What determines a mortgage broker's salary in Australia? There isn't a fixed figure. Most brokers aren't salaried in the traditional sense — they're paid commission by their aggregator, made up of an upfront payment when a loan settles and ongoing trail commission for as long as the client stays with that lender. Some newer brokers are paid a base salary plus commission while they build a client base. Most experienced brokers work on commission alone.
So broker income isn't one number. It's built out of a handful of moving parts:
Here's how each of those actually plays out.
Lenders pay commission to the broker's aggregator, who passes a share through to the broker or brokerage. The client never pays a cent directly for the advice.
That commission comes in two parts:
Brokers who protect their client relationships over years build a second, quieter income stream most people never think about: trail.
It depends on your employment setup. Some brokerages bring newer brokers on with a base salary plus a share of commission while they build a client base. Others operate as fully self-employed practitioners or business owners writing loans under their own mortgage broker business model, keeping a larger share of every commission dollar in exchange for carrying more of the risk and the overheads.
Every broker in Australia operates under an aggregator, which gives you access to a panel of lenders, compliance support, and the technology stack you write loans through. In return, the aggregator takes a share of the commission before the rest flows to you.
The size of that split is set out in your individual aggregator agreement, and it varies broker to broker based on:
Two brokers writing similar volume can end up with genuinely different take-home outcomes purely because of the agreement each is operating under. Most new brokers sign whatever agreement is put in front of them and never revisit it — understanding what you're actually getting for the split you're paying, and knowing when it's worth having that conversation again, is part of running the business side of broking properly.
Volume matters. More settlements and larger average loan sizes generally mean more commission, both upfront and in trail. But volume by itself is a fragile way to build income — chase raw numbers without the relationships behind them, and every quiet month in the market hits your income directly.
The brokers who build genuinely stable income are the ones whose volume comes with retention attached. Existing clients refinance, buy investment properties, refer their network, and stay on the books long enough for trail commission to actually mean something. That's reputation compounding, not just a bigger pipeline.
Experience plays into this too — not because tenure alone pays more, but because experienced brokers have usually already fixed the parts of their process that cost newer brokers deals: faster turnaround, cleaner applications, stronger lender relationships.
Gross commission and take-home income are two different numbers, and the gap between them is where a lot of brokers get caught out. Running a brokerage, even as a sole operator, comes with real costs:
Brokers who budget for these costs rather than absorbing them as a surprise end up with a much clearer picture of what they're really earning. The moment you start managing your brokerage like a business rather than a job, the cost side stops feeling like it's eating your income and starts looking like something you can control.
The biggest driver of long-term broker income isn't commission structure — it's whether you've built a business around yourself or you're still working inside one deal at a time.
Ruan Burger, founder and head coach at Success & Broker and BBA 2024's Industry Thought Leader of the Year, built the coaching program around exactly this gap. Brokers with strong technical skills often plateau not because they can't write good loans, but because there's no consistent lead flow, no repeatable process, and no time freed up from admin to actually have client conversations.
Tools like The Broker Journal exist for exactly this reason, giving brokers a practical way to track and build the habits that turn a good month into a repeatable one. It's the same thinking behind the difference between a job and a career as a broker: a job pays for the hours you put in today, a career compounds.
For context on how commission and remuneration are structured across the industry, the MFAA's broker remuneration factsheet is a useful independent reference.
Some do, some don't. Brokers employed by a brokerage while they build experience are sometimes paid a base salary plus a share of commission, while self-employed brokers and business owners generally work on commission alone through their aggregator agreement.
Lenders pay commission to the broker's aggregator when a loan settles, and again as trail commission for as long as the loan balance remains with that lender. Clients don't pay the broker directly.
Yes, but volume alone isn't the full picture. Income holds up best when volume comes with client retention and referrals attached, since that's what keeps trail commission and repeat business flowing during quieter months.
Upfront commission is a one-off payment made when a loan settles. Trail commission is paid on an ongoing basis, calculated against the outstanding loan balance, for as long as the client stays with that lender.
Yes, significantly. The percentage split is set in your individual agreement and can vary based on your production level and tenure, meaning two brokers writing similar volume can end up with different take-home outcomes purely due to their agreement terms.
Yes. Commission structure and aggregator splits set the ceiling, but consistent lead flow, repeatable processes, and time freed up from admin are what most brokers are actually missing — and those are the levers coaching is built to fix.
There's no single mortgage broker salary because there's no single mortgage broker business model. It's commission structure, the aggregator agreement you're under, the volume and retention you build, the costs you carry as a business, and underneath all of it, whether you've got real systems running or you're starting from scratch every month.
That last part is the one within your control. If you're ready to look at your brokerage as an actual business rather than a collection of deals, book a discovery call with our mortgage broker business coaching team and let's work out what's actually holding your income back.
