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 right and you're in the driver's seat. Get it wrong and you may accept a repair when the law actually entitled you to walk away with your money back. This guide explains what the term means, how the law defines it, and what you can do with that knowledge today.

Quick answer

A major failure under the ACL is one where the goods (or services) are so seriously defective that a reasonable consumer — knowing about the problem in advance — would not have bought them at all, or would have paid significantly less. When a major failure exists, you choose the remedy: a full refund, a like-for-like replacement, or keeping the goods and claiming compensation for the drop in value. The business does not get to decide. The definition comes from section 260 of the ACL, and it is more generous to consumers than most retailers will 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 would not have bought the goods if they had known about the problem.

This is the broadest test and the one that covers most serious defects. Ask yourself: if you had walked into the shop knowing exactly what you know now about the fault, would you have bought this item? If the honest answer is no — and a reasonable person in your shoes would also say no — 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 be made fit within a reasonable time.

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 substantially unfit for a specific purpose you told the seller about, and cannot easily be made fit within a reasonable time.

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" — and the goods can't meet that need, and a fix isn't quick, the failure is major.

5. The goods are unsafe.

Safety failures are always major. There's no 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 by definition. 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.

For services, section 268 of the ACL applies a parallel set of tests. A service has a major failure if a reasonable consumer would not have engaged the service knowing about the problem, if the service is substantially unfit for its purpose and can't be remedied quickly, or if the service creates an unsafe situation.

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 (not a private seller).
• The goods cost up to $100,000, or are of a kind ordinarily bought for personal, domestic, or household use.
• A consumer guarantee under sections 54–62 of the ACL has been breached — the goods or services are defective in a legally relevant way.
• The failure is genuinely serious, not a trivial or cosmetic imperfection.

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 covers defects that existed at or before sale, not damage that happened after.
• 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 non-major failures, the seller gets to choose the remedy: they can repair, replace, or refund. You can't insist on a refund for a minor defect if the seller offers a prompt repair.
• 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 from a private individual. Consumer guarantees don't apply to private sales. Buying a used car from a dealer, however, is fully 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.

Step 3: Write to 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 standard for most goods disputes).

If drafting this feels daunting, you can generate a demand letter in about 90 seconds 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, the physical evidence matters.

Step 5: Don't accept a repair if you don't want one. For a major failure, the choice of remedy is yours. 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 Fair Trading bodies. Every state and territory has a free conciliation service that contacts the business on your behalf. This resolves a significant proportion of disputes without going further. Full contact details are at /agencies.

State consumer tribunals. If conciliation fails, you can file at NCAT (NSW), VCAT (Victoria), QCAT (Queensland), SAT (Western Australia), SACAT (South Australia), or the equivalent in your territory. Filing fees are typically $50–$100, hearings are designed for self-represented consumers, and the process is far less formal than court. For help choosing the right tribunal, see the NCAT, VCAT, QCAT — which tribunal guide.

What tribunals look at. When you file, the tribunal 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. Tribunals hear these cases regularly. "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, Fair Trading and the tribunal are the right forums.

Common mistakes

Accepting "it's a minor fault" without checking. Sellers have an obvious incentive to classify every failure as minor — it gives them control over the remedy. 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.

Confusing the manufacturer's warranty with your ACL rights. The warranty is a voluntary promise from the manufacturer. Your consumer guarantee rights run against the seller and are set by law. "Your warranty has expired" is irrelevant to a major failure claim — the ACL doesn't have a fixed expiry date. 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. There's no fixed time limit for consumer guarantee claims in the ACL, but delay can work against you. The longer you wait, the easier it is for the seller to argue the damage happened after purchase, or that you accepted the goods in their current state. Act promptly once you identify a failure.
