How the Sale of Goods Acts work in Australia and where the ACL applies

If your business sells physical products in Australia, the terms of every sale are set by a quiet background law that most owners never read. When ownership of the goods passes to your customer, who is left holding the loss if a shipment is damaged, and what quality standard your goods must meet are all answered by your state's Sale of Goods Act, unless your own contract says otherwise.

These rules matter because they are the default. If your invoice, quote or checkout has not expressly dealt with a point, the Act fills the gap with a fixed outcome that may not match what you assumed. That is exactly where disputes start.

This guide explains how the state Sale of Goods Acts operate, what triggers them, and how the Australian Consumer Law (ACL) sits on top of them with a layer of rules you cannot contract out of. We finish with the common traps and where a lawyer's review pays for itself.

What the Sale of Goods Acts are, and when they bite

There is no single federal Sale of Goods Act. Instead, every state and territory has its own, and they are drafted from the same source. In New South Wales it is the Sale of Goods Act 1923 (NSW), and the other states and territories carry near-identical provisions under their own names. For practical purposes, a business operating anywhere in Australia deals with the same set of principles, and the references below are to the NSW Act as representative.

The Acts apply to a contract for the sale of goods. "Goods" means tangible, moveable things: clothing, electronics, machinery, tools, components and raw materials. The Acts do not cover the supply of pure services, although your contract and the ACL continue to regulate those separately. A mixed deal, such as selling and installing a product, splits into its goods and services parts, which is why the split matters in your drafting.

You do not need a signed document for the Acts to kick in. A sale can be formed in writing, electronically or even verbally, so an ecommerce checkout, an emailed quote accepted by return, or a handshake wholesale deal all attract the rules. What matters for a valid contract is offer, acceptance, consideration and an intention to create legal relations. Because most sales today are agreed online, the default rules have real force well before any paper changes hands.

Who is involved in the framework

The scheme primarily involves two parties: you, the seller, and your customer, the buyer. Their interests pull in opposite directions on most questions the Act answers. You want title to stay with you until you are paid and the risk of damage to transfer to the buyer as early as possible. The buyer wants the opposite, and wants the goods to arrive fit for their purpose.

Two outside actors sit over the top. A court or tribunal resolves the dispute when the contract is silent, applying the Act's default rules. And when the buyer is a "consumer" under the ACL, the regulator (the Australian Competition and Consumer Commission, or its state equivalent) and the statutory consumer guarantees constrain how far your contract can load risk onto that buyer. Understanding whose interests the Act favours by default helps you see where your own terms need to override it.

When property passes: the title rules

The central question the Acts answer is when ownership, or "property", in the goods transfers from you to the buyer. This is what decides which of you owns the goods at any moment, and it is the hinge on which several other consequences turn.

The starting principle, at s 22 of the Sale of Goods Act 1923 (NSW), is that property passes when the parties intend it to pass, judged from the terms of the contract, the conduct of the parties and the circumstances of the case. If your contract states when title transfers, that statement governs.

If your contract is silent, s 23 supplies a ladder of rules of thumb. The most important is Rule 1: where there is an unconditional contract for the sale of specific goods in a deliverable state, property passes to the buyer as soon as the contract is made, regardless of whether payment or delivery is postponed. That is a striking default. It means if you invoice a customer who promises to pay in thirty days, and the goods sit in your warehouse ready to go, title has already moved to the buyer even though they have not paid.

The other rules handle the usual complications. Where you are bound to do something to the goods to put them in a deliverable state, property does not pass until that is done and the buyer knows about it. Where you must weigh, measure or test the goods to fix the price, title waits until that is done. Goods delivered on approval or on sale-or-return terms pass title only when the buyer accepts them or keeps them past the agreed time.

Because the default is often not what a seller wants, most well-drafted terms state expressly that title passes only on full payment of the price. That phrasing overrides s 23 and keeps ownership with you until you are paid.

Risk: who carries the loss

Risk is the question of who bears the cost if the goods are lost or damaged. The Acts default ties risk to title. Under s 25 of the NSW Act, unless otherwise agreed, the goods remain at the seller's risk until property passes to the buyer, and then at the buyer's risk, whether or not delivery has happened.

