    What are the ACCC rules for health claims in advertising in Australia?

    CompliGUARD reviews this compliance area against TGA · AHPRA · FSANZ · ACCC frameworks for Australian health brands — here's what the regulations say.

    CompliGUARD reviews health claims against the ACCC-enforced Australian Consumer Law. The ACCC enforces the Australian Consumer Law prohibition on misleading and deceptive conduct — meaning any health claim in advertising must be accurate, capable of substantiation, and not likely to create a false impression about the product or service, regardless of which other regulatory framework also applies.

    The rule: Australian Consumer Law, Competition and Consumer Act 2010, Schedule 2, s.18 and s.29

    Section 18 of the Australian Consumer Law prohibits conduct in trade or commerce that is misleading or deceptive, or likely to mislead or deceive. Section 29 specifically prohibits false or misleading representations about the standard, quality, value, grade, composition, style, or model of goods or services. For health claims, the ACCC applies these provisions to any representation — express or implied — that a product or service provides a health benefit. The ACL applies independently of TGA, AHPRA, and FSANZ obligations — a claim can comply with one framework and still breach the ACL if it creates a misleading impression.

    What this means in practice

    • Every health claim must be capable of substantiation — you must hold evidence that supports the claim before making it, not after it is challenged.
    • The test is not whether the claim is literally true — it is whether a reasonable consumer would be misled or deceived by the overall impression created.
    • Implied claims are subject to the same ACL standard as express claims — imagery, testimonials, and contextual framing can create misleading health impressions without explicit health language.
    • The ACL applies to all advertising channels: websites, social media, email, packaging, in-store displays, and influencer content commissioned by the brand.
    • Substantiation must exist at the time the claim is made — you cannot commission evidence after receiving an ACCC inquiry.

    Common mistakes

    Mistake

    Assuming TGA or FSANZ compliance means ACL compliance

    Problem

    The ACL operates independently. A health claim can be within TGA Permitted Indications or on the FSANZ approved list and still breach the ACL if it creates a misleading impression in context. Regulatory framework compliance is not a defence to ACL misleading conduct.

    Fix

    Apply ACL substantiation requirements in addition to, not instead of, TGA and FSANZ framework compliance. Ask: would a reasonable consumer be misled by this claim, even if it is technically within another framework's rules?

    Mistake

    Using unqualified superlatives in health advertising

    Problem

    'The most effective', 'the best', 'the fastest' — unqualified superiority claims imply evidence that typically does not exist. These are misleading representations under ACL s.29 and are among the most commonly investigated claim types.

    Fix

    Remove unqualified superlatives. If a comparative claim is justified by evidence, qualify it precisely: 'clinically shown to reduce X by Y% vs placebo in a 12-week study' — and retain the study.

    Mistake

    Relying on disclaimers to cure misleading headline claims

    Problem

    A disclaimer does not cure a misleading headline claim — the ACCC assesses the overall impression created by advertising, including the prominence of the main claim relative to any qualification. A large headline health claim with a small-print disclaimer is still misleading if the disclaimer is not prominent enough to qualify the main claim effectively.

    Fix

    Ensure qualifications are as prominent as the claims they qualify. If a claim requires a significant qualification to be accurate, reconsider whether the claim should be used at all.

    Compliant vs non-compliant example

    ❌ NON-COMPLIANT

    Assuming TGA or FSANZ compliance means ACL compliance

    ✅ COMPLIANT

    Apply ACL substantiation requirements in addition to, not instead of, TGA and FSANZ framework compliance. Ask: would a reasonable consumer be misled by this claim, even if it is technically within another framework's rules?

    The enforcement context

    The ACCC has taken enforcement action against health supplement brands, food businesses, natural therapy practitioners, and medical device companies for misleading health claims under the ACL. Penalties for misleading conduct can reach $50 million for corporations. The ACCC accepts complaints from consumers and competitors and actively monitors health advertising across all channels.
