Why so many Australians are sitting on expensive debt
Australians carry some of the highest household debt in the world, and much of it sits in the most expensive places. Credit card interest rates commonly run from around 18% to 23% per annum, and some cards push well past that. Buy-now-pay-later plans, once seen as a harmless way to split a purchase, have quietly become a second mortgage for many households. Recent regulatory changes now treat BNPL as a credit product, which tells you how seriously the problem is taken.
The typical picture looks like this: a credit card balance from last summer's holiday, a personal loan taken out for a car repair, a BNPL plan for a new phone. Each has its own repayment date, its own rate, and its own late fee. Miss one and the others do not care — the fees just stack up.
Rate blindness tops the list of problems: most people cannot tell you the interest rate on each of their debts, so they cannot see where the money leaks. Repayment fatigue follows, because juggling five due dates across a month leaves little room for error. And then there is the promo trap, a 0% balance transfer that sounds generous until the promotional period ends and the rate reverts to something closer to 20%.
How debt consolidation actually works
A debt consolidation loan combines two or more debts into a single loan with one monthly repayment. The idea is simple: if your credit cards charge around 20% and you can borrow at 10% or less, the gap between those rates is pure saving.
Consider a borrower carrying $15,000 across three credit cards at 20% per annum. Consolidating into a personal loan at 10% over three years would save roughly $2,500 in interest alone. That is real money, and it is the reason debt consolidation is one of the most searched personal finance topics in Australia.
The main consolidation options compared
| Option | Typical rate range | Loan size | Best for | Advantages | Things to check |
|---|
| Balance transfer card | 0% promo for a set period, then reverts to around 20% | Depends on your credit limit | Smaller credit card balances | No interest during the promo period | Transfer fee of a few per cent, rate reverts afterwards, easy to spend up again |
| Unsecured personal loan | From roughly 5% to 14% comparison rate | $2,000 to $80,000 | Most consolidations | Fixed repayments, clear end date, no asset required | Establishment fee, typically $0 to $600 |
| Secured personal loan | From around 5.67% | Up to $80,000 | Larger debts | Lower rate than unsecured options | Your asset backs the loan |
| Mortgage top-up | Around 6% to 7% for owner-occupiers | Depends on available equity | Homeowners with equity | Cheapest option by far | Extends the loan term, so total interest can climb |
The rates above reflect lender comparisons published in September 2026. The establishment fee range comes from industry calculators, and some lenders waive it entirely for larger amounts. Westpac, for instance, charged $250 on personal loans under $10,000 but only $100 on loans over $20,000 in its recent offers, while several digital lenders charge nothing at all.
Take Priya, a teacher in Melbourne who carried $18,000 across two credit cards and a BNPL plan. Her weighted average rate sat above 19%. By consolidating into an unsecured personal loan at around 9%, her repayments shrank to a single figure she could budget around, and the loan had a fixed three-year end date. The discipline of a fixed term, not just the lower rate, is what kept her on track.
Tom in Brisbane took a different path. As a homeowner with equity in his mortgage, he topped up his home loan instead of taking a personal loan. His rate was around six per cent, well below any unsecured alternative. The catch: his repayment term stretched out, which means he pays more interest overall unless he makes extra repayments. For him, that trade-off was worth it. For others, it can quietly undo the savings.
A step-by-step plan before you sign anything
Consolidation is a tool, not a cure. Before applying for anything, work through these steps.
List every debt with its balance, interest rate and minimum repayment. You cannot consolidate what you cannot see, and most people are surprised by what shows up, especially those small BNPL balances.
Request your credit report from a credit reporting body. Lenders will look at it, and so should you. A few errors or a forgotten default can change the rate you are offered by several percentage points.
Use a debt consolidation calculator. Moneysmart, the ASIC-run website, has one that shows the difference between your current repayments and a consolidated loan across different terms. Pay close attention to the loan term: a longer term lowers the monthly repayment but increases the total interest paid over the life of the loan.
Read the comparison rate, not just the headline rate. The comparison rate includes fees and tells you the true cost. A loan that looks cheap at 6.99% can end up more expensive than one advertised at 7.5% once establishment fees are added.
And if the numbers do not work, do not force them. Consolidating onto a longer term just to lower the monthly payment is the most common mistake in Australian debt consolidation, and it is entirely avoidable.
Where to get independent help in Australia
You do not have to figure this out alone. The National Debt Helpline on 1800 007 007 connects you with independent financial counsellors at no cost, and the service is open through the week. Moneysmart's website has plain-language guides on consolidation, credit scores and dealing with creditors. Mob Strong Debt Help on 1800 808 488 provides legal advice on money matters for Aboriginal and Torres Strait Islander peoples, and the Small Business Debt Helpline on 1800 413 828 exists for business owners carrying debt.
Financial counsellors are different from consolidation companies. They do not sell products, and they will tell you honestly whether consolidation is the right move or whether a hardship arrangement with your creditors makes more sense.
A consolidation loan makes sense when your current debts carry high interest, you have a stable income, and the new rate is materially lower. It makes less sense when the term stretches so far that the savings evaporate. Run the numbers, read the fine print, and if in doubt, call the helpline before you sign. One loan, one repayment, one end date — that is the goal, and with the right structure it is achievable.
