Australian mortgage brokers mostly earn lender-paid upfront and trail commission paid through their aggregator, so the models in this article’s title describe two deliberate departures from that default. A client-paid flat fee is a fixed disclosed amount charged for your service regardless of loan size. Commission sharing means splitting your commission under a written arrangement with another appointed representative or with your licensee.
Each model changes your income shape, your target client and your compliance paperwork. This article explains how the three approaches work in an Australian credit context and where each fits. It then covers what they cost you and the disclosure duties that apply whichever one you run.

Overview of Brokerage Compensation Models
Lender-paid commission remains the dominant income source for Australian brokers because it costs the client nothing at settlement and scales with loan size through upfront and trail components. Its drawbacks are equally well known: income depends on settlements and clawback terms, and clients sometimes assume free advice has a hidden catch.
The two alternatives trade those characteristics differently. Flat fees give predictable income per engagement but charge the client directly. Commission sharing keeps lender-paid income while spreading it across a team or referral partner, which suits group structures but requires precise documentation.
Recent Trends and Changes in Brokerage Models
Much of the online commentary about fee-model disruption describes United States real estate: legal challenges to listing commissions and flat-fee agencies such as Trelora, Houwzer and Redfin are US property-agency stories. They make interesting reading but they do not govern Australian mortgage brokering, which sits under the NCCP and ASIC’s guidance rather than US listing rules.
Locally, the measurable trend is channel growth rather than a fee revolution. MFAA figures for the March 2026 quarter put brokers at 81.0% of new residential lending, which says nothing by itself about how individual brokers charge. No regulator has announced a shift away from lender commission, so treat any confident claim that flat fees are taking over as opinion.
Advantages of Flat Fee Models
Charging an agreed fee for defined work gives clients certainty and can build trust, because the number appears before any work starts and cannot grow with the loan amount. It also decouples your income from settlement timing, which smooths cash flow across a year.

Flat fees suit straightforward engagements with clear boundaries: a complex commercial application priced as a project, or a self-employed client whose file needs unusual preparation work. The client knows the cost, and you know the work is funded whether or not a particular lender’s commission makes the file attractive.
Challenges and Disadvantages of Flat Fee Models
Pricing risk moves to you. Set the fee too low and complicated files lose money; set it too high and price-sensitive clients walk. High-value standard residential loans are the weak spot, because a client paying $3,000 alongside a large loan will reasonably ask why the bank pays you nothing.
Volume becomes the business constraint. Flat-fee practices typically need more engagements per month to match commission income, which changes staffing and marketing economics. And remember that any fee arrangement never transfers clawback exposure away from your aggregator agreement: if the loan unwinds, the commission recovery follows its contract regardless of what the client paid you.
How Commission Sharing Works
Commission sharing fits businesses where several people contribute to one book: a licensee supporting authorised credit representatives, or partners splitting a joint pipeline. The split lives in a written agreement that names who receives what, when it is paid and what happens to trail and clawback.
The common mistake is running informal splits off a whiteboard. Without written terms, disputes over trail after someone leaves the group become almost impossible to resolve cleanly, and your licensee may have approval conditions you have not checked.
Choosing the Model That Fits
- Client base: Budget-conscious borrowers with simple needs respond to flat fees. Clients with complex, high-value lending rarely accept paying on top of standard arrangements.
- Cash-flow tolerance: Commission suits practices that can carry lumpy income; flat fees suit those needing predictable monthly revenue.
- Team structure: Sharing arrangements suit groups; sole operators gain little from them.
- Service definition: A flat fee demands a clear scope document so clients know exactly what is included.
Disclosure Duties for Every Model
Whichever way you charge, the Credit Guide carries the disclosure. Lender commissions, client fees and sharing arrangements all belong there in plain language. Best-interests duty does not bend to your revenue model either: the suitable-loan test applies identically whether you earn commission, a fee or both. After-sales personal financial questions still need an AFSL holder or a referral.
Your Next Step
If you are weighing a change, model it before announcing it. Take last financial year’s settled loans, calculate total commission received including trail, then recalculate the same book at your candidate flat fee and at your proposed split. Include clawback from unwound loans in every scenario. If the numbers work within ten percent, draft the scope documents and update your Credit Guide wording; if they do not, stay with commission and revisit in twelve months. The right choice is the one your actual book supports, not the one trending in overseas headlines.
