank
Lenders compared30 - 60+ lenders1 lender (their own products)
Cost to borrowerFreeFree
Product rangeHundreds of productsLimited to own range
Best interests dutyLegally requiredNo obligation to act in your best interests
Rate negotiationCan leverage competition between lendersLimited to internal discretion
Ongoing supportAnnual reviews, proactive refinance checksGenerally reactive only

Going direct to a bank can make sense if you have a longstanding relationship with a particular lender, if you have complex banking needs that are best served by a single institution, or if you have already done extensive research and know exactly which product you want. For most borrowers, however, the comparison and negotiation a broker provides delivers a measurably better outcome.

When Should You Use a Broker?

A broker adds the most value when you need expert guidance navigating complex lending criteria, multiple lenders, or non-standard situations. While a broker is useful for almost any home loan, there are specific scenarios where the value they provide is particularly significant.

1. First Home Buyers

If you have never purchased a property before, a broker guides you through the entire process, from understanding how much you can borrow to coordinating with your conveyancer and real estate agent. They also ensure you access all available government schemes and grants.

2. Self-Employed Borrowers

Self-employed applicants face more complex income verification requirements. Different lenders have different policies on how many years of financials they require, whether they accept add-backs, and how they assess variable income. A broker knows which lenders are most favourable for self-employed applicants.

3. Refinancing

When refinancing, a broker can compare your current rate against the market, calculate whether the cost of switching is justified by the savings, and manage the application process with the new lender. They can also negotiate with your current lender on your behalf to get a better rate without refinancing.

4. Complex Financial Situations

If you have multiple income sources, a history of credit issues, existing debts, or are buying an unusual property type (hobby farm, commercial-residential mix, or high-density apartment), a broker's knowledge of lender policies across their panel is invaluable. Some lenders that decline an application may be accepted by others with different assessment criteria.

5. Time-Poor Buyers

Comparing home loans across dozens of lenders takes significant time. A broker does this research for you, presents the best options, handles the paperwork, and follows up with the lender throughout the approval process. For buyers who are busy with work and family, this convenience alone is worth using a broker.

How to Choose a Good Broker

The best brokers have a large lender panel, strong communication skills, relevant experience and a track record of client satisfaction. Not all brokers are equal. Here are four things to look for.

1. Panel Size and Lender Diversity

A broker with access to 30 or more lenders can genuinely compare the market. If a broker only has six to eight lenders on their panel, your options are limited. Ask how many lenders they work with and whether their panel includes major banks, non-bank lenders and credit unions.

2. Communication and Responsiveness

Your broker should return calls and messages within a few hours, provide clear timelines for each stage of the process, and keep you informed without being asked. During the application process, delays can cost you a property. Responsiveness matters.

3. Relevant Experience

If you are self-employed, look for a broker who regularly works with self-employed clients. If you are buying an investment property, find a broker with investment lending experience. Ask about their typical client profile and whether they have handled situations similar to yours.

4. Reviews and Referrals

Check Google reviews, ask friends or family for referrals, and look for brokers who have won industry awards or hold memberships with the MFAA (Mortgage and Finance Association of Australia) or FBAA (Finance Brokers Association of Australasia). A strong online reputation built over several years is a reliable indicator of consistent service quality.

Common Myths About Mortgage Brokers

Several persistent myths about mortgage brokers prevent borrowers from accessing free professional advice that could save them thousands.

Myth 1: Brokers Only Recommend Loans That Pay the Highest Commission

This may have been a concern before 2021, but the Best Interests Duty now legally requires brokers to recommend the product that is most appropriate for your needs. ASIC actively audits broker files to ensure compliance. Commission rates between lenders are broadly similar, so there is limited incentive to favour one product over another for commission reasons.

Myth 2: Banks Offer Better Rates Than Brokers

The rate you receive through a broker is the same as (or better than) what you would get going direct. Brokers can often negotiate better rates because they represent multiple potential customers and lenders compete for their business. If a bank offers you a rate directly, a good broker can usually match or beat it.

Myth 3: Brokers Slow Down the Application Process

In most cases, the opposite is true. Experienced brokers know each lender's documentation requirements and submission processes. They submit clean, complete applications that avoid the back-and-forth that often delays direct applications. A broker who regularly works with a particular lender understands their turnaround times and can set realistic expectations.

Myth 4: You Only Need a Broker for Your First Loan

A broker adds value at every stage of your property journey. Refinancing, purchasing investment properties, accessing equity, restructuring debt, and negotiating better rates on existing loans are all areas where a broker's expertise and market access deliver measurable financial benefits. The ongoing trail commission means your broker has a financial incentive to keep you as a client for life.

Frequently Asked Questions

No. Mortgage brokers in Australia are paid entirely by the lender through upfront and trail commissions. You do not pay any fee, charge or hidden cost for using a broker. The interest rate you receive is the same as going directly to the lender.
Brokers typically earn an upfront commission of 0.5% to 0.7% of the loan amount at settlement, plus an ongoing trail commission of 0.15% to 0.2% per year. On a $600,000 loan, this means approximately $3,000 to $4,200 upfront and $900 to $1,200 per year in trail. These figures are paid by the lender.
No. Lenders offer the same interest rate whether you apply through a broker or directly. In some cases, brokers can negotiate a lower rate than you would receive going direct because they leverage the competition between lenders on their panel.
No. Each broker works with a panel of lenders determined by their aggregator. Most large aggregators have panels of 30 to 60 or more lenders, including major banks, non-bank lenders and credit unions. A few lenders (such as some direct-only neobanks) do not work with brokers at all. Ask your broker about their panel before proceeding.
The Best Interests Duty is a legal obligation introduced in 2021 that requires mortgage brokers to recommend the loan that is most appropriate for your needs, not the one that pays them the highest commission. It is enforced by ASIC and carries significant penalties for non-compliance. This obligation does not apply to bank staff, who are only required to sell their employer's products.
Using multiple brokers is generally unnecessary if you choose a broker with a large lender panel. A broker with 40 or more lenders can already compare the majority of the market. Using multiple brokers can also lead to duplicate credit enquiries that may affect your credit score. If you are unsure about your broker's recommendations, ask them to explain why they have recommended a particular product and what alternatives they considered.
