Australians collectively owe around $43.77 billion on their credit cards, and nearly half of that balance — about $21.40 billion — is accruing interest at an average rate of 18.59% per year. That means millions of households are paying hundreds or thousands of dollars annually just to carry debt from one month to the next. Here’s what you actually need to know.

That last figure is worth sitting with. Nearly two-thirds of Australians avoid interest charges entirely by paying in full. The other third — roughly 4 million accounts — are the ones feeding the interest machine. If you’re in that group, the numbers stack against you fast. A $5,000 balance at 20% interest, paid only at the minimum rate, can take over 30 years to clear and cost more than $12,000 in interest alone. That’s not a debt — that’s a second mortgage on a pair of jeans and a few takeaway dinners.
The good news is that the mechanics of getting out are straightforward, even if the discipline isn’t. Whether you’re carrying a few hundred dollars or tens of thousands, the path involves the same basic levers: interest rate, payment amount, and time. What changes is which strategy fits your situation. I’ve looked at the research on what actually works in Australia, and the options range from mathematical optimisation to behavioural hacks. Let’s walk through them.
What You Need to Know About Paying Off Credit Card Debt
The central concept here is the revolver — someone who carries a balance month to month rather than paying it off in full. About 30% of Australian cardholders are revolvers, and their average accruing balance sits around $5,800. If that sounds like you, the interest alone is costing roughly $1,050 per year on a $5,000 balance at 20.99%. That’s money that could be going into savings, investments, or frankly anything else.
What I tend to notice is that people underestimate how quickly interest compounds on a revolving balance. It’s not a flat fee — it’s calculated daily on the outstanding amount, so every day you carry debt, you’re paying for yesterday’s spending plus today’s interest. Understanding that mechanism is the first step to breaking the cycle.
The Real Cost of Carrying a Balance
When you only make the minimum payment on a credit card, you’re essentially renting your own money from the bank. The minimum — typically 2–3% of the balance or $25, whichever is higher — mostly covers the interest charge, with a tiny sliver going toward the principal. That’s why a $5,000 balance at 20.99% takes 32 years to pay off if you only pay the minimum. You’re not repaying debt; you’re maintaining it.
The numbers get worse the higher your balance climbs. On a $10,000 balance at the same rate, you’re looking at roughly $2,099 in interest per year — that’s $175 a month that vanishes before you’ve paid down a single dollar of what you actually spent. And because the interest is calculated daily, even a few days’ delay in payment can add to the total.
There’s also a less obvious cost: your borrowing power. Lenders look at your total credit limit, not just your balance, when assessing a mortgage application. A high limit on an unused card can reduce how much you can borrow for a home. So carrying debt doesn’t just cost you in interest — it can delay major life goals. If you’re in that boat, it’s worth weighing the trade-off between keeping a card open for emergencies versus freeing up borrowing capacity for something bigger.
Where People Go Wrong With Credit Card Debt
Only making the minimum payment
This is the single most expensive mistake. As we’ve seen, minimum payments stretch repayment into decades. The fix is to set a fixed payment amount above the minimum — even $50 extra per month cuts years off the repayment timeline. Set up an automatic transfer from your transaction account on payday so you never miss it.
Using a balance transfer without a plan
A 0% balance transfer card can be a powerful tool, but only if you treat the promotional period as a deadline. If you don’t pay off the full balance before the rate reverts — typically to 22–25% — you’re back where you started, often with a transfer fee (1–3%) already sunk. The fix: divide your balance by the number of interest-free months, set that as your automatic payment, and set a calendar reminder one month before the promo ends.
Closing cards too early or not at all
Closing a credit card account can hurt your credit score by reducing your available credit and shortening your credit history. But leaving a card open with a high limit can also hurt your borrowing power for a mortgage. The middle ground: pay off the card, keep it open with a low limit or no annual fee, and use it sparingly — or close it only after you’ve secured any major loan you’re planning.
Taking on new debt while paying off old debt
This is the cycle that keeps people stuck. If you’re making progress on a balance but still using the card for new purchases, you’re effectively paying interest on both old and new spending. The fix is to stop using the card entirely during the repayment period. Switch to a debit card or cash for everyday spending. If that feels impossible, consider whether the card needs to exist in your wallet at all.
How to Actually Pay Off Your Credit Card Debt
Choose your repayment strategy: avalanche or snowball
The debt avalanche method is mathematically optimal. List all your debts from highest to lowest interest rate, make minimum payments on everything except the highest-rate debt, and throw every extra dollar at that one. Once it’s gone, move to the next highest rate. This minimises total interest paid.
The debt snowball method ignores interest rates and focuses on balance size instead. Pay off the smallest balance first, regardless of rate, then roll that payment into the next smallest. Behavioural research suggests people are more likely to stick with this method because the early wins provide motivation. Both work — the best one is the one you’ll actually follow.
Use a balance transfer strategically
If you have good credit, a balance transfer card with a 0% promotional period can give you breathing room. Current offers in Australia range from 12 to 30 months at 0%, with transfer fees between 1% and 3%. On a $6,000 balance, a 24-month 0% card saves roughly $2,400 compared to a 20% card, even after a $120 transfer fee. The key is to calculate your monthly payment — $6,000 divided by 24 months equals $250 per month — and automate it. Do not use the card for new purchases during this period.
Consider a debt consolidation personal loan
Personal loan rates for debt consolidation typically range from 8% to 12%, which is significantly lower than the average credit card rate of 18–22%. A loan consolidates multiple debts into a single monthly payment with a fixed term. The trade-off is that you need to qualify based on your credit score, and you must avoid running up new card balances after the loan is approved. If discipline is an issue, this can be a clean reset.
Cut spending and increase income temporarily
This is the least glamorous method but often the most effective. An extra $200 per week toward a $5,000 credit card balance clears it in about six months instead of 30 years. That $200 can come from cutting non-essential spending — dining out, subscriptions, takeaway coffee — or from a side hustle, overtime, or selling unused items. The key is to treat it as a short-term sprint, not a permanent lifestyle change. Three to six months of focus can eliminate years of payments.
