A mortgage broker acts as an intermediary between you and potential lenders when you refinance your home loan in Australia. Brokers can access multiple lenders (often 20 to 40 or more), compare products on your behalf, handle paperwork, and negotiate rates, potentially saving you time and money. Most brokers are paid by the lender through upfront and trailing commissions, so their service is typically free to you, though you should confirm this before proceeding.

What a Mortgage Broker Does When You Refinance

When you approach a broker to refinance, they assess your financial position, including your income, expenses, existing loan balance, property value, and credit history. They use this information to search their panel of lenders for home loan products that match your needs, whether that is a lower interest rate, better features such as an offset account or redraw facility, or a switch from a fixed-rate to a variable-rate loan.

Brokers submit your application to the chosen lender, manage the documentation process (payslips, tax returns, bank statements, identification), and liaise with the lender on your behalf until settlement. This can save you considerable time compared with contacting multiple lenders individually and filling out separate applications (MoneySmart, 2024).

Access to a Wider Range of Lenders

A key advantage of using a broker is access to lenders you might not approach on your own. While you can compare the major banks directly, brokers often work with smaller banks, credit unions, non-bank lenders, and specialist lenders that may offer competitive rates or unique loan features. Some lenders only distribute their products through brokers, not directly to the public (Finder, 2024).

However, not all brokers have access to every lender in the Australian market. Each broker operates with a specific panel, so it is worth asking which lenders they work with and whether any major institutions are excluded.

Cost and Commission Structure

Most mortgage brokers in Australia do not charge the borrower a fee. Instead, they receive an upfront commission (typically 0.5 to 0.7 per cent of the loan amount) and an ongoing trailing commission (around 0.15 to 0.2 per cent per year) from the lender. This commission model means the broker’s service is generally free to you, but it also means the broker has a financial relationship with the lender (Canstar, 2024).

ASIC requires brokers to act in your best interests and disclose their commission arrangements upfront. Before engaging a broker, confirm whether they charge any fees, how they are paid, and whether they receive different commission rates from different lenders, as this can influence which products they recommend.

When a Broker Adds the Most Value

A broker is particularly useful if you have a complex financial situation, such as self-employment, multiple income sources, or a less-than-perfect credit history. Brokers understand each lender’s serviceability criteria and can direct you to lenders more likely to approve your application.

Brokers can also save time if you are refinancing while managing work or family commitments and prefer to delegate the comparison and application process. If you are comfortable comparing loans yourself using online tools and have a straightforward financial profile, you may choose to apply directly with a lender instead.

What to Do Next

If you decide to use a broker, seek recommendations from friends or family, or search for accredited brokers through industry bodies. Confirm the broker’s accreditation, ask about their lender panel, clarify their fee structure, and discuss your refinancing goals clearly. Compare the loan products they recommend using the comparison rate (which includes most fees and charges) and verify the terms, break costs if leaving a fixed-rate loan, and any cashback offers or ongoing fees.

Rates and lending criteria change frequently. Always confirm current rates, fees, eligibility, and features with the broker and lender before proceeding with any refinancing decision.
