Comparative Advertising rules
Australian Business & ComplianceAlso: Comparative advertising · Competitor comparison advertising
Quick definition
Comparative advertising is marketing that names or references a competitor to claim your product is better, cheaper or faster. In Australia it is legal, unlike some markets, provided every comparison is accurate, substantiated and not misleading. The risk is not the comparison itself, it is making a claim you cannot back or comparing things that are not alike.
How it varies across Australia
Comparative ads that hold up share a pattern. They compare genuinely like products, on a measure that matters, with evidence ready before launch. The ones that get pulled cherry-pick a favourable angle and hope nobody asks for the working.

Comparative advertising is when you reference a competitor directly to make your product look better. In some markets this is heavily restricted. In Australia it is allowed, and it can be a powerful challenger tactic, but it sits inside the same rules as every other claim.
The core requirement is accuracy. Every comparison must be true and substantiated, and it must not create a misleading overall impression. That means comparing like with like. Pitting your premium product against a competitor's entry model, or comparing on a measure where you happen to win while implying overall superiority, is exactly the kind of cherry-picking that becomes misleading conduct.
Using a competitor's brand name or trademark in a comparison is generally fine in Australia when the comparison is honest, because the law protects truthful competition. The exposure comes from two directions. Australian Consumer Law if the comparison misleads, and defamation or injurious falsehood if you make a false statement that damages the competitor.
The practical version is simple. Name a rival only when your comparison is genuinely fair, the claim is documented, and you would be comfortable showing the working to the competitor's lawyer.
In Australia you can name your rival. You just cannot win the comparison by bending it.
How it shows up
Risk shows up wherever a comparison is favourable but not fair: different product tiers compared as equals, a single winning metric implying overall superiority, an out-of-date competitor price. The test is whether the comparison is like-for-like and whether you hold the evidence to prove it before it runs.
The Australian context
Australia permits comparative advertising more freely than some markets, which makes it a genuine option for challengers rather than a legal minefield. The constraints come from Australian Consumer Law on misleading conduct and from defamation law. The freedom is real, but so is the substantiation burden, so an Australian comparative campaign needs its evidence file built before launch.

Common questions
Is comparative advertising legal in Australia?
Yes. Unlike some markets, Australia allows you to name and compare against competitors, provided every comparison is accurate, substantiated and not misleading. The freedom comes with a real obligation to prove the claims you make.
Can I use a competitor's brand name in my ad?
Generally yes, when the comparison is honest. Australian law protects truthful competition, so referencing a competitor's name or trademark in a fair comparison is usually fine. The risk is in the accuracy of the claim, not the naming itself.
What makes a comparative ad misleading?
Comparing things that are not alike, cherry-picking a single favourable measure to imply overall superiority, or using out-of-date competitor information. Each can create a false overall impression even when individual figures are technically correct.
What are the risks if I get it wrong?
Two main ones. Misleading and deceptive conduct under Australian Consumer Law, pursued by the regulator, and defamation or injurious falsehood if a false statement damages the competitor. Both are avoidable with a substantiated, like-for-like comparison.
