Choosing a mortgage broker is the single most leveraged decision you will make in your home buying process. A good broker will shave thousands of dollars off your interest bill over the life of the loan, get you pre-approved in 48 hours, steer you into the right government scheme, and calmly talk you through every missed payslip and weird bank transaction the lender flags. A bad broker will push you into a product that pays them the highest commission, disappear between emails, and leave you scrambling when a settlement date falls over.
The problem is that from the outside, both types look identical. Every broker website promises 30+ lenders, personalised service, and a best interest duty. Every Google listing shows five-star reviews. Everyone describes themselves as a "first home buyer specialist."
This guide gives you the actual filter — seven specific things to check before your first meeting, ten questions to ask in that meeting, six red flags that mean walk away, and an honest breakdown of how brokers get paid and what that means for your loan. By the end, you'll know how to tell a good broker from a mediocre one inside the first fifteen minutes of conversation.
If you're still deciding whether to use a broker at all rather than going direct to a bank, start with our guide to why 77% of Australians now use a mortgage broker — then come back here when you're ready to pick one.
Mortgage Broker vs Bank — What You Actually Get With Each
Before you choose a broker, it helps to understand exactly what you'd be giving up by going direct to a bank. The comparison isn't just "one lender versus many" — the structural differences run deeper than most borrowers realise.
A bank sells its own products. When you walk into a branch or apply through an app, the person you're dealing with is a salaried employee whose job is to sell you that bank's home loan. They have no legal duty to tell you another lender would be cheaper. They don't know, in real time, what the other 29 lenders on the market are currently approving. They can offer small rate discounts off their advertised rate, but those discounts are governed by internal pricing policies — not by what the broader market is doing.
A broker is your agent, not the lender's. A mortgage broker is an independent third party who is licensed and legally required to act in your best interest. Since 2021, the best interest duty (BID) has been a legally binding obligation under the National Consumer Credit Protection Act. If a broker recommends a product that isn't in your best interest, they are breaking the law and can lose their licence. Banks have no equivalent duty to their direct customers — they are selling their own products, and that's disclosed up front.
Brokers see live approval behaviour across the market. A good broker submits dozens of applications per month across multiple lenders and has a real-time view of which lenders are currently approving 95% loans, which ones have quietly tightened their servicing calculations, which ones are rejecting certain postcodes, and which ones are running unadvertised specials for first home buyers. Your bank knows only what their own system is approving today.
Brokers are incentivised to get you approved — but on the right product. Brokers get paid an upfront commission only when your loan actually settles. If the application falls over, they earn nothing. This sharply aligns their interests with yours: they want the application approved first time, with a product you won't refinance out of in six months (they also earn a trail commission for as long as you hold the loan, so they want you to keep it). Banks earn regardless — their loan officers are paid to process applications, not to make sure yours specifically funds.
The pricing difference is real, and measurable. Industry data consistently shows that borrowers who use a broker secure rates 0.10% to 0.40% lower than borrowers who apply directly, even at the same bank. On a $600,000 30-year loan, a 0.25% lower rate saves roughly $30,000 over the life of the loan. The reason is simple — brokers have pricing tools that quote every lender's current "sharp" rate, and they know how to escalate an application to a lender's pricing team to match or beat a competing offer.
The trade-off: brokers add a small layer of friction. You'll have one or two initial meetings, exchange documents through their platform, and wait a day or two for them to compare lenders. If you value speed over every other factor and have a very simple application, going direct to your own bank is faster. For almost every other borrower — especially first home buyers, the self-employed, guarantor applicants, and anyone using a government scheme — a broker is objectively the better path.
How to Choose a Mortgage Broker — 7 Things to Check Before You Meet
Before you commit to a first meeting, do fifteen minutes of homework. These seven checks will filter out 80% of mediocre brokers before you waste time on a kitchen-table conversation.