The practical consequence is uncomfortable for sellers. A customer orders goods, title passes at the moment of sale under Rule 1, and the shipment is then lost in transit before delivery. Because title already passed, the buyer bears the loss. But for most retail consumers this outcome is overridden, because the ACL's consumer guarantees and the seller's practical position usually put the burden on the seller regardless.

This is where express risk terms earn their keep. A contract can decouple risk from title, and should. Common drafting states that risk transfers on delivery to the buyer's address, or on delivery to the carrier for B2B dispatches. Deciding which you want, and writing it down, prevents an argument about who claims against the carrier when a truckload goes missing. A consumer-facing approach should also reflect that, as a practical and ACL matter, you will generally send a replacement or refund if your chosen carrier loses goods, then pursue the carrier yourself.

Quality, fitness and description: the implied terms

The Acts also imply terms into every sale, even where you have written nothing. These protect the buyer and are worth knowing because they set the baseline you are held to.

The first is on title itself. Section 17 implies a condition that you have a right to sell the goods, a warranty of quiet possession, and a warranty that the goods are free from undisclosed charges or encumbrances in favour of third parties.

Then come the quality terms. By s 18, where goods are sold by description there is an implied condition that the goods correspond with the description. By s 19 there are implied conditions of merchantable quality, and of fitness for the buyer's particular purpose where the buyer relies on your skill and judgment. Section 20 does the same for goods sold by sample, requiring the bulk to match the sample and be free of hidden defects.

The notion of "merchantable quality" under these Acts is a general baseline: the goods must be of a quality a reasonable person would accept, bearing in mind the description and the price. It is not the same standard as the ACL's "acceptable quality" test discussed below, and the Acts' implied terms are excludable in a genuine business-to-business transaction with clear drafting. You cannot, however, exclude the consumer guarantees where the ACL applies, which is the crucial limit.

For a buyer who relies on your skill and judgment to supply goods for a particular purpose, s 19 will imply a condition of fitness for that purpose. If you routinely sell components that customers slot into their own machinery, an express statement about the purpose the goods are designed to serve, plus tight specifications, reduces the room for argument about whether you took on that responsibility.

Nemo dat: can you pass clean title

The Latin principle nemo dat quod non habet means no one can give better title than they hold. If you sell goods you do not own, or to which someone else has a better claim, you generally cannot pass good title to your buyer, and you will have breached the implied term under s 17.

There are established exceptions, for example a sale by a mercantile agent acting in the ordinary course of business, a sale under a voidable title before it is avoided, a sale by a seller or buyer who remains in possession of the goods after an earlier sale, sales under a court order or statutory power, and cases where the owner is estopped from denying the seller's authority. The detail is niche, and the practical lesson for a business is simpler: keep your supply chain legitimate and documented so you can pass clean title to your buyers, and make sure your own suppliers have the right to sell you the goods in the first place.

Remedies when the contract is broken

When goods do not conform, the default remedies mirror the common law of contract. A buyer may reject goods that do not match the contract, claim damages for the shortfall, or in limited cases seek specific performance. A seller whose buyer wrongfully refuses to accept or pay can sue for the price or claim damages, including losses such as storage costs where the buyer has unreasonably held up acceptance.

Your contract should allocate these processes to reflect how you actually do business, for example return authorisation steps and timeframes for claims. But any process you set must sit inside the boundaries the ACL draws for consumer sales, which we turn to now.

Where the Australian Consumer Law overlays the Acts

The ACL, found in Schedule 2 of the Competition and Consumer Act 2010 (Cth), sits on top of the sale of goods rules for most retail transactions and many B2B ones. The two regimes work together: the state Acts set the default contract framework, and the ACL imposes minimum, non-excludable standards for how you sell and support products.

The threshold question is whether your buyer is a "consumer". Under s 3 of the ACL, a buyer acquires goods as a consumer if the price paid or payable does not exceed $100,000, or the goods are of a kind ordinarily acquired for personal, domestic or household use, or the goods are a vehicle or trailer acquired for use principally in transporting goods on public roads. Note that the price threshold sits at $100,000 in the current law. This is a point worth checking, because figures quoted in older guidance, including some that circulate widely, are higher.

