The Real Cost of Carrying Multiple Debts
Australian credit cards typically charge between 18% and 22% p.a., personal loans sit around 10-15%, and car loans run in the 6-12% band. Standard variable home loan rates in 2026 hover closer to 6.3-6.7%. Rent, groceries and utilities have climbed across every capital city, and the gap between payday and the bills is often bridged with plastic. When the National Debt Helpline reported its busiest year on record, with more than 183,000 Australians reaching out for support, it underlined how many households are juggling high-interest balances.
Carrying $15,000 on a card at 20% costs roughly $3,000 a year in interest alone. Move that onto a personal loan at 11% and the annual interest drops to about $1,650. That saving of more than $1,300 a year could go toward the principal instead of vanishing into interest.
The hidden cost of multiple debts is not just the rate. It is the chaos. Different due dates mean missed payments, late fees, and a credit score that slowly erodes. A single late fee on one card can wipe out the savings from a low rate on another, and the stress of tracking five due dates pushes many people to miss one eventually. Lenders see the pattern, and a weaker score means higher rates on everything you borrow next.
The Main Consolidation Routes
Most Australians consolidate through one of three routes. Each fits a different situation, and the table below summarises the trade-offs.
Personal Loans
A debt consolidation loan pays out your existing debts in one transaction, leaving a single fixed or variable repayment. Major lenders typically offer up to $75,000 over one to seven years. A fixed rate protects you from interest movements for the life of the loan, while a variable rate lets you pay it off sooner without exit fees. For renters without home equity, this is usually the only consolidation route, which is why it remains the most popular option in cities like Sydney and Melbourne where mortgage repayments already absorb a large share of household income.
Balance Transfer Credit Cards
If all your debt sits on credit cards, a balance transfer card moves those balances onto a new card with a low introductory rate, often lasting 12 to 24 months. This works well if you can clear the balance before the promotional window closes. Factor in the transfer fee, and remember that new purchases on the card attract the standard rate from day one. A single missed payment during the promotional period can also void the low rate, so automatic repayments matter more than ever here.
Home Loan Refinancing
Homeowners with equity can refinance the mortgage and use the extra funds to clear unsecured debts. At 6-7%, the interest saving against a 20% card is substantial. But you are converting unsecured debt into secured debt, and spreading it across a 25-year mortgage term can cost more overall than a shorter personal loan at a slightly higher rate. Run the comparison on total interest, not just the monthly repayment.
| Option | How it works | Typical rate range | Best suited to | Key watch-out |
|---|
| Personal loan | One loan pays out all other debts | 10-15% p.a. | Multiple debt types, amounts up to $75,000 | Compare the comparison rate, not the headline rate |
| Balance transfer card | Move card balances to a low intro rate | Low intro rate, then reverts | Credit card debt only | Transfer fee and the rate after the intro period |
| Home loan refinance | Extra borrowing against the property | 6-7% p.a. | Large debts with home equity | Longer term and losing unsecured protections |
Why Consolidation Fails and How to Make It Stick
The most common failure is not the loan itself but what happens afterwards. Borrowers consolidate, clear the cards, then rebuild the balances within a year or two. They end up with a consolidation loan plus fresh card debt, which is worse than where they started.
Sarah, a Brisbane teacher, rolled $12,000 of card debt into a personal loan and felt instant relief at having one repayment. Then an emergency car repair went onto the cleared card, and the balance started climbing again. Her financial counsellor gave one blunt instruction: lower the credit limit or cancel the card before it becomes a trap.
Marcus in Melbourne took a different path. He used a balance transfer card for $9,000 of card debt, set automatic payments to clear it inside the 18-month promotional period, and closed the old cards. It took discipline, but he paid roughly a third of the interest he would have paid on the original cards.
There is also the quieter trap of extending the term. A longer loan lowers the monthly figure but adds years of interest, so the total cost climbs even as the repayment shrinks. The goal is to pay less overall, not to stretch the debt out. The pattern in both stories is the same: consolidation only works with a plan. Budget for the repayment, automate it, and cut off access to the old credit before it lures you back.
A Workable First Step
List every debt with its lender, balance, rate and minimum repayment. Moneysmart, the government's financial guidance site, provides a debt calculator and templates for this exact exercise. Then request a copy of your credit report from the major reporting bodies, because your score determines the rate you will be offered.
Compare at least three options using comparison rates, which fold in fees. The lowest headline rate is not always the cheapest loan once establishment and ongoing costs are added. If you are consolidating cards, ask about lowering or closing the cleared accounts as part of the process.
Getting Help Along the Way
A financial counsellor can walk through your numbers and tell you honestly whether consolidation is the right move or whether a hardship arrangement suits better. The National Debt Helpline on 1800 007 007 connects you with counsellors who provide independent advice at no cost, and the service has never been busier. Financial counselling is available in every state and territory, so help is never far away.
Consolidation is a tool, not a cure. Done properly, it turns a pile of confusing debts into one manageable repayment at a lower rate. Done carelessly, it stretches the debt out and frees up credit to be used again. The difference is the plan you build around it. Pull out your statements, run the numbers, and take the first step this week.
