A genuinely new prohibition, not a patch
On 2 July 2026, the federal Parliament passed the Competition and Consumer Amendment (Unfair Trading Practices) Bill 2026, inserting a general ban on 'unfair trading practices' into the Australian Consumer Law for the first time (Allens; DLA Piper). Until now, Australian consumer law worked by prohibiting specific bad acts — misleading conduct, unconscionable conduct — case by case. The new provision instead bans any conduct that manipulates a consumer, unreasonably distorts the environment in which they decide, or causes likely detriment, regardless of whether it also breaches an existing rule. It takes effect on 1 July 2027, giving businesses a 12-month transition window (Smart Company).
The steelman: this is closing a real gap
The case for the law is not manufactured. The ACCC has already run enforcement actions that expose the gap the old regime left open: Dendy Cinemas hid per-ticket booking fees until checkout, JustAnswer obscured that a 'trial' converted into a recurring subscription, and HelloFresh and Youfoodz customers found working sign-up flows paired with broken online cancellation, forcing a phone call to exit (Allens). In each case, the conduct plainly harmed consumers, yet none straightforwardly breached the old misleading-conduct or unconscionable-conduct provisions, which were built around discrete false statements or exploitation of a vulnerable individual, not interface design that nudges a whole population at once. A law student's honest reading of those cases is that Australian consumer law had a hole exactly where digital commerce now lives — in the design of the checkout flow itself. The ACCC has flagged 'manipulative and false practices in digital markets,' including subscription traps and dark patterns, as an enforcement priority for 2026-27, confirming this isn't a one-off statute nobody plans to use (ACCC).
Where the drafting gets specific — and defensible
The bill is more concrete than a bare ban on 'manipulation' might suggest. Drip pricing must now be disclosed 'in close proximity to the base price' before checkout, in legible and unambiguous terms — optional add-ons, surcharges, and taxes are explicitly carved out, so a restaurant offering genuine à la carte extras isn't caught (DLA Piper). Subscription cancellation must be 'easy to find' and 'straightforward,' and if sign-up happened online, cancellation must be available online too — a narrow, testable rule that maps directly onto the HelloFresh-style pattern the ACCC has already prosecuted. These provisions are the strongest part of the bill: they name the exact mechanic (hidden fee placement, sign-up/cancel asymmetry) rather than legislating a mood.
Where it gets vague — and that's the real risk
The general prohibition is a different matter. Conduct is unlawful if it 'manipulates, or is likely to manipulate' a consumer, or 'unreasonably distorts' their decision-making environment. Every persuasive design choice a legitimate business makes — a limited-time discount that is genuinely limited, a default that steers toward the seller's preferred (and often cheaper-to-service) option, a checkout that highlights the recommended plan — sits on a spectrum with the conduct the ACCC is targeting. The bill's own explanatory material leans on a non-exhaustive 'grey list' of examples (withholding material information, creating 'unreasonable pressure,' presenting information in 'complex, ineffective, unclear' formats) rather than a bright-line test, and K&L Gates notes the final version dropped the word 'unreasonable' from the manipulation limb entirely, widening it further during the bill's passage (K&L Gates). Vagueness plus a maximum penalty of the greater of $100 million, three times the benefit obtained, or 30% of turnover per contravention — with individuals exposed to penalties up to $2.5 million — is a combination that will chill more than the worst-case dark patterns (DLA Piper).
What would fix it without gutting it
The honest fix isn't to weaken the drip-pricing and subscription rules — those are working exactly as intended and should stay. It's for the ACCC to publish enforcement guidance narrowing the general prohibition to conduct that is deceptive about a material fact or that removes a choice altogether (like a broken cancel button), rather than conduct that is merely persuasive. Treasury has the year before the 1 July 2027 commencement to do this through regulatory guidance rather than litigation-by-surprise. A regulator that spends its first cases on genuinely deceptive patterns — as the pre-Act Dendy and JustAnswer matters suggest it will — builds the case law that narrows the standard for everyone else. A regulator that reaches for the general prohibition against ordinary UX choices in its first year will instead demonstrate that Australia legislated a vibe, not a rule, and invite the kind of adverse court interpretation that has hobbled similarly broad standards elsewhere. Given the ACCC's own priorities document names dark patterns as a 2026-27 focus, businesses should assume the first test cases are coming within months of commencement, not years.
