What 'major failure' really means under the Australian Consumer Law

You've got a faulty product. The business is offering to repair it — but you want a refund. Whether you can insist on a refund instead of a repair comes down to a single question: is the failure a major failure under the Australian Consumer Law?

That phrase — "major failure" — is the hinge point of almost every serious consumer dispute in Australia. Get it wrong and you may accept a repair when the law entitled you to reject the goods. This guide explains what the term means, how the law defines it, and what to do next.

Quick answer

Whether you can insist on a refund turns on whether the failure is major. Under section 260 of the ACL, a failure with goods is major where a reasonable consumer fully acquainted with the nature and extent of the failure would not have bought them at all, or where the goods are substantially unfit for their normal purpose (or unfit for a purpose you made known) and can't easily and within a reasonable time be fixed, depart significantly from their description, or are unsafe. Services have a parallel test in section 268. For a major failure with goods (or one that can't be remedied), you choose the remedy: reject the goods, if your right to reject hasn't been lost under section 262, for a refund or a replacement of the same type (if one is reasonably available), or keep them and claim compensation for the drop in value. The business does not get to decide. For services, you can cancel and get a refund for the unused part, or keep the service and claim compensation. The definition is more generous to consumers than many retailers admit.

What the law actually says

Section 260 of the ACL sets out five situations in which a failure to comply with a consumer guarantee is a major failure. You only need to satisfy one of them.

1. A reasonable consumer fully acquainted with the nature and extent of the failure would not have bought the goods.

This is the broadest test and the one that covers most serious defects. Picture someone walking into the shop knowing exactly what is now known about the fault: would a reasonable consumer have bought this item? The test is objective, so the question is not whether you personally would have walked away. If a reasonable consumer would not have bought it, the failure is major. A laptop that randomly shuts down mid-use, a fridge that doesn't hold temperature, a car that stalls on the freeway: these are failures a reasonable buyer would have walked away from.

2. The goods are significantly different from their description, sample, or demonstration model.

This overlaps with the guarantee in section 56 (match the description). If the item you received is substantially not what was advertised — not a minor variation, but a meaningful difference — that's a major failure. "Solid timber" that turns out to be MDF with a veneer is a classic example.

3. The goods are substantially unfit for their normal purpose and cannot easily and within a reasonable time be made fit.

If the product simply cannot do what products of that kind are supposed to do, and the problem can't be fixed quickly, it's a major failure. "Easily" and "reasonable time" are assessed objectively. A dishwasher that won't clean dishes, and where the repair quote is six weeks away, is a strong candidate.

4. The goods are unfit for a specific purpose you told the seller about, and cannot easily and within a reasonable time be made fit for it.

This mirrors the guarantee in section 55 (fitness for disclosed purpose). If you explained your particular need — "I need a treadmill rated for 200 kg" — relied on the seller's skill or judgment, and the goods can't meet that need, and a fix isn't easy and quick, the failure is major. Unlike limb 3, the goods need only be unfit, not substantially unfit.

5. The goods are unsafe.

Safety failures are major by definition: under section 260, goods that aren't of acceptable quality because they are unsafe have a major failure. There's no separate threshold of severity to cross. If the goods create a risk of injury or property damage that a reasonable consumer wouldn't accept, the failure is major. A heater that sparks, a child's toy with a choking hazard not disclosed on the packaging, a power tool whose guard doesn't function — all major failures.

Multiple failures. Two or more failures that aren't major on their own also together form a major failure if a reasonable consumer fully acquainted with the nature and extent of them, taken as a whole, wouldn't have bought the goods (section 260(2)).

For services, section 268 of the ACL applies a parallel set of tests. A service has a major failure if a reasonable consumer fully acquainted with the nature and extent of the failure wouldn't have acquired the service; the service is substantially unfit for a purpose services of that kind are commonly supplied for, unfit for a particular purpose you made known, or not of such a nature, or quality, state or condition, that it might reasonably be expected to achieve a result you made known, and can't easily and within a reasonable time be remedied; or it creates an unsafe situation. Two or more failures that aren't major on their own are together a major failure if a reasonable consumer fully acquainted with the nature and extent of them, taken as a whole, wouldn't have acquired the service (section 268(2)).

