Leading banks in Australia FY 2024, by assets

Who are the ‘’big four banks’’?

The banking industry in Australia is heavily concentrated on the “big four”, which refers to the four largest banks that hold more than 80 percent of all loans from mortgage borrowers. The largest four banks started emerging from the 1980s as the big banks started a series of acquisitions and mergers that propelled them to the forefront, while a growing number of mortgage loans in the early 2000s’ housing boom solidified their place in the market. Commonwealth Bank’s total assets have been consistently high over the past decade and was the largest among the big four.

Consumer perception of the “big four”

Despite the oligarchical nature of the market, consumers have shown a high level of satisfaction with the big four banks. This has allowed the big four to continue to expand their market share over the years without significant backlash from the public while maintaining the highest brand values in the financial market.
