Is False Advertising Illegal In Australia? Compliance Guide For Businesses

Australian consumers are well informed and quick to compare brands. That’s great for honest businesses - but it also means your advertising needs to be clear, accurate and upfront.

So, is false advertising illegal in Australia? In short, yes. But there’s more to it than avoiding outright lies. The law also looks at the overall impression your ads create, how you present prices, the way you use reviews and endorsements, and whether key conditions are easy to find and understand.

In this guide, we’ll break down what counts as “misleading or deceptive” conduct, where penalties can apply, common pitfalls to avoid, and a practical checklist to keep your campaigns compliant under Australian Consumer Law (ACL).

What Is False Advertising?

“False advertising” is a catch-all phrase for marketing or promotional activity that gives consumers the wrong idea. Under the Australian Consumer Law (part of the Competition and Consumer Act 2010), the focus is on the overall impression your conduct, statements and visuals create - not just the fine print or your intentions.

Importantly, it doesn’t matter whether you meant to mislead. If a reasonable consumer could be misled or deceived by your ad, website, social post, email, product label, in-store display or sales pitch, there may be a breach.

• Overstating features or performance (for example, “waterproof” when it’s only splash-resistant).
• Using images that suggest a premium version when the offer is for a basic model.
• Promoting “limited time” offers that quietly continue for weeks.
• Omitting important limitations or conditions that change the deal materially.
• Suggesting endorsements or typical results that don’t reflect real customer experience.

The ACL’s general prohibition on misleading or deceptive conduct is found in section 18, which applies across all industries and marketing channels.

Is False Advertising Illegal In Australia?

Yes. The ACL makes it unlawful to engage in conduct that is misleading or deceptive, or likely to mislead or deceive. That broad rule sits alongside a set of specific prohibitions (for example, on false or misleading representations about price, quality, place of origin, or testimonials).

How Do Penalties Work?

It’s important to understand how enforcement works under the ACL:

• Section 18 (the general misleading or deceptive conduct rule) does not carry pecuniary penalties by itself, but it can lead to court orders such as injunctions, corrective notices and compensation.
• Specific false representation provisions (for example, section 29) can attract civil penalties. For companies, maximum penalties can be the greater of a fixed amount or a calculation linked to the benefit obtained or turnover, depending on the provision and when the conduct occurred.
• Regulators and courts can also impose other remedies, such as corrective advertising, compliance programs and redress for affected consumers.

In practice, the Australian Competition and Consumer Commission (ACCC) can investigate, negotiate undertakings, issue infringement notices for some contraventions, and commence proceedings for serious or systemic issues.

“But I Had Fine Print - Isn’t That Enough?”

No. Fine print can’t “cure” a misleading headline. If the main message is likely to mislead, burying the truth in conditions won’t fix it. Key qualifications and limitations need to be prominent and easy to understand.

What Counts As Misleading Or Deceptive Advertising?

Anything that creates a wrong impression can be risky. These are common scenarios that often cause trouble:

1) Exaggerated Or Unsubstantiated Claims

Performance, health, environmental or “scientific” claims need solid evidence. If you say a product is “50% more effective” or “100% natural”, you should be ready to back it up.

2) “Up To” Discounts And Was/Now Pricing

If you say “up to 60% off”, a meaningful proportion of items should be discounted at or near that rate. For “was/now” pricing, the “was” price must be genuine - not an inflated figure that was rarely or never charged. Price presentation should also comply with advertised price laws, including the single price requirement.

3) Hidden Or Late-Revealed Fees

Your single price must include any mandatory, quantifiable charges (such as GST). Optional extras don’t need to be included, but if a charge is unavoidable, it should be built into the price you display. Delivery charges can typically be shown separately where they depend on consumer selection (for example, postcode or shipping method), but the total should be clear before purchase.

4) Misleading Visuals

Images, comparisons and demonstrations should match the actual offer. Using photos of a higher-spec version or styled shots that imply accessories are included when they’re not can mislead consumers.

5) Reviews, Endorsements And Influencer Content

Customer reviews and influencer posts must be genuine and not misleading. Disclose any material connection (like free products or payment). Don’t edit or curate reviews in a way that falsely inflates a product’s reputation, and be careful when responding to or removing feedback. If you’re dealing with reputation issues, see our guide to handling fake Google reviews.

6) Green Claims And Sustainability Messaging

Terms like “eco-friendly”, “carbon neutral” or “biodegradable” need clear, accurate context and credible substantiation. Vague “green” language without specifics can be misleading.

7) Omissions And Half-Truths

You don’t need a false statement to mislead someone. Leaving out a key limitation, condition or cost that would change a customer’s decision can be just as problematic.

Pricing, Receipts And Sales Practices: Where Businesses Slip Up

Even careful teams can get tripped up by the details. Here are areas to check regularly.

Price Display And Component Pricing

Under the ACL, if a price is stated, you must present a single (total) price that includes any mandatory, quantifiable charges (such as GST). Optional extras or variable delivery costs can be shown separately until they’re known, but customers should see the true total before they commit to buy. Ensure your website, point-of-sale and ads align with advertised pricing requirements.

