Good Debt vs Bad Debt: Mortgages, HECS, Credit Cards, BNPL & Personal Loans Explained
Author: 10 min read |
Debt is not automatically a sign that something has gone wrong financially.
A mortgage may help you buy a long-term asset. HECS/HELP can support education and earning potential. A personal loan might fund something essential. But credit cards, Buy Now Pay Later (BNPL) accounts and even a home loan can become difficult when repayments start consuming money needed for rent, groceries, utilities and other essentials.
So, what is the difference between good debt and bad debt in Australia?
Good debt generally describes borrowing that may improve your long-term financial position or provide lasting value, provided the repayments remain affordable. Bad debt generally describes borrowing that is expensive, funds short-lived consumption or creates more financial pressure than benefit.
Importantly, “good debt” and “bad debt” are financial concepts, not legal categories. Whether a debt is helpful or harmful depends on its purpose, cost, repayment terms and your ability to afford it.
That distinction matters in 2026. ABS data shows Australian households borrowed $47.0 billion during the March 2026 quarter, with household credit demand continuing to be supported by housing loans. Moneysmart also reports that more than 280,000 financial hardship notices were recorded across Australia during the 2024–25 financial year.
| Factor | Good Debt May… | Bad Debt May… |
| Purpose | Build an asset or earning potential | Fund short-term consumption |
| Long-term value | Provide benefits beyond the loan term | Leave little lasting financial value |
| Cost. | Have manageable interest and fees | Carry high interest or recurring fees |
| Affordability | Fit comfortably within your budget | Put pressure on essential expenses |
| Repayment | Have a clear, sustainable repayment plan | Lead to minimum payments or repeated refinancing |
| Financial impact | Potentially strengthen your position | Increase financial stress and reduce flexibility |
The most important point is that the type of loan alone does not determine whether debt is good or bad.
A mortgage can become harmful if you cannot afford it. A personal loan can be reasonable if it solves an essential problem at a manageable cost. Even an interest-free BNPL purchase can create difficulties if several repayments fall due at the same time.
Good debt is usually borrowing taken on for something expected to provide longer-term value.
Common examples can include:
The key word is affordable.
Borrowing $600,000 for a house is not automatically better debt than borrowing $10,000 for another purpose. You still need to consider interest, fees, income stability, cash flow and what would happen if circumstances changed.
A mortgage is commonly described as good debt because it helps finance an asset that may provide long-term value.
Australian housing also represents a significant share of household borrowing. ABS figures for the March 2026 quarter show household credit demand remained strongly supported by owner-occupier and investor housing loans.
However, a mortgage is not automatically “good” just because it is attached to property.
It can become financially damaging when:
Because a home loan is secured against property, difficulties meeting repayments can have more serious consequences than falling behind on an unsecured debt.
If your mortgage is becoming difficult to manage, contacting your lender early is important. Moneysmart states that lenders must consider requests for financial hardship assistance and may offer arrangements such as altered repayments or a payment plan depending on the circumstances.
HECS/HELP is different from an ordinary bank loan.
Study and training loan balances are indexed annually rather than operating like a conventional interest-bearing personal loan. The ATO applies indexation on 1 June to eligible debt that has remained unpaid for more than 11 months.
Major changes have also occurred recently.
The Australian Government legislated a 20% reduction for eligible study and training debts that existed on 1 June 2025, and the ATO says processing of that reduction has been completed.
For 2026–27, compulsory repayments use the newer marginal repayment system. The ATO’s current table shows no compulsory repayment at repayment income up to $67,000, with repayments beginning above that point.
For these reasons, HECS/HELP is often viewed differently from high-interest consumer debt.
But that does not mean it should be ignored. It remains a financial obligation, and your individual circumstances should determine whether making additional voluntary repayments makes sense.
Credit cards can be useful payment tools, particularly when the balance is cleared before interest applies.
The problem begins when the balance becomes persistent.
Moneysmart reported in January 2026 that Australians owed around $33 billion on credit cards, with approximately $18 billion accruing interest. It cited an average credit card interest rate of around 18%.
Credit card debt is more likely to become “bad debt” when you:
If you’re asking, “What happens if I can’t pay my credit card?”, don’t wait until several payments have been missed. Contact the lender’s hardship team and explain what you can realistically afford.
Financial hardship arrangements do not automatically reduce your credit score. Moneysmart says hardship information can appear on your credit report but is removed after 12 months.
BNPL services can look less serious than a traditional loan because many purchases are advertised as interest-free.
But interest-free does not mean consequence-free.
Moneysmart warns that BNPL can make overspending easier, multiple services can be difficult to manage, fees can accumulate, and applications or missed repayments may appear on a credit report.
Australian regulation has also changed.
Since 10 June 2025, BNPL providers have been brought under Australia’s consumer-credit framework and generally need an appropriate Australian credit licence. The reforms extended a modified form of the National Credit Code to BNPL contracts.
BNPL becomes concerning when you are:
The individual purchases might be small, but several repayments falling in the same week can place significant pressure on household cash flow.
A personal loan can be either.
