"False advertising" is a phrase consumers use, but it's not a single offence in Australian law. What the law actually targets is conduct in trade that creates a misleading impression — whether through an ad, a product label, a price tag, a website page, an influencer post, or a sales call. The rules sit inside the Australian Consumer Law (ACL), which is Schedule 2 to the Competition and Consumer Act 2010 (Cth), and they apply to almost every business that sells to consumers.
The rest of this article unpacks the concept:
- The two ACL provisions that do most of the work, and how they differ.
- The elements a regulator or court looks at when deciding whether conduct is misleading.
- A worked hypothetical applying those elements to a small-business campaign.
- The misconceptions that get directors and marketing teams into trouble.
- When it's worth bringing in a lawyer, and how Artificer Legal approaches the review.
The two ACL provisions that matter most
Two sections of the ACL carry most of the enforcement work in advertising matters.
The first is s 18 — the general prohibition on misleading or deceptive conduct in trade or commerce. It's drafted broadly: a person must not engage in conduct that is misleading or deceptive, or likely to mislead or deceive. There's no need to prove that the business intended to mislead anyone, and no need to show that anyone was actually deceived. The question is whether the conduct was likely to mislead an ordinary or reasonable member of the audience the conduct was directed at.
The second is s 29 — a list of specific false or misleading representations that are prohibited in connection with the supply of goods or services. These include representations about the standard, quality, value, grade, or model of goods; about testimonials; about the existence or effect of a warranty or guarantee; and about price. Section 29 is narrower than s 18 but carries pecuniary penalties for breach. Section 18 doesn't carry pecuniary penalties on its own, but it sustains private claims for loss or damage — including the right to recover compensation under s 236 of the ACL.
In practice the ACCC often runs an enforcement matter under both sections at once: s 18 captures the broad impression created by the campaign, and s 29 pins down the specific representations.
The elements a court actually looks at
When a court or the ACCC assesses whether advertising crosses the line, they tend to work through a familiar set of questions.
Who was the audience? The ad is read through the eyes of the ordinary or reasonable member of the class the ad targets — not a careful lawyer, not the most credulous reader. Ads aimed at children, vulnerable consumers, or expert buyers are judged against that audience.
What was the dominant impression? Courts look at the overall message the audience would take away — not the literal words, and not a single qualifying sentence buried in fine print. A headline that says "50% off everything" can mislead even if a footnote excludes most of the catalogue.
Was a specific representation made? If the conduct made a concrete claim — about price, performance, country of origin, endorsements, or savings — the court asks whether that claim was accurate and whether the business had reasonable grounds for it.
Was the conduct in trade or commerce? This is rarely contested for advertising — a paid campaign or a product page on a commercial website plainly qualifies.
Did the conduct cause loss? This matters for private claims under s 236, not for regulator enforcement. A consumer who paid more, bought something they wouldn't have, or lost an opportunity because of the misleading conduct can recover that loss.
Intent isn't on the list. A business that genuinely believed its claim was true can still breach s 18 if the claim turns out to be wrong and the ad was likely to mislead.
A worked hypothetical
Imagine a small skincare brand running a winter campaign on Instagram. The headline ad reads: "Our serum reduces wrinkles by 40% — clinically proven. Australian made." A paid creator posts a video using the product without disclosing the arrangement, and the website shows a strike-through "was $120, now $60" price.
Work through the same questions a regulator would:
- Audience. Consumers shopping for skincare, many of whom won't read past the headline.
- Dominant impression. A clinically substantiated 40% wrinkle reduction, an Australian-made product, and a half-price sale.
- Specific representations. Three of them — a performance claim, a country-of-origin claim, and a savings claim.
- Substantiation. The "clinically proven 40%" claim needs a real study with a comparable population and methodology. If the only data is an in-house user survey, the headline misrepresents the evidence. The country-of-origin "safe harbour" requires the product to be substantially transformed in Australia and at least 50% of production costs to be incurred here — bottling imported product in Sydney doesn't qualify. The "was $120" needs to be a genuine, recent selling price for a reasonable period, not a sticker price the product never sold at.
