The Australian credit card landscape today
Reserve Bank data tells a striking story: Australians collectively hold around 14.7 million credit cards with roughly $33 billion owing on them. Almost $18 billion of that balance is accruing interest, and the average purchase rate sits above 18% p.a. That means a $5,000 balance can quietly cost over $900 a year in interest alone if you only make minimum repayments.
Three mistakes tend to trip people up. First, chasing a rewards credit card while carrying debt. Points sound great, but at 20% p.a. interest, every $100 of points you earn can cost you far more in interest charges. Second, misunderstanding interest-free days. Those 44 to 55 days only apply when you pay your statement balance in full by the due date. Miss that, and interest is charged on purchases from the transaction date. Third, ignoring the fine print on balance transfers. A 0% offer is only a bargain if you have a realistic repayment plan before the promotional period ends.
Matching a card to your habits
The best credit card in Australia depends entirely on how you use it. If you pay your balance in full each month, a rewards card makes sense. If you sometimes carry a balance, a low rate card will save you more than any points program ever will.
For travellers, cards with Qantas or Velocity partnerships are popular. The ANZ Frequent Flyer Black, for example, currently offers up to 130,000 Qantas Points plus $200 back, though the $425 annual fee means you need to travel regularly to justify it. Westpac's Altitude Velocity Black similarly targets Virgin flyers with lounge passes and Economy X upgrades.
For everyday spenders, the St.George Amplify Rewards Signature offers up to 200,000 bonus Amplify Points across two years, with a $199 first-year fee dropping to $295 after that. The catch? You need to spend $12,000 per year to unlock the full bonus, so it suits households with higher everyday expenses.
If you prefer simplicity, cards like the CommBank Low Rate Card start from 10.99% p.a. with 55 interest-free days, charging a $6 monthly fee. American Express offers a low rate card with a $0 annual fee at 10.99% p.a., though Amex is not accepted everywhere, so it helps to keep a Visa or Mastercard as backup.
| Card | Best for | Annual fee | Purchase rate | Notable feature |
|---|
| CommBank Low Rate | Carrying a balance | $6/month | from 10.99% p.a. | 55 interest-free days |
| Amex Low Rate | No annual fee | $0 | 10.99% p.a. | Simple, no rewards |
| ANZ Low Rate (Balance Transfer) | Consolidating debt | $58 | 13.74% p.a. | 0% for 26 months on transfers |
| ANZ Frequent Flyer Black | Qantas flyers | $425 | 20.99% p.a. | 130,000 bonus points + $200 back |
| St.George Amplify Rewards Signature | High everyday spend | $199 first year | varies | 200,000 bonus points over 2 years |
| Westpac Altitude Velocity Black | Virgin flyers | $425 + $75 program fee | varies | 150,000 Velocity points over 2 years |
Getting out of credit card debt
If you are already carrying a balance, the priority is reducing interest, not earning points. The ANZ Low Rate card offers a 0% p.a. balance transfer for 26 months, which is among the longest windows available. A 3% transfer fee applies, so on a $10,000 transfer that is $300, but compared with 18% interest over two years, the savings are substantial.
Moneysmart, the government's financial guidance service, suggests a straightforward approach. Check all your card balances and rates first. If one card charges significantly more than another, move that debt to the cheaper option. Then work out a monthly repayment figure you can genuinely sustain, and attack the highest-rate card first while making minimum payments on the rest. Reducing your credit limit is another practical step. You can request this online or by phone, and most providers process it within a couple of business days.
Sarah, a Brisbane nurse, recently used this strategy. She had $8,000 spread across two cards, one at 19.99% and one at 13.99%. She transferred both balances to a 0% balance transfer card, set up a direct debit for $350 a fortnight, and had the debt cleared in 12 months. The key, she says, was treating the transfer as a short-term tool and cutting the cards up until the balance hit zero.
Interest-free days and everyday use
Understanding interest-free days is worth its own paragraph because it is the most misunderstood feature on any Australian credit card. If you pay your closing balance in full by the due date each month, purchases made at the start of a statement period can effectively be interest-free for up to 55 days. That is a genuine benefit, giving you a free short-term loan for everyday expenses.
The trap appears when you pay only part of the balance. Interest is then charged on all purchases, often from the day each transaction was made, not from the statement date. A single missed full payment can wipe out months of careful planning. Set up an automatic direct debit for the full balance and you remove the risk entirely.
For those who use credit cards for travel, several banks include travel insurance cover and purchase protection on their premium cards, though NAB has flagged changes to some of these covers from May 2026, so it pays to read the product disclosure statement before relying on them.
Practical steps to choose and manage your card
Start by pulling up your last three months of spending. If you pay in full every month and spend heavily on groceries, fuel and dining, a rewards card like the St.George Amplify Signature or ANZ Frequent Flyer Black can deliver real value. If you carry a balance for more than a few months a year, skip rewards entirely and look at the low rate options from CommBank or Amex.
Next, compare the fine print. Check the annual fee, the cash advance rate, international transaction fees and any monthly account keeping charges. A card with a $0 annual fee but a high international conversion fee will cost you more on overseas trips than a premium card with a modest fee and no conversion surcharge.
Finally, review your card once a year. Banks regularly change interest rates and fee structures, and the card that suited you two years ago may no longer be competitive. A quick comparison of balance transfer offers and low rate cards can save hundreds of dollars with minimal effort.
The right credit card for you is the one you never pay interest on, or the one with the lowest rate if you do. Choose based on your behaviour, not the marketing, and your wallet will thank you.
