Comparison sites will tell you which Australian account has the highest advertised rate this week. More useful is knowing what the market actually pays across account types, because the difference between them dwarfs the difference between banks within a type.
The RBA publishes exactly that, monthly, and the spread is remarkable.
What the market pays, by account type

Transaction accounts, for completeness, averaged 0.00%.
That’s the finding worth internalising: 4.80% and 0.55% are both available to the same person, for the same money, with the same protection. The account type decides more than the bank does.
Bonus savings accounts: the rate is conditional
The 4.80% figure is an average of bank bonus savings rates, and the word bonus is doing real work.
These accounts pay a low base rate plus a bonus in any month you meet conditions. Typical conditions:
- A minimum monthly deposit: often a few hundred dollars, from an external source
- No withdrawals during the month
- A linked transaction account, sometimes with its own activity requirement
- A growing balance: the balance must be higher at month end than at the start
Miss one and you get the base rate for that month, which can be a fraction of the headline. Nobody sends a warning.
So the practical question isn’t “which account advertises the most?” It’s “which conditions will I actually meet every month, for years, without thinking about it?” An account paying slightly less unconditionally can beat a higher one you fail twice a year.
Introductory rates expire
The second structural feature: many bonus rates are introductory, running for a set number of months before dropping to something ordinary.
Diarise the end date the day you open the account. This is the single most common way Australian savers quietly end up on a poor rate — not by choosing badly, but by not revisiting.
What the rate environment is doing
Context matters here more than usual, because Australia is not where the rest of the English-speaking world is.
The RBA raised the cash rate three times during 2026 (75 basis points in total) and held at 4.35% on 11 August while it assessed the effect and the impact of an oil supply disruption. Australian savers are in a tightening cycle.
For comparison, in the same month the Bank of England sat at 3.75%, the US Federal Reserve at 3.50–3.75%, and the Bank of Canada at 2.25%. A savings article written for an American audience is describing a different market — worth remembering when you land on one.
How to actually choose
1. Rule out the wrong account type first. If your money is sitting in a transaction or cash management account, moving it to a competitive savings product is worth more than any comparison between banks.
2. Read the conditions before the rate. Write down what you’d have to do each month. If it’s more than one automatic transfer, be honest about whether you’ll sustain it.
3. Check whether the headline is introductory, and for how long.
4. Confirm the licence. FCS protection is A$250,000 per account holder per ADI, and it aggregates across brands operating under one banking licence. If you hold more than that, split across genuinely separate licences.
5. Check the base rate. It’s what you’ll earn in the months life gets in the way. Over several years, that number matters more than the bonus.
If you can lock the money away
Term deposits are paying more than savings at some tenors right now, which is unusual and worth checking before you settle on an at-call account — the Australian term deposit curve has the numbers and the catch.
Get the account type and the conditions right, and the specific bank you pick barely moves the number. The savings accounts guide breaks down how the other three markets stack up if you’re comparing across borders.
