This is one of the most common questions Australians ask when starting their home buying or refinancing journey. Both paths lead to a home loan — but they offer very different experiences and, often, very different financial outcomes.
The short answer: in the vast majority of cases, using a mortgage broker saves you money and time. Here's why.
How the Bank Model Works
When you go directly to a bank for a home loan, you're dealing with a lender who has one product suite: their own. A Commonwealth Bank employee can only offer you Commonwealth Bank products. A Westpac banker can only offer Westpac.
Within that constraint, they'll find the best match for your situation — but they're not comparing with NAB, ANZ, ING, Macquarie, Athena, or any of the dozens of competitive non-bank lenders. You're getting their best offer, not the market's best offer.
Banks also have standard policies and limited flexibility for borrowers who don't fit the template exactly — self-employed, variable income, complex structures, or unusual employment types.
How a Mortgage Broker Works
A mortgage broker is an intermediary who accesses multiple lenders on your behalf. NIK Finance, for example, compares over 40 lenders — including the major banks, regional banks, credit unions, and specialist non-bank lenders.
Our job is to understand your situation completely — your income, debts, goals, and preferences — and then identify the lender and product that best matches your needs. We handle the paperwork, communicate with the lender through the application, and advocate for you through the approval process.
We're paid a commission by the lender when your loan settles. This fee is disclosed in your credit contract. The commission structure means our service costs you nothing directly.
Rate Comparison: Broker vs Bank
In 2026, competition among Australian lenders is strong. Non-bank lenders in particular often offer significantly better rates than the major banks.
Example comparison on a $750,000 loan over 30 years:
| Lender Type | Rate (Example) | Monthly Repayment | Total Interest (30yr) | |-------------|---------------|-------------------|-----------------------| | Big 4 bank (standard variable) | 6.50% | $4,743 | $957,480 | | Credit union (competitive) | 5.95% | $4,476 | $860,360 | | Non-bank lender (Athena/loans.com.au type) | 5.69% | $4,348 | $815,280 |
Total saving over 30 years with broker-sourced loan vs standard bank rate: up to $142,000.
This is the most compelling argument for using a broker — access to the full market means access to rates and products that banks will never proactively offer their own customers.
Service Comparison: Broker vs Bank
| Factor | Direct Bank | Mortgage Broker | |--------|-------------|----------------| | Product choice | Single lender | 40+ lenders | | Rate availability | Standard or negotiated | Wholesale/market best | | Application support | Call centre or branch | Dedicated broker | | Self-employed assessment | Often restrictive | Specialist lenders available | | Credit issues | Often declined | Specialist lenders available | | Cost to you | $0 | $0 | | Time investment | High (multiple applications if declined) | Lower (one assessment, multiple options) |
When a Bank Might Be the Right Choice
There are scenarios where going direct to a bank makes sense:
-
Existing relationship: If you have a longstanding relationship with a bank, have all your accounts there, and they offer a competitive packaged rate (including offset, redraw, professional waiver), the bundle might genuinely be the best deal.
-
Simple, straightforward application: If you're a high-income PAYG employee with a large deposit, pristine credit, and a standard property — the major banks will want your business and may offer very competitive rates to retain you.
-
Speed is the absolute priority: Going direct to one lender can occasionally be faster if the broker's multi-lender assessment takes time. (Though NIK Finance typically provides assessment within 24 hours, comparable to or faster than branch banking.)
The Broker Obligation: Best Interest Duty
Since 2021, Australian mortgage brokers have been subject to a Best Interest Duty — a legal obligation to act in the client's best interest, not the lender's. This means brokers cannot simply recommend the lender that pays the highest commission — they must recommend the product that genuinely serves the client best.
This duty is enforced by ASIC and backed by real penalties. It means you can trust that a licensed broker's recommendation is made in your interest.
The Commission Question
Some people are uncomfortable with the commission model — the idea that a broker is paid by the lender might create a conflict of interest. This is worth addressing honestly.
The Best Interest Duty addresses this legally. Beyond that, practical reality: if a broker recommends a poor product and the client refinances away quickly (within 18 months, typically), the broker must repay their commission to the lender (called "clawback"). This means a broker has a real financial incentive to recommend a product the client will be happy with long-term.
Commission disclosure is a legal requirement in Australia. All commission amounts must be disclosed in writing before you commit.
A Broker Saves You Time Too
A home loan application involves significant documentation and communication. A broker manages this entire process:
- Pre-assessing your documentation before applying (avoiding surprises)
- Knowing which lender's policies best suit your situation
- Submitting the application in the right format for that lender
- Following up with the lender to push the assessment forward
- Communicating approval conditions and helping you satisfy them
- Coordinating settlement with your conveyancer/solicitor
This takes hours of work — work you don't have to do yourself.
Frequently Asked Questions
Does using a broker affect my credit score differently than applying direct? No. A broker submits a single application to the most appropriate lender, resulting in one credit enquiry. Going direct to multiple banks would result in multiple enquiries — worse for your credit score.
Can a broker help with an existing bank relationship? Yes. A broker can negotiate with your existing bank on your behalf or identify a competitor with better terms. Many clients use a broker to leverage a competing offer against their existing lender.
Is the broker commission negotiable? Commission rates are set by lenders (typically 0.55%–0.65% upfront + 0.15%–0.20% trail). They're not directly negotiable by the broker. The net-of-commission rate available through a broker is generally more competitive than a direct bank rate anyway.
Can a broker access the same government schemes as banks? Yes. Brokers are accredited through the NHFIC (National Housing Finance and Investment Corporation) to access First Home Guarantee and Family Home Guarantee scheme places.
What if my broker's recommendation doesn't work out? NIK Finance is a licensed credit representative. If you believe a recommendation wasn't in your best interest, you can complain to the Australian Financial Complaints Authority (AFCA), which provides free external dispute resolution.