1. Licence and credentials. Every Australian mortgage broker must either hold an Australian Credit Licence (ACL) or operate as a credit representative under someone else's ACL. Check ASIC's Professional Registers (asic.gov.au) by searching their name or company. Confirm they're also a member of a peak industry body — the MFAA (Mortgage & Finance Association of Australia) or FBAA (Finance Brokers Association of Australia). Both bodies require continuing professional development, have disciplinary processes, and set ethics standards above the legal minimum. If a broker isn't a member of either, that's a red flag on its own.
2. Panel size and composition. A broker's "panel" is the list of lenders they're accredited to submit applications to. A good panel has 30+ lenders and covers the big four (CBA, Westpac, NAB, ANZ), the second tier (Macquarie, ING, Bankwest, Suncorp, Bank of Queensland), credit unions and mutuals (Bank Australia, Greater Bank, Teachers Mutual), and at least two specialist non-bank lenders (Pepper, Resimac, Liberty) for non-standard applications. Ask for the full list in writing before your first meeting. A broker with a panel of 12 lenders cannot compare the market in any meaningful way.
3. First home buyer experience. Not every broker handles first home buyers well. The government schemes move constantly — the Home Guarantee Scheme, stamp duty concessions by state, the First Home Super Saver Scheme, state-specific grants — and a broker who mostly writes investment loans can easily miss $30,000 in savings your eligibility unlocks. Ask how many first home buyer applications they submitted in the last quarter. A dedicated first home buyer specialist will quote a number in the dozens. Someone who pauses and then says "a few" is telling you everything you need to know.
4. Google reviews and trail history. Read at least 20 Google reviews, not just the five on their website. Look for recurring themes — responsiveness, clarity of communication, behaviour when things went wrong. Any broker with fewer than 30 Google reviews and more than one year in business hasn't served many clients (or isn't asking for reviews, which signals weak process discipline). Ask directly: "Can I speak to one of your past first home buyer clients?" A confident broker will connect you within a day.
5. Response time in the sales process. The way a broker treats you before they've won your business is the best preview of how they'll treat you after. If they take three days to return your first email, disappear for a weekend, or send a generic PDF instead of a personalised response, you've learned everything you need to know. Good brokers respond to initial enquiries within a few business hours.
6. Transparency about commissions. Every broker earns an upfront and trail commission from the lender. A good broker will volunteer this information before you ask, quote typical commission ranges (0.50% to 0.70% upfront, 0.15% to 0.20% trail), and explain that under the best interest duty they can't let commission differentials drive their recommendation. A broker who gets cagey when you ask how they're paid is either inexperienced or hiding something.
7. Technology and document handling. Ask how they collect your documents. A good broker uses a secure client portal (NextGen, ApplyOnline, or similar) that encrypts everything and gives you a status view of your application. A broker who asks you to email scanned payslips and bank statements to a generic Gmail address is mishandling your sensitive financial data and probably running a sloppy back-office too.
Do these seven checks in under an hour and you'll walk into your first meeting with the three or four brokers who actually deserve it.
10 Questions to Ask a Mortgage Broker in Your First Meeting
The first meeting with a broker should feel like interviewing a professional, not being sold to. Come with these ten questions written down. How a broker answers each one tells you more than any marketing copy ever will.
- "How many lenders are on your panel, and which ones?" You want a full list in writing. A confident broker will have a one-pager ready. Watch for hesitation, vague numbers ("dozens"), or a refusal to put it in writing.
- "What's my realistic borrowing capacity, not the maximum?" The bank's maximum borrowing capacity is often 20-30% above what you can comfortably afford. A good broker will quote two numbers: what lenders will approve, and what you can afford without lifestyle compromise. Check your own starting point with NestPath's borrowing power calculator before the meeting so you can sense-check their answer.
- "Which government grants and schemes am I eligible for?" They should rattle off the First Home Guarantee, Family Home Guarantee, Regional First Home Buyer Guarantee, First Home Owner Grant (state-specific), stamp duty concessions, and the First Home Super Saver Scheme without looking anything up. If they say "I'll need to check," that's a first home buyer specialist they are not.
