Key Highlights
- A mortgage broker compares home loans across 50 or more lenders simultaneously. A bank can only show you its own products
- Since 2021, mortgage brokers in Australia have been legally required to act in your best interests under the Best Interests Duty. This is a binding legal obligation, not a marketing claim
- Brokers handle the research, paperwork, lender negotiation, and application management. You submit documents once, not multiple times to multiple banks
- Brokers are particularly valuable in non-standard situations: self-employed income, bad credit history, low deposit, defence lending, or complex investment structures
- Going direct to your bank can make sense if you have a strong existing relationship, a simple application, and have already verified their rate is competitive
- An annual rate review from your broker keeps your loan competitive over time, not just at the point of settlement
- Stanford Financial has settled over $1 billion in loans across 50 plus lenders and holds national MFAA awards for diversified brokerage and newcomer of the year
Every year, hundreds of thousands of Australians face the same question when taking out a home loan: do I go directly to my bank, or do I use a mortgage broker?
For most of Australian banking history, the default answer was the bank. You had a relationship with them, you knew their branch, and the process felt straightforward. But the lending landscape has changed significantly over the past decade. There are now hundreds of home loan products across dozens of lenders, government schemes have become more complex, and a legal framework requiring brokers to act in your best interests has fundamentally changed the value proposition.
This guide sets out the genuine differences between the two approaches so you can make an informed decision, not a default one.
Stanford Financial has access to over 50 lenders and has settled more than $1 billion in home loans.

Broker vs bank: what you actually get from each
Bottom line: A broker gives you the same result as going to 50+ banks simultaneously, without the time, effort, or credit file impact of doing it yourself.
What Does a Mortgage Broker Actually Do?
A mortgage broker is a licensed credit professional who acts as an intermediary between you and lenders. Rather than representing a single bank, a broker works across a panel of lenders and is required to recommend the product that best suits your individual circumstances.
In practical terms, a broker:
- Assesses your financial position: income, expenses, debts, deposit, credit history, and employment structure
- Identifies which lenders are most likely to approve your application at the best available rate
- Compares loan products across their full lender panel, including rates, fees, features, and serviceability criteria
- Prepares and submits the application on your behalf, managing the documentation process
- Liaises with the lender throughout assessment and coordinates settlement
- Provides ongoing support after settlement, including annual rate reviews and future lending needs
Brokers are licensed under the National Consumer Credit Protection Act, are required to hold Australian Credit Licences (or be authorised representatives of ACL holders), and must comply with the responsible lending obligations that apply to all credit providers.
Access to 50 Plus Lenders vs One Bank’s Product Shelf
This is the most straightforward argument for using a broker and it is worth stating plainly: when you walk into a bank branch, you will be shown that bank’s products. The loan officer is an employee of the bank. Their job is to convert you into a customer of that bank, using that bank’s rates and products.
A mortgage broker with a panel of 50 or more lenders can compare:
- The major banks (CBA, Westpac, ANZ, NAB)
- Challenger banks and customer-owned institutions (ING, Macquarie, Bank of Queensland, Heritage)
- Specialist lenders for non-standard situations (Pepper Money, La Trobe Financial, Liberty Financial)
- Boutique lenders with niche product strengths not available through retail branches
The rate difference between the most and least competitive lenders on a given application can be significant. On a $600,000 loan with 25 years remaining, a 0.5% rate difference equates to approximately $160,000 in total interest over the life of the loan. The broker’s job is to find the best available position for your specific profile, not the best available product for an average customer.

Lender panel: one bank vs a broker's full panel
The same borrower, the same loan amount — different rate outcomes depending on who you ask
Direct to bank
You see one lender's rate. If a better deal exists elsewhere, you'll never know.
Through a broker
The full market is compared for you. The best rate for your situation is selected — not the easiest for the broker to write.
Best Interests Duty: Why Brokers Are Legally Required to Act in Your Favour
Since 1 January 2021, mortgage brokers in Australia have been subject to the Best Interests Duty under the National Consumer Credit Protection Act. This is not a code of conduct or an industry aspiration. It is a binding legal obligation.
Under Best Interests Duty, a broker must:
- Act in the best interests of the consumer when providing credit assistance
- Prioritise the interests of the consumer when there is a conflict of interest between the consumer’s interests and the broker’s own interests
- Not recommend a product that is not in the consumer’s best interests, even if it pays a higher commission
This obligation was introduced following the Royal Commission into Misconduct in the Banking, Superannuation and Financial Services Industry, which identified cases of poor consumer outcomes in the mortgage industry. The Best Interests Duty was specifically designed to address them.
Bank employees do not operate under the same Best Interests Duty. They have an obligation to act responsibly in providing credit, but they do not have a legal obligation to recommend a competitor’s product if it would better suit your circumstances.
Best Interests Duty does not mean brokers are infallible. It means that when recommending a loan, the broker’s recommendation must be defensible as being in your best interests based on your disclosed financial situation. If you believe a recommendation was not in your best interests, you have grounds to make a complaint through AFCA.

