Mortgage Broker vs Bank: Which is Better for Your Home Loan?

September 24, 2025 My Home Loan Calculator 8 min read

When it comes to securing a home loan in Australia, you have two main options: working directly with a bank or using a mortgage broker. Both approaches have their advantages and disadvantages, and the best choice depends on your individual circumstances, preferences, and financial situation. This comprehensive comparison will help you understand the differences and make an informed decision.

What is a Mortgage Broker?

A mortgage broker is a licensed professional who acts as an intermediary between borrowers and lenders. They work with multiple banks and non-bank lenders to find home loan products that match your specific needs and circumstances. Mortgage brokers are regulated by the Australian Securities and Investments Commission (ASIC) and must hold an Australian Credit Licence or be an authorised representative of a licensee.

How Mortgage Brokers Work

What is a Bank?

Banks are financial institutions that provide home loans directly to customers. In Australia, the major banks (Commonwealth Bank, Westpac, ANZ, and NAB) dominate the home loan market, but there are also many regional banks, credit unions, and non-bank lenders offering competitive products.
