Best mortgage aggregators in Australia, compared.

‘Which is the best mortgage aggregator in Australia?’ is one of the most-searched questions in broking — and the honest answer is: it depends entirely on you. A broker writing $2M a month with a complex commercial book needs something different from a new-to-industry broker settling their first deals. So instead of a ranking that pretends otherwise, here's how to actually evaluate the field.

The Australian aggregator landscape

Australia has a mature aggregation market. The larger established networks include AFG, Connective, LMG (Loan Market Group), Finsure, Specialist Finance Group (SFG) and Outsource Financial, among others. More recently, flat-fee models such as ExBanqi have emerged, charging a fixed subscription rather than a commission split. Each has genuine strengths; the differences that matter to your bottom line come down to a handful of variables.

The five variables that actually matter

Ignore the brochures and compare every aggregator on the same five axes:

• Fee model — split vs flat fee. The single biggest driver of cost. A percentage split scales with your success; a flat fee doesn't. Model the real dollar figure at your volume, not the headline percentage.
• Lender panel. Size matters less than fit: does it cover the lenders your clients actually need, and is there any preferred-lender pressure steering you?
• Technology. Is the CRM included or a paid add-on, and is it modern? You live in this software every day.
• Lock-in & notice. Fixed terms and exit clauses reduce your leverage. Month-to-month keeps an aggregator earning your business.
• Support. Direct, knowledgeable support versus a tiered ticket queue changes how fast deals move.

Split model vs flat-fee model

Most of the established networks operate on some form of commission split — a percentage of your upfront and trail, sometimes with fee caps or tiered rates at higher volumes. It's a proven model, and for lower-volume brokers the absolute dollar cost can be modest.

A flat-fee model inverts the economics: you pay a fixed subscription — in ExBanqi's case $990/month + GST — and keep 100% of your commissions. The crossover point is volume. Below roughly $1M/month in settlements, a split can be cheaper in absolute terms; above it, a flat fee usually wins, and the gap widens as your trail book grows. We walk through the exact numbers across three broker profiles in flat fee vs commission split: we ran the numbers.

How to run your own comparison

Do this before you talk to anyone's BDM:

• Calculate your annual commission — upfront plus trail — at your current volume.
• Apply each aggregator's model to that figure: a split percentage, or a flat annual fee.
• Add the extras — CRM, lodgement, marketing levies, per-transaction charges — that some models bundle and others bill separately.
• Project it over five years, allowing for trail-book growth. The compounding is where split and flat-fee models diverge most.

Our savings calculator does this maths for the flat-fee comparison in about two minutes, and the comparison page lays the models out side by side.

Where ExBanqi fits

We're not for everyone, and we say so plainly. ExBanqi is built for established, independent brokers writing real volume who want to keep 100% of their commission and run their business on institutional infrastructure — SFG's 70+ lender panel, Salestrekker 2.0, and ex-banker support — without a percentage split. If you're brand new to the industry or need intensive hand-holding through your first year, a traditional aggregator with a split model may suit you better today. When your volume grows, the maths will be waiting.

The bottom line

There is no universal ‘best mortgage aggregator’ — there's the best fit for your volume, your clients and your ambitions. Compare on the five variables, run your own numbers over five years, and verify every term directly. Do that, and the right answer for your business becomes obvious — whoever it turns out to be.
