Interface interference · Australia
Disguised advertisement or action
Disguised advertisement or action is a working label for this design mechanism: A promotional or biased action is presented as ordinary content or as a different control, causing interaction under a mistaken understanding. This is editorial implementation guidance for Australian journeys, not a finding of unlawfulness. From 1 July 2027, a similar interface is relevant to ACL section 28B only if the complete consumer-connection, manipulation or unreasonable-distortion and actual-or-likely-detriment test is met. Current ACL rules require a separate assessment.

Definition
What is this pattern?
A promotional or biased action is presented as ordinary content or as a different control, causing interaction under a mistaken understanding. This is a design and research taxonomy for learning and evidence review, not a statutory offence label or an automatic finding that an interface is unlawful.
How it works
A promotional or biased action is presented as ordinary content or as a different control, causing interaction under a mistaken understanding. A commercial placement or control adopts the appearance of a different familiar element, so the user activates advertising, purchase or navigation while expecting another result.
Warning signs
- The element's commercial or actual function is not apparent before interaction.
- Visual or semantic cues mimic another content or control type.
- The resulting action benefits the business or advertiser.
Potential harms
- A shopper may treat commercial placement as an independent relevance judgment.
- The user activates a commercial action while reasonably expecting to close the message.

What does this look like?
These fictional examples make the design mechanism easier to recognise. They do not depict a real company and do not establish that an individual interface is unlawful.
Illustrative example 1 · Sponsored result imitates an organic recommendation
A fictional marketplace gives a paid placement the same typography and ranking treatment as organic results, with “sponsored” hidden in a tooltip.
Potential consumer harm: A shopper may treat commercial placement as an independent relevance judgment.
Illustrative example 2 · Fake close control opens another promotion
A fictional app draws an “×” in the corner of an upgrade ad, but tapping it opens the purchase page instead of dismissing the ad.
Potential consumer harm: The user activates a commercial action while reasonably expecting to close the message.
Sponsored result imitates an organic recommendation
A fictional marketplace gives a paid placement the same typography and ranking treatment as organic results, with “sponsored” hidden in a tooltip.
Top match for you. The paid placement looks identical to an organic result.. View top match. View sponsored offer
Sponsored placement. The commercial relationship is visible before the product claim and click.. View sponsored offer. View top match. Price, period and commitment, expanded: The price and material terms associated with “View sponsored offer” remain beside this choice.
Why the first version can mislead: The presentation changes what the user can notice or predict at the pricing decision. The problematic state shows: “The paid placement looks identical to an organic result.” Its influence should be tested by comparing the consequence and usability of “View top match” with “View sponsored offer”. A shopper may treat commercial placement as an independent relevance judgment.
What a fairer design does: Label advertising at first exposure and keep the commercial marker visible beside the result and action.

Fake close control opens another promotion
A fictional app draws an “×” in the corner of an upgrade ad, but tapping it opens the purchase page instead of dismissing the ad.
Limited upgrade. The familiar close symbol is wired to the upgrade route.. ×. Close promotion
Optional upgrade. Close dismisses the dialog; the upgrade button names its destination.. Close promotion. ×. What happens next, expanded: Activating “Close promotion” produces the outcome stated on the control.
Why the first version can mislead: The presentation changes what the user can notice or predict at the pricing decision. The problematic state shows: “The familiar close symbol is wired to the upgrade route.” Its influence should be tested by comparing the consequence and usability of “×” with “Close promotion”. The user activates a commercial action while reasonably expecting to close the message.
What a fairer design does: Make the close control perform only dismissal and label any purchase action separately.

Label advertising and action outcomes clearly before interaction and avoid mimicking unrelated controls or editorial content.
Legal and information status
How Australian law may apply
A promotional or biased action is presented as ordinary content or as a different control, causing interaction under a mistaken understanding. A commercial placement or control adopts the appearance of a different familiar element, so the user activates advertising, purchase or navigation while expecting another result. These harms describe a review risk, not an automatic legal conclusion. Australian section 28B commences on 1 July 2027 and requires its complete, context-specific test. Existing ACL provisions remain a separate current-law assessment.
ACL section 28B, inserted by the 2026 Act
Possible risk indicator
In pricing journeys, the disguised advertisement or action mechanism may warrant review where it manipulates a consumer or unreasonably distorts the decision environment and causes, or is likely to cause, detriment. The interface interference label and an interface similarity do not establish a contravention; the complete section 28B test, scope, facts and evidence must be applied from 1 July 2027.

Editorial analysis
The cited research sources support this working pattern within the interface interference family. It is editorial implementation guidance, not an Australian statutory category, regulator finding or legal safe harbour.
Evidence layers and open questions
Applicable law, enforcement records, policy preparation, stakeholder input, editorial analysis and unknown future details remain visibly distinct.

Existing ACLCurrent enforcement
Existing ACL provisions continue to apply on their own elements before and after commencement. The 2027 provisions must not be applied early.
Verified enforcement contextCurrent enforcement
No named pattern-specific enforcement example is asserted on this page. Existing ACL analysis remains fact-specific and separate from the 2027 provisions.
RegulationsRegulation pending
Later regulations may affect specified exclusions, matters or exceptions. That uncertainty does not postpone a core enacted rule unless the provision itself depends on prescription.
Regulator implementation materialGuidance pending
Government funding and parliamentary material anticipate regulator education and guidance. No dedicated final ACCC implementation guide is treated here as published.
Journey and evidence recommendationsEditorial implementation guidance
Label advertising and action outcomes clearly before interaction and avoid mimicking unrelated controls or editorial content. This is editorial portal guidance, not a statutory duty, regulator safe harbour or compliance certificate.

Operational review
What teams should review
- Teams
- Do “View top match” and “View sponsored offer” receive comparable prominence and explain their consequences before activation?
- Place the compared prices, billing periods and material terms on one evidence sheet; where does it support “The element's commercial or actual function is not apparent before interaction”?
- What neutral rendering or comprehension result would falsify the classification, particularly in light of “Effectively labelled advertisement distinguishable before interaction”?
- Do “×” and “Close promotion” receive comparable prominence and explain their consequences before activation?
- Can the dialog be dismissed, what action does each control trigger, and what later state confirms or contradicts “Visual or semantic cues mimic another content or control type”?
- What neutral rendering or comprehension result would falsify the classification, particularly in light of “ordinary external link with an accurate label”?
Evidence to retain
- Annotated pricing screenshots at each responsive breakpoint
- The complete state sequence before, during and after the consumer decision
- Design-system component, content, default and configuration records for the reviewed release