- "What documents do I need to prepare?" The correct answer: 3 months of payslips, 3 months of bank statements (all accounts), tax returns or NOAs if self-employed, photo ID, rental ledger or tenancy agreement, a HECS/HELP statement from myGov, and a summary of all debts (credit cards, BNPL, car loans). A vague answer ("just send me what you have") is a sign of laziness.
- "How long will pre-approval take, and how long does it last?" Expect 1-3 business days for straightforward applications and up to 1-2 weeks for complex ones. Pre-approvals typically last 3-6 months. A broker who promises same-day pre-approval with a major bank is either cutting corners or misrepresenting what pre-approval actually means — see our guide to how pre-approval actually works.
- "What should I avoid doing between now and settlement?" The correct list: no new credit cards, no Afterpay or Zip applications, no large purchases, no job changes, no closing of long-held accounts, no changing your address on key documents. A broker who doesn't volunteer this warning is going to have a very awkward conversation with you later when the lender declines your loan at unconditional approval.
- "If my application is declined, what's your process?" Declines happen — the question is what the broker does about it. A good broker will explain that they'll review the lender's declined reason, adjust the application (deposit structure, loan amount, product), and re-submit to a different lender from the panel. Bad brokers either ghost you or blame the lender.
- "How often will you contact me during the application?" A good answer: weekly updates even if nothing has changed, and immediate contact if anything needs your attention. Radio silence between application and settlement is a classic broker failure mode.
- "Can you explain the difference between the fixed and variable options on your top recommendation?" This is a curveball that tests whether your broker can translate lender jargon into plain English. A competent broker will walk you through rate lock fees, break costs, offset offsets on fixed rates, and when each option makes sense. See our fixed vs variable guide to sense-check their answer.
- "How do you get paid, and how does that affect your recommendation?" The correct answer is direct: "The lender pays me an upfront commission of roughly 0.5-0.7% of the loan amount when it settles, plus a trail commission of roughly 0.15-0.2% a year while you hold the loan. Commissions vary slightly between lenders, but under my best interest duty I can't let that steer my recommendation, and I'll show you my rationale in writing." Any answer that's evasive, defensive, or "oh don't worry about that" is disqualifying.
If a broker answers all ten of these well, you've almost certainly found the right person. If they stumble on three or more, keep interviewing — there are 19,000 licensed brokers in Australia and you only need one.
How Mortgage Brokers Get Paid in Australia (2026)
Brokers are free to you, the borrower, but nothing is actually free — the money just comes from a different pocket. Understanding exactly how that works helps you spot conflicts of interest before they distort your recommendation.
Upfront commission. When your loan settles, the lender pays the broker an upfront commission of roughly 0.5% to 0.7% of the loan amount, net of any offset balance. On a $600,000 loan, that's $3,000 to $4,200. This is paid once, shortly after settlement. If the loan doesn't settle, the broker earns nothing from the entire application process — which can represent 20 to 40 hours of work.
Trail commission. The lender also pays the broker an ongoing trail commission of roughly 0.15% to 0.20% per year, for as long as you hold the loan. On the same $600,000 loan, that's $900 to $1,200 per year, declining as the loan balance falls. This is the broker's "ongoing service" fee — in exchange, they're expected to review your loan annually, flag better deals in the market, and help you refinance or restructure as your situation changes.
Clawback. If you refinance or repay the loan within 12 to 24 months of settlement, the lender claws back some or all of the upfront commission from the broker. This is why some brokers try to lock you into fixed-rate products with break costs — not because it's right for you, but because it reduces their clawback exposure. The best interest duty exists partly to prevent this, and a broker who pushes fixed rates without a clear reason specific to your situation is one to question hard.
Other fees — should be zero. A well-run broker business does not charge the borrower an application fee, a success fee, a broker fee, or a "complexity surcharge." Those fees exist in a minority of broker practices, almost always flagged in the Credit Guide and Credit Proposal documents the broker must give you by law. If any document mentions a fee you have to pay, ask why before signing. For most standard residential loans, the lender's commission is the broker's entire compensation and no fee to the borrower is justified.
