The Australian Government’s Unfair Trading Practices amending legislation passed both Houses of Parliament and received assent as the Competition and Consumer Amendment (Unfair Trading Practices) Act 2026 (Act), marking one of the most significant expansions of the Australian Consumer Law (ACL) in recent years.
The Act was passed by both Houses on 2 July 2026 and will commence on 1 July 2027. The reforms introduce:
The changes are aimed at dark patterns that manipulate consumer decision making but which may fall short of the current ACL prohibitions aimed at false, misleading or deceptive conduct, with a stated policy focus on digital and subscription-based markets but a significantly broader legal and practical application. Businesses now have a fixed implementation period before the regime takes effect.
At the centre of the Act is a new, principles-based prohibition to be inserted into Chapter 2 of the ACL.
From 1 July 2027, new section 28B will prohibit a business from, in trade or commerce, engaging in conduct connected with the supply (or possible supply) of goods or services to a consumer that:
and causes or is likely to cause detriment to the consumer (which can be financial or otherwise).
We note that a contravention can occur where detriment is merely likely, consistent with the approach taken in other parts of the ACL (such as the prohibition on misleading or deceptive conduct set out in section 18, which prohibits conduct that is, or is likely to, mislead or deceive) lowering the enforcement threshold.
The prohibition is designed to capture conduct that may fall short of being misleading, deceptive or unconscionable under existing ACL provisions.
The regime is primarily focused on the protection of “consumers” adopting the transaction-based definition, meaning that a person is a “consumer” if:
As such, the Act is not a general business-to-business protection measure, as is the case with other parts of the ACL, such as the unfair contract terms regime. The financial threshold in the definition of “consumer” means that even notionally wholesale business-to-business transactions below $100,000 will be captured, even where the typical commercial leverage between the parties may be said to lie with the “consumer”.
The explanatory materials make it clear that the new prohibition is intended to directly address manipulative interface design and sales techniques, so-called “dark patterns”.
The term “dark patterns” was first coined by user experience specialist Harry Brignull on his website “Deceptive Design”, in seeking to identify user interface characteristics that steer, deceive, coerce or manipulate consumers into making choices that are often not in their best interests.
The area has been the subject of interest across consumer protection bodies internationally, and economic and regulatory agencies, including the OECD as well as Australia primarily because the practices are said to fall through the cracks of existing misleading or deceptive prohibitions.
This may include practices that:
The ACL’s existing prohibition on conduct that misleads or deceives or is likely to mislead or deceive is expansive and arguably more robust than the arrangements adopted in the United Kingdom, and the European Union, particularly given its expansion to all conduct in trade or commerce, not merely to “consumer” protections.
Where the misleading or deceptive prohibition can arguably struggle to capture the character of conduct contemplated by “dark patterns” is in relation to instances where a consumer experience may unduly limit choice, narrow options or manipulate the consumer in the manner described above but where it may be difficult to characterise any one limb of that consumer experience as misleading or deceptive.
In this sense, the focus of the reforms is on the architecture of decision-making, not simply weighing the truth or potentially misleading character of individual representations but in some senses, testing the navigability or coherence of a given field in which a consumer necessarily finds itself.
The Act also introduces a new Division 4A into the ACL, imposing specific obligations on suppliers offering subscription contracts.
Key requirements include obligations to:
Unlike the general prohibition, the subscription regime may also apply to small business subscribers, where the contract is a standard form contract and the subscriber meets the ACL small business thresholds (fewer than 100 employees or turnover of under $10 million).
To improve price transparency, the Act strengthens ACL protections against drip pricing by introducing a new obligation to disclose mandatory transaction-based charges up front.
Where a business advertises a base price it must:
These rules will apply to consumer offers and are intended to stop practices where unavoidable fees are revealed only later in the purchasing process.
Breaches of the new unfair trading, subscription and drip pricing provisions will attract civil penalties consistent with the ACL’s strengthened penalty framework.
For corporations, maximum penalties include the greater of:
Individuals may face penalties of up to $2.5 million, alongside other remedies such as injunctions, compliance orders and adverse publicity orders.
The ACCC will enforce the regime and is expected to prioritise conduct causing widespread or systemic consumer harm. The ACCC has already been cracking down on harmful sales conduct discussed in our recently published article.
Although the Act will not commence until 1 July 2027, businesses should use the transition period to prepare now by:
