Mortgage Broker vs Bank in Australia: 4 Real Differences
I'm a mortgage broker. So before you read another word, you should know I'm probably biased.
But I also spent over a decade inside Australia's major banks before founding Everstone Finance. I've sat on both sides of the desk. I've seen exactly how banks decide what to offer you, what they don't tell you, and why so many Australians end up paying more than they need to on the biggest financial commitment of their lives.
This article isn't about convincing you brokers are saints or that banks are villains. Both have their place. But if you're trying to decide whether to walk into your bank or sit down with a mortgage broker in Australia, here's what I think you actually need to know.
In short: a bank can only offer its own home loans, while a mortgage broker compares loans across many lenders and arranges the one that suits you. A broker is paid by the lender after settlement, so the advice is free, the rate is no higher than going direct, and you get wider choice plus someone who keeps reviewing your loan over time, not just at sign-up.
Usually yes. A mortgage broker compares many lenders at once, while a bank only offers its own loans. In Australia brokers settle most new home loans and are bound by a Best Interests Duty to put you first. A bank branch carries no such duty and shows you a single product range.
Broker vs bank at a glance
Our verdict up front: a broker compares 40+ lenders and is legally bound by the Best Interests Duty, while your bank can only sell you its own products. Going direct still makes sense in a few specific cases, and I cover those further down.
| Going direct to a bank | Using a mortgage broker | |
|---|---|---|
| Loan options | One lender's own products | 30 to 40+ lenders compared, including non-banks |
| Cost to you | Free | Free, the broker is paid by the lender after settlement |
| Legal duty to you | No general duty to find you the best deal | Best Interests Duty: legally required to act in your interest |
| Rate over time | Reactive, you have to notice and ask | Proactive reviews, your broker re-checks your rate for you |
| Complex income | One credit policy; doesn't fit, declined | Matched to the lender whose policy suits your situation |
| Paperwork | You manage the application | Broker manages it from application to settlement |
Context for the table: roughly three in four new Australian home loans are now arranged through brokers, a record high (MFAA industry data, 2025). And staying put has a measurable cost, the ACCC's Home Loan Price Inquiry found borrowers with loans more than three years old were paying around 0.58 percentage points above the rate offered to new customers.
What is a mortgage broker, and how do they get paid?
A mortgage broker is an independent professional licensed under an Australian Credit Licence (ACL) who compares home loans across a panel of lenders on your behalf. Instead of being employed by one bank to sell that bank's products, a broker works for you, and gets paid by the lender once your loan settles.
That last part trips people up, so let's be clear: using a mortgage broker in Australia costs you nothing. The lender pays the broker an upfront commission (usually 0.6 to 0.7% of the loan amount) plus a small trail commission over time. These commissions are baked into the loan and are virtually identical across the major lenders, which means an independent broker has no financial incentive to push you toward one bank over another.
In contrast, a bank lending officer is employed directly by that bank. Their job is to sell that bank's products. They legally cannot offer you a competitor's product, even if it's cheaper.
The key difference: A bank staff member is held to a "not unsuitable" standard. A broker, under ASIC's Best Interests Duty (introduced 2021), is legally required to act in your best interests. That's a structurally different relationship.
Broker or bank: which should you use?
After years inside major banks and years now on the other side as an independent broker, here's what I've learned actually moves the needle for borrowers in Australia.
A bank shows you one rate. A broker shows you forty.
When you walk into a Big Four branch, the loan you'll be offered is the loan that bank sells. The lending officer might have two or three product tiers to choose from, usually a basic loan, a package loan, and maybe a fixed-rate option, but they're all that bank's products.
A mortgage broker in Australia typically has access to 30 to 40+ lenders, including the big banks, second-tier lenders, credit unions, and specialist non-bank lenders. That panel includes options most borrowers have never heard of, and many of those non-bank lenders consistently offer rates 0.3 to 0.6% below the big banks because they don't have the overhead of physical branches.
A bank waits for you to notice. A broker tells you first.
Banks don't proactively call you when a better rate becomes available. Why would they? They make more money from customers who don't shop around.
This is one of the most underrated benefits of using an independent broker. A good broker reviews your loan annually, sometimes more often if rates are moving, and contacts you when there's a meaningful saving available. That ongoing service is part of the trail commission a broker earns from the lender, which means it costs you nothing to have someone constantly checking whether you're still on a competitive rate.
Most Australian borrowers don't review their home loan for 4 to 7 years after settlement. In a market where rates have moved as much as they have in the past three years, that's the best time to refinance for most people, and they don't realise it.
Banks reward new customers, not existing ones. The "loyalty tax", the gap between the rate a new borrower gets versus an existing one on the same product, can be 0.5 to 1.0% or more. On a $700,000 loan that's $3,500, $7,000 in extra interest every year, paid by people who simply never asked for a review.
This isn't a broker talking point: the ACCC's Home Loan Price Inquiry documented the same pattern, with older loans priced well above the rates offered to new borrowers on the same products.
At a bank, you start over every time. With a broker, you don't.
If your local bank manager changes, and they will, you start the relationship from scratch. New person, new conversation, new explanation of your situation. Banks rotate staff constantly. The teller who knew you last year is in another branch now.
A broker is a single relationship that carries forward. The same broker who helped you with your first home loan can help you refinance five years later, structure your investment property purchase, run a debt recycling strategy across your portfolio, and review your overall position annually. There's no "let me pull up your file", they already know your goals, your history, and what's worked for you before.
For people who plan to use property as a wealth-building strategy across multiple loans and multiple years, this continuity is worth more than people realise. It compounds.
A bank fits you to their products. A broker fits products to you.
