How Australia's Banking System Works: A Plain-English Guide

By Roopon Team8 min read

The Structure of the Australian Banking System

Australia's banking system is a tiered structure with the Reserve Bank at the centre and several layers of regulated institutions serving consumers and businesses. Understanding this structure helps you make better decisions about where to hold money.

  • The Reserve Bank of Australia (RBA): Australia's central bank - sets monetary policy (the cash rate), issues currency, and provides banking services to the government. The RBA does not deal with retail customers - it is the banker to the banks
  • The Big Four banks: Commonwealth Bank (CBA), Westpac, ANZ, and NAB are authorised deposit-taking institutions (ADIs) accounting for approximately 75% of Australian household banking. Each is listed on the ASX and regulated by APRA
  • Regional and mutual banks: Bank of Queensland, Bendigo and Adelaide Bank, Suncorp Bank (now part of ANZ), and others offer full banking services. Mutual banks (People's Choice, Teachers Mutual, Heritage) are customer-owned - profits returned to members rather than shareholders
  • Credit unions and building societies: Smaller ADIs traditionally focused on specific communities (police, teachers, industry workers). Now largely regulated identically to banks and competing on similar products
  • Non-bank lenders: Companies like Pepper Money, Liberty Financial, and La Trobe Financial provide mortgages and loans but are not ADIs - they do not take deposits and are funded from wholesale markets. Not covered by the Financial Claims Scheme
  • Foreign banks: HSBC, Citibank (now NAB), ING, and others operate as foreign ADI branches in Australia - regulated by APRA and accessing the Australian payment system

How the RBA Cash Rate Affects Your Finances

The RBA's cash rate decision is the most widely reported economic event in Australia - but many people do not understand the mechanism through which it affects their mortgage, savings account, and the broader economy.

  • What the cash rate is: The cash rate is the interest rate at which banks lend overnight funds to each other in the interbank market. The RBA targets this rate through open market operations - buying and selling government bonds to influence the supply of money
  • How it flows to mortgages: When the RBA raises the cash rate, banks' funding costs increase - they pass this on (usually within days) by raising variable mortgage rates. The transmission is not automatic and not always 1-for-1, but it is swift
  • How it flows to savings accounts: Banks also raise savings and term deposit rates when the cash rate rises - but typically with a delay and often incompletely. The RBA's research shows savings rate increases lag and are smaller than mortgage rate increases - the 'sticky deposit' problem
  • How it affects inflation: Higher rates reduce consumer borrowing and spending, reducing demand pressure on prices. Lower rates stimulate borrowing and spending, supporting demand. The RBA's primary mandate is maintaining inflation in the 2–3% target band
  • The cash rate cycle: Rate cycles typically run 2–5 years - periods of rising rates followed by holding and then cutting. The 2022–2023 tightening cycle saw the cash rate rise from 0.10% to 4.35% - the fastest and largest increase in 30 years. Understanding cycles helps mortgage holders plan
  • RBA Board decisions: The RBA Board meets monthly (except January) to review the cash rate. Decisions are published at 2:30pm AEST on the meeting day - followed by a Statement on Monetary Policy and press conference. Markets price in expected rate moves via overnight index swap rates, which you can monitor via ASX RBA Rate Indicator

Banking Regulation: APRA, ASIC, and ACCC

Australia's financial system is regulated by three primary bodies with distinct mandates. Understanding who regulates what helps you know where to turn when things go wrong.