How mortgage brokers are paid and why it costs you nothing

Brokers Do the Heavy Lifting
Applying for a home loan involves assembling a significant amount of documentation, understanding each lender’s specific serviceability criteria, presenting your application in a way that maximises approval prospects, and managing the process through to settlement. Most borrowers underestimate the time and complexity involved until they attempt it themselves.
When you use a broker, you typically:
- Submit your documents once, to the broker, rather than separately to each lender you approach
- Avoid multiple credit enquiries on your credit file. Each direct application to a lender creates a credit enquiry. A broker identifies the right lender first and submits one application
- Have the application prepared to the lender’s specific requirements, reducing the risk of delays or declines due to presentation issues
- Receive proactive updates from the broker throughout the assessment process rather than chasing the lender yourself
- Have settlement coordinated between the lender, your conveyancer, and any other parties without managing those relationships yourself
For buyers who are time-poor, unfamiliar with lending criteria, or dealing with a complex financial situation, the administrative value of a broker is often as significant as the rate outcome.

The real cost of paying 0.5% more than necessary
Extra interest paid over 30 years at different loan sizes · P&I · rate difference = 0.5% p.a.
A broker finding you a rate that is 0.5% lower than your bank's offer saves between $47,000 and $85,000 in total interest over 30 years depending on your loan size. That is far more than any broker fee would typically cost.
Specialist Knowledge for Non-Standard Situations
Where a broker’s value is most pronounced is in applications that fall outside the standard employed-borrower profile that the major banks’ automated systems are optimised for.| Situation | Why it benefits from a broker |
| Self-employed | Income is assessed differently by different lenders. Some use the last two years of tax returns, others accept one year, and some specialist lenders use bank statements. A broker identifies the lender whose criteria best fits your income structure |
| Bad credit or defaults | Some lenders will not consider any application with a default on file. Others have specific policies for types, ages, and sizes of adverse credit. A broker knows which lenders offer the best outcome for your specific credit profile without triggering multiple declines |
| Low deposit | LMI premiums vary significantly between lenders. Some lenders have LMI waivers for specific professions. The First Home Guarantee must be applied through approved lenders. A broker navigates these options simultaneously |
| Investment lending | Lenders assess investment properties differently for serviceability. Some cap the number of investment properties, others have specific LVR restrictions. Portfolio investors need a broker who understands how lenders stack up |
| Construction loans | Progress payment structures, builder contract requirements, and valuation processes differ between lenders. An experienced broker reduces the risk of delays during the build |
Ongoing Support After Settlement
The relationship with a good mortgage broker does not end at settlement. The lending market changes constantly: interest rates move, lenders release new products, your own financial circumstances evolve, and what was the right loan at settlement may not be the right loan three years later.
A broker who earns trail commission has a financial incentive to maintain the relationship and keep your loan competitive. In practice, this means:
- Annual rate reviews to check whether your current rate is still competitive against the market
- Proactive contact when your fixed rate period is due to end, before you roll onto a potentially higher variable rate
- Refinancing assistance when a better option becomes available, handled by someone who already knows your full financial picture
- Access to the same broker for future lending needs: investment properties, renovation loans, vehicle finance
This ongoing relationship is structurally difficult for a bank branch to replicate. Bank staff change. Relationship managers move on. The broker has continuity of knowledge about your situation that compounds in value over time.

Frequently Asked Questions
Does using a mortgage broker affect my credit score?
A broker typically submits one application to the lender most likely to approve at the best rate. One credit enquiry appears on your file. If you applied directly to five banks yourself, five enquiries would appear. Multiple credit enquiries in a short period can reduce your score, so using a broker can actually protect your credit file compared to self-managing multiple applications.
Is a mortgage broker the same as a lender?
No. A broker is an intermediary. They do not lend you money. The lender (bank, credit union, or specialist lender) provides the actual loan. The broker finds the right lender and manages the application process on your behalf.
Can a broker get me a better rate than going direct to a bank?
Often, yes. Brokers submit volume to lenders and in many cases have access to rates that are not publicly advertised. They can also negotiate on your behalf using competitive offers from other lenders as leverage. The best available rate for your profile is not always the lowest advertised rate online.
What happens if I am not happy with my broker’s recommendation?
You are never obligated to proceed with a broker’s recommendation. Ask the broker to explain their reasoning in full, including why other options were not recommended. If you believe the recommendation was not in your best interests, you can make a complaint to AFCA (the Australian Financial Complaints Authority) at no cost.
How do I know if my broker is comparing all available options?
Ask your broker how many lenders are on their panel and request a written comparison of at least three to five options with the reasoning for the recommendation. A good broker will welcome this question. You can also check the broker’s Credit Licence number on ASIC’s Connect register.
