Dark Patterns Under Australian Consumer Law: What's Changing and What It Means for Your Business

If your website uses countdown timers, pre-checked boxes, confusing cancellation flows, or hidden fees — you need to read this.

The Australian Government released the Competition and Consumer Amendment (Unfair Trading Practices) Bill 2026 in February 2026, proposing a general prohibition on dark patterns and unfair trading practices. Maximum penalties: $50 million per breach, three times the benefit obtained, or 30% of adjusted turnover — whichever is greatest.

Commencement date: 1 July 2027.

But businesses that wait until 2027 are already behind. The ACCC has made dark patterns its number one enforcement priority for 2026–27, and it's already using existing Australian Consumer Law provisions to take major brands to court.

Here's what you need to know.

What Are Dark Patterns?

Dark patterns are design elements in websites, apps, and digital interfaces that manipulate users into making decisions they didn't intend to make. The term was coined by UX researcher Harry Brignull in 2010.

The Australian Treasury's consultation paper defines them as practices that “distort, impair, subvert, or otherwise manipulate consumer decisions and actions, undermining consumer autonomy.”

They range from the obvious (hiding the unsubscribe button behind six clicks) to the subtle (making the “Accept All Cookies” button bright green while the “Manage Preferences” link is grey, 8pt text).

The key legal test under the new Bill: Does the practice unreasonably manipulate the consumer or unreasonably distort the environment in which they make a decision, and does it cause (or is likely to cause) detriment?

The 10 Dark Pattern Categories — and How They Map to Australian Law

International regulators and researchers have identified a taxonomy of dark patterns. Here's how each category maps to the current Australian Consumer Law and the proposed 2026 reforms.

1. Subscription Traps

What it looks like: Easy to sign up, nearly impossible to cancel. Multi-step cancellation flows, phone-only cancellation, or charging users after they've attempted to cancel.

Current ACL exposure: Sections 18 (misleading or deceptive conduct) and 21 (unconscionable conduct).

2026 Bill: Dedicated subscription contract requirements. Online sign-up must mean online cancellation. Exit steps limited to those “reasonably necessary” to end the contract. Reminder notices mandatory.

Real case: The ACCC filed proceedings against HelloFresh and Youfoodz in December 2025. HelloFresh allegedly charged 62,061 customers who had cancelled before the cut-off time. Youfoodz charged 39,408 customers in similar circumstances. Read more in our ACCC Subscription Trap Compliance guide.

2. Drip Pricing

What it looks like: Advertising a headline price, then progressively revealing mandatory fees through the checkout process — booking fees, service charges, processing fees.

Current ACL exposure: Section 18 (misleading representations about price), Section 29 (false or misleading representations).

2026 Bill: Explicit drip pricing prohibition. Any transaction-based charge must be prominently disclosed whenever a base price is displayed. Total price disclosure throughout the entire purchase journey.

Real case: JustAnswer advertised a $2 access fee. The actual cost: $50–$90 per month in recurring subscription charges — at least 25 times the advertised price. The ACCC filed proceedings in September 2025.

3. Confirm-Shaming

What it looks like: Wording opt-out choices to make users feel guilty. “No thanks, I don't want to save money” instead of a simple “No.”

Current ACL exposure: Potentially section 18 where the framing creates a misleading impression about the consequences of declining.

2026 Bill: Falls under the general prohibition on conduct that “unreasonably manipulates” consumer decision-making.

4. Misdirection

What it looks like: Using visual hierarchy, colour, size, or placement to steer users toward a more expensive option or to overlook important information.

Current ACL exposure: Section 18 — the overall impression test. Courts assess whether the total presentation is misleading, not just individual elements.

2026 Bill: Explicitly covered by the prohibition on conduct that “unreasonably distorts the environment” in which a consumer makes a decision.

Real case: Microsoft raised Microsoft 365 prices by up to 45% when adding Copilot AI features. A cheaper “Classic” plan without Copilot existed — but Microsoft only revealed it to the 2.7 million affected Australian subscribers if they initiated the cancellation process. The ACCC filed proceedings in October 2025.

5. Obstruction

What it looks like: Making undesirable actions (cancelling, downgrading, opting out) disproportionately difficult compared to desirable ones (signing up, upgrading, opting in).

Current ACL exposure: Section 21 (unconscionable conduct) — courts consider whether conditions imposed were “not reasonably necessary for the protection of the legitimate interests of the supplier.”

2026 Bill: Subscription cancellation must be available through the same channel used for sign-up. Exit steps cannot exceed what is “reasonably necessary.”

6. False Urgency and Scarcity

What it looks like: Countdown timers at checkout, “Only 2 left!” warnings, “15 people are looking at this right now” — when the urgency or scarcity is fabricated.

Current ACL exposure: Section 18 (misleading conduct), Section 29(1)(i) (false representations regarding the need for goods or services).

2026 Bill: Treasury's consultation paper specifically identifies “countdown clocks at order stage” and false scarcity notifications as target practices.

7. Forced Action

What it looks like: Requiring users to create an account, sign up for a newsletter, or enable notifications just to complete a basic task.

Current ACL exposure: Section 21 (unconscionable conduct) where the forced action is disproportionate to the transaction.

2026 Bill: Falls under the general unfair trading practices prohibition.

8. Interface Interference

What it looks like: Pre-checked consent boxes, “Accept All” buttons that are visually prominent while “Manage Settings” is hidden, or designing the UI so the more profitable option is always pre-selected.

