Choosing an aggregator
How to choose the best mortgage aggregator in Australia
The best mortgage aggregator is not necessarily the biggest, the cheapest or the one offering the longest list of services.
Last reviewed: October 2026
It is the aggregator whose commercial model, support, lender access, technology, compliance framework and culture best fit the way you want to run your broking business.
This guide explains what Australian mortgage brokers should compare before choosing an aggregator — or deciding whether their current aggregator is still right for them.
The short answer
What is the best mortgage aggregator in Australia?
There is no single mortgage aggregator that is best for every broker.
A broker building a large team may need something very different from an experienced solo broker who wants to retain control of their clients, trail book and income.
The right aggregator should provide the infrastructure you need without making it unnecessarily difficult to operate your own business.
For most brokers, the decision should consider:
- commission structure and fees;
- ownership of clients and trail;
- lender panel and accreditation;
- compliance support;
- technology and systems;
- access to experienced people;
- business-development support;
- professional development;
- community and culture;
- agreement terms; and
- what happens if you eventually decide to leave.
Start with the business model
Before comparing features, understand exactly how the aggregator gets paid.
Common arrangements may include:
- retaining a percentage of upfront commission;
- retaining a percentage of trail commission;
- charging a monthly fee;
- charging additional technology or administration fees; or
- combining fees with a commission split.
These differences can become significant as a broker's settlement volume grows.
Questions to ask
- What percentage of upfront commission do I retain?
- What percentage of trail do I retain?
- Is there a monthly membership or aggregation fee?
- Are CRM, software or platform charges additional?
- Are there joining, exit or administration fees?
- Are the quoted commissions gross or net?
- Does the commercial model change as my volume increases?
A low monthly fee can be expensive if a substantial percentage of commission is also retained.
Equally, a higher fixed monthly fee may represent good value for a broker who retains all commissions and uses the support provided.
What matters is the total economic effect, not one headline number.
Understand who owns the clients and trail
This should be established before signing an aggregation agreement.
Ask:
- Who owns the client relationship?
- Who owns the trail book?
- What happens to trail if I leave?
- Can trail be transferred?
- Are there restrictions on contacting existing clients after leaving?
- Can the aggregator buy or retain the trail under particular circumstances?
- Are there restraints that continue after termination?
Do not rely only on a sales conversation.
Read the agreement.
For an established broker, ownership and exit provisions can be just as important as the commission split.
Compare the lender panel — but look beyond the number
A large lender panel sounds attractive, but the number of lenders alone does not tell you whether the panel suits your business.
Consider the type of lending you actually write.
For example:
- residential lending;
- investment lending;
- self-employed borrowers;
- non-bank lending;
- commercial finance;
- asset and equipment finance; and
- specialist lending.
Ask
- Are my commonly used lenders available?
- Are the lenders relevant to the clients I serve?
- How are new lender accreditations handled?
- What happens to accreditation if I change aggregators?
- How quickly are accreditation issues resolved?
- Who helps when an unusual scenario arises?
Look carefully at the support model
“Support” is one of the most commonly used words in aggregation.
It can also mean very different things.
One aggregator may provide a central help desk.
Another may provide access to an allocated BDM.
Another may provide direct access to an experienced business owner or industry practitioner.
Consider what you actually want support with.
That might include:
- lender policy questions;
- difficult scenarios;
- compliance;
- business strategy;
- workflow;
- technology;
- file quality;
- marketing;
- referral relationships;
- professional development; or
- simply having an experienced person available when you need another opinion.
A useful question
Instead of asking:
“What support do you provide?”
ask:
“If I have a difficult scenario at 10am tomorrow, who will I actually speak to?”
That usually tells you much more.
Technology should make broking easier
Technology matters, but more software does not necessarily mean a better aggregator.
The systems should help you:
- manage clients;
- record compliance;
- research lending options;
- submit applications;
- collect documents;
- communicate with clients;
- manage the pipeline;
- monitor commissions; and
- operate efficiently.
Ask to see the actual systems before joining.
Consider:
- Is the CRM practical?
- Is data easy to find?
- Can workflows be automated?
- Is training provided?
- What integrations are available?
- Can your business data be exported?
- What happens to the data if you leave?
- Are systems secure and appropriately controlled?
The objective should be better broking, not technology for technology's sake.
Compliance should support good practice
Good compliance is not about creating unnecessary paperwork.
It should help a broker demonstrate that the client was properly understood, suitable options were considered and the recommendation was appropriately documented.
Compare:
- file-review processes;
- compliance training;
- audit support;
- escalation processes;
- documentation;
- privacy and cyber requirements; and
- access to practical guidance.
Ask how compliance issues are handled when a broker needs help — not only what happens when something goes wrong.
Consider professional development
The right aggregation relationship should help you become a better broker and a better business operator.
Professional development may include:
- lender policy;
- credit assessment;
- compliance;
- business development;
- technology;
- marketing;
- commercial finance;
- asset finance;
- client communication;
- cyber security;
- fraud prevention; and
- business management.
The value is not simply how many webinars appear on a calendar.
Ask whether the professional development is relevant, practical and usable.
Consider the community — but do not confuse activity with value
Some brokers want a large network.
Others prefer a smaller community where people know one another.
Neither is automatically better.
Consider whether you want:
- networking;
- peer discussion;
- scenario sharing;
- lender events;
- professional-development sessions;
- informal broker interaction; or
- a largely independent relationship.
For solo brokers in particular, access to other experienced brokers can reduce some of the isolation of running an independent business.
