A Guide To False, Misleading And Deceptive Advertising Laws

Great marketing helps you stand out. But if your ads overstep the mark, you can quickly find yourself in trouble under Australian consumer law.

In Australia, strict rules apply to statements you make about your products and services - on your website, in social media posts, emails, price tags, influencer content and even verbal sales pitches. The good news is that with a clear framework and a few practical habits, you can advertise confidently without risking fines, complaints or brand damage.

In this guide, we’ll unpack what “false, misleading or deceptive” actually means, the laws that apply, common risk areas for small businesses, and practical steps to stay compliant. If you’re selling to Australian consumers, this is essential reading before your next campaign goes live.

What Counts As False, Misleading Or Deceptive Advertising?

The starting point is simple: your advertising must tell the truth and not mislead customers about what they’re buying. That doesn’t just cover outright lies. A statement can be misleading or deceptive if it creates a wrong overall impression - even if parts of it are technically accurate.

For example, “50% off” could mislead if you quietly raised prices a week earlier, or if the discount only applies to a handful of items you didn’t reasonably have in stock. “Eco-friendly” could mislead if your claim isn’t backed by verifiable evidence about the product’s whole lifecycle.

Under the Australian Consumer Law (ACL), the general prohibition on misleading or deceptive conduct sits in Section 18. There are also specific rules for representations about price, quality, sponsorship, testimonials, country of origin and more, including Section 29 (false or misleading representations about goods or services).

Key principles to remember:

• Think about the “overall impression” your ad creates for the average consumer in your target audience.
• Fine print can’t “cure” a bold headline if the two are inconsistent.
• Silence can mislead. If you leave out a key fact a reasonable customer would rely on, that can be deceptive.
• You must be able to substantiate any claims you make - keep evidence on file.
• Disclaimers should be clear, prominent and consistent with the main message.

What Laws Apply To Advertising In Australia?

Most small businesses promoting goods or services in Australia must comply with the ACL. Several parts of the law touch advertising and promotions.

General Misleading Conduct (Section 18)

This is the broad rule that bans conduct that is misleading or deceptive (or likely to mislead or deceive). It applies to all aspects of advertising and sales, from your website copy to in-store signage and sales calls. Read more about Section 18 and how it’s applied to businesses like yours.

Specific False or Misleading Representations (Section 29)

Section 29 lists specific types of statements that can’t be false or misleading - such as price, quality, reviews, sponsorship, availability of spare parts, or benefits of a service. Many enforcement actions target Section 29 issues because they’re common in everyday marketing.

Pricing Rules

Advertised prices must be accurate, complete and not misleading. This includes total price display, surcharge transparency and avoiding “drip pricing” (revealing mandatory fees late in the checkout). Our guide to advertised price laws covers what to watch for on websites and in-store materials.

Spam and Email Marketing Rules

If you send promotional emails or SMS, you must follow the Spam Act (consent, identification, and a working unsubscribe). Make sure your CRM and opt-ins align with best practice - see our overview of email marketing laws in Australia.

Promotions, Giveaways and Competitions

Competitions and giveaways must be run fairly and in line with consumer law and state-based permit rules. Clear terms, random draws where required, and transparent prize details are key. Our guide to giveaway laws explains the essential compliance steps.

Customer Guarantees and Warranties

If you sell products or services to consumers, legally required consumer guarantees apply. If you offer a voluntary warranty, it must meet ACL wording requirements. A clear, compliant Warranties Against Defects Policy helps you advertise confidently without overpromising.

Common Risk Areas For Small Businesses

Most advertising breaches aren’t intentional - they often come from enthusiasm, shortcuts, or a lack of internal review. Here are the hot spots where things go wrong.

Pricing And “From”/“Up To” Claims

• “Up to 60% off” must reflect genuine discounts customers can access on a meaningful portion of items.
• “From $X” pricing should be available for a reasonable period and not be an extreme outlier in limited sizes or colours.
• Show the total price (including unavoidable fees) up-front to avoid drip pricing issues. If surcharges apply, disclose them prominently and transparently under the advertised price laws.

Comparative And Superlative Claims

• “Best”, “No. 1”, “Cheapest” or “Beats Competitor X” requires robust, current evidence that matches the market and timeframe your ad suggests.
• Be careful with comparisons that rely on limited tests or outdated data.

Testimonials, Reviews And Influencers

• Paid or incentivised testimonials must be genuine and clearly disclosed.
• Don’t cherry-pick only positive reviews if that creates a misleading overall impression about typical results.
• Influencers should disclose their commercial relationship, and you’re responsible for ensuring their claims are accurate and can be substantiated.

“Free”, “Bonus” And Scarcity Claims

• “Free” offers can’t be used to hide a price increase elsewhere or impose unreasonable conditions in fine print.
• “Only 2 left”, “Ends tonight” or “Limited stock” must be accurate - false scarcity pushes can be deceptive.

Fine Print And Disclaimers

• Disclaimers should clarify, not contradict, your headline claim.
• Key conditions (like minimum purchase periods, major exclusions or eligibility) must be clear and prominent.

Green Claims And Sustainability

• Terms like “sustainable”, “eco-friendly” or “carbon neutral” need specific, verifiable support. Vague language and badges can mislead.
• Consider lifecycle impacts, supply chain details and the scope of your claim (product vs packaging vs operations).

Health, Performance Or Result Claims

• “Clinically proven”, “98% success rate” or “works in 7 days” require solid evidence that matches the exact claim you’ve made.
• Avoid implying guaranteed outcomes where results vary by customer.

Data, Privacy And Retargeting

• When advertising involves personal information (like email lists, custom audiences, or remarketing), align your practices with your Privacy Policy.
• Ensure you have consent and an easy unsubscribe for email promotions under Australia’s email marketing laws.

