section 55 ACL: the guarantee of fitness for any disclosed purpose

You walked into a store — or opened a chat window with an online retailer — and explained exactly what you needed. You told them the load you needed to carry, the surface you'd be working on, or the specific task you needed the product to perform. They pointed you to something on the shelf, said it would do the job, and you bought it. Then it didn't. That scenario is precisely what section 55 of the Australian Consumer Law was written to address.

Section 55 is one of the less-talked-about consumer guarantees, but it can be more powerful than the general acceptable-quality guarantee in section 54 — because it is tailored to your specific situation, not just what the goods are like for the average buyer.

Quick answer

Section 55 can arise in two ways: you made a particular purpose known before the goods were supplied, or the supplier represented that the goods were fit for a particular purpose. Either way, the goods then have to be reasonably fit for that purpose — and if they aren't, you have rights to a remedy under the ACL. The guarantee is displaced only if the circumstances show you didn't actually rely — or that it was unreasonable to rely — on the supplier's skill or judgment.

The strength of your position generally depends on how clearly the purpose was communicated or represented, and whether the failure is major or non-major. A major failure lets you choose the remedy — reject the goods for a refund or replacement, or keep them and seek compensation for the reduction in value — subject to the limits on when you can still reject. A non-major failure gives the supplier the first opportunity to fix the problem; if they don't within a reasonable time, you may have further options.

What the law actually says

Section 55 of the ACL guarantees that goods supplied to a consumer in trade or commerce — other than goods sold by auction, where the auctioneer acts as an agent for the seller — are reasonably fit for any purpose the consumer discloses, and for any purpose the supplier represents that they are reasonably fit for. The guarantee doesn't operate where the circumstances show the consumer did not rely, or that it was unreasonable to rely, on the supplier's skill or judgment. In practice, it's triggered two ways.

A purpose you disclosed. You make a particular purpose known — expressly or by implication — before the goods are supplied. This doesn't need to be a formal declaration. Telling a salesperson "I need a router that can handle 50 simultaneous devices in a warehouse environment" is enough. So is a written message to an online retailer asking "will this work with my existing Mac running the current OS?" The purpose can be made known to the supplier, or to a person who conducted the prior negotiations for the sale — but it must be communicated before you buy, not after.

A purpose the supplier represented. Even if you didn't spell out your own purpose, the guarantee can apply where the supplier represented that the goods were reasonably fit for a particular purpose. If a supplier tells you a paint is "suitable for exterior render" or a drive is "compatible with your model of laptop," that representation can bring section 55 into play.

Whether it was reasonable to rely — and whether you did. The guarantee is displaced if the circumstances show you did not rely on the supplier's skill or judgment, or that it was unreasonable to rely on it. If you're a professional in the field and the supplier is a general retailer with no specialist knowledge, relying on their recommendation may be less reasonable. If the supplier holds themselves out as a specialist — a trade paint supplier, a specialist audio retailer — reliance is generally more reasonable. And if you'd already decided exactly what to buy before you walked in, and the staff member's input made no difference, the circumstances may show you didn't rely on their judgment at all.

When the guarantee operates, the goods must be reasonably fit for the disclosed or represented purpose. "Reasonably fit" doesn't mean perfect — it means fit in the way a reasonable person would expect, given the price, the type of goods, and what was communicated.

Section 55 also works alongside section 54, the acceptable-quality guarantee. Section 54 asks whether the goods meet the standard a reasonable consumer would expect for that type of product generally; section 55 asks whether they meet the standard you needed. You can often run both — a product might pass section 54 (it works for most people) but fail section 55 (it doesn't do the specific job that was disclosed or represented). See section 54 and acceptable quality for how they interact. Where a suitability claim is false or misleading, it can also raise section 29; and section 56 (goods matching their description) can be relevant where goods sold by description don't match it.

When this applies (and when it doesn't)

Section 55 is most likely to apply when:

• You explained a specific use case before buying and the supplier confirmed the product would meet it — or the supplier otherwise represented that the goods were suitable for that purpose.
• You asked a specialist retailer for a recommendation for a particular task and followed their advice.
• You purchased goods online after asking the seller a direct question about compatibility or suitability and received a positive answer.
• The product works fine for general use but fails specifically at the task you described to the supplier.

Section 55 is less likely to apply when:

• You didn't disclose a particular purpose before buying, and the supplier didn't represent that the goods were fit for the purpose you're now relying on. In that case, section 54 (acceptable quality) is usually the more relevant guarantee.
• You relied on your own expertise or research rather than the supplier's recommendation. If you specified the exact product number and told the supplier you'd done your own research, it may be harder to show you relied on their skill or judgment.
• The purpose you disclosed was unusual or highly specialised, and the circumstances made it unreasonable to rely on a general retailer's assurance.
• The goods weren't acquired "as a consumer" within the meaning of section 3 of the ACL. Broadly, that covers goods that cost $100,000 or less, or goods of a kind ordinarily acquired for personal, domestic, or household use — provided they weren't acquired for re-supply or to be used up in a process of production, manufacture, or repair.
• The supplier told you before the sale they weren't in a position to advise on suitability, and you proceeded anyway — reliance may not have been reasonable.

Private sellers are generally not covered by the ACL's consumer guarantees, which apply to businesses acting in trade or commerce. Most sole traders — a freelance consultant, a personal trainer, a sole-trader retailer — will qualify as businesses even though they are individuals, because the test is whether they act in trade or commerce, not whether they are a company. A true private sale between individuals (say, a secondhand item sold on a marketplace) is a different matter.

