Is a Mortgage Broker Worth It in Australia? The Legal Duty Banks Don’t Owe You, The 100+ Lenders They Can’t Access, And Why It Costs You Nothing (2026)

The market has already voted, 81% of new home loans go through a broker

Before the legal argument, the commercial argument, or the values argument, the market data is worth sitting with for a moment.

According to the MFAA Quarterly Market Share Report for the March 2026 quarter, Australian mortgage brokers facilitated 81.0% of all new residential home loan settlements, the highest broker market share ever recorded. Eight years ago, in March 2018, that figure was 55.3%. Broker market share has grown 25.7 percentage points in eight years.

That’s not an incremental shift. That’s a structural change in how Australians finance the largest purchase of their lives. Four in every five new home loans in Australia in the March 2026 quarter went through a broker, not a bank branch. The volume attached to that share was $124.88 billion in new home loan settlements, the highest Q1 volume on record.

Two useful ways to interpret that data:

• If mortgage brokers were a poor deal for Australian borrowers, the market share trajectory would have flattened, plateaued, or reversed as consumers learned. It hasn’t. It has grown for 54 consecutive quarters of Cotality-compiled MFAA data since 2013.
• If mortgage brokers were purely a rate-comparison service, the growth of comparison websites and direct-to-lender digital tools would have absorbed most of the demand. That hasn’t happened either. What has happened is that borrowers with any degree of complexity, self-employed, non-vanilla income, deposits under 20%, refinances with strategy, investment portfolios, have moved decisively toward brokers.

The MFAA has argued in its parliamentary submissions that broker channel competition has driven bank net interest margins down over the past several years, saving the average homeowner a meaningful annual sum on mortgage repayments. The specific dollar impact is debated, but the direction of the pressure is not.

None of that answers the individual question, “is a broker worth it for me?”, but it frames it. The market has already voted. The rest of this piece explains why.

The legal duty banks don’t owe you

On 1 January 2021, a new legal obligation came into force for Australian mortgage brokers. It’s called the Best Interests Duty, and it’s the single most important thing to understand when comparing a broker to going direct to a bank.

What is Best Interests Duty, and when did it come into force?

The legal basis is in Part 3-5A of the National Consumer Credit Protection Act 2009, sections 158LA and following. According to ASIC Regulatory Guide 273, the obligation was introduced by the Financial Sector Reform (Hayne Royal Commission Response, Protecting Consumers) Act 2020, following Recommendation 1.2 of the Hayne Royal Commission into Misconduct in the Banking, Superannuation and Financial Services Industry. Compliance is assessed by ASIC under RG 273.

The obligation, in plain language: when a mortgage broker provides credit assistance to a consumer, the broker must act in the consumer’s best interests. Where a conflict of interest exists between the broker and the consumer, the consumer’s interests must be prioritised, this is the “conflict priority rule” in section 158T of the same Act.

What does the duty require in practice?

Three features of that duty matter in practice:

• Cost should generally be prioritised in the broker’s assessment of what’s in the consumer’s best interests. ASIC has said failing to investigate the lowest-cost options available may suggest non-compliance. Cost isn’t the only factor, features, structure, and speed can outweigh cost in specific circumstances, but the broker has to have considered cost seriously.
• Brokers cannot contract out of the duty through any notice or disclosure they ask the consumer to sign. Section 158T contains an anti-avoidance provision, attempting to procure the consumer’s consent to bypass the duty is itself a breach.
• There’s no safe harbour. Unlike the Best Interests Duty for financial advisers under Future of Financial Advice reforms, there’s no prescribed set of steps that a mortgage broker can complete to automatically satisfy BID. The broker’s conduct is assessed against the substantive standard of acting in the consumer’s best interests.

Does Best Interests Duty apply to bank staff?

