Deceptive And Misleading Advertising: Australian Legal Guide For Businesses

Marketing your business is exciting - it’s how you showcase your value, win customers and grow. But in Australia, your ads don’t just need to be catchy. They also need to be legally accurate and transparent.

In a crowded market, it can be tempting to push bold claims or rely on clever wording. The risk? If your promotion gives consumers the wrong impression, it can breach Australian Consumer Law and expose you to serious consequences.

In this guide, we’ll unpack what counts as deceptive or misleading advertising in Australia, explain how the Australian Consumer Law applies, share practical examples to avoid, and outline a simple compliance process you can use before your next campaign. We’ll also cover what to do if you realise an ad has crossed the line, and the key legal documents that help protect your brand.

If you’re unsure where to start or want a quick check of your website, socials and sales collateral, we’re here to help so you can keep growing with confidence.

What Counts As Deceptive Or Misleading Advertising?

Deceptive or misleading advertising is any conduct, statement or impression in your marketing that is likely to lead an ordinary consumer into error. It’s not just about what you say - it’s also about what you don’t say, the overall presentation, and the context.

You don’t need to intend to mislead. If the overall impression of your ad is likely to mislead or deceive, it may breach the law even if the wording is technically accurate or the mistake was unintentional.

This applies across channels: websites, product pages, social ads, influencer content, email campaigns, in‑store signage, packaging, and verbal representations by sales teams.

Courts and regulators look at the “overall impression” on your target audience. If your headline, imagery and qualifiers point in different directions, the prominent message usually wins. Hiding crucial conditions in fine print rarely saves an otherwise misleading headline.

How The Australian Consumer Law Applies

Australia’s key advertising rules sit in the Australian Consumer Law (ACL), a national law enforced by the ACCC and state and territory fair trading agencies.

The core “catch‑all” provision is Section 18, which prohibits conduct that is misleading or deceptive, or likely to mislead or deceive. This section does not itself carry civil penalties. Instead, it allows for remedies like injunctions, corrective notices and damages.

Separate ACL provisions prohibit specific types of false or misleading representations and these are civil penalty provisions. Common examples include Section 29 (false or misleading representations about price, quality, performance, sponsorship, approval, country of origin and more). Contraventions of these specific provisions can attract significant penalties.

Practically, many advertising matters are assessed under both: the general rule against misleading or deceptive conduct (s 18) and one or more specific false representation provisions (e.g. s 29).

Penalties And Remedies - Getting It Right Matters

If your conduct breaches a civil penalty provision (such as s 29), the maximum penalty for a corporation per contravention is the greater of $50 million; three times the benefit obtained; or, if that cannot be determined, 30% of the corporation’s adjusted turnover during the period of the breach. Individuals can also face substantial penalties.

Even where penalties don’t apply (for instance, under s 18), you may be ordered to compensate customers, offer refunds, publish corrective statements, vary or void contracts, and change your practices. The brand damage from a public enforcement outcome can be long‑lasting.

Common Examples To Watch For

Here are patterns that often get businesses into trouble - and how to think about them.

• Bait advertising: Advertising a bargain price when you only have minimal stock and no reasonable plan to meet demand.
• Drip pricing and hidden fees: Headline prices that don’t include mandatory charges, booking fees or unavoidable add‑ons until late in the checkout flow.
• “Up to” or “from” claims: “Up to 50% off” or “from $19” where only a tiny fraction of products or dates qualify, or stock is very limited.
• Comparative and superlative claims: “Best,” “#1,” “cheaper than X” or “fastest” without robust, current and like‑for‑like substantiation.
• Testimonials and social proof: Reviews that are incentivised without disclosure, curated to remove negatives so the overall impression is distorted, or that imply typical results that aren’t typical.
• Performance or results claims: “Clinically proven,” “guaranteed to save 30%,” or environmental claims like “100% recyclable” without clear, verifiable evidence.
• Country of origin: Using “Australian made” or imagery that suggests local manufacture when the key production steps occur overseas.
• Scarcity and urgency: “Only 2 left” or “sale ends in 2 hours” when those representations are automated or not accurate for the product shown.
• Pricing presentation: Sales and RRP comparisons that don’t reflect genuine previous prices, or that ignore rules around advertised price laws and RRP/MSRP disclosures.

