The Reserve Bank of Australia (RBA) conducts an annual survey of bank fees in Australia.  It includes 15 institutions that represent around 90% of the Australian banking sector (by balance sheet size). The RBA’s figures show that, in 2020, income from bank fees amounted to $7.9 billion, with business banking fees accounting for two-thirds of banks’ overall fee income, so it’s fair to say that business bank fees are important in Australia.
