What a mortgage broker actually does (and how brokers are paid)

Most Australian borrowers now arrange their home loans through a mortgage broker rather than walking into a bank branch — yet plenty of people still are not quite sure what a broker actually does, who pays them, and whether the service is genuinely on their side. Straight answers to all three, below.

What a broker actually does

A mortgage broker is a credit professional who works for you across a panel of lenders rather than for any single bank. The job, end to end:

• Understands your situation — income, debts, deposit, plans — and what you are trying to achieve.
• Assesses your borrowing position properly, the way a lender will, before anything touches your credit file. (Start with our [borrowing capacity calculator](/calculators/borrowing-capacity), then let a broker pressure-test it.)
• Matches you to lender policy — knowing which lenders shade your overtime least, accept your probation period, or take your ABN history — which is often the difference between approval and decline.
• Structures the loan — fixed/variable split, offset and redraw, loan term, ownership structure for [investment purchases](/loans/investment-loans).
• Prepares and lodges the application, packaging your documents the way the lender's assessors want to see them.
• Manages the process to settlement — chasing the lender, handling valuation issues, coordinating with your conveyancer.
• Reviews the loan afterwards — repricing requests and refinance reviews over the life of the loan.

Brokers must be licensed (or act as credit representatives under a licence) and operate under the National Consumer Credit Protection Act, with the same responsible lending obligations as lenders.

Best Interests Duty: the key difference from bank staff

Since 2021, mortgage brokers have been subject to a legislated Best Interests Duty (BID): when recommending a home loan, a broker must act in the best interests of the customer, and where there is a conflict, prioritise the customer's interests over their own. Bank lending staff are not subject to this duty — a bank employee can only offer that bank's products and has no obligation to tell you a competitor would suit you better. That does not make bank staff bad actors; it means the two channels have structurally different obligations. A broker who cannot find you a suitable loan is required to say so, and a broker recommending one loan over another should be able to explain why it is in your interests — ask, and expect a clear answer.

How brokers are paid

This is the part everyone should understand before using any broker, so here it is plainly. For standard residential home loans, brokers are typically paid by the lender, not by you — an upfront commission when the loan settles and a smaller ongoing trail commission while the loan remains in place. In most cases there is no fee charged to the customer for arranging a standard residential loan, though practices vary and some brokers do charge fees for complex or low-value scenarios — any fee must be disclosed and agreed before you commit. Commissions themselves must be disclosed to you, and reforms following the banking Royal Commission removed the structures that most distorted advice (such as volume bonuses). Two honest caveats: commission only exists on loans from lenders the broker is accredited with, so a broker's "market" is their panel, not every lender in Australia; and because commission is broadly similar across mainstream lenders, the financial incentive to steer you to one big lender over another is limited — but you are entitled to ask any broker exactly what they will be paid on your loan, and a good one will show you.

Broker vs going direct to your bank

Going direct can be perfectly fine — particularly if your situation is simple, your bank's policy suits you, and you have compared alternatives yourself. The trade-offs:

• Choice: a bank offers its own products; a broker compares across a panel of lenders, from majors to non-banks.
• Policy knowledge: the biggest hidden value. Lenders differ on income shading, probation, self-employment and expenses, and a misfired application leaves a credit enquiry behind — see [loan application mistakes](/articles/credit-and-approval/loan-application-mistakes).
• Duty: BID applies to the broker, not to bank staff.
• Pricing: brokers routinely request discretionary pricing from lenders; banks do not always volunteer their sharpest rate to walk-in customers.
• Effort: one conversation and one document set with a broker, versus repeating the exercise per bank on your own.

When a broker adds the most value

Brokers help most when the answer is not obvious:

• Non-standard income — self-employed, contract, casual, heavy overtime or bonus income, where lender policy differences are largest.
• Marginal serviceability — when one lender's calculator says no and another's says yes.
• Small deposits and LMI strategy — navigating [LVR thresholds](/articles/home-loans/understanding-lvr), guarantor options and government schemes.
• Credit history wrinkles — past defaults or thin files, where choosing the wrong lender wastes an enquiry.
• Refinancing — testing whether your loyalty is being taxed and handling the switch end to end; see [refinancing options](/loans/refinance).
• First home buyers — sequencing grants, duty concessions, pre-approval and the purchase itself; start with [first home buyer loans](/loans/first-home-buyers).

If your situation is genuinely vanilla — strong PAYG income, big deposit, clean credit — a broker's value is more about pricing, structure and saved legwork than about getting approved.

What to expect from a first conversation

A proper first meeting costs you nothing but an hour: you talk through your goals and finances, the broker runs a preliminary assessment, explains the realistic lender options and their reasoning, and gives you a document checklist. There is no obligation, and nothing is lodged or recorded on your credit file at that stage. Treat it as a second opinion even if you intend to go direct — worst case, you walk away better informed.

Talk it through with a broker

If you want a clear read on what you can borrow, which lenders fit your situation, and what it will cost — asked and answered plainly — [get in touch](/contact) or [start online](/apply) whenever you are ready.