Think about the overall impression on a reasonable member of your audience. If they’d likely take away a message you can’t substantiate, re‑work the claim or make the limitation prominent.

Puffery vs Misleading Claims - Where’s The Line?

“Puffery” is the kind of obvious exaggeration no reasonable consumer would take literally - statements like “the world’s tastiest chips” or “the ultimate gym experience”. Puffery is generally permitted.

But once a statement conveys a matter of fact or likely performance - for example, “clinically proven to reduce wrinkles in 7 days” or “20% cheaper than Competitor X every day” - you’ve shifted out of puffery. You’ll need solid, current evidence. If you can’t substantiate it, change or remove it.

Also remember the prominence rule: a bold headline with a strong claim cannot usually be cured by long‑winded qualifiers buried in fine print. Qualifiers need to be clear, nearby and consistent with the headline.

How To Keep Your Marketing Compliant

A structured approval process will help you ship campaigns with confidence. Here’s a practical, repeatable checklist you can adapt for your team.

1) Identify The Claim And Your Evidence

• For each headline or key message, ask: what is the consumer likely to take from this? Is it a factual claim?
• Gather substantiation now (data, test results, competitor audits, supplier confirmations) and record it in a central folder.
• Review third‑party inputs (influencer scripts, supplier specs) - you’re responsible for representations made on your behalf.

2) Make Pricing Crystal Clear

• Show the full price early, including unavoidable fees and taxes, and keep add‑ons optional.
• Use strike‑throughs, RRP and savings claims only where you can verify the historical price or genuine recommended price. Treat “RRP” and “MSRP” carefully and align with your internal policy on promotions and any applicable rules around RRP/MSRP claims.
• Ensure discounts are transparent in cart and consistent across channels.

3) Get The Fine Print Right (And Visible)

• Put key conditions where customers will actually see them (near the claim, same font family, clear language).
• Avoid contradictions between headline claims and qualifiers - the main message must remain accurate even after qualifiers are read.
• Use a well‑drafted Disclaimer where genuine uncertainty exists, but never to mask an otherwise misleading claim.

4) Present Terms Clearly Across Your Website

• Publish up‑to‑date Website Terms and Conditions that set out how your site and offers work, including eligibility, promotions and limitations.
• If you collect personal information (e.g. email for offers), display a compliant Privacy Policy and keep your marketing consents consistent with your policy.
• For goods, ensure any warranty wording aligns with ACL guarantees and, where applicable, use a compliant Warranties Against Defects Policy.

5) Manage Reviews, Testimonials And Influencer Content

• Don’t edit out negative reviews in a way that makes the overall impression misleading.
• Ensure sponsored or incentivised testimonials are clearly disclosed and not framed as typical results unless they are.
• Provide influencers with written guidelines and pre‑approval steps so claims remain accurate.

6) Train Your Team And Vendors

• Set an internal sign‑off process for campaigns that includes legal checks for higher‑risk claims.
• Onboard agencies, resellers and affiliates with your advertising rules and require compliance in contracts.
• Schedule periodic audits of landing pages, banners and evergreen content to keep information current.

If You’ve Crossed The Line: How To Fix A Misleading Ad

Act quickly and transparently. Early, genuine remediation can reduce consumer harm and may lessen enforcement risk.

• Pause and assess: Remove or correct the ad immediately across all channels. Screenshot and save versions for your records.
• Scope the impact: Identify who saw the ad, what was purchased and over what period. Work out whether customers are out‑of‑pocket or missed a genuine benefit.
• Offer remedies: Provide refunds, store credits, price adjustments, or re‑deliver the promised benefit where appropriate. Document outreach attempts.
• Correct the record: Publish a clear correction where the original claim appeared (e.g., a note on the product page or a follow‑up email).
• Improve your process: Update your sign‑off workflow, add an evidence register, and clarify responsibility with agencies and influencers.
• Seek advice early: If you receive a complaint or regulator enquiry, get legal help before responding so you can manage risk and craft an appropriate remedy strategy.

