The mortgage broking industry in Australia has evolved rapidly over the past decade. With rising regulatory expectations, increased competition, and a growing emphasis on client-first service, mortgage brokers are seeking more efficient ways to run their businesses. That’s where mortgage aggregators come in. But what is a mortgage aggregator exactly, and why are they so essential to brokers in 2025?
Imagine being a mortgage broker with access to dozens of lenders, a reliable commission management system, compliance tools at your fingertips, and marketing support that keeps your business relevant in a competitive market.Â
That’s essentially what a mortgage aggregator offers. In this guide, we unpack the role of aggregators in the Australian mortgage industry, the benefits and costs, and how to choose the right one for your business.
Whether you’re just entering the broking space or considering a switch from your current provider, understanding how mortgage aggregator Australia models work in 2025 can set you up for long-term success.
What Is a Mortgage Aggregator?
At its core, a mortgage aggregator acts as a middle layer between mortgage brokers and lenders. Aggregators offer brokers access to a panel of lenders, provide essential backend services like software platforms and compliance tools, and manage the flow of commission payments.
In simple terms, a mortgage broker aggregator gives brokers the tools and relationships needed to operate more effectively and competitively without having to build all that infrastructure independently.
Aggregators aren’t lenders themselves. They don’t provide the mortgage products directly but enable brokers to offer a broad range of loans to their clients by partnering with banks, credit unions, and non-bank lenders.Â
According to recent industry reports, the mortgage broker market size in Australia surged to $6.2 billion in 2025, a 12.9% rise from the previous year. This rapid growth highlights the increasing importance of aggregator support in a competitive lending environment.
How Does a Mortgage Aggregator Work in Australia?
When a broker partners with an aggregator, they typically sign an agreement that allows them to:
- Access a panel of approved lenders
- Use proprietary or white-labelled CRM and loan lodgement systems
- Receive support in compliance and training
- Get assistance with marketing and branding (depending on the aggregator)
This model benefits new brokers by offering a plug-and-play infrastructure. Experienced brokers benefit by being able to scale faster while keeping operational costs lower.
Services Typically Provided by Aggregators
The exact services vary by aggregator, but most provide:
- Lender Access:
A large and diverse panel of lenders, including major banks, second-tier banks, and non-bank lenders. - CRM and Technology Tools:
Cloud-based loan origination systems that streamline applications, compliance checks, and document management. These tools form the core of many mortgage back-office solutions, helping brokers reduce manual admin work. - Compliance and Risk Management:
Support to meet ASIC obligations, including adherence to the Best Interest Duty (BID). - Commission Management:
Aggregators collect upfront and trail commissions from lenders, then distribute them to brokers. They often provide breakdowns and reports. - Training and Development:
CPD-accredited training programs, workshops, and business mentoring. - Marketing and Business Support:
Assistance with branding, lead generation, and digital tools to grow a broker’s presence.
Benefits of Working with a Mortgage Aggregator
- Efficiency:
Aggregators provide ready-to-use systems, reducing setup time and admin burdens. This model often functions like an outsourced mortgage service, allowing brokers to focus more on client relationships and less on backend operations. - Lender Choice:
Brokers can offer more options to their clients, increasing the likelihood of finding the right loan. - Regulatory Confidence:
Staying on top of compliance and licensing requirements becomes more manageable. - Business Support:
From training to lead generation, brokers are often better equipped to grow sustainably.
Networking: Some aggregators host conferences and events that provide valuable industry connections and insights.
According to a recent report by Mordor Intelligence, the Australian mortgage lending market was valued at AUD 348.68 billion in 2024 and is projected to grow to AUD 912.64 billion by 2034.Â
This steady expansion reflects increased housing demand and rising broker activity, indicating that the need for aggregator services will only continue to rise. In addition, government-backed programs such as the First Home Owner Grant (FHOG) and the First Home Loan Deposit Scheme (FHLDS) are further boosting homebuyer engagement and contributing to industry momentum.

Things to Consider When Choosing a Mortgage Aggregator
With growing broker numbers and tighter regulations, choosing the right aggregator is a crucial decision. Consider these factors:
- Fee Structures: Are there upfront onboarding fees? What ongoing platform or service charges apply?
- Commission Splits: Do you retain 90%, 85%, or some other percentage of commissions? Are there volume targets?
- Technology Stack: Is the platform intuitive, fast, and mobile-friendly? Is it integrated with other fintech tools?
- Lender Panel Diversity: Do they offer access to both major and niche lenders?
- Training and CPD: Are they actively helping you grow in skill and compliance?
- Data Ownership: Can you take your client data with you if you switch aggregators?
Brokers should request detailed breakdowns of mortgage broker aggregator fees before signing any agreement.
Aggregator Fees and Commission Splits
Aggregator revenue is primarily derived from taking a small share of the commissions brokers earn. The typical commission split is around 85/15 or 90/10, with some boutique aggregators offering 95/5 for high-volume brokers. In addition
to splits, other common costs include:
- Platform fees (monthly or per user)
- CRM access costs
- White-labelling or brand support fees
- Exit or switching fees
It’s important to read the fine print and understand the total cost of doing business with an aggregator. Comparing mortgage broker aggregator fees across providers can reveal hidden costs or obligations that impact your bottom line.
Regulatory Considerations in 2025
As of 2025, mortgage brokers and aggregators operate in a tightly regulated environment. ASIC continues to oversee conduct, while the Best Interest Duty remains a cornerstone of compliant broker operations. Aggregators play a crucial
role in ensuring brokers stay compliant:
- They provide systems that prompt brokers to meet BID.
- They offer audit support and documentation.
- Many offer training to help brokers meet their CPD requirements.
Compliance isn’t just about avoiding penalties – it’s also about building trust with clients, which is essential in a reputation-driven industry.
Pros and Cons of Using a Mortgage Aggregator
Pros:
- Faster go-to-market for new brokers
- Shared resources lower operational costs
- Enhanced credibility through known aggregator networks
- Tools to help meet regulatory requirements
Cons:
- Revenue-sharing reduces take-home income
- Some brokers feel locked into platforms
- Higher costs for low-volume or niche brokers
Your experience will largely depend on the aggregator’s culture, contract terms, and support quality.

Mortgage Aggregators vs Broker Groups: What’s the Difference?
While both models support mortgage brokers, broker groups (like Aussie or Mortgage Choice) often operate under a franchise-style system with stronger branding, while mortgage aggregators offer more autonomy. A broker working with an aggregator
might trade under their own brand and have broader lender access, while broker groups may offer fewer lenders but provide stronger consumer marketing support.
Is an Aggregator Right for Your Brokerage?
If you’re an independent broker looking to scale, offer more loan options, or reduce your admin burden, partnering with a broker support services provider
such as an aggregator mortgage broker model is almost essential. However, the right fit depends on your business goals, support needs, and willingness to share revenue. Ask yourself:
- Do I want to grow fast or maintain a lean solo practice?
- How important is marketing and branding support?
- Am I comfortable meeting volume targets?
The answers will guide your decision.
Final Thoughts for 2025

a potential RBA cash rate cut. Choosing the right mortgage broker aggregator isn’t just about cost, it’s about partnership. The best aggregators act as allies in your growth journey, offering more than just software or lender panels.
They provide guidance, training, and long-term value. As the Australian market continues to evolve, knowing what is a mortgage aggregator and how to leverage one could be the defining factor in your brokerage’s success.