Current ACL exposure: Section 18 — the overall impression of the interface may be misleading.

2026 Bill: Explicitly targeted. Treasury identifies “confusing menus with pre-selected checkboxes” and “omitting or obfuscating key information” as examples.

9. Sneaking

What it looks like: Adding items to a shopping cart without consent, auto-enrolling users in add-on services, or changing terms without clear notice.

Current ACL exposure: Section 18 (misleading conduct by omission), Section 29 (false representations).

2026 Bill: Covered by the general prohibition and the drip pricing provisions.

10. Social Proof Manipulation

What it looks like: Fabricated reviews, inflated star ratings, “Bestseller” tags on low-selling items, or selectively displaying only positive reviews.

Current ACL exposure: Section 18 (misleading conduct), Section 29(1)(e) (false representations about testimonials).

2026 Bill: Not specifically targeted by the new provisions, but remains firmly covered by existing ACL prohibitions.

The ACCC's 2026–27 Enforcement Priorities: Dark Patterns Are #1

On 19 February 2026, the ACCC announced its enforcement priorities for 2026–27. Four headline priority areas — and dark patterns sit at the top:

1. Manipulative and false online practices — including subscription traps, dark patterns, and practices that “manipulate consumer behaviour and unfairly impact consumer choice”
2. Misleading pricing practices (including drip pricing and illusory discounts)
3. Market power and competition concerns in digital markets
4. Consumer protection in essential services

The ACCC has already backed this up with major enforcement actions:

This isn't theoretical enforcement. It's happening now.

How Australia Compares Internationally

Australia's proposed reforms sit alongside a global crackdown on dark patterns:

European Union: The Digital Services Act (Article 25) became directly applicable across the EU on 17 February 2024. It explicitly prohibits online platforms from designing interfaces that “deceive or manipulate” users. The EU is also developing a Digital Fairness Act for broader coverage.

United States: The FTC finalised its Click-to-Cancel Rule in October 2024 (though it was vacated by the Eighth Circuit in July 2025). The FTC continues to pursue dark pattern enforcement under Section 5 of the FTC Act, including its case against Adobe for difficult subscription cancellation.

United Kingdom: The Digital Markets, Competition and Consumers Act 2024 introduced explicit drip pricing bans and broadened unfair practice definitions. Drip pricing and fake review prohibitions took effect on 6 April 2025.

The trend is clear: Every major jurisdiction is moving to explicitly prohibit dark patterns. Australia's proposed penalties — up to $50 million — are among the steepest globally.

What “Reasonable Steps” Looks Like (and Doesn't)

Here's the critical detail many businesses are missing: the exposure draft does not include a “legitimate business interests” carve-out for the general unfair trading practices prohibition.

That means you can't defend a dark pattern by arguing it was good for business. The test is whether the conduct unreasonably manipulates or distorts consumer decision-making — full stop.

So what can businesses do to prepare?

1. Audit Your Digital Interfaces Now

Don't wait for 1 July 2027. The ACCC is already prosecuting dark patterns under existing ACL provisions (sections 18 and 21). Run a systematic audit of:

• Sign-up vs. cancellation flows (are they equally easy?)
• Price display throughout the purchase journey (any hidden fees?)
• Pre-selected options and default settings
• Urgency and scarcity messaging (is it real?)
• Visual hierarchy — does design steer users toward more expensive options?
• Consent mechanisms (opt-in vs. opt-out defaults)

For a full step-by-step framework, see our Unfair Trading Practices Audit guide.

2. Document Your Compliance

When enforcement begins in earnest, businesses that can demonstrate they proactively audited and remediated will be in a materially better position — even without a formal “reasonable steps” defence.

3. Test With Real Users

Internal reviews miss what real users experience. Conduct usability testing specifically focused on:

• Can a user cancel as easily as they signed up?
• Can a user find the total price before committing?
• Are all material terms visible without scrolling, clicking, or expanding hidden sections?

4. Use Automated Scanning Tools

Manual audits are thorough but slow. AI-powered compliance scanners can systematically analyse your website's interface patterns, flag potential dark patterns, and map them to specific ACL provisions — giving you a baseline compliance report in minutes rather than weeks.

Common Questions

Do these laws apply to B2B businesses?

The general unfair trading practices prohibition applies to goods and services “ordinarily acquired for personal, domestic or household use” up to $100,000. Pure B2B transactions above this threshold are excluded — but many SaaS products serve both consumer and business markets.

My website uses countdown timers for genuine limited-time sales. Is that a dark pattern?

Real urgency isn't a dark pattern. The issue is fabricated urgency — countdown timers that reset, “limited stock” claims that aren't true, or artificial deadlines designed to prevent considered decision-making.

When do the new penalties start?

The proposed commencement date is 1 July 2027. But the ACCC is already enforcing against dark patterns under existing ACL sections 18 and 21. The new laws add explicit prohibitions and higher penalties — they don't create enforcement from scratch.

What should I do right now?

Audit your website. Identify any practices that could be considered manipulative or deceptive. Fix them. Document everything. The cheapest time to fix a dark pattern is before the ACCC sends you a letter.

The Bottom Line

Dark patterns are no longer a grey area in Australian law. The ACCC is actively prosecuting. Treasury has released draft legislation with penalties up to $50 million. And the commencement date of 1 July 2027 is closer than most compliance timelines can handle.

The businesses that act now — auditing their interfaces, fixing manipulative design patterns, and documenting their compliance efforts — will be the ones that don't end up as the next ACCC media release.