Discounts, Sales And Stock

“Limited time” or “only 1 left” messages must be accurate. If a promotion depends on limited stock or specific dates, state that clearly - and don’t keep the same offer running indefinitely under a countdown banner.

Receipts And Proof Of Transaction

Businesses must provide proof of transaction for sales. If the total price is $75 or more (including GST), you must provide a receipt. For lower amounts, you still need to provide proof of transaction on request. Keep records in case you need to verify a claim or process a remedy under consumer guarantees.

Email, SMS And Online Marketing

Make sure your promotional campaigns also comply with marketing and privacy rules. For example, electronic marketing must meet spam and consent standards, and your site disclosures should be consistent with your Privacy Policy and Website Terms and Conditions. If you’re running regular campaigns, it helps to revisit your email marketing laws obligations.

How To Avoid False Or Misleading Advertising: A Practical Checklist

Use this step-by-step process before, during and after each campaign.

1) Sense-Check The Headline And Overall Impression

Start with how a reasonable customer would understand the ad. Is the main message accurate without relying on fine print? If the headline creates the wrong impression, revisit it.

2) Substantiate Every Claim

Hold evidence on file for performance, health, comparative or environmental claims. If your support is uncertain or context-specific, reword the claim or add a prominent qualification.

3) Make Key Conditions Clear And Prominent

Eligibility criteria, exclusions, time limits and stock constraints should be easy to see and written in plain English. Don’t hide critical conditions behind a small “more info” link.

4) Fix Your Pricing Presentation

• Show a single (total) price that includes mandatory, quantifiable charges.
• Be careful with “was/now” and “up to” promotions - they should reflect reality.
• Make delivery costs clear before purchase when they become known.

5) Review Reviews And Influencer Relationships

Use genuine reviews that reflect typical experiences. Disclose paid or incentivised endorsements. Train your team on how to request, display and moderate reviews without creating a misleading overall impression.

6) Standardise Disclaimers (But Don’t Over-Rely On Them)

Disclaimers should clarify, not contradict. Use consistent, plain language and place them near the claim they qualify. Where appropriate, consider using a tailored Disclaimer to explain limitations, but remember that it can’t fix a misleading headline.

7) Implement Internal Checks And Training

Have a simple sign-off process for ads and web changes. Train anyone writing copy or selling to customers on ACL basics and when to escalate for legal review.

8) Keep Records And Move Fast On Corrections

Save screenshots, product specs and claim substantiation. If you spot an issue, correct it everywhere it appears (website, social, print) and consider contacting affected customers where appropriate.

9) Build Strong Website And Sales Foundations

Set up core documents that align with your marketing and sales flow. Many businesses benefit from having accurate Website Terms and Conditions, a clear Privacy Policy, and well-drafted product or service terms. These documents won’t replace honest advertising, but they support transparency and consistency across your customer journey.

Which Legal Documents Help Manage Advertising Risk?

The right documents won’t “green light” risky claims, but they do set clear expectations and help you stay consistent across channels.

• Website Terms and Conditions: Explain how your site works, key rules for use, and any limitations relevant to online sales or promotions. Align these with your actual customer journey to avoid gaps.
• Privacy Policy: If you collect personal information (for example, through checkout, account creation or newsletters), you’ll need to explain what you collect and how it’s used. Under the Privacy Act, not every small business is legally required to have one, but most online businesses use a Privacy Policy as best practice and to meet platform and customer expectations.
• Customer Terms (Online or Offline): Your sales terms should set out pricing, delivery, key conditions, and how refunds and consumer guarantees are handled. Keeping these clear supports your advertising claims.
• Disclaimers: Use targeted disclaimers to clarify limitations or assumptions for specific products, services or content. They should be concise, fair and placed where they’re needed.
• Marketing And Review Policy: Internal guidance for staff and contractors covering claims review, influencer disclosures, handling of reviews and approval workflow.

What To Do If You’ve Made A False Or Misleading Statement

It happens. The key is to act quickly and transparently.

• Correct the statement wherever it appears and make any clarifications prominent.
• Assess consumer impact and offer appropriate remedies (for example, refunds or re-supply) in line with your obligations under consumer guarantees.
• Review your processes so the same issue doesn’t recur (update checklists, templates and staff training).
• Engage with regulators promptly and cooperatively if contacted by the ACCC.
• Get legal guidance if the error was widespread, involved sensitive claims (health, environment or safety), or attracted complaints.

Key Takeaways

• False advertising is unlawful in Australia - the ACL prohibits conduct that is misleading or deceptive, or likely to mislead or deceive.
• Penalties often arise under specific false representation provisions (such as section 29), while section 18 can lead to court orders like injunctions, corrective notices and compensation.
• Fine print can’t fix a misleading headline; your primary message and overall impression must be accurate and clear.
• Price presentation must include mandatory, quantifiable charges in the single price, and discounts and “limited time” offers should reflect reality.
• Reviews, endorsements and green claims need substantiation and disclosures; curate feedback fairly and avoid cherry-picking that distorts the truth.
• Build compliance into your workflow with checks, training, accurate website terms, a clear Privacy Policy and targeted disclaimers - and move quickly to correct any errors.