It's worth reading these sections alongside the consumer guarantees overview to understand how the guarantee system works before the major/minor distinction even comes into play.

When this applies (and when it doesn't)

The major failure framework applies when:

• You bought goods or services from a business acting in trade or commerce, which includes most sole traders, rather than in a genuine one-off private sale.
• You acquired the goods or services as a consumer under section 3 of the ACL: the amount paid or payable was $100,000 or less, or they are of a kind ordinarily acquired for personal, domestic or household use or consumption (either is enough). For goods only, there are exclusions: goods bought to re-supply, or to use up or transform in trade or commerce in production, manufacture or repairs. Check how section 3 applies to you.
• A consumer guarantee in sections 51 to 62 of the ACL (other than sections 58 and 59(1), which run against manufacturers) has been breached — the goods or services are defective in a legally relevant way.
• The failure meets a section 260 or 268 test.

It does not apply when:

• You caused the damage. Misuse, accidents, or modifications you made aren't failures the seller is responsible for. The ACL looks at the goods as they were at the time of supply (including defects that only show up later), not damage caused afterwards.
• The failure is minor. A scratch on the back of a laptop you'll never see, a slight colour variation in fabric that doesn't affect use — these may be non-major failures. For a non-major failure that can be fixed, the seller gets the first reasonable opportunity to remedy it within a reasonable time, by repair, replacement or refund. If it refuses or doesn't do so within a reasonable time, you can have it fixed elsewhere and recover the reasonable cost, or reject the goods (subject to section 262). You generally can't insist on a refund for a minor, fixable defect if the seller offers a prompt repair. If the failure can't be remedied, you have the same choice as for a major failure.
• You knew about the problem before buying. If the defect was clearly disclosed — a clearance tag noting a dent, for example — you can't later claim on that specific defect.
• The goods were bought in a genuine one-off private sale. The guarantees apply to supplies in trade or commerce, so a one-off sale by a private individual generally isn't covered, though most sole traders selling as a business are. Buying a used car from a dealer, however, is generally covered.
• Change of mind. The major failure framework is about defects, not regret. If the goods work exactly as described and you simply don't want them anymore, no guarantee has been breached.

The line between major and non-major isn't always obvious. A single fault can be minor on its own but major in context — for example, a small electrical fault in a medical device used by someone with a health condition might well be unsafe, making it major. Context matters.

What to do today

If you believe you have a major failure on your hands, here's how to move from knowing your rights to actually exercising them.

Step 1: Identify which of the five tests applies. Work through the section 260 criteria above. Write down, in plain language, why the failure meets at least one of them. This becomes the core of your demand letter.

Step 2: Gather your evidence.

• Proof of purchase (receipt, bank statement, email confirmation, loyalty card record — any of these).
• Photos or video of the defect.
• Any communications with the seller so far.
• A note of when you first noticed the problem and what you were doing with the goods at the time.
• If the goods are unsafe, document that clearly — it's the strongest of the five tests.
• If the seller disputes the cause, a written report from an independent repairer or expert on the cause of the fault and the repair cost. It carries more weight than your own assessment.

If you paid by card, ask your card issuer now whether a chargeback is available; if you used buy now pay later, ask the provider about its dispute process; both follow the card scheme's or provider's own time limits, not the ACL's.

Step 3: Contact the business in writing. A phone call is easily forgotten or denied. An email or letter creates a record. State:

• The date and place of purchase.
• What the goods are and what they cost.
• What the failure is, described specifically.
• Which section 260 test you say is met, and why.
• That you are exercising your right under section 259 of the ACL to choose your remedy — and what remedy you are choosing (refund, replacement, or compensation).
• A reasonable deadline for their response (14 days is a common practical default, not an ACL requirement).

If drafting this feels daunting, you can generate a demand letter using fairgo. The tool identifies the relevant ACL sections automatically and produces a letter you send under your own name.

Step 4: Keep the goods. Don't throw out or return the item without written confirmation of your refund. If the matter goes to a tribunal or court, the physical evidence matters.

Step 5: Don't accept a repair if you don't want one. For a major failure with goods, the choice of remedy is yours, provided the right to reject hasn't been lost under section 262. If the seller offers a repair and you want a refund, you are entitled to say no to the repair. Politely but clearly state that you are exercising your right to a refund under the ACL.

