When you walk into a bank to apply for a home loan, you're speaking to someone whose job is to place you into one of that bank's products. They have no incentive — and in many cases no ability — to tell you that a competitor's product is better suited to your needs. A mortgage broker, by contrast, has access to dozens or hundreds of products across a wide lender panel and is required by law to act in your best interest. The difference sounds obvious, but its impact on the loan you end up with — and the total cost of that loan over 30 years — can be substantial.
Access to the Whole Market, Not One Bank's Shelf
Australia has more than 100 active mortgage lenders including the major banks, regional banks, credit unions, building societies, and non-bank lenders. Each lender has different credit policies, rate structures, serviceability calculations, and product features. Some lenders are far more flexible than others for self-employed borrowers; some offer genuine offset accounts with no monthly fee; some have specific policies that allow higher LVR lending without LMI for certain professions. An MFAA-accredited broker with a broad lender panel can identify in a single conversation which lenders are best suited to your specific profile.
"Mortgage brokers now facilitate over 70% of all new home loan applications in Australia — and there's a clear reason for that."
Best Interest Duty: Your Legal Protection
Since 2021, Australian mortgage brokers have been legally required to comply with a Best Interest Duty under the National Consumer Credit Protection Act. This means a broker must act in your best interest when providing credit assistance — not in the interest of any particular lender. This is fundamentally different from a bank employee, who is a representative of a single lender with no legal obligation to recommend products outside their employer's range.
The Real Cost Difference
The difference between a well-priced loan and an average-priced loan on a $700,000 mortgage can easily be 0.4% to 0.7% per annum, depending on how hard you negotiate and which lenders you access. Over 30 years, that gap compounds significantly. On a $700,000 loan, a 0.5% rate reduction saves roughly $175 per month — or $63,000 over the life of the loan. Most GS Capital clients who come to us after dealing directly with a bank report annual savings of $3,000 to $5,000 after a structured rate review.
How Mortgage Brokers Are Paid
In Australia, mortgage brokers are paid an upfront commission and an ongoing trail commission by the lender on successful settlement. For residential loans, this means the broker's service is free to the borrower — there are no adviser fees, no application fees charged by the broker, and no obligation. The commission structures are standardised across lenders (approximately 0.6% upfront and 0.15% trail per annum) and must be disclosed to you in writing before you commit. Because commissions are broadly consistent across lenders, a broker has limited financial incentive to prefer one lender over another — and is legally obligated to act in your interest regardless.
Where Brokers Add the Most Value
- Self-employed borrowers who don't have straightforward PAYG income — brokers know which lenders accept specific Alt Doc income verification methods
- Property investors building a portfolio — structuring multiple loans across a panel optimally requires active lender policy knowledge
- Borrowers with credit impairment, prior defaults, or non-standard employment — specialist lenders exist who assess these cases on merit
- Foreign income earners — especially important for Melbourne and Sydney buyers with income from China, Southeast Asia, or the Middle East
- Buyers under time pressure — brokers manage the application and lender relationship, removing bottlenecks that slow bank-direct applications
Annual Loan Health Checks
A good broker doesn't disappear after settlement. The home loan market changes constantly — new lenders enter, cashback offers appear and expire, rates move, and your circumstances evolve. An annual loan health check from your broker ensures your current loan remains competitive and that your structure still suits your life stage. At GS Capital, loan health checks for existing clients are always free of charge.