No. Bank staff providing credit assistance from their own bank’s product range are not subject to the Best Interests Duty. That’s not an opinion, it’s a factual regulatory distinction. The Best Interests Duty in Part 3-5A of the National Credit Act applies specifically to mortgage brokers as defined in section 15B: persons who provide credit assistance in relation to credit contracts offered by more than one credit provider.

A bank employee providing credit assistance for their own bank’s home loan doesn’t meet that definition. What they owe you is the responsible lending obligation under RG 209 (the loan must be “not unsuitable” for you) and general obligations under Australian Consumer Law. What they don’t owe you is a legal test that says the product they’ve offered is in your best interests compared to the alternatives available in the market. Because they don’t sell the alternatives.

The practical effect: a bank staff member can present the bank’s product to you compliantly even if a materially better product exists elsewhere. A broker cannot, under BID, the broker must consider whether the recommendation genuinely serves the consumer’s best interests among the options available to the broker’s panel.

That is the single largest structural difference between the two channels. It’s not marketing. It’s federal law.

Broker vs bank: the differences at a glance

Before going deeper into the lender pool and cost mechanics, here’s the summary, the six structural differences between using a mortgage broker and going direct to a bank branch, in one view.

The table understates the practical differences in one area: policy fit. Rate is one variable, the lender whose credit policy accommodates your profile is often more important. The next section covers why.

100+ lenders versus one product menu

According to MFAA submissions to the parliamentary inquiry into the financial regulatory framework and home ownership, the Australian mortgage market has over 100 lenders offering home loans. That includes major banks, non-major banks, credit unions, mutual banks, non-bank lenders, specialist lenders, and white-label products written by aggregators.

An established mortgage broker’s accessible panel typically covers a substantial slice of that lender universe, often 30 to 60+ lenders directly, with visibility across the broader market through their aggregator relationships. Intellect Finance operates across a panel of over 100 lenders, covering home loans, commercial loans and asset finance.

A bank branch, by contrast, can offer exactly one bank’s products.

That’s the raw arithmetic. The reason it matters isn’t just rate, it’s policy fit. Different lenders write different profiles. A borrower who’s been knocked back at one bank isn’t a bad borrower; often they’re just at a bank whose credit policy doesn’t fit their profile. Move the same borrower to a lender whose policy is more accommodating to their income structure, deposit position, or credit history, and the file approves cleanly.

Where the differential really matters:

• Self-employed and complex income. Lender policies on how self-employed income is assessed vary widely. Some average two years, some take the lower of two years, some allow the latest year, some accept accountant declarations. The right lender for a self-employed borrower is often invisible from a single bank’s product menu.
• Deposits under 20%. LMI-avoidance policies for professional occupations, guarantor structures, government schemes eligibility. Different lenders participate in different combinations, at different LVR thresholds.
• First home buyer scheme applications. Only certain lenders participate in each government scheme. Getting the scheme right is a matter of matching the borrower to a participating lender with a fitting product.
• Refinancing with debt consolidation or equity release. The lender that gave you the cleanest home loan approval isn’t always the lender that treats your refinance with credit-card and personal-loan consolidation cleanly.
• Investment property portfolios. Lenders vary substantially in how they treat multi-property borrowers, some cap exposure, some cap total lending, some apply portfolio interest-rate stress tests differently. Matching your growth trajectory to a lender that supports it matters.
• Previous credit issues or knockbacks. Specialist lenders exist for borrowers with previous knockbacks, credit defaults, or non-standard employment histories. These lenders are almost never visible to a consumer directly.

Rate is one variable among several. For most borrowers with any degree of complexity, policy fit and structure matter as much or more. The lender that fits your profile is the lender that approves your file cleanly, at competitive terms, without frustrating conditions. Finding that lender is the work.

What a broker costs you (nothing, and why that’s not a catch)

How do mortgage brokers get paid?

Australian mortgage brokers are typically paid by the lender the borrower takes the loan with, not by the borrower directly. There is no service fee, no upfront charge, no application fee, no ongoing management fee paid by the borrower to the broker.

