What a Mortgage Broker Is Legally Required to Do for You

Most people choose a broker on a recommendation and a feeling. Very few know that Australian mortgage brokers carry a legal obligation that bank lending staff do not.

That obligation changes what you can reasonably expect and what you can hold them to. This guide covers the duty, how brokers are paid, and the questions worth asking before you engage one.

Key Takeaways

• Since 1 January 2021, Australian mortgage brokers have been subject to a Best Interests Duty under the National Consumer Credit Protection Act.
• Where a conflict exists, brokers must prioritise your interests over their own.
• That duty does not apply to lending staff employed by a bank.
• Brokers are generally paid commission by the lender, and clawback arrangements are worth asking about.
• The duty does not guarantee the cheapest loan, and it does not remove your need to compare.

The Duty Most Borrowers Have Never Heard Of

On 1 January 2021, a Best Interests Duty came into force for Australian mortgage brokers. It sits in Part 3-5A of the National Consumer Credit Protection Act 2009 and arrived as a direct response to Recommendation 1.2 of the Hayne Royal Commission.

In plain terms, a broker providing credit assistance must act in your best interests. ASIC set out its expectations in Regulatory Guide 273, which describes what it looks for when assessing compliance.

Notably, there is no safe harbour. The law does not list a set of steps that automatically count as compliance, so brokers have to take whatever steps are actually necessary in your circumstances.

What That Means in Practice

ASIC’s guidance describes three broad stages. A broker gathers information about you and your situation, uses that information to assess what credit assistance would be in your best interests, and then presents recommendations with reasons.

Cost is central to that assessment. Interest rate, fees, charges and repayment size are factors ASIC says should generally be prioritised, though cost is not the only consideration.

Where non-cost features matter to you, they can properly be part of the assessment. The test is whether those features offer genuine value or net benefit relative to the alternatives, rather than simply being available.

This sits on top of responsible lending obligations rather than replacing them. The two are complementary, and a broker has to satisfy both.

The Conflict Priority Rule

The second limb is arguably more useful to know. Where a conflict exists between your interests and the broker’s own interests, the broker must prioritise yours.

That matters because commission rates differ between lenders. A broker cannot lawfully steer you toward the lender that pays them more when a better option for you exists.

The duty also cannot be contracted out of. Anti-avoidance provisions in the same Act mean a broker cannot use an agreement or arrangement to sidestep the obligation.

Why the Same Rule Does Not Apply at the Bank

This is the part that surprises people. The Best Interests Duty applies to mortgage brokers and their credit representatives, and in practical terms it does not extend to loan officers employed directly by banks and other lenders.

A bank employee is selling that bank’s products. They are subject to responsible lending rules and general conduct obligations, but they are not required by this duty to act in your best interests when recommending a loan.

That is not an argument that banks behave badly. It is simply a difference in the legal standard, and it is worth understanding before you decide which door to walk through.

How Brokers Actually Get Paid

Most residential mortgage brokers charge the borrower nothing and are paid commission by the lender instead. There are typically two components: an upfront commission based on the loan amount drawn down and a trail commission paid annually while the loan remains active.

Ask about clawback. If a loan is repaid or refinanced within a set period, commonly the first one to two years, the lender can reclaim part or all of the upfront commission from the broker.

Some brokers pass that cost on to the client, and some absorb it. Whichever applies, it should be disclosed in the credit guide and the agreement you sign, so read that section rather than skipping it.

Brokers also have to disclose their remuneration. If a fee is charged directly to you, which is more common in complex or commercial matters, it must be set out clearly before you proceed.

The Lender Panel Question

Access varies considerably between brokers. Some have a panel of a handful of lenders and others compare across dozens, which directly affects the range of options they can put in front of you.

Ask how many lenders are on the panel and whether any are related to the brokerage through ownership. Neither answer is disqualifying, but both change how you read a recommendation.

Ask what happens if the right product sits with a lender they cannot access. A straight answer to that question tells you a lot.

Why Location Still Matters

State-based rules are one reason to think locally. Stamp duty, concessions and first home owner grants differ by state, and eligibility criteria change more often than most buyers expect.

A mortgage broker in Adelaide deals with South Australian thresholds and grant conditions routinely, where someone working mainly interstate may not. 

That familiarity matters most for first home buyers, where a missed concession is real money.

Local knowledge extends to lender behaviour too. Valuation outcomes and lender appetite can vary by suburb and property type, and a broker who works a market regularly tends to know which lenders are comfortable where.

The Duty Gives You Recourse

A legal obligation is only useful if something sits behind it. Australian credit licensees must belong to the Australian Financial Complaints Authority, which handles disputes between consumers and financial firms.

That means a Best Interests Duty breach is not just a matter of leaving a poor review. You can raise the complaint with the broker first, and escalate to AFCA if it is not resolved, at no cost to you.

ASIC also monitors conduct in this area and has said it intends to look closely at outcomes rather than paperwork. Breaches of the anti-avoidance provisions can carry civil penalties.

Keep your records. The recommendations you were given, the reasons attached to them and the options you were shown are the evidence any complaint would rest on.

What to Bring to a First Meeting

Preparation shortens the process considerably. Bring recent payslips or, if self-employed, two years of tax returns and financial statements, along with bank statements covering the last few months.

Have a list of existing debts including cards, personal loans, car finance and buy now pay later accounts. Brokers assess the whole picture, and undisclosed commitments surface at the lender stage anyway.

Come with your goals stated plainly. Whether you value the lowest rate, an offset account, the ability to make extra repayments or fixed certainty changes what suits you, and the assessment is only as good as what you tell them.

What a Broker Cannot Do for You

Be clear about the limits. The Best Interests Duty does not guarantee you the lowest rate available in the market, because no broker has access to every lender.

It also does not make approval certain. Lenders assess on their own criteria, and a broker’s role is to match you to a likely fit rather than to override a credit decision.

Nor does it replace your own comparison. A broker is a strong resource and the duty gives you real recourse, though you remain the person signing a thirty-year commitment.

Conclusion

The Best Interests Duty is the most useful thing a borrower can understand about how broking works in Australia. It is a legal obligation with a regulator behind it, and it applies to brokers rather than to bank staff.

Ask about the lender panel, ask how clawback is handled, and read the credit guide before you sign it. Those three steps tell you more about a broker than any review page will.

Mortgage Broker FAQs

What is the Best Interests Duty? A legal obligation requiring Australian mortgage brokers to act in the best interests of consumers when providing credit assistance. It commenced on 1 January 2021 under the National Consumer Credit Protection Act.

Does the Best Interests Duty apply to banks? In practical terms, no. It applies to mortgage brokers and credit representatives rather than to loan officers employed directly by a bank or lender.

What is the conflict priority rule? Where the broker’s interests conflict with yours, they must prioritise yours. It means commission differences between lenders cannot lawfully drive a recommendation.

Does a broker have to find me the cheapest loan? No. The duty requires them to act in your best interests across cost and suitability, but no broker accesses every lender in the market.

How much does a mortgage broker cost? Most residential brokers charge borrowers nothing and are paid commission by the lender. Any fee charged directly to you must be disclosed before you proceed.

What is clawback? Where a loan is repaid or refinanced early, commonly within one to two years, the lender can reclaim commission from the broker. Ask whether that cost would be passed on to you.

How many lenders should a broker have access to? There is no set number, and panels range from a handful to several dozen. Ask for the figure and whether any panel lenders are related to the brokerage.

Can a broker guarantee loan approval? No. Lenders make their own credit assessments against their own criteria.

Why does a local broker matter? Stamp duty, concessions and first home owner grants are set at state level, and lender appetite can vary by location and property type.