How To Stay Compliant: A Practical Checklist

If you’re launching a new campaign or updating a site, use this checklist to keep things on track. Treat it as part of your sign-off process - just like creative review and budget approval.

1) Sense-Check The Overall Impression

Read your headline, visuals and main copy together. Would a typical customer walk away with an accurate understanding? If your fine print reframes the headline, you likely need to adjust the headline or make the conditions more prominent.

2) Substantiate Every Claim

For each claim (“faster”, “saves $200 per year”, “99% uptime”), attach the source data or test results. Keep a central evidence log so you can respond quickly if challenged. Remember, the onus is on you to prove a claim - not on a customer to disprove it.

3) Review Pricing For Transparency

Check that the total price and any mandatory charges are clearly displayed up-front, with no surprises during checkout. If you use “up to” or “from” claims, verify that they reflect a meaningful portion of items and current stock levels under the advertised price laws.

4) Fine Print That Works (Not Hides)

Move any major limitations, eligibility criteria or lock-in terms into prominent spots (not just dense footers). Aim for concise conditions that a customer can read at a glance.

5) Disclose Relationships And Incentives

Ensure influencers, affiliates and reviewers disclose paid relationships clearly and consistently. Monitor their content - you share responsibility for accuracy and disclosure.

6) Align With Core Website Documents

Your ad promises should match the commitments in your Website Terms and Conditions, refunds info and policies. If you offer a voluntary warranty, make sure your Warranties Against Defects Policy uses ACL-compliant wording and timeframes.

7) Sanity-Check Comparisons And Superlatives

If you claim “best” or “number one”, specify the basis (e.g., “by volume sold Jan-Jun 2025, third-party audited”) and keep your evidence current. Consider narrowing the claim if your data only supports a certain segment or timeframe.

8) Build An Internal Approval Workflow

Create a lightweight checklist and define who signs off: marketing lead, legal/operations, and (for major campaigns) an executive sponsor. A 24-hour pause before publication helps you spot issues with fresh eyes.

9) Set Review Dates For Evergreen Pages

Landing pages and evergreen banners can go stale. Add a calendar reminder to re-check claims quarterly or when pricing or product features change.

10) Train Your Team

Run short refreshers for marketers, sales and customer service on the ACL, especially Section 18 and Section 29. Real examples from your business make training stick.

What Happens If You Get It Wrong? Penalties And Complaints

Breach risks are real, even for small teams. Consequences range from fixing your ad to significant penalties and public undertakings.

Regulator Action And Penalties

The ACCC and state/territory consumer agencies can investigate misleading advertising. Outcomes may include infringement notices, enforceable undertakings, public corrective statements, or court proceedings. Courts can impose substantial penalties per contravention, require refunds or repairs, and order compliance programs.

Customer Complaints And Class Actions

Customers can complain directly to your business, go to their local consumer affairs body, or commence legal proceedings. Class actions are increasingly common for systemic issues (e.g., claims about “green” credentials or “was/now” pricing practices).

Reputational Damage

Even if penalties are modest, reputational damage can linger well beyond the campaign. Competitors and media tend to amplify enforcement outcomes. Prevention is far cheaper than cure.

How To Respond If You’re Challenged

• Act quickly: pause the campaign or correct the wording while you assess the issue.
• Gather evidence: collate substantiation, stock levels, and internal approval records.
• Offer remedies: where customers may have been misled, consider refunds, discounts or replacements.
• Review processes: update training and sign-off steps to prevent repeat issues.

What Legal Documents Help Keep Ads On Track?

Clear contracts and policies help your team advertise safely and set the right expectations from the start.

• Website Terms and Conditions: Set the rules for your site, how offers work online, and your customer’s responsibilities. Align your ad promises with your Website Terms and Conditions to avoid mixed messages.
• Privacy Policy: Explains how you collect and use customer data for advertising (cookies, pixels, email lists). Make sure your practices match your published Privacy Policy.
• Warranties Against Defects Policy: If you promote a warranty, use an ACL-compliant Warranties Against Defects Policy with the required wording about consumer guarantees.
• Marketing/Influencer Agreements: Set clear rules around disclosures, approval rights and claims influencers can and can’t make.
• Customer Terms: If you sell services, a clear service agreement that matches your ads helps prevent disputes about scope, results or inclusions.
• Competition/Promotion Terms: If you run giveaways, publish concise, fair terms and run draws as promised, consistent with the ACL and state permit requirements.

Not every business needs every document on day one, but most will need several of the above before running ongoing campaigns. Getting these tailored to your operations means your ads and your fine print will work together - not against each other.

FAQs: Quick Answers To Common Advertising Questions

Is it illegal to exaggerate in an ad?

Minor “puffery” that’s clearly opinion (e.g., “the tastiest burger in town”) can be okay. But if a typical customer could take your claim as a factual promise about price, quality or results, you need evidence to back it up.

Can I rely on fine print to qualify my headline?

Fine print can clarify, but it can’t contradict the headline or hide important limitations. If a condition is significant, it should be prominent and near the main claim.

Do I need to keep proof for every claim?

Yes - you must be able to substantiate your claims quickly if asked by a regulator or customer. Keep your data, test results and decision notes in a central evidence file.

Are strike-through prices risky?

They can be if the “was” price isn’t genuine (e.g., not offered for a reasonable period). Ensure your discount comparisons reflect actual pricing history and stock availability.

Do email ads follow different rules?

Your content must still be truthful under the ACL. In addition, the Spam Act requires consent, sender identification and an easy unsubscribe, so make sure your processes align with the email marketing laws.