The broker receives:

• An upfront commission from the lender when the loan settles, a percentage of the loan amount.
• An ongoing trail commission from the lender for the life of the loan, a smaller percentage of the outstanding balance, paid monthly.

Specific commission rates vary by lender and aggregator relationship, but the structure is standard across the industry and regulated by ASIC.

Doesn’t broker commission create a conflict of interest?

The natural question: doesn’t that create a conflict of interest? The regulatory framework was designed to manage exactly that.

• The Best Interests Duty and conflict priority rule legally prevent a broker from recommending a product that entitles them to higher remuneration unless doing so is also in the client’s best interests. Recommending a higher-commission product when a lower-commission product would serve the client better is a breach of Part 3-5A of the National Credit Act.
• Commissions must be disclosed to the borrower in the Credit Guide before the broker starts providing credit assistance. That disclosure is required under the National Consumer Credit Protection Regulations. If you’ve engaged a broker and haven’t received a Credit Guide, that’s a compliance issue with the broker, not with the framework.
• ASIC monitors broker recommendation patterns across the industry and can identify brokers whose recommendations skew toward higher-commission products in a way inconsistent with BID.

Worth noting the comparison: bank staff providing credit assistance also receive incentives, performance bonuses, internal KPIs, product-of-the-month targets. Those incentives are typically less disclosed to consumers than broker commissions are. A bank staff member isn’t required to give you a Credit Guide disclosing their commission structure before advising you, because the disclosure framework in the National Credit Act sits differently for a bank’s own credit provider representatives than it does for third-party mortgage brokers.

Which is to say: neither channel is free of incentive structures. The broker’s incentive structure is disclosed and regulated under a duty that prioritises the consumer’s interests. The bank staff’s is less disclosed and doesn’t include a comparable duty. Reasonable people can decide how to weigh that. Most borrowers, once they understand it, weigh it toward the broker.

When a broker matters most

The scenarios where broker value is highest are the scenarios where the specific lender that fits your profile is not obvious from a single bank’s product menu, where finding the right lender is genuinely the work.

• Non-vanilla income. Self-employed, contractor, commission-based, bonus-heavy, multiple income sources, foreign income, trust distributions, rental income across a portfolio. Lender policies vary sharply on how each type is assessed.
• Deposit under 20%. LMI position, professional-occupation LMI waivers, government scheme eligibility, guarantor structures, all involve navigating specific lender policies and specific scheme lender participation.
• Refinancing with a strategy attached. Debt consolidation, equity release for investment, structural changes to your borrowing across owner-occupied and investment.
• Investment property portfolios. Lender exposure caps, portfolio-level assessment, rental income treatment, negative gearing considerations.
• Guarantor loans. Parental guarantor, family pledge, security guarantee structures, lender policy varies significantly here.
• Construction loans. Progress payment structure, lender panel-of-valuers, construction-specific product features. Not every lender writes construction loans well.
• First home buyer scheme applications. Australian Government 5% Deposit Scheme (renamed from First Home Guarantee 1 October 2025), FHSS, state first home buyer concessions, participating lender lists vary.
• Previous knockbacks or credit issues. Specialist lenders exist for borrowers with prior defaults, non-standard employment history, or previous mortgage stress.
• Time-pressured settlements. Fast approval requirements where the lender pool is heavily skewed toward specific fast-settlement lenders.

In each of these scenarios, the broker’s value isn’t just comparing rates, it’s identifying which lender’s policy accommodates the specific complexity in the file, and structuring the application to that lender’s requirements.

When a broker isn’t the right answer

The counter-case worth stating openly, because the piece isn’t a sales pitch and because Best Interests Duty itself works both ways.