Exclusions then matter. A buyer is not a consumer if they acquired the goods to resupply them, or to use them up or transform them in trade or commerce in the course of production, manufacture, or the repair or treatment of other goods or fixtures. The upshot is that many ordinary small-business purchases now attract consumer guarantees because they fall under the $100,000 cap, and only buyers who are clearly resupplying or transforming goods in a commercial process fall outside.

Where the buyer is a consumer, the ACL guarantees kick in and cannot be excluded. The guarantee of acceptable quality at s 54 requires that goods are fit for the 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 informed of the goods' condition would regard as acceptable. A guarantee that goods supplied by description correspond with that description applies under s 56. Equivalent guarantees cover fitness for purpose, and the availability of repairs and spare parts. By s 64, any term that purports to exclude, restrict or modify these guarantees is void.

Two further obligations deserve a mention. Section 18 of the ACL prohibits misleading or deceptive conduct in trade or commerce, which reaches your advertising, product pages and sales scripts. Section 29 catches specific false or misleading representations about price, quality, origin, sponsorship and availability. If you grant an express warranty, it must carry the ACL-required wording. For a defective product, the ACL divides failures into minor and major, and on a major failure a consumer can choose a refund or replacement rather than being limited to a repair.

Where the common traps sit

Most disputes come from a mismatch between the defaults and what your customer expected. The traps that recur in practice are:

• Selling on credit without a retention of title clause: Title has probably already passed before you are paid, under Rule 1, and without registration your position can be lost if the buyer becomes insolvent. If you retain title until payment and want it to survive the buyer's insolvency against third parties, pair the clause with registration of a security interest on the Personal Property Securities Register (PPSR).

• Inconsistency between channels: If your website promises three-day delivery but your terms say within fourteen days, or a support agent promises a warranty your paperwork does not reflect, the customer relies on the more generous promise and the ACL treats representations as part of the deal. Keep your product pages, sales scripts, checkouts and written terms telling the same story.

• Assuming the ACL does not touch you because you sell B2B: Many B2B purchasers still come within the $100,000 consumer cap, and only buyers resupplying or transforming the goods in a commercial process fall outside. Check the exclusion before you draft limitations based on the buyer not being a consumer.

Where a lawyer's review earns its keep

A well-drafted set of terms is the difference between relying on defaults that favour the buyer and controlling title, risk and remedies yourself. A lawyer can draft the passing-of-title and risk clauses to match your payment and delivery model, add a retention of title clause supported by PPSR registration, build realistic inspection and acceptance windows into your B2B supply terms, and make sure your limitation of liability does not accidentally purport to exclude non-excludable consumer guarantees.

Because the ACL guarantees cannot be waived, and because a single inconsistency between a marketing promise and your written terms can create liability, the cheap fix is to have a lawyer reconcile your contract pack with your actual operations before a dispute forces the reconciliation to happen on someone else's terms. Doing it early is far less expensive than defending a claim about a lost shipment or an "acceptable quality" failure that your own paperwork created.

Getting title, risk and quality right saves the argument

The single point that costs a seller most in the sale of goods context is failing to say when title passes and when risk transfers, because the default answers almost always cut against the seller's interests. Title can pass before payment, and risk can sit with the buyer while the goods are still in your hands or with you while they are in the buyer's hands, depending entirely on what your contract says. Two sentences in your terms, deciding title on full payment and risk on delivery, resolve more disputes than any other drafting you are likely to add, and they cost nothing until the moment a shipment goes missing and a customer demands a refund, which is precisely when they become worth multiples of their drafting cost.

The same instinct should govern the whole contract. Decide deliberately how ownership, risk, quality and returns operate, write those decisions down consistently across your website and your terms, and check that any B2B limitations survive the ACL's consumer threshold. If you are not sure whether your current paperwork overrides the defaults in your favour, a short review of your sale terms will tell you where you are exposed, and it is usually cheaper than the first dispute.