What if the business refuses

Businesses sometimes push back — claiming the failure is minor, blaming the consumer, or simply ignoring the letter. If that happens, you have several escalation paths.

State and territory consumer bodies. Your state or territory consumer protection body may help, for example by contacting the business or conciliating, if your complaint meets its criteria. Most expect you to have tried to resolve the matter with the business first, and eligibility rules vary by state and dispute type (in the ACT, for example, statutory conciliation applies only where the remedy you seek is worth $5,000 or less). These bodies don't make binding orders in ordinary consumer disputes and can't make the business settle. Contact details are at /agencies.

A tribunal or court with jurisdiction. In NSW, Victoria, Queensland, the ACT and the NT, a tribunal (NCAT, VCAT, QCAT, ACAT or NTCAT) hears many consumer claims within its limits; in Western Australia, South Australia and Tasmania, ordinary consumer claims go to the Magistrates Court. Jurisdiction depends on each forum's enabling legislation, the type of claim and the amount, so confirm the forum and its current thresholds on the official site before filing. You can usually run a claim without a lawyer, though some forums restrict legal representation (QCAT, for example, requires permission). Check current filing fees on the official site, and ask about fee exemptions, waivers or deferrals if cost is a concern. Our guide to choosing the right tribunal or court has more.

What tribunals and courts look at. When you file, the tribunal or court will assess whether the failure meets the section 260 tests. They will look at the evidence you've gathered — photos, communications, expert reports if any — and decide whether the failure is major. "The warranty has expired" is not a defence to a consumer guarantee claim. "Our policy is no refunds" is not a defence either.

The ACCC. The Australian Competition and Consumer Commission (accc.gov.au) handles systemic conduct and industry-wide issues, not individual disputes. Reporting to the ACCC can be useful if you believe a business is systematically misleading consumers, but for your specific case, your state or territory consumer body and a tribunal or court with jurisdiction are the right places to go.

Common mistakes

Accepting "it's a minor fault" without checking. Sellers have an obvious incentive to classify every failure as minor — it gives them the first opportunity to choose how to fix it. Don't take their word for it. Work through the section 260 tests yourself.

Agreeing to a repair before asserting your rights. Once you hand the goods over for repair and accept the outcome, it can be harder to argue for a refund later. If you believe the failure is major, say so in writing before any repair happens. No special wording is needed, and accepting a repair doesn't automatically waive your rights; a failed repair can support a major-failure claim.

Confusing the manufacturer's warranty with your ACL rights. The warranty is a voluntary promise from the manufacturer. Your consumer guarantee rights run primarily against the seller and are set by law (manufacturers can have separate liability under sections 271 to 273). "Your warranty has expired" is irrelevant to a major failure claim — the ACL doesn't set a single warranty-style expiry, though timing still matters (see "Waiting too long" below). A fridge that fails after three years may still be covered if a reasonable consumer would expect it to last longer. For more on this distinction, see consumer guarantees vs warranty.

Claiming compensation that's out of proportion. If you're seeking compensation for the drop in value rather than a full refund, the amount needs to be reasonable and supportable. Tribunals are sceptical of inflated claims, and an unreasonable demand can undermine an otherwise strong case.

Not putting anything in writing. Verbal complaints are easy to deny. Every step of this process — your initial complaint, the seller's response, any offers made — should be in writing or confirmed in writing after the fact.

Waiting too long. The ACL doesn't set a single fixed warranty-style expiry for consumer guarantee claims, but timing matters. Delay can make it harder to show that the fault existed at the time of supply rather than happening afterwards. You also lose the right to reject goods if any of the four grounds in section 262 applies: the rejection period has ended (it runs from supply, not from when you noticed the fault, for as long as it would be reasonable to expect the failure to become apparent, given the type of goods, their likely use, and how long and how much they can reasonably be used); you have lost, destroyed or disposed of the goods; they were damaged after delivery for reasons unrelated to their condition when supplied; or they have been attached to or incorporated in real or personal property and can't be detached or isolated without damaging them. Deadlines for bringing a claim also apply under state and territory limitation laws and forum rules. Act promptly once you identify a failure.
