Starting a mortgage broker business in Australia comes down to five things done in order: the right qualification, an authorisation to write credit, an aggregator agreement, enough working capital to survive the commission lag and compliance systems from day one. Skip any of the five and the others do not matter.
This guide walks through each step with the specific requirements and decisions involved, so you can map your own launch sequence against it.

The market you are entering
Broking remains a growing channel: intermediaries settled 81.0% of new residential lending in the March 2026 quarter according to MFAA industry data, so borrowers clearly want broker service. That demand supports a new mortgage broker business, but it also means established competitors already hold the referral relationships you will need time to build.
Qualifications and authorisation
Entry requires the Certificate IV in Finance and Mortgage Broking, currently FNS40821 on the National Training Register; older course codes such as FNS40815 have been superseded. The Diploma of Finance and Mortgage Broking Management sits above it, and if you join the MFAA on the Certificate IV alone you must complete the Diploma within twelve months.
To write loans as a mortgage broker you either hold an Australian Credit Licence (ACL) or authorise as a credit representative under someone else’s, which is the faster route most new entrants take. You will also need background checks, professional indemnity insurance, ongoing Continuing Professional Development, and association membership such as the MFAA or the Finance Brokers Association of Australia, whose CPD requirements apply across the membership year.
A business plan built around the cash-flow gap
Commissions trail settlements by weeks or months, and trail income builds over years, so the plan’s central number is how long you can operate before commissions cover costs. Itemise setup spending: qualification top-ups, licensing and membership fees, insurance premiums, technology and marketing, plus recurring commitments such as aggregator fees that arrive whether or not you have settled a loan that month. Define the target market narrowly enough that your first-year marketing can actually reach it.

A common mistake at this stage is planning revenue from day one. Most brokerages take six to eighteen months to reach sustainable volume, and the ones that survive planned for that gap explicitly rather than discovering it.
Structure and registration
Sole trader keeps setup simple but exposes personal assets; a company or trust structure limits liability and suits multiple-director setups at the cost of administration and accounting fees. Take the structure question to an accountant who understands broking businesses before you register anything, because changing structures after lodging is more expensive than choosing correctly once.
Compliance from day one
The NCCP Act governs every file you write: responsible lending inquiries, verification, suitability reasoning and disclosure. The Privacy Act covers client data and the Anti-Money Laundering and Counter-Terrorism Financing regime adds its own reporting duties, covered further in our guide to AML/CTF obligations. ASIC’s advertising rules also reach your website and social accounts from launch. Build record-keeping habits into your process templates now; retrofitting them after your first hundred files is far harder.
Winning the first clients
Referral relationships pay fastest: local real estate agents, accountants and conveyancers send clients to brokers they trust, so pick a handful of potential referrers and invest in those relationships deliberately. Inbound takes longer but compounds: local search visibility built through consistent SEO work brings clients researching before they call. Franchise groups offer a shortcut to systems, brand recognition and structured Networking opportunities in exchange for fees and less independence, which suits some first-time principals better than going alone.
Choosing an aggregator
Your aggregator supplies lender accreditations, commission processing, software and support, so the choice shapes what you can offer. Compare commission splits against fee-based models, panel breadth for your target market and the CRM or compliance tooling provided, then weigh how useful each panel’s business development support actually is. Talk to brokers already on each panel before signing, and revisit our comparison of leading aggregators when shortlisting.
Tools and online presence
Three tools earn their cost early: Customer Relationship Management software to track every lead and follow-up, Loan origination software to manage applications, and calculators that make serviceability conversations concrete. Keep an eye on artificial intelligence tools as they mature; several now automate document collection and status updates. Online, a simple professional website with your services, contact details and a short blog tracking mortgage trends beats an elaborate site left untouched, and one or two social platforms used consistently, such as LinkedIn or Instagram, beat dormant accounts everywhere.
Your launch checklist
Before writing your first file, confirm all five foundations: current qualification, authorisation in place, aggregator signed, twelve months of operating capital banked and compliance templates ready. Then set one measurable ninety-day goal, such as ten lodgements or three active referrer relationships, and review progress against it weekly. Businesses that launch on a measured sequence reach sustainability; businesses that improvise their way through the commission gap usually close before the trail arrives.
