Warranties Against Defects vs Consumer Guarantees in Australia

A warranty against defects is a voluntary extra promise a business or manufacturer chooses to make; the consumer guarantees in the Australian Consumer Law are automatic statutory rights that exist whether or not any warranty is offered, and a warranty can never replace or reduce them.

This article addresses the difference between a voluntary warranty against defects under section 102 of the ACL and the automatic consumer guarantees under sections 51 to 62. For the guarantees themselves, see consumer guarantees in Australia.

Two different things that share the word "warranty"

Shoppers often use "warranty" loosely to mean any promise a seller or manufacturer makes about fixing a problem, but the ACL treats two very different concepts under that umbrella. The first is the set of automatic, statutory consumer guarantees described throughout this cluster, which exist by force of law the moment a business supplies goods or services to a consumer, regardless of what any paperwork says. The second is a warranty against defects, sometimes called a manufacturer's warranty or an extended warranty, which is a voluntary commercial promise a business chooses to make. Confusing the two leads to the most common misunderstanding in consumer disputes: a shopper assuming that once a manufacturer's warranty period ends, they have no further rights. That assumption is usually wrong.

What a warranty against defects legally is

Section 102(3) defines a warranty against defects as a representation communicated to a consumer, in connection with the supply of goods or services and at or about the time of supply, that a person will, unconditionally or on stated conditions, repair or replace the goods (or part of them), provide the services again or rectify them (or part of them), or wholly or partly recompense the consumer, if the goods or services turn out to be defective. This definition covers both a formal printed warranty card or booklet and any document that evidences such a representation. Because it is a representation the business chooses to make, its scope, length and conditions are set by the business itself, subject to the requirements described below, not by the ACL.

The mandatory form and content rules

Section 102(1) allows regulations made under the ACL to prescribe requirements for the form and content of a warranty against defects document, such as mandating that it disclose the consumer's other rights. Section 102(2) then makes it a contravention for a business, in connection with supplying goods or services to a consumer, to give the consumer a document evidencing a warranty against defects that does not meet those prescribed requirements, or to represent directly to a consumer that goods or services carry such a warranty when they do not. The exact wording those regulations currently prescribe is set out in the regulations themselves, not reproduced verbatim in the ACL's own text, so this guide does not quote it; a business preparing a warranty document should check the current regulations directly, or seek advice, rather than rely on a general description like this one.

Penalties for a non-compliant warranty document

Section 224(3) item 9 sets the maximum penalty for contravening section 102(2) at $50,000 for a body corporate and $10,000 for an individual. This sits well below the penalties for the ACL's most serious contravention categories, such as unfair contract terms or unconscionable conduct, which can reach $100,000,000 for a corporation. The lower figure reflects that a warranty document defect is a disclosure and format failure, not a failure to actually meet a substantive consumer right.

Why a warranty can never take away your guarantee rights

Because the consumer guarantees under sections 51 to 62 exist independently of any warranty, and because section 64 makes void any contract term that purports to exclude, restrict or modify a consumer guarantee, a warranty against defects cannot lawfully be used to reduce or replace those guarantees. A business cannot tell a consumer that once a 12-month manufacturer's warranty has expired, the consumer has "no further rights"; if the product's fault would otherwise breach a guarantee such as acceptable quality under section 54, the consumer may still be entitled to a remedy under sections 259 to 263, regardless of the warranty period, subject to the rejection-period rules in section 262. Whether a guarantee is still available for goods well past a warranty's stated term often depends on how long a reasonable consumer would expect goods of that type, price and nature to last, which is exactly the durability element built into section 54(2)(e). See faulty goods and your right to a refund for that framework.

Extended warranties sold at the point of sale

Retailers commonly offer to sell an extended warranty at checkout, on top of the free warranty a manufacturer may already provide. Because the statutory guarantees already exist for as long as it is reasonable to expect goods of that kind to remain of acceptable quality, an extended warranty's genuine value depends heavily on how it compares to those existing rights, which do not require any extra payment. The ACCC has previously raised concerns about extended warranties being sold where they add little beyond existing statutory guarantee coverage; a consumer considering one should weigh what it actually adds against the guarantee protection they already have for free.

Express warranties are a third, related concept

A third concept, distinct again from both the statutory guarantees and a warranty against defects, is the express warranty guarantee in section 59. Section 59(1) guarantees that the manufacturer of goods will comply with any express warranty the manufacturer itself gives or makes about the goods, and section 59(2) separately guarantees that the supplier will comply with any express warranty the supplier gives or makes. An express warranty in this sense is simply a specific promise made about the goods, for example a claim printed on packaging that a knife blade will stay sharp for ten years. Where that kind of promise is not honoured, section 59 gives the consumer a guarantee-based right to a remedy, treated the same way as any other guarantee breach under the sections 259 to 263 framework described in faulty goods and your right to a refund, rather than as a breach of a separate, standalone warranty against defects document.

Repairers have their own disclosure duty

A related but separate obligation sits in section 103. Where a repairer accepts goods from a consumer for the purpose of repairing them, section 103(2) requires the repairer to give the consumer a notice that complies with requirements prescribed by regulation, commonly used to warn a consumer that repairing an electronic device, such as a phone or computer, may result in the loss of stored data, or that refurbished parts may be used in the repair. This obligation applies to the repairer carrying out the work, which is not always the same business that sold the goods or issued any warranty against defects, and a failure to give the required notice is itself a separate contravention of the ACL under section 224, distinct from any warranty document requirement under section 102.