Moneysmart explains that personal loans can be used for expenses such as cars, holidays or home improvements and are generally repaid with interest over a fixed period. Personal loans may be secured or unsecured, with unsecured loans typically carrying higher interest rates.
A personal loan may be reasonable when it:
It becomes more problematic when it is used to fund discretionary spending you could not otherwise afford, or when new loans are repeatedly taken out to cover old debts.
When comparing personal loans, look beyond the advertised interest rate. ASIC’s National Credit Code requires comparison rates in relevant fixed-term consumer-credit advertising because the comparison rate incorporates the interest rate plus most fees and charges.
Yes. This is one of the biggest misconceptions about debt.
A debt that originally made financial sense can become difficult because life changes.
For example:
Mortgage: Affordable when you bought the property, but difficult after an income reduction.
Personal loan: Initially manageable, but stressful after unexpected medical expenses.
Investment debt: Taken on expecting future returns, but repayments become difficult when income or investment performance changes.
What determines whether debt remains manageable is not simply what you borrowed for. It is whether the ongoing cost still fits your financial circumstances.
Consider taking action if you are:
Moneysmart recommends starting by listing every debt, including the balance, interest rate, fees, remaining term and monthly repayment. It specifically recommends including BNPL, credit cards, loans, unpaid bills and fines when assessing what you owe.
There is no universal order that suits every household.
Two common strategies are:
Direct extra repayments towards the debt charging the highest interest while maintaining required payments on your other debts.
This can reduce interest costs faster.
Focus on clearing your smallest debt first before moving to the next.
This can create an early sense of progress and simplify the number of repayments you manage.
Moneysmart recognises both approaches when discussing credit-card repayment strategies.
Before making extra repayments, however, make sure priority essentials such as housing, food, utilities and necessary transport remain affordable.
If you are struggling with credit cards, BNPL, personal loans or several debts at once, the goal should not be to find another label for the debt.
The priority is to understand your options.
Depending on your circumstances, options may include:
No debt solution is appropriate for everyone.
For example, refinancing unsecured debt into a mortgage may reduce the interest rate, but it can also extend repayment over a much longer period and convert unsecured debt into debt secured against your home.
Likewise, a formal Part IX Debt Agreement has significant consequences and should not be viewed as a quick credit-repair strategy.
A Part IX Debt Agreement can significantly affect your ability to obtain credit, but describing that as simply “ruining” your credit score misses important context.
AFSA states that details of a debt agreement may appear on credit-reporting records for up to five years or longer in some circumstances. Debt agreements are also recorded on the National Personal Insolvency Index for a prescribed period.
That is why a formal debt agreement should only be considered after understanding the consequences and comparing available alternatives.
If your situation only involves temporary hardship, contacting your lender early may provide other options.
Australia’s core consumer-credit framework is national. ASIC administers the National Consumer Credit Protection Act and National Credit Code across Australia rather than separate consumer-credit regimes for NSW, Victoria, Queensland or other states.
That means Australians seeking debt help in Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Canberra, the Gold Coast or regional Australia have access to broadly consistent national consumer-credit protections.
However, some issues connected with debt—such as tenancy, fines, utilities and certain enforcement processes—can involve state or territory rules, so local financial counselling or legal advice may also be appropriate.
The National Debt Helpline provides free, confidential and independent financial counselling on 1800 007 007, with telephone support currently available weekdays from 9:30am to 4:30pm and online chat from 9:00am to 8:00pm.
The real difference between good debt and bad debt is more complicated than “mortgage good, credit card bad.”
Ask four questions:
A mortgage, HECS/HELP debt or personal loan may support worthwhile long-term goals. Credit cards and BNPL can also be manageable when used carefully.
But any debt can become a problem when repayments stop fitting your budget.
If repayments are already becoming difficult, getting help earlier may give you more options.
Debt Fix provides debt support Australia-wide. If you’re juggling credit cards, BNPL, personal loans or multiple repayments, you can request a free debt assessment to understand the options that may be available based on your circumstances.
General information only. This article does not constitute personal financial or legal advice. Eligibility, costs, risks and outcomes vary between debt solutions.
Good debt generally refers to borrowing that may provide lasting financial value, such as purchasing a suitable home, investing in education or financing a productive asset. Whether it is genuinely beneficial still depends on affordability, cost and risk.
Bad debt generally refers to borrowing that is expensive, finances short-lived consumption or places unnecessary pressure on your finances. Persistent high-interest credit-card balances are a common example.
A mortgage may be considered good debt because it finances a long-term asset. However, a mortgage can become harmful if repayments become unaffordable or other debts are repeatedly rolled into the home loan.
HECS/HELP is generally treated differently from conventional consumer debt because repayments are income-contingent and the balance is indexed rather than charged conventional loan interest. Your individual circumstances should determine how you prioritise it.
No. Using a credit card and clearing the balance before interest applies can be manageable. Carrying high-interest balances month after month is more likely to create financial difficulty.
BNPL is a form of credit, and Australian regulation now brings BNPL contracts within the consumer-credit framework. Providers are subject to licensing and other requirements under reforms effective from June 2025.
