Three proven strategies to clear credit card debt in Australia — the debt avalanche (minimises total interest), the debt snowball (fastest psychological wins), and balance transfers (0% window). With worked cost comparisons.
Credit card interest rates are consistently the highest of any common consumer debt in Australia. While the RBA cash rate sits at 4.35%, most Australian credit cards charge 17–23% p.a. on purchases — regardless of what other interest rates are doing. This gap between credit card rates and market rates has not meaningfully narrowed since the cash rate began rising in 2022.
The real trap is minimum repayments. Australian credit card minimum repayments are typically 2% of the outstanding balance. On a $10,000 balance at 19.99%:
| Payment Approach | Monthly Payment (initial) | Years to repay | Total Interest Paid |
|---|---|---|---|
| Minimum payments (2% of balance) | ~$200 (declining) | 20+ years | ~$15,000+ |
| Fixed $300/month | $300 | ~4.5 years | ~$5,500 |
| Fixed $500/month | $500 | ~2.3 years | ~$2,600 |
| Fixed $1,000/month | $1,000 | ~11 months | ~$1,100 |
Enter your balance, interest rate, and monthly payment to see exactly when you'll be debt-free.

Assume you have three cards with a total of $15,000 debt and $600/month available for debt repayment:
| Card | Balance | Rate | Minimum |
|---|---|---|---|
| Card A (rewards) | $5,000 | 22.99% | $100 |
| Card B (standard) | $7,000 | 19.99% | $140 |
| Card C (low rate) | $3,000 | 12.99% | $60 |
Pay $100 (min) on B, $60 (min) on C, and $440 extra on Card A (the 22.99% card). Once Card A is cleared, roll the freed-up $540 to Card B, then $600 to Card C. Total interest saved versus minimum payments: thousands of dollars.
The debt snowball pays off the smallest balance first regardless of interest rate, then rolls the freed payment to the next smallest. It does not minimise total interest paid — but it provides faster psychological wins that help many people sustain momentum.
Using the same example, under snowball you'd attack Card C ($3,000) first despite its lower rate, then Card A ($5,000), then Card B ($7,000). Total interest paid is higher than avalanche, but Card C is fully paid off faster — providing visible progress that is genuinely motivating for many people.
A balance transfer moves your existing credit card debt to a new card offering a 0% promotional interest rate for a defined period — typically 6 to 24 months in Australia. During this window, every dollar you pay reduces the principal rather than going partly to interest.
Rolling multiple credit card debts into a single personal loan at a lower rate is a legitimate strategy for people who have reasonable credit and can qualify for a competitive personal loan rate (7–12% p.a. versus 20%+ on cards).
The key discipline requirement: closing the credit card accounts after paying them off with the loan. Many people consolidate, feel financial relief, and then re-spend on the now-clear cards — ending up with more total debt than before. The consolidation loan only saves money if the cards stay closed or at zero balance.
| Situation | Best Strategy |
|---|---|
| Multiple high-rate cards, motivated by numbers | Debt Avalanche |
| Previously struggled with motivation to continue | Debt Snowball |
| Good income, can clear most of the balance in 12-18 months | Balance Transfer |
| Multiple cards, stable income, good credit score | Consolidation Personal Loan |
| Serious financial hardship, cannot meet minimums | Contact National Debt Helpline 1800 007 007 |
The minimum payment on an Australian credit card is typically calculated as a small percentage of the outstanding balance, subject to a small dollar floor. Because it is a percentage of a shrinking balance, the payment shrinks too — and the payoff period stretches.
Paying only the minimum on a substantial balance at a typical credit card rate can take well over a decade, with total interest paid frequently exceeding the original balance. Australian credit card statements are required to display an estimate of how long repayment will take at the minimum, and the figure is worth reading rather than skipping.
Withdrawing cash on a credit card — including gambling transactions, some transfers, and buying foreign currency — is generally treated as a cash advance. Two things typically apply that do not apply to purchases.
First, there is usually no interest-free period. Interest accrues from the transaction date, not from the statement date. Second, the cash advance rate is commonly higher than the purchase rate, and a fee applies immediately.
Worse, some card terms allocate your repayments to the lowest-interest balance first. Where that occurs, a cash advance can sit accruing at the highest rate while your payments retire cheaper purchase debt. Check your card's payment allocation terms.
A card with a zero balance and an open limit is an invitation and an obligation. The available limit — not the balance — is generally assessed by lenders when calculating how much you can borrow, so an unused card can reduce your mortgage borrowing capacity.
If credit card debt has become unmanageable, free, independent and confidential financial counselling is available through the National Debt Helpline on 1800 007 007. Financial counsellors are not selling anything and can negotiate with creditors on your behalf.

Does paying off a credit card help my credit score in Australia?
Yes. Reducing credit card utilisation (the ratio of your balance to your credit limit) is one of the most impactful factors in improving your credit score under the Comprehensive Credit Reporting system used in Australia. Paying down balances, and especially clearing cards to zero, improves your score and also increases your home loan borrowing capacity (since lenders treat credit limits as committed repayments).
Should I close credit card accounts once they are paid off?
It depends. Closing old cards reduces your total available credit and potentially increases your utilisation ratio on remaining cards, which can temporarily lower your credit score. However, having open cards with zero balance tempts spending on credit. For most people paying off debt, the discipline benefit of closing the card outweighs the minor credit score impact — particularly if you are also planning to apply for a home loan.
Can a financial counsellor help with credit card debt in Australia?
Yes. The National Debt Helpline (1800 007 007) provides free, confidential financial counselling from qualified professionals. Financial counsellors can help you understand your options including negotiating with creditors, hardship arrangements, and formal debt solutions. This service is free and available to anyone in financial difficulty.