Overseas sellers raise practical complications. The ACL can apply to some overseas sellers who supply directly to Australian consumers, but both whether it applies and whether it can be enforced across borders are complex questions. Check the position before relying on an ACL demand. For more on buying from abroad, see online purchases and the ACL.

What to do today

If you believe section 55 applies to your situation, a methodical approach gives you the best chance of a good outcome.

Step 1 — Reconstruct the communication. Gather every record of what you told the supplier and what they said in response — a chat transcript, an email thread, a screenshot of a product page, or notes from an in-store conversation. The stronger your evidence of what was communicated, the stronger your section 55 argument.

Step 2 — Document the failure. Photograph or video the problem. Note when you first noticed it, what you were trying to do, and how the goods failed to perform the disclosed purpose. Keep the goods — don't dispose of them, modify them, or return them informally without a written record.

Step 3 — Assess whether the failure is major or non-major. A major failure exists where, among other things, the goods are substantially unfit for a purpose the consumer disclosed before supply and can't easily be made fit within a reasonable time, or where a reasonable consumer wouldn't have bought them had they known about the problem. A non-major failure is one that can be remedied. This distinction matters because it determines who chooses the remedy. For a detailed explanation, see what "major failure" means under the ACL.

Step 4 — Contact the supplier in writing. Write to the supplier — email is fine — and set out:

• The date of purchase and what you bought.
• What purpose you disclosed before buying, or what the supplier represented about the goods, and what was said in response.
• How the goods have failed to meet that purpose.
• That you are relying on the consumer guarantee in section 55 of the ACL.
• The remedy you want. If the failure is major, say which remedy you're choosing — rejecting the goods for a refund or replacement, or keeping them and claiming compensation for the reduction in value. If it's non-major, ask the supplier to remedy it within a reasonable time, and say what you'll do if they don't.
• A reasonable deadline for their response — typically 14 days.

A well-drafted letter citing the relevant ACL section often resolves disputes without escalation. If you want help, fairgo can generate a demand letter for free in about 90 seconds.

Step 5 — Keep a dated record of everything. Note when you sent the letter, whether you got a response, and what was said. This record matters if you need to escalate.

What if the business refuses

If the supplier rejects your claim or doesn't respond within your stated deadline, you have several escalation options.

Your state or territory Fair Trading body offers a free conciliation service. They will contact the business on your behalf and attempt to broker a resolution. The Fair Trading body doesn't itself make binding orders in ordinary disputes and can't compel the business to participate — but many do engage, because the alternative is a tribunal. Contact details for every state and territory body are at /agencies.

A state consumer tribunal or court is the next step if conciliation doesn't resolve things. Depending on your state and the nature of the dispute, the relevant forum might be NCAT (NSW), VCAT (Victoria), QCAT (Queensland), or their equivalents elsewhere. Importantly, tribunals only have jurisdiction where their enabling legislation confers it — for many ordinary ACL disputes, the Magistrates Court or equivalent court may be the correct binding forum rather than the tribunal. You can usually appear without a lawyer, and filing fees are generally modest. Check the official site of the relevant forum for current claim thresholds and procedures before filing.

For a guide to choosing between forums, see our guide to the state consumer tribunals.

The ACCC investigates systemic conduct and industry-wide issues — it does not resolve individual disputes. Reporting to the ACCC may help if the supplier is engaging in a widespread practice, but it's not a substitute for Fair Trading conciliation or a tribunal claim for your case.

Common mistakes

Raising section 55 without evidence of the communication. The guarantee depends on what was said before the purchase. If you can't show that you disclosed the purpose (or that the supplier represented the goods as fit for it) and how they responded, the argument is much harder to run. Always try to get pre-purchase communications in writing — even a follow-up email summarising an in-store conversation can help.

Assuming any mention of purpose is enough. Section 55 requires that relying on the supplier's skill or judgment was reasonable. If you told a general hardware store employee you needed a commercial-grade industrial pump and they said "sure, this should work," relying on that advice may be questionable depending on the circumstances.

Conflating section 55 with section 54. These are separate guarantees. Section 54 is about whether the goods are of acceptable quality for their ordinary purposes; section 55 is about the specific purpose you disclosed or the supplier represented. Both may apply, but they involve different analyses. Don't assume that because the goods work for most people you have no claim — and don't assume that because the goods are defective, section 55 automatically applies.

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 the failure reflects the goods not being fit for the disclosed purpose at the time of supply, rather than something that changed later. Your right to reject may also lapse if you've kept and used the goods for a significant period. Raise the problem in writing as soon as you identify it.

Accepting a repair when you may be entitled to more. For a major failure, you choose the remedy — you can reject the goods for a refund or replacement, or keep them and seek compensation for the reduction in value. You are not required to accept a repair. For a non-major failure, the supplier chooses first, but if they don't remedy it within a reasonable time you may be able to have the item fixed elsewhere and recover reasonable costs, or in some cases reject the goods.

Confusing the consumer guarantee with the manufacturer's warranty. The section 55 guarantee is a statutory right against the seller — primarily the retailer you bought from, not the manufacturer. Manufacturers can have their own separate obligations under the ACL, including the provisions on actions against manufacturers in sections 271 and 272, but your first port of call for a section 55 claim is the business that sold you the goods. Don't let a retailer redirect you to the manufacturer as a way of avoiding their own obligations.