This is the difference that matters most for anyone whose situation isn't textbook.
If you're a PAYG employee with two payslips, a clean credit file, and a 20% deposit on an owner-occupied property in a major city, almost any bank will lend to you. You're easy. The rate will be close to whatever they advertise.
But if you're self-employed, on a complex income structure, buying through an SMSF, looking at an investment property, releasing equity for renovations, recently changed jobs, recovering from a credit hiccup, the bank's answer is often "no" or "yes, at a higher rate."
Where a broker earns their keep
- Self-employed borrowers: Some lenders assess income via BAS statements, accountant letters, or business bank statements rather than traditional payslips.
- Investment property loans: Different lenders have very different appetites and serviceability calculations for investors.
- SMSF property purchase: A niche structure most bank staff aren't even trained on. Specialist lenders handle this well.
- Equity release for renovation or investment: Some lenders allow this with minimal evidence, others require full reapplication.
- Complex income (bonuses, commissions, overseas): Lender policies vary wildly. The right lender can mean tens of thousands more in borrowing capacity.
A good broker matches your circumstances to the lender most likely to say yes at the best rate, not to the only lender they happen to work for.
Are mortgage brokers really free?
Yes, for the vast majority of residential home loans in Australia.
The lender pays the broker a commission once your loan settles. This commission is funded out of the lender's marketing and customer acquisition budget, it costs them less to pay a broker who delivers a qualified, ready-to-settle borrower than it does to run TV ads, staff branches, and employ in-house lenders to chase the same customer.
The three things to know
- Commission rates are standardised, roughly 0.65% upfront plus 0.15% trail across most major lenders. A broker can't earn dramatically more by steering you to one lender over another.
- The commission doesn't change your rate, the rate you'd get directly from the bank is the same rate (or worse, many brokers can access broker-only discounts unavailable to walk-in customers).
- The broker must disclose all commissions, under ASIC's Best Interests Duty, every Australian mortgage broker is legally required to act in your best interests and disclose exactly what they'll be paid.
When does going direct to the bank actually make sense?
To be fair, there are situations where going direct works:
- You already bank with them and want a simple top-up loan on existing equity. Sometimes the friction of changing lenders isn't worth a small rate difference.
- Your situation is textbook simple and you've already shopped the market yourself.
- You qualify for a private banking tier with a major lender, where rates and structures can sometimes match or beat the broker market.
Outside those scenarios, the case for at least talking to a broker before signing with a bank is overwhelming. You're not committing to anything by getting a comparison, and the comparison itself usually pays for the time it took.
How to choose a good mortgage broker in Australia
Not every broker is good. Independent broker benefits only stack up if the broker is actually independent and actually competent. A few things to look for:
- An Australian Credit Licence or Credit Representative number, every legitimate broker has one. Cross-check it on ASIC's register at moneysmart.gov.au.
- Membership of MFAA or FBAA, the two industry bodies set professional standards above ASIC's minimum.
- Lender panel size, a panel of 30+ lenders is the broad minimum.
- Independent, not aligned, some brokers are owned by or aligned with a single lender. Ask directly: "Are you owned by a bank or aligned with any specific lender?"
- Reviews from real clients, Google reviews are harder to fake than testimonials on a broker's own website.
- Bilingual or culturally aligned if you need it, important documents are easier to understand when explained in the language you think in.
The honest summary
Banks aren't bad. They're businesses, and their business model is selling their own products to as many people as possible. A bank lending officer can be perfectly competent and still completely unable to offer you the best loan in the market, because the best loan in the market often isn't theirs.
A mortgage broker, when independent and operating under the Best Interests Duty, has structural alignment with your goals: they get paid when you settle, the commission is roughly the same regardless of which lender you choose, and they're legally obligated to recommend what's best for you.
The bottom line: It costs you nothing to find out where you stand. Lenders pay our fees. You don't. That's the whole pitch.
We work with banks. We don't work for them.
If you're considering a refinance, buying your first home, structuring an investment property, or just want a second opinion on your current loan, a quick conversation costs you nothing and could save you tens of thousands.
What a quick call covers
- Whether your current rate is still competitive in today's market.
- How much you could borrow on your current income and situation.
- Which lenders are best suited to your specific circumstances.
- Whether refinancing now makes sense or whether timing matters.
- What documents you'd need to move forward if you wanted to.
No obligation, no credit check, no pressure to proceed. If we can help, we will. If your current lender is already competitive, we'll tell you that too.
Broker vs bank: your questions answered
Are mortgage brokers free in Australia?
Yes, for the vast majority of residential home loans. The lender pays the broker an upfront and trail commission. You pay nothing for the broker's service. Commission rates are standardised across major lenders at roughly 0.65% upfront plus 0.15% trail, so a broker has no financial incentive to steer you toward one lender over another.
Is it better to use a mortgage broker or go to the bank directly?
For most people, a broker offers more choice (30 to 40 plus lenders versus one), more ongoing service (annual reviews versus none), and structural alignment with your interests under ASIC's Best Interests Duty. Going direct to the bank makes sense in a few specific cases such as existing customer top-ups, private banking tier clients, or borrowers who have thoroughly shopped the market themselves.
Do mortgage brokers get better rates than banks?
Often yes, for two reasons: brokers can access broker-only discounts not offered to walk-in bank customers, and the broker can compare across 30 to 40 lenders to find the most competitive option for your specific situation, which the bank cannot do.
How does a mortgage broker work?
A broker reviews your financial situation, assesses what loan products you would qualify for across their lender panel, recommends the best fit, prepares the application, manages the lender relationship through to settlement, and reviews your loan annually thereafter.