  • APRA (Australian Prudential Regulation Authority): Regulates banks, credit unions, building societies, insurance companies, and superannuation funds for financial soundness - ensuring they hold sufficient capital to withstand losses and remain solvent. APRA does not handle individual consumer complaints
  • ASIC (Australian Securities and Investments Commission): Regulates market conduct - how financial products are sold, disclosed, and advised upon. Responsible for enforcing the Corporations Act, Superannuation Industry Act conduct provisions, and financial adviser licensing. If a bank mis-sold you a product or gave you inappropriate advice, ASIC is the relevant regulator
  • ACCC (Australian Competition and Consumer Commission): Enforces competition law and consumer protection - including in banking. Investigates cartel behaviour, price-fixing, and unfair contract terms. Conducted significant reviews of banking sector pricing and home loan switching friction
  • AFCA (Australian Financial Complaints Authority): The external dispute resolution scheme for banking, insurance, super, and financial advice complaints. Free to consumers - banks must be AFCA members and comply with determinations up to $1 million. The first port of call when a bank complaint is unresolved internally
  • The Banking Code of Practice: The Australian Banking Association's voluntary code - binding on member banks - sets minimum service standards for things like account access, hardship arrangements, vulnerable customers, and fee transparency
  • Post-Royal Commission reforms: The 2019 Hayne Royal Commission into Misconduct in Banking, Superannuation and Financial Services produced 76 recommendations - most implemented through legislation - fundamentally changing how banks can sell financial products, pay staff, and handle hardship

The Financial Claims Scheme: Protecting Your Deposits

Australia's deposit protection scheme is one of the most important - and least understood - consumer protections in the financial system. Knowing how it works prevents unnecessary anxiety and helps with sensible deposit management.

  • What the Financial Claims Scheme (FCS) covers: Deposits held with APRA-regulated Australian ADIs (banks, credit unions, building societies) are protected up to $250,000 per account holder per ADI. If the institution fails, APRA activates the FCS and depositors are repaid within 7 days
  • Per ADI, not per account: The $250,000 limit applies to your total deposits at a single institution - not per account. Three savings accounts at the same bank totalling $300,000 are only $250,000 protected. Splitting deposits across different ADIs extends protection
  • Who is covered: Individual account holders, joint accounts (each holder's share up to $250,000), businesses, and trusts are all eligible. Superannuation funds, managed investment schemes, and similar entities are not eligible
  • Australia's banking sector is exceptionally stable: The Big Four banks consistently rank among the world's most stable - APRA's capital requirements exceed international Basel III minimums. The practical risk of a major Australian bank failure is extremely low, but the FCS exists as a backstop
  • Foreign bank branches vs subsidiaries: Deposits with foreign bank branches operating in Australia are NOT covered by the FCS - the home country's scheme applies (if any). Deposits with foreign banks incorporated as Australian subsidiaries (e.g., ING Bank Australia Ltd) ARE covered
  • Non-bank lenders have no FCS coverage: As noted above, non-ADI lenders do not take deposits and are not covered. Never 'deposit' money with a non-bank lender expecting FCS protection - these are loan relationships, not deposits

Getting the Most From Your Banking

Most Australians significantly overpay for banking services and earn less than they should on deposits. These strategies close the gap between what you are receiving and what is available.

  • High-interest savings accounts: The difference between a Big Four bank's standard savings rate and a competitive online bank (ING, Ubank, Macquarie, ME Bank) is often 1.5–2.5% - on $50,000, this is $750–$1,250 per year. Interest rates are searchable via RateCity and Canstar
  • Term deposits for defined timeframes: If you do not need access to funds for 3–12 months, term deposits lock in a rate - useful when rates are declining and you want to preserve the current rate for longer
  • Negotiating fees and rates: Banks routinely waive account fees for customers who ask - particularly longstanding clients. Monthly fees of $5–$10 add up to $60–$120 per year for no service benefit. Call and ask for a fee waiver
  • Mortgage rate negotiation: Existing variable rate mortgage holders should call the retention team annually with a competing offer - many will match or approach the advertised new-customer rate. The 'loyalty tax' on mortgages averages 0.3–0.8% for existing customers vs new borrowers
  • Banking app features: Most major banks now offer split savings goals, spending categorisation, round-up investing, and automatic savings transfers - features that improve financial behaviour without additional products or fees
  • International transfer fees: Banks charge 2–4% on international transfers via exchange rate margins. Specialist providers (Wise, OFX, Airwallex) typically charge 0.3–0.5% for the same transaction - saving hundreds on significant transfers
