Consumer Guarantees & Unfair Contract Terms
Consumer Guarantees & Unfair Contract Terms is Week 11 of Monash University LAW5002 Principles of Contract Law A, the statutory overlay on the common law of contractual terms. It is governed by the Australian Consumer Law (the ACL — Schedule 2 to the Competition and Consumer Act 2010 (Cth)), which does two things: it implies non-excludable consumer guarantees into supplies of goods and services (ACL Part 3-2), and it makes an unfair term in a standard-form consumer or small business contract void (ACL Part 2-3). Both regimes override the parties' private bargain, and both are examinable in the IRAC-style final.
What this chapter covers
- 011. How the ACL fits over the common law — even a validly incorporated term can be overridden by statute (Competition and Consumer Act 2010 (Cth), Schedule 2)
- 022. Who is a 'consumer' — the ACL s 3 gateway: price not exceeding $100,000, OR goods/services ordinarily acquired for personal, domestic or household use, OR certain vehicles
- 033. Guarantees for goods — acceptable quality (s 54), fitness for a disclosed purpose (s 55) and correspondence with description (s 56)
- 044. Guarantees for services — due care and skill (s 60), fitness for a particular purpose (s 61) and supply within a reasonable time (s 62)
- 055. Non-excludability — a term excluding a consumer guarantee is void (ss 64, 276), with narrow carve-outs (s 64A; recreational services under CCA s 139A)
- 066. Remedies and the major-versus-minor failure switch — goods ss 259-266, services ss 267-270
- 077. Unfair contract terms — the gateway of a standard-form (s 27) consumer (s 23(3)) or small business (ss 23(4)-(5)) contract, and the effect that an unfair term is void (s 23)
- 088. The three-limb unfairness test (s 24): significant imbalance, not reasonably necessary (presumed under s 24(4)), and detriment — plus excluded terms (s 26) and the grey list (s 25)
Consumer guarantees defeat an exclusion clause on a defective laptop
- +1Issue: is Marcus a 'consumer' whose ACL guarantees apply, does the exclusion clause defeat them, and what remedy follows?
- +2Consumer gateway — ACL s 3: a person acquires as a consumer if the price does not exceed $100,000 OR the goods are of a kind ordinarily acquired for personal, domestic or household use. Marcus paid $2,900 (under $100,000) and a laptop for personal study is ordinarily acquired for household use, so he is a consumer on either limb.
- +2Goods guarantees — the laptop must be of acceptable quality (s 54): fit for common purposes, free from defects, safe and durable, as a reasonable consumer fully acquainted with its condition would accept. Blacking out and a swelling battery two weeks in breach s 54 (and raise a safety concern); if Marcus disclosed a particular purpose and relied on TechBarn, s 55 (fitness for disclosed purpose) is also engaged.
- +2The exclusion clause: a term that purports to exclude, restrict or modify a consumer guarantee is void (ss 64, 276). The "sold as is / all guarantees excluded" wording therefore does not work against a consumer, whatever Marcus signed.
- +2Remedy — major versus minor failure: an unsafe, swelling battery is likely a major failure (goods a reasonable consumer would not have acquired, and a safety issue). For a major failure the consumer chooses the remedy under ss 259-263 — reject the goods for a refund or replacement (plus damages for reasonably foreseeable loss) — rather than being forced to accept TechBarn's slow repair.
- +1Conclusion: Marcus is a consumer, the exclusion clause is void, and the defect is likely a major failure, so he may reject the laptop and demand a refund or replacement, not merely wait for a repair.
Key terms
- Australian Consumer Law (ACL)
- Schedule 2 to the Competition and Consumer Act 2010 (Cth). A national consumer-protection statute that overlays the common law of contract, including the consumer guarantees regime (Part 3-2) and the unfair contract terms regime (Part 2-3).
- Consumer (ACL s 3)
- A person (including a corporation) acquires goods or services as a consumer if the amount paid or payable does not exceed the prescribed threshold of $100,000 (current from 1 July 2021; formerly $40,000), OR the goods or services are of a kind ordinarily acquired for personal, domestic or household use or consumption, OR they are certain vehicles or trailers. Not a consumer where goods are acquired for re-supply or to be used up or transformed in a business process.
- Acceptable quality (ACL s 54)
- A guarantee that goods supplied to a consumer are as fit for all purposes for which goods of that kind are commonly supplied, acceptable in appearance and finish, free from defects, safe and durable, as a reasonable consumer fully acquainted with their state and condition would regard as acceptable, having regard to matters such as price and any statements on the packaging.
