Types of commercial banks

The National Australia Bank (NAB), Commonwealth Bank of Australia (CBA), Australia and New Zealand Banking Group Limited (ANZ) and Wespac are the big four banks that dominate the Australian market. But there are other types of commercial banks in Australia, as explained below:

  • Community: These are financial institutions that operate locally throughout Australia. Customers or community members own these banks.

  • Regional: These banks are larger than community banks, but still operate below the state level. They offer their services in a limited area of a country.

  • Foreign: These are banks established outside Australian borders, such as Citigroup Bank or Bank of China. Foreign banks conduct their operations through an Australian branch.

  • Building societies and credit unions: The owners of these banks can be members of the community or union. They control their operation democratically by involving every member in decision-making.

Functions of commercial bankers

The following are some functions of a commercial banker:

Accepting deposits

As a commercial banker, you can receive customers' deposits on behalf of the bank. This might involve giving customers information regarding savings options and types of deposits. For instance, you can explain to customers that savings deposits can attract interest. You may also explain the difference between fixed and current deposits for customers without banking knowledge.

Providing loans

As a banker, one of your responsibilities involves educating customers on the types of loans, terms and procedures. Commercial bankers may work in organisations offering lending services as loans. Bankers may therefore facilitate the processing of both short-term and long-term loans.

Acting as an agent

Commercial bankers act as agents to their customers in various ways. For instance:

  • collecting bills, drafts and cheques

  • making insurance, rent and loan payment

  • acting as intermediaries between customers and the stock market

  • working as an administrator or executor of the estate for a customer

  • ensuring tax compliance by preparing income tax and claiming a tax refund for their customers

Issuing traveller's cheques

As a commercial banker, you might issue a traveller's cheque to customers and print a new one if they misplace the original copy. A traveller's cheque is a medium of exchange you offer tourists or travellers as an alternative to hard currency. People travelling to foreign countries and other vacations can use this document to settle their bills. Tourists with travellers' cheques can travel overseas freely without carrying cash.

Issuing credit cards

Commercial bankers prepare and issue credit cards to their customers that might allow them to purchase items or access services on credit from certain retailers. Customers can withdraw money up to a specific limit daily from Automated Teller Machines (ATMs). Besides issuing credit cards, you might also cancel cards or putting them on probation when you suspect fraudulent activities.

Facilitating foreign trade financing

As a commercial banker, having expert knowledge of foreign markets can be vital when working with customers with international trade interests. This is because, as a representative of the bank, you may provide services such as advising customers on foreign markets, facilitating credit services and enabling customers to access foreign currencies.

Your other functions may include:

  • linking customers and lenders

  • marketing bank products to attract new clients

  • offering other services to customers such as branding, financial planning, development of products, and business marketing to grow their businesses

  • tailoring financial services for sectors such as aviation financing, real estate investment loans and car dealer services

Requirements for a commercial banker

The following are requirements for a commercial banker:

Bachelor's degree

A bachelor's degree in business or any other relevant degree can give you a competitive advantage when pursuing a career in the commercial banking industry. Consider selecting a bachelor's program with significant studies in banking, which can include a bachelor's degree in commerce, finance, accounting, economics and business. You might also consider supplementing your banking knowledge with legal knowledge to make commercial banks consider your application. For instance, a Bachelor of Finance/Law can make you more appealing to a recruiter.


If you are interested in commercial banking, but prefer not to get a bachelor's degree, you can consider a Certificate IV in Financial Services. This qualification can help you gain financial and administration skills useful in your commercial banking career. Completing a Certificate IV in Financial Services can give you a background to thrive in the commercial banking career, because it provides you with a nationally accredited qualification that recruiters might value. For instance, with a Certificate IV in Finance and Mortgage Broking, you may apply for a position in a commercial bank and work towards becoming a mortgage officer.
