When High-Interest Debt Starts to Snowball
Recent RBA data shows Australians charged $28 billion to credit cards in a single December, with nearly $18 billion of that balance attracting interest. ASIC surveys paint an equally sobering picture: close to half of Australian debtors have said they struggle to make repayments on time.
The numbers rarely work in the borrower's favour. Credit cards typically charge 18 to 22 per cent p.a., personal loans and car loans sit in the mid-to-high single digits, and a home loan often comes in well under that. Every dollar spent on interest is a dollar that cannot touch the principal.
There is also the mental load. Four repayment dates to track, several minimum payments, and one missed deadline can trigger late fees and a mark on your credit file. Many borrowers describe the feeling of running on a treadmill — paying every month, yet watching the balances barely move.
That is exactly the situation a debt consolidation loan is designed to fix. You take out one new loan, use it to pay off the existing debts, and go forward with a single repayment, a single rate and a clear end date.
Three Routes to a Single Repayment
Refinance your home loan to consolidate
For homeowners with $20,000 or more in combined debts, rolling everything into the mortgage is usually the most cost-effective move. Home loan rates sit around 6 to 7 per cent, far below unsecured credit. A mortgage broker can arrange a refinance that pays out your cards and loans while keeping repayments manageable.
The trade-off is real. The debt becomes secured against your home, and the loan term often stretches out. You might pay less each month while owing more overall. For borrowers who can commit to keeping the cards closed, the interest savings are substantial. For those who cannot, the risk deserves a hard look.
Take out a dedicated debt consolidation loan
Renters and borrowers with smaller balances often choose an unsecured personal loan instead. Australian lenders advertise rates starting from around 5 per cent p.a., with approval times ranging from 15 minutes to a couple of days. Comparing current offers shows Alex Bank from 4.99 per cent, Plenti from 6.39 per cent, Harmoney from 6.99 per cent and SocietyOne from 7.50 per cent, with loan sizes typically between $2,000 and $100,000 depending on the lender.
The key is to compare the comparison rate, not the headline figure, and to factor in establishment fees. Some lenders, including Pepper Money, charge no establishment or early repayment fees, which matters if you plan to pay the loan off ahead of schedule.
Use a balance transfer credit card
If your debt sits entirely on credit cards, a balance transfer card can give you breathing room at 0 per cent interest for a set period. Some current Australian offers extend the interest-free window to 24 months. You pay a transfer fee of roughly 1 to 3 per cent and need a realistic plan to clear the balance before the promotional period ends.
Balance transfers suit disciplined borrowers. If the balance is still there when the 0 per cent period finishes, the revert rate is usually around 20 per cent, and you are back where you started.
How the options stack up
| Option | Best suited to | Typical rate | Loan size | Advantages | Watch out for |
|---|
| Refinance home loan | Homeowners with $20k+ combined debt | 6–7% p.a. | Large | Lowest rate, one repayment | Debt secured against home, longer term |
| Debt consolidation loan | Renters, smaller balances | From ~5% p.a. | $2k–$100k | Fast approval, unsecured | Higher rate than a mortgage, possible fees |
| Balance transfer card | Credit card debt only | 0% intro | Card limit | Interest-free window | Transfer fee, high revert rate |
The Catch Most People Discover Too Late
Debt consolidation fixes the structure of your debt, not the habits that created it. Research into Australian borrowers found the most common outcome is that people clear their credit cards, then rebuild the balances within 12 to 24 months. They end up with a larger mortgage or personal loan and fresh card debt on top.
Sydney mortgage broker Andrew Wallace from Crowd Property Capital shared a striking case on the New Broker podcast. A client carried a mortgage, credit card debt, private loans and $20,000 owed to family after a failed business venture. Wallace consolidated everything into a single loan and cut the monthly outgoings by $500. The client's finances stabilised, and they later called back about buying a second property.
That outcome was possible because the underlying problem got addressed. The client stopped using the credit facilities, stuck to the single repayment, and rebuilt from there.
What to Do Before You Sign Anything
Start with a full inventory. Write down every debt — the balance, the interest rate and the minimum repayment. That list tells you whether consolidation actually saves money, and it gives lenders the documentation they need.
Check your credit score before applying, because it shapes which lenders will consider you and at what rate. Then compare at least three offers side by side, using the comparison rate as your reference point rather than the advertised rate.
Have a plan for the cards. The single most effective move is closing the credit card accounts once the consolidation loan pays them out. If you keep them open, set a rule — no new purchases — and stick to it.
Finally, run your budget through the 50/30/20 guideline: half your income to essentials, 30 per cent to discretionary spending, and 20 per cent to savings and debt repayment. A consolidation loan makes that last slice go further.
Where to Find Help
Self-employed borrowers and small business owners have their own path. Non-bank lenders such as Pepper Money and Liberty underwrite applications that the big banks often decline, including cases where the debt sits with the ATO. Recent changes removed the tax deduction on ATO interest charges, which has pushed more businesses to consolidate sooner rather than later. The Small Business Debt Helpline on 1800 413 828 offers specialist financial counselling for business owners.
For households, the National Debt Helpline on 1800 007 007 connects you with independent financial counsellors who can review your situation before you commit to a loan. MoneySmart, run by ASIC, provides budgeting tools and calculators that help you test whether consolidation works for your numbers.
Consolidation is not a magic wand. It is a restructuring tool, and it works best when the spending habits that created the debt change alongside it. Done well, it turns a pile of scattered repayments into a single, predictable monthly amount — and that predictability is often worth as much as the interest savings. If the numbers stack up after you have done the homework, talk to a broker or lender and get a formal quote. One repayment beats five, every time.