Read the agreement before you join
A good aggregation decision is partly about joining.
It is also about how easily you can leave.
Before signing, understand:
- agreement term;
- notice period;
- termination rights;
- client ownership;
- trail ownership;
- restraints;
- outstanding fee provisions;
- data rights;
- professional indemnity obligations; and
- what happens to active applications if you leave.
An attractive joining offer should never substitute for understanding the agreement.
Think about switching before you need to switch
Changing aggregators can involve:
- lender accreditation changes;
- credit representative arrangements;
- system migration;
- client records;
- commission arrangements;
- active applications;
- websites and disclosure material;
- insurance; and
- compliance onboarding.
That does not mean changing aggregators should be avoided.
It means it should be planned.
Boutique or large aggregator?
There are advantages to both models.
A larger aggregator may suit you if:
- scale is important;
- you want a very large network;
- you prefer centralised support structures;
- you need extensive corporate resources; or
- your business model aligns strongly with their systems.
A boutique aggregator may suit you if:
- personal access matters;
- you want people to know your business;
- you value continuity of support;
- you prefer a smaller broker community; or
- you want greater flexibility in the relationship.
The important question is not:
“Which model is better?”
It is:
“Which model is better for the way I want to operate?”
Commission split or flat fee?
This can have a substantial impact over time.
A commission split means the amount paid to the aggregator generally increases as your business settles more loans.
A fixed-fee model behaves differently: the agreed fee remains relatively predictable while the broker retains the commission, subject to the particular agreement.
Neither model should be assessed in isolation.
Compare:
- annual cost;
- five-year cost;
- services received;
- technology costs;
- support;
- trail treatment; and
- exit terms.
For an established broker writing significant volume, even a relatively small commission percentage can become a substantial business expense.
What should an experienced solo broker look for?
Solo operators often have different priorities from large broker businesses.
An experienced solo broker may place greater value on:
- keeping control of their business;
- retaining commissions;
- owning their clients and trail;
- direct access to experienced support;
- efficient systems;
- strong lender infrastructure;
- practical compliance assistance; and
- having support available without constant interference.
That is the part of the market Morbanx Aggregation was designed to serve.
Where Morbanx fits
Morbanx Aggregation is a boutique national aggregation business designed primarily for experienced independent mortgage brokers.
The model is built around three principles:
Keep what you build
Morbanx brokers retain 100% of their commissions and retain ownership of their clients and trail, subject to the terms of their agreement.
Remain independent
The broker operates their own business and makes their own business decisions.
Have experienced support available
Brokers have direct access to practical support across lending, compliance, business operations and professional development.
Morbanx operates as a sub-aggregator of Specialist Finance Group (SFG), combining a boutique support relationship with established aggregation infrastructure.
Who Morbanx is likely to suit
Morbanx is designed primarily for brokers who:
- have established industry experience;
- operate independently;
- predominantly write residential lending;
- want to retain control of their client relationships;
- value practical support;
- take compliance seriously;
- are open to improving their business; and
- prefer a high-touch relationship rather than feeling like a number.
It may not suit every broker.
And that is important.
Choosing an aggregator should be about fit rather than trying to convince every broker to join.
12 questions to ask any mortgage aggregator
Before making a decision, ask:

Frequently asked questions
What does a mortgage aggregator do?
A mortgage aggregator connects brokers with lender panels and typically provides infrastructure such as accreditation assistance, technology, commission processing, compliance support, training and other business services. The services and business models vary considerably between aggregators.
Do mortgage brokers need an aggregator?
A broker needs the appropriate licensing or credit-representative arrangement, lender access and accreditation, and systems to conduct their business. Many Australian brokers obtain these through an aggregator.
Which mortgage aggregator is best in Australia?
There is no single best aggregator for every mortgage broker. The right choice depends on the broker's business model, volume, lender requirements, preferred support model, technology needs, costs and ownership arrangements.
Should I choose an aggregator based on commission split?
Not by itself. Commission retention is important, but brokers should compare the total cost alongside support, lender access, technology, compliance, ownership and agreement terms.
Is a flat-fee aggregator better than a commission-split aggregator?
It depends on the broker. A fixed-fee model can become attractive as settlement volumes increase because the aggregation cost does not automatically rise in proportion to commissions. The services received and the overall agreement still need to be considered.
Who owns my trail book when I leave an aggregator?
That depends on the aggregation agreement. Brokers should establish trail ownership, payment arrangements and exit provisions before joining.
Is changing mortgage aggregators difficult?
It can involve lender accreditations, licensing arrangements, data, systems, commissions and active applications. A planned transition can substantially reduce disruption.
What should I ask an aggregator before joining?
At minimum, ask about commissions, fees, trail ownership, client ownership, lender access, technology, compliance, support, agreement terms and exit arrangements.
What is the difference between a boutique and large aggregator?
A large aggregator may offer scale and broad corporate resources. A boutique aggregator may provide more direct access and a more personal relationship. Neither is inherently better; the appropriate model depends on the broker.
Is Morbanx Aggregation suitable for new brokers?
Morbanx is primarily designed for brokers with established experience. New-to-industry brokers may require structured mentoring arrangements in addition to aggregation support.
Choosing an aggregator should be a business decision
Your aggregator can influence your income, systems, lender access, compliance environment and day-to-day experience for years.
Take the time to compare the whole relationship.
Not just the commission percentage.
Not just the software.
Not just the sales pitch.
The best mortgage aggregator for you is the one that allows you to run the business you want to build.