- Influencer. A paid or gifted creator who doesn't disclose the commercial relationship is creating a misleading impression about independence. The brand is responsible for claims the creator makes about its product.
Each element on its own could be a breach. Run together in the same campaign, they describe the typical fact pattern in ACCC enforcement against advertising conduct.
Common misconceptions
A few recurring beliefs cause most of the trouble.
"We didn't mean to mislead anyone." Intent is irrelevant for s 18. Honest belief in the claim doesn't save the conduct.
"The fine print clarifies the offer." Fine print can qualify a claim, but it can't contradict the dominant impression of the headline. If the headline says "free", a footnote stating "$9.95 delivery applies" won't fix it if the delivery is essentially unavoidable.
"It's only puffery." Obvious exaggeration ("the best coffee in town") generally isn't actionable because no reasonable consumer would treat it as a measurable claim. But once the language becomes specific — "lowest prices guaranteed", "lasts 10 times longer" — it becomes a representation that needs evidence.
"Influencer content isn't our problem." The advertiser is responsible for claims made on its behalf. The fact that a creator posted independently doesn't insulate the brand if the brand paid, gifted, or directed the content.
"The competitor does it, so it must be fine." Industry practice isn't a defence. The ACCC frequently picks one operator out of a category and uses the matter to set the standard for the rest.
"Once we take the ad down, the risk is gone." Removing the ad helps, but doesn't extinguish a regulator's interest, and doesn't cure loss already suffered by consumers who relied on the campaign. Corrective advertising, refunds, and undertakings are typical remedies even after the offending ad is pulled.
When to bring in Artificer Legal
Most advertising compliance work pays for itself by catching a problem before it becomes a regulator matter or a class of refund claims. Lawyers add the most value at a few specific points.
Before a major campaign. A pre-launch review walks through every concrete claim — performance, comparison, price, sustainability, origin, endorsement — and tests it against the substantiation file. We flag claims that need rewording, qualifiers that need to move out of the footer, and creator briefs that need disclosure language built in.
When a regulator makes contact. A substantiation notice from the ACCC, or a letter from a state fair-trading body, has tight deadlines. The response shapes whether the matter ends with informal resolution, an enforceable undertaking, or court proceedings. Getting the tone, the scope, and the supporting evidence right matters from the first reply.
When a competitor or customer threatens action. Private claims for misleading conduct can come from a customer who relied on a representation, or from a competitor who alleges market damage. Both routes need a triage of the specific representations, the evidence, the loss claimed, and the realistic remedy.
When something has already gone wrong. If a campaign turns out to be inaccurate, the question becomes how to correct it cleanly — pull, replace, notify, refund, document — without making the position worse. Quick, documented action reduces both regulator and litigation risk.
Artificer Legal works with the marketing team, not around them. A typical engagement runs as a checklist review of the campaign brief, a clause-by-clause read of the substantiation file, a short list of edits with reasons, and a sign-off note that records what was reviewed and on what basis.
The test is the impression left on the audience
The ACL doesn't ask whether a claim is technically true. It asks what impression the audience is left with.
A literally accurate sentence buried under a misleading headline still breaches s 18. A footnote that contradicts the main message doesn't save the ad. An influencer post that omits the commercial relationship misleads even if every product claim is correct. The dominant impression is the test, and every other detail — the small print, the disclaimers, the carve-outs — only matters to the extent it changes that impression for a reasonable member of the audience.
In summary: false advertising in Australia is governed by the ACL, principally s 18 (misleading or deceptive conduct) and s 29 (specific false representations), with private remedies available under s 236 and regulator enforcement led by the ACCC. Intent isn't required, fine print can't rescue a misleading headline, and the business stays responsible for what creators, affiliates, and resellers say on its behalf. Concrete claims need concrete evidence held before publication; vague superlatives need to be either backed up or softened; and price, origin, sustainability, and endorsement representations attract particular regulator attention. A pre-launch review, a current substantiation file, and a fast, documented response when something slips are the three habits that keep most businesses on the right side of the line.