Industry And Channel Nuances To Consider

Beyond the ACL’s general rules, some sectors and channels carry extra advertising obligations. A few examples:

• Therapeutic goods and health claims: Medical, cosmetic and supplement claims require high‑quality substantiation and are tightly regulated. Be especially cautious with “clinically proven,” “cures,” or disease‑related claims.
• Food and drink: Health, nutrition and origin claims must be accurate. State and territory food laws also apply (for example, the Food Act 2003 (NSW) operates in New South Wales).
• Pricing and promotions: Ensure consistency with your pricing history and any applicable promotional rules (including channel‑specific constraints on marketplaces and platforms).
• Email and SMS marketing: Be clear about who you are, what you’re offering and how to opt out, and ensure consent matches your promised use of data.
• Franchising and B2B offers: If you market business opportunities or franchises, extra disclosures and codes (e.g., the Franchising Code) may apply to your representations.

Different platforms and formats (e.g., short‑form video, influencer stories, long‑form landing pages) can change how a consumer interprets a claim. Always test the overall impression in the real environment, on mobile and desktop, before launch.

Key Legal Documents That Help Protect Your Business

The right contracts and policies support compliant marketing, set expectations with customers, and reduce disputes.

• Website Terms and Conditions: Explain how your site, offers, promotions, pricing and limitations work in one place. Link these near checkout and relevant claims. Use tailored Website Terms and Conditions for clarity and consistency.
• Privacy Policy: Required if you collect personal information, and essential if you segment audiences or run email/SMS campaigns. A clear Privacy Policy builds trust and keeps your data practices transparent.
• Terms of Sale / Customer Contract: Define product descriptions, inclusions/exclusions, delivery timeframes, pricing, renewals, returns, and liability. Align promises here with your ads so the customer journey is consistent.
• Warranties Against Defects Policy: If you offer a “warranty” beyond ACL guarantees, you must include mandatory wording and key details. A compliant Warranties Against Defects Policy helps you get this right.
• Disclaimer: A targeted, well‑drafted Disclaimer can clarify variability (e.g., results may vary) and the scope of your content. It can’t fix a misleading headline, but it can reduce confusion where appropriate.
• Influencer and Affiliate Agreements: Set clear rules for claims, disclosure, approvals and take‑down rights so third‑party content stays compliant.
• Agency and Creative Agreements: Allocate responsibility for compliance, approvals, and IP ownership, and build in warranties and indemnities for misleading claims supplied by the agency or suppliers.

When these documents are aligned and up to date, your ads, landing pages and customer communications tell a consistent, accurate story - which is exactly what regulators expect and customers appreciate.

Key Takeaways

• Under the ACL, businesses must not engage in conduct that misleads or deceives, and there are specific civil penalty provisions (such as Section 29) that prohibit false representations about things like price, quality and origin.
• Section 18 itself doesn’t carry penalties, but it can lead to injunctions, corrective notices and damages, and it is often pursued alongside specific false representation provisions.
• “Puffery” is allowed, but any factual or performance claim needs solid evidence. Fine print can’t cure a misleading headline - focus on the overall impression.
• Common risk areas include bait advertising, hidden fees, comparative claims without evidence, testimonials that imply typical results, and pricing presentations that don’t reflect genuine history or advertised price laws.
• Build a simple compliance process: substantiate claims, make pricing transparent, place qualifiers prominently, and keep your Website Terms and Conditions, Privacy Policy and Disclaimer aligned with your marketing.
• If something goes wrong, act fast to correct the ad, notify affected customers and offer remedies. Early, genuine remediation can reduce harm and risk.