- Fitness for purpose (ACL ss 55, 61)
- Where a consumer makes known a particular purpose (or desired result) and relies on the supplier's skill or judgment, the goods (s 55) or services and any resulting product (s 61) must be reasonably fit for that purpose.
- Due care and skill (ACL s 60)
- A guarantee that services supplied to a consumer are rendered with due care and skill — the competence expected of a reasonable supplier of those services.
- No contracting out (ACL ss 64, 276)
- A term that purports to exclude, restrict or modify a consumer guarantee, or liability for its breach, is void. Section 64A allows a supplier of goods or services not ordinarily acquired for personal/domestic/household use to limit liability where it is fair and reasonable, and CCA s 139A permits a limited carve-out for death or personal injury from recreational services.
- Major failure
- Broadly, a failure a reasonable consumer would not have accepted had they known of it, or one that makes goods unsafe or substantially unfit. For a major failure the consumer chooses the remedy — reject for a refund or replacement, plus damages for reasonably foreseeable loss (goods ss 259-263) — whereas for a minor failure the supplier may elect to repair, replace or refund.
- Unfair contract term (ACL ss 23-24)
- A term in a standard-form (s 27) consumer (s 23(3)) or small business (ss 23(4)-(5)) contract is void if it is unfair. Under s 24(1) a term is unfair only if all three limbs are met: it causes a significant imbalance in the parties' rights and obligations; it is not reasonably necessary to protect the advantaged party's legitimate interests (presumed unless proven, s 24(4)); and it would cause detriment if applied or relied on. Terms defining the main subject matter or setting the upfront price are excluded (s 26).
Consumer Guarantees & Unfair Contract Terms FAQ
Can a business exclude the consumer guarantees with an 'all warranties excluded' clause?
No. Against a consumer, a term that purports to exclude, restrict or modify a consumer guarantee is void under ACL ss 64 and 276, so an 'as is' or 'all warranties excluded' clause simply does not work. The guarantees of acceptable quality (s 54), fitness for a disclosed purpose (s 55) and, for services, due care and skill (s 60) attach automatically once the buyer is a consumer under s 3. There are only narrow exceptions: a supplier of goods or services not ordinarily acquired for personal, domestic or household use may limit liability where it is fair and reasonable (s 64A), and recreational services have a limited carve-out for death or personal injury (CCA s 139A).
What makes a contract term 'unfair' and therefore void?
Under ACL s 24(1) a term in a standard-form consumer or small business contract is unfair only if all three limbs are met: it would cause a significant imbalance in the parties' rights and obligations; it is not reasonably necessary to protect the legitimate interests of the party advantaged (which is presumed unless that party proves otherwise, s 24(4)); and it would cause detriment, financial or otherwise, if applied or relied on. The court also considers how transparent the term is and the contract as a whole (s 24(2)-(3)). An unfair term is void (s 23), while the rest of the contract continues if it can operate without it. Terms defining the main subject matter or the upfront price are excluded from review (s 26), though a term allowing a later unilateral price change is not the upfront price and can be assessed.
Can AI help me with Consumer Guarantees and Unfair Contract Terms in LAW5002?
Yes, as a study aid. An AI tutor like Sia can explain the ACL section numbers, walk through the s 3 consumer gateway, the goods and services guarantees and the three-limb s 24 unfairness test step by step, and take you through worked IRAC problems so you understand why an answer is right — it will not write your assignment or sit your exam for you, and cannot promise a particular mark or a pass. The most recent past exam was an open-book electronic exam that did not permit generative AI in the exam room, so use AI to build understanding beforehand and confirm the current rules and format on Moodle.

Exam move
Treat the ACL as two separate ladders you can run on autopilot, and always reach it last in a terms problem because it is usually the strongest route. For consumer guarantees, open every problem at the s 3 gateway — is the acquirer a consumer because the price is $100,000 or less, or because the goods or services are ordinarily acquired for personal, domestic or household use? Then match each defect to a specific guarantee (goods: acceptable quality s 54, fitness for a disclosed purpose s 55, description s 56; services: due care and skill s 60, fitness s 61, reasonable time s 62), state expressly that any exclusion clause is void (ss 64, 276), and finish with the remedy, using the major-versus-minor failure switch (ss 259-270). For unfair contract terms, prove the gateway of a standard-form (s 27) consumer or small business contract (s 23(3)-(5)), screen out excluded terms under s 26 (remembering that a later unilateral price change is not the upfront price), then work all three limbs of s 24 using the s 24(4) presumption and the s 25 grey list, and conclude that an unfair term is void under s 23. Practise on short fact scenarios in IRAC, naming the section for every step and arguing both sides before you conclude, because the problem-question marking rewards identifying the source of each principle.
