Australia’s Top 10 biggest banks

When choosing to deposit your savings or take out a home loan, you may well wonder about the size of the bank or lender you’re doing business with, and whether they are one of the major players in the field.

Each month, the Australian Prudential Regulation Authority (APRA) releases data on Australia’s authorised deposit-taking institutions (ADIs). This data includes information on which banks, building societies or credit unions are the biggest by the size of their lending to owner-occupiers and investors, as well as the size of deposits they hold.

Bear in mind that Australia is also home to a number of ‘non-bank’ lenders who aren’t ADIs and so won’t appear in the tables below. These institutions tend to be relatively small compared to Australia’s largest banks. They can lend money but aren’t allowed to offer their own bank accounts to customers.

What are the ‘big four banks’ in Australia?

Though the banking landscape in Australia is vast, there are four major players typically referred to as the ‘big four banks’ – these institutions are the Commonwealth Bank of Australia, National Australia Bank, Westpac Banking Corporation and the Australia and New Zealand Banking Group. If you’d like to know more about the major banks, Canstar has compared all four on customer satisfaction, along with a number of other banks, as part of its Most Satisfied Customers – Banking Awards.

As you will see from the lists below, the big four banks continue to dominate in the areas of home loan lending to investors and owner-occupiers, but Macquarie Bank continues to grow its presence in these areas and is now Australia’s fifth-largest bank in both categories, as well as in the category of most deposits held. Below are the top 10 biggest banks in Australia in the areas of owner-occupier and investor lending, as well as total deposits held and size of credit card lending per household, per APRA’s most recent September 2024 figures.
