Why the Rate Is Not the Only Number That Matters
The advertised interest rate on a savings account is almost never the rate you will earn every month. Most Australian banks offer a higher "bonus" or "maximum" rate that is conditional — earned only when you meet a set of requirements in a given calendar month. Missing those requirements, even in a single month, typically means your money earns the lower "base" or "standard" rate instead.
That means the right first question is not "what rate do you offer?" but "what do I need to do to earn that rate each month, and what happens when I don't?" The answer to that question determines whether a product is practically suitable for your situation.
A person who makes one withdrawal per year will react very differently to a no-withdrawal condition than someone who maintains the account as an emergency fund — where the whole point is to make a withdrawal when needed. Understanding conditions before you open an account is considerably easier than understanding them after.
The Eight Banks: What to Research at Each
The following Australian banks and banking divisions are among the major providers of savings accounts in Australia. Visit each one's official public website and read the current Product Disclosure Statement before forming any view on their products.
ANZ (anz.com.au): Research what monthly conditions apply to bonus interest, whether there are account-keeping fees, and whether the base rate is competitive if you miss the bonus criteria.
Bendigo Bank (bendigobank.com.au): Consider whether a regional bank's branch network and service model suits your banking habits, and what the ongoing rate structure looks like after any introductory period.
Commonwealth Bank (commbank.com.au): Research any minimum monthly deposit or balance growth conditions, and whether a linked transaction account is required.
ING (ing.com.au): ING typically structures bonus interest around activity in a linked everyday account. Research what minimum number of card transactions or deposits is required each month to earn the bonus rate, and whether that aligns with how you spend.
Macquarie (macquarie.com.au): Check whether there is an introductory rate period, how long it lasts, and what the rate reverts to after it ends. Also check for any balance caps on the higher rate tier.
NAB (nab.com.au): Research what account fees apply, under what conditions those fees are waived, and whether the account allows unlimited withdrawals.
St.George (stgeorge.com.au) is A Division of Westpac Banking Corporation. Research what monthly deposit and growth conditions apply to their savings products, what happens to the rate if those conditions are not met in a particular month, and how the product relates to other Westpac group offerings you may already hold.
Westpac (westpac.com.au): Westpac offers several savings products. Research how the rate structure works across different balance amounts and age brackets, and what the conditions are for each product.
The Questions Worth Asking at Any Bank
Regardless of which bank you are researching, these are the questions that reveal how a savings account actually works, not just how it is marketed:
What is the base rate and what is the bonus rate? The base rate is what you earn if you do nothing. The bonus rate is what you earn if you meet the conditions. Understand both numbers.
What are the conditions for the bonus rate? Common conditions include: depositing a minimum amount each month (often $200–$1,000), not making any withdrawals, maintaining or growing your balance, or making a minimum number of card transactions on a linked account. Some accounts require all conditions; some require one.
What happens if I miss the conditions in a given month? Some accounts drop to the base rate for the entire month. Others allow a single missed month with lower penalties. Know this before you choose.
Are there fees? Monthly account-keeping fees, transaction fees, and withdrawal fees are all possible. On modest balances, a $5/month fee can significantly reduce the effective return.
What is the minimum opening deposit? Some accounts require a minimum balance to earn interest at all.
How is interest calculated and when is it credited? Most Australian savings accounts calculate interest daily on the closing balance and credit it monthly. Understand the calculation method if you plan to make regular deposits or withdrawals.
Where to Cross-Reference What You Find
After researching a bank's public website and Product Disclosure Statement, it is worth cross-referencing with ASIC's MoneySmart (moneysmart.gov.au), which provides independent, general guidance on savings account features and how to evaluate them.
The Australian Banking Association's plain-English explanations of banking products are available at ausbanking.org.au. The Financial Claims Scheme, which covers deposits up to $250,000 per person per authorised deposit-taking institution (ADI), is administered by APRA and explained at fcs.gov.au.
The goal of this research framework is not to identify the "best" account — that depends entirely on your circumstances — but to make sure you are asking the right questions before you commit.
