What a mortgage broker does and how they get paid in Australia
Property buyers across Sydney, Melbourne, and Brisbane routinely turn to mortgage brokers when navigating the country's home loan market. With hundreds of loan products available from more than 60 lenders, comparing options without specialist help can feel overwhelming. A mortgage broker acts as an intermediary between borrowers and lenders, researching products, preparing applications, and managing much of the paperwork that comes with securing finance for a home purchase or refinance.
Understanding how these professionals are paid is just as important as understanding what they do. Commission structures, regulatory obligations, and the way brokers are reimbursed can directly influence the advice borrowers receive. The following sections explain the role, the compensation model, and the consumer protections that shape the industry in Australia.
The role of a mortgage broker in Australia
A mortgage broker is a licensed credit representative who assesses a borrower's financial situation, recommends suitable home loans, and submits the application on their behalf. Brokers in Australia must hold an Australian Credit Licence or be authorised as a credit representative under the National Consumer Credit Protection Act 2009. They work with a panel of lenders that typically includes the big four banks, regional banks, credit unions, building societies, and non-bank lenders.
Most brokers offer an initial consultation at no cost, during which they collect details about income, expenses, existing debts, and savings. They then compare interest rates, features, and fees across their panel, often using software that calculates a comparison rate, the true cost of a loan including most fees and charges. Once a borrower chooses a product, the broker lodges the application and follows it through to settlement, acting as a single point of contact between the borrower, the lender, and sometimes the solicitor or conveyancer.
How brokers are compensated
In most cases, mortgage brokers are paid by the lender, not the borrower. When a loan settles, the lender pays the broker a commission, which is built into the loan amount rather than billed separately. This means borrowers typically do not pay out-of-pocket for the broker's services, although some brokers charge an explicit fee that is disclosed upfront and agreed in writing before any work begins.
There are two main components of broker remuneration: an upfront commission, paid when the loan settles, and a trailing commission, paid annually for as long as the borrower holds the loan. When borrowers are refinancing a home loan and changing lenders, the new broker will earn a fresh upfront commission, while the previous broker's trail payments stop. The exact percentages and dollar caps are set by regulation and have changed significantly over the past decade.
Upfront vs trail commissions explained
Upfront commissions are calculated as a percentage of the loan amount, subject to a cap. Following reforms introduced after the Financial Services Royal Commission, the maximum upfront commission is tied to the loan size, with the cap indexed annually. Trail commissions, by contrast, are usually a smaller annual percentage of the loan balance and continue for the life of the loan, often 25 to 30 years.
The structure was reformed in 2018 and again in 2021, with the most significant change being the introduction of a Best Interests Duty. This legally obliges brokers to act in the borrower's best interests rather than simply recommending products that pay the highest commission. As a result, brokers must now document why a particular loan was recommended, demonstrating that it suits the borrower's circumstances, goals, and financial capacity.
The best interests duty and consumer protection
The Best Interests Duty, which took full effect in early 2022, sits at the centre of broker regulation. Under ASIC's Regulatory Guide 273, brokers must take reasonable steps to ensure that any credit recommendation is appropriate for the borrower. This includes verifying income, reviewing living expenses, stress-testing the borrower's ability to repay under higher interest rates, and comparing a meaningful sample of loans from across their panel rather than just one or two options.
Borrowers also benefit from mandatory comparison rate disclosure, which makes it easier to compare loans with different structures. Lenders must display a comparison rate alongside the headline rate, giving borrowers a single figure that reflects the interest rate plus most ongoing fees and charges. Combined with the Best Interests Duty, these rules have made the Australian market one of the more transparent mortgage industries in the world.
Comparing brokers, banks, and direct lenders
Borrowers in Adelaide, Perth, and other regional centres often weigh up whether to use a broker, walk into a bank branch, or apply directly to a lender online. Each channel has its own advantages and trade-offs.
| Channel | Cost to borrower | Product range | Personal guidance | Typical use case |
|---|---|---|---|---|
| Mortgage broker | Usually none | Broad panel across many lenders | High | Comparing many options, complex income, self-employed |
| Bank branch | None | Only that bank's products | Moderate | Existing relationship, simple application |
| Direct lender online | None | Only that lender's products | Low to none | Quick refinance, confident borrowers |
| Mortgage manager | None or fee | Wholesale products via a broker | Variable | Specialist lending, non-standard situations |
A broker is generally most useful when a borrower's situation does not fit a standard template, such as casual or contract workers, self-employed applicants, or those with multiple income sources. For straightforward applications, going direct to a bank can sometimes be faster and avoid the small risk of miscommunication between three parties rather than two.
When using a broker makes sense
A broker can add genuine value when the borrower is short on time, unsure which lender is likely to approve them, or seeking a competitive rate across a wide range of products. The situations below often justify using one:
- First home buyers who want guidance on federal schemes such as the First Home Guarantee or state-based stamp duty concessions available in Victoria, Queensland, or Western Australia.
- Self-employed borrowers who need help presenting irregular income, multiple entities, or recent tax returns to lenders.
- Property investors structuring loans across multiple properties and looking to optimise tax outcomes and cash flow.
- Homeowners considering refinancing to access equity, consolidate debt, or secure a lower variable rate.
- Buyers purchasing in competitive markets such as inner-city Sydney or Melbourne, where pre-approval speed and strong broker-lender relationships matter.
For borrowers who already know which lender they want and have a straightforward application, applying direct may be simpler and equally effective. The key is to remember that a broker's service is regulated, their advice must meet a legal duty, and their pay comes from the lender rather than from an extra fee at settlement.