Scenarios where a broker’s added value is smaller:

• Very simple profile at your existing bank with a small top-up. If you have a straightforward PAYG income, a clean credit file, an existing home loan at your current bank, and you want to increase the facility for a renovation or minor purchase, the direct-to-bank path is fast and clean. A broker will often confirm that path is the right one at no cost to you.
• Borrowers with a private banker relationship already delivering. If you sit with a private banker who’s structured your borrowings competitively, understands your family situation, and is delivering meaningful ongoing service, the marginal value of moving to a broker is limited. The relationship is often the point.
• Very short-term borrowing where speed matters more than optimisation. Occasionally the direct-to-bank timeline beats the broker-managed timeline by just enough to matter. Rare but real.
• Ideological preference against non-bank lenders. Some borrowers strongly prefer to bank with a specific major bank for reasons beyond financial optimisation. Those preferences are legitimate, and a broker’s panel doesn’t add value if the borrower has effectively pre-selected the lender.

In each of those scenarios, an honest broker’s role, under BID, is to confirm the direct path is right and to charge nothing for that conversation. That’s part of what the duty legally requires.

The reason for including this section is straightforward: if a piece can’t honestly describe when its service isn’t the answer, the piece isn’t credible when it describes when it is. Best Interests Duty is a two-way street. So is genuine advice.

What actually makes a broker good at their job

Not all brokers are equal. The differences that matter when choosing one:

• Experience across cycles. A broker who has only worked through low-rate stable conditions has fewer patterns to draw on than one who has structured deals through multiple rate cycles, credit-cycle tightening periods, and property-cycle shifts. Pattern recognition is what most of the work actually is.
• Full-of-market lender access. Some brokers work off narrow lender panels, 20 or fewer lenders. Some work off broad panels of 50+ or 100+. The wider the panel, the more likely the right lender for your specific profile is on it.
• Genuine independence. Not every broker is equally independent. Franchise-model brokers, lender-owned aggregators, and brokers with specific referral arrangements can operate perfectly ethically under BID, but structural independence still matters at the margin.
• Ability to fight for the file after lodgement. The best brokers don’t just lodge, they escalate, negotiate, and push back when lender assessors ask for unnecessary conditions or slow the file. That capability is what separates a competent broker from an outstanding one.
• Relationship stability across your next moves. The best broker relationships span years, same broker for your first home, refinance, investment property, family home upgrade. That continuity means the broker knows your file, remembers what worked, and starts the next conversation with 60% of the context already loaded.

Rate matters. Panel matters. But over a decade of borrowing decisions, the broker’s judgment and continuity matter more than any single rate decision.

The Intellect Finance approach, family-run, not a call centre

A closing note on how Intellect Finance operates, because the family-business model isn’t universal in the broker channel and it materially shapes how the work gets done.

The business is family-run. Joe Sukkar is the principal broker, holding ACL 390611 since 2005. Family members work in the business, spouse, children, nephew. The specialists are Moufid (Head of Residential, Western Sydney corridor), Charbel (commercial, SMSF, complex income and specialist applications), and Chantelle (asset and personal finance). That’s the whole team. There’s no call centre. There’s no offshore application-handling desk. There’s no rotating pool of relationship managers.

What that looks like in practice:

• The person who takes your first call is the person who lodges your file, negotiates with the lender, sees the file through to settlement, and picks up your call three years later when you’re refinancing.
• Your file details are held by the same team over time. Your income structure, your family situation, your borrowing history at Intellect Finance, all of it sits with the broker who’s known you, not a name in a CRM.
• Clients are treated as long-term relationships, not transactions. The “part of the family” claim isn’t marketing; it manifests operationally in returning clients across their next home, their kids’ first homes, their investment portfolios, their commercial ventures.

Over 25 years, this model has produced 6,565+ settlements and 112 five-star Google reviews. The model isn’t better than every other broker model in every scenario, but for borrowers who value knowing who they’re talking to and having that person stay the same across the next decade of their financial life, it’s a different proposition to the call-centre model that dominates parts of the industry.

That’s the case. Legally, commercially, honestly. Read the counter-case above too, and decide what fits your situation.