Commission variation between lenders. Commissions vary by lender — typically within a narrow band of 0.50% to 0.70% upfront — but some lenders pay more, some less. Under the best interest duty, a broker must demonstrate that any lender differential did not drive the recommendation. The Credit Proposal document they give you before application lists the exact commission for the lender they're recommending, so you can check it against other lenders they considered.
Bottom line: the lender pays, you don't. But the commission structure is not irrelevant — it creates incentives (settle the loan, keep the loan alive, avoid clawback) that a good broker manages transparently and a bad broker lets quietly shape their recommendation. The 10 questions above are designed to surface this.
Red Flags — When to Walk Away From a Mortgage Broker
Most brokers are competent professionals. A small minority will cost you tens of thousands of dollars, months of delay, and the house you wanted to buy. These are the six red flags that should make you walk away even if the broker has five-star reviews and a nice office.
1. They try to charge you a fee. The lender pays the broker. Any fee the broker tries to charge you on top — application fee, success fee, "advice fee" — is a sign of a business that can't earn enough on commissions alone, usually because their volume is too low. Walk away.
2. They recommend a lender before seeing your documents. A broker who tells you "I'll get you with ANZ" in the first meeting, before they've seen your payslips, bank statements, or property in mind, is not acting in your best interest. They're following a script, a commission tier, or a referral relationship. A real broker collects your documents, runs your numbers across at least three or four lenders' servicing calculators, and then presents a recommendation with comparative rationale in writing.
3. They refuse to put the comparison in writing. Under the best interest duty, brokers must document their recommendation and the alternatives they considered. If a broker resists giving you a written Credit Proposal comparing at least 2-3 lenders and loan products, they are either non-compliant or hiding something. You have a legal right to this document.
4. They push you towards a fixed rate without a clear specific reason. Fixed rates suit some borrowers, not all. A broker who defaults to fixed rates without understanding your income stability, savings, and plans to hold the property is either managing their own clawback risk or following a commission-aligned script. A good broker explains trade-offs — see our comparison of fixed vs variable home loans — and defers to your preferences with reasoning.
5. They pressure you to sign quickly. A competent broker never needs urgency as a sales tool. "The rate's going up on Monday, we need to lock in today" is a tactic, not a fact — you can always lock a rate later, pay a rate-lock fee, or simply switch lenders if the market moves. A broker who creates artificial urgency is a broker you cannot trust with the biggest financial decision of your life.
6. They disparage other brokers or banks unprofessionally. Good brokers describe competitors in neutral, factual terms. "Bank X has slower turnaround times right now" is fine. "All brokers except me are idiots" is not. Unprofessional disparagement is usually a tell that the broker is covering for their own limitations.
If you spot any of these, politely end the meeting and move on. Good brokers are common — you don't need to put up with a bad one out of awkwardness or time pressure.
Do First Home Buyers Need a Mortgage Broker?
Short answer: almost always, yes. Longer answer: the more complex any part of your situation is, the more a broker pays for themselves many times over.
You need a broker if any of these apply to you:
- You have a small deposit (under 20%) and want to avoid LMI using the First Home Guarantee, Family Home Guarantee, or a guarantor loan.
- You're self-employed, a contractor, or have variable income (commissions, bonuses, multiple jobs). Different lenders treat these incomes completely differently.
- You have HECS/HELP debt, BNPL exposure, or credit card limits that might be hurting your borrowing capacity more than you realise.
- You're planning to use a government scheme — First Home Super Saver Scheme, state stamp duty concessions, First Home Owner Grant.
- You're buying in a regional or outer-metro postcode where some lenders restrict lending.
- You're buying an apartment or off-the-plan property — lenders have strict rules about small units, high-density buildings, and short-settlement off-the-plan contracts.
- You want an interest-only structure for a specific reason (investment, transition, bridging).
You can probably go direct to a bank if all of these apply:
- You have a 20%+ deposit in cash, all in your own savings (no gifts, no parental guarantee).
- Your income is a single PAYG salary from an employer you've been with for 2+ years.
- You have no HECS debt, no credit cards, no BNPL, no car loan.
- You're buying a standard 3+ bedroom house in a major metro postcode.
- You're not using any government scheme.
- You already have a private-banking relationship with a bank that gives you preferential rates.
Almost no first home buyer meets all six of the "go direct" criteria. The typical first home buyer is a PAYG employee with some HECS debt, under 20% deposit, looking at the First Home Guarantee, and wanting to buy an apartment or a modest house in a middle-ring suburb. For that person — which is most of our readers — a broker isn't optional.
The good news: the cost of using a broker is zero, and the time cost is maybe three hours of meetings and document gathering spread over a fortnight. The upside — a rate 0.10 to 0.40% lower, eligibility for a scheme you might otherwise have missed, approval on a postcode your bank wouldn't touch — often exceeds $20,000 in lifetime savings.

Frequently Asked Questions
How do I choose a mortgage broker in Australia?
Check licence (ASIC register), peak body membership (MFAA or FBAA), panel size (30+ lenders), number of first home buyer applications written last quarter, Google reviews (read 20+, not just website testimonials), pre-sale responsiveness, written transparency on commissions, and whether they use a secure document portal. Interview 2-3 brokers with the same 10 questions and compare answers. The right broker will answer clearly, document everything in writing, and never pressure you into a same-day decision.
What questions should I ask a mortgage broker at the first meeting?
Ten essentials: (1) panel size and which lenders, (2) realistic borrowing capacity not just maximum, (3) which government grants you qualify for, (4) documents you need to prepare, (5) pre-approval timeline and validity, (6) what to avoid between application and settlement, (7) process if declined, (8) how often they'll contact you, (9) fixed vs variable rationale for your recommendation, (10) how they're paid and how it affects their recommendation. A competent broker will answer all ten clearly and often volunteer some of them before you ask.
Do I need a mortgage broker as a first home buyer, or can I go direct to a bank?
Almost every first home buyer benefits from a broker. You only make sense going direct to a bank if you have a 20%+ deposit in your own savings, a stable PAYG income with a 2+ year tenure, zero HECS debt and zero BNPL/credit card exposure, aren't using a government scheme, and are buying a standard metro house. If any of those don't apply — and they rarely all do — a broker will access lenders, schemes and rates your bank cannot offer, all at no cost to you.
How much does a mortgage broker cost in Australia?
Nothing, in the vast majority of cases. The lender pays the broker an upfront commission of roughly 0.5-0.7% of the loan amount when the loan settles, plus a trail commission of 0.15-0.2% per year while you hold the loan. You pay zero fees directly. A small minority of brokers charge fees — for very complex commercial or specialist loans — and they must disclose any borrower fee in the Credit Guide and Credit Proposal before you sign. For a standard residential first home buyer loan, no borrower fee is justified.
What's the difference between a mortgage broker and a bank?
A bank is a lender — it sells its own home loan products through its employees. A broker is an independent agent licensed under an Australian Credit Licence who compares 30+ lenders on your behalf and is legally required under the Best Interest Duty to recommend a loan that suits your circumstances. Banks have no equivalent duty to their direct customers. Brokers also have real-time visibility of which lenders are currently approving certain applications — a bank only knows its own system.
How long does it take to get a home loan through a broker?
Pre-approval through a broker takes 1-3 business days for straightforward applications and 1-2 weeks for complex ones (self-employed, multiple income sources, low deposit with scheme). Pre-approval is valid for 3-6 months. Once you find a property, full (unconditional) approval usually takes 3-7 business days once contracts are signed, pending valuation. Settlement then occurs on the date in your contract, usually 30-60 days after exchange. Total elapsed time from first broker meeting to keys in hand is typically 2-4 months.
