On 27 March 2026, the Federal Court of Australia handed down its judgment in The Owners - Strata Plan No 87231 v 3A Composites GmbH (No 10) [2026] FCA 351 — a landmark Federal Court representative proceeding concerning allegedly defective aluminium composite panel products branded as "Alucobond PE" and "Alucobond Plus" (together, the "Alucobond Products"). The proceedings were brought on behalf of owners and tenants of Australian buildings fitted with Alucobond Products against 3A Composites GmbH (3A), the German-based manufacturer, and Halifax Vogel Group Pty Ltd (HVG), the exclusive Australian distributor of the Alucobond Products.

The Applicants alleged that the Alucobond Products were not of merchantable or acceptable quality within the meaning of s 74D of the Trade Practices Act 1974 (Cth) (TPA) and s 54 of the Australian Consumer Law (ACL) respectively, on the basis that, at the time of supply, they:

• carried a material risk of causing or contributing to the spread and severity of fire when affixed to buildings; and/or
• were not, or carried a material risk of not being, compliant with the Building Code of Australia (BCA) when installed as advertised.

The Applicants further alleged that representations made by the Respondents were misleading as to the standard, qualities, uses and benefits of the Alucobond Products, and that the Respondents had failed to provide appropriate warnings in that regard.

The Respondents' defence

In addition to denying that the Alucobond Products were not of merchantable or acceptable quality within the meaning of the TPA and the ACL, a key aspect of the Respondents' defence was that the developers of each building were not 'consumers' within the meaning of s 3 of the ACL or s 4B of the TPA, on the basis that they had, or had held themselves out as, acquiring the Alucobond Products for the purpose of:

• resupply (s 3(2)(a)(i) ACL; s 4B(1) TPA); or
• using them up or transforming them (s 3(2)(b) ACL; s 4B(1) TPA).

In advancing this 'transformation' argument, the Respondents contended that the Alucobond Products were incapable of being affixed to a building without first being processed, fabricated and combined with other materials and components to form a façade system. These processes, it was argued, amounted to a 'using up' or 'transformation' of the Alucobond Products by the façade installers at the direction of the developers.

The Federal Court's findings

The Federal Court found that the Applicants had failed to establish that the Alucobond Products were not of merchantable or acceptable quality within the meaning of s 74D TPA and s 54 ACL. Central to this conclusion was the expert evidence which demonstrated that the Alucobond Products could be used safely in accordance with the BCA. On that basis, the Applicants' contention that the Alucobond Products possessed inherent properties rendering them "dangerous" could not be sustained.

In reaching that conclusion, Anderson J made several significant findings which clarify the practical application and scope of the guarantees as to merchantable and acceptable quality under the TPA and the ACL:

• 'Transformation' requires a substantial change in the nature of the goods, not mere alteration: His Honour rejected the Respondents' 'transformation' submission principally on the basis that any "using up" or "transforming" of the Alucobond Products would have been performed by the façade installers – not the developers, who received the Alucobond Products in the form of cladding already affixed to their buildings — such that it could not be said to have been the purpose for which the developers acquired the products. His Honour further held that, in any event, "using up" or "transforming" goods within the meaning of s 3(2)(b) ACL and s 4B(1) TPA required more than mere alterations to the form or condition of the goods; rather, a more fundamental change to the nature of the goods was necessary. In particular, 'using up' requires the good to be consumed or expended, while 'transformation' demands a change so significant that the good effectively becomes something new. On the evidence, the Alucobond Products had not been transformed to the point that they were "no longer identifiable as the same individual panels" originally supplied, and accordingly no such transformation was found to have occurred.
• Knowledge attributed to the hypothetical reasonable consumer in skilled-use cases: The Federal Court identified the hypothetical "reasonable consumer" — against whose expectations, expertise and judgment acceptable quality under s 54 ACL falls to be assessed — as the professionals involved in the design, certification and construction of the relevant buildings (together, the Qualified Professionals). This distinction was critical: the relevant consumer was not an owner or tenant of a building fitted with Alucobond Products, but rather a professional participant in the construction process. Accordingly, the assessment of the reasonable consumer's expectations was necessarily informed by the knowledge, competencies and compliance responsibilities of this "reasonable Qualified Professional" — including familiarity with applicable laws, regulations and industry standards, awareness of construction materials and their associated risks, and an understanding of fire safety performance requirements. His Honour found that Qualified Professionals, acting reasonably, would not expect the Alucobond Products — or indeed any building material — to be risk-free regardless of how they were used, and would have understood that the Alucobond Products could not be safely deployed on buildings without first considering the fire safety performance requirements applicable to the particular building in question.
• Potential for misuse does not undermine merchantable or acceptable quality: Acknowledging that the consumer guarantee provisions of the TPA and the ACL do not require goods to be entirely free of risk in order to be of merchantable or acceptable quality, His Honour observed that "a hypothetical, reasonable Qualified Professional would not regard [the Alucobond Products] as not of merchantable or acceptable quality simply because their misuse by Qualified Professionals posed a risk of harm" [emphasis added]. This finding was particularly relevant in the present case given the nature and extent of any risk depended on the particular use of the Alucobond Products on any given building and not because of any inherent property in the Alucobond Products themselves.
• Lawful use is a baseline expectation: In addressing the merchantable and acceptable quality of the Alucobond Products, His Honour emphasised that 'manufacturers such as 3A are entitled to assume that the market into which they supply goods is a law-abiding one, and to the extent that the market is not law-abiding, consequences of non-compliance must fall on those who do not comply with the law rather than the manufacturer'. This observation reinforces the principle that the statutory quality guarantees are calibrated against lawful, not hypothetical unlawful, use.
• Issues with goods beyond the manufacturer's control — s 271(2) of the ACL: Although the Applicants' acceptable quality claim was ultimately unsuccessful, His Honour nevertheless considered the Respondents' defence under s 271(2) of the ACL — broadly speaking – the defence that the acceptable quality guarantee was not complied with only because of an act or omission on the part of a third party, or a cause independent of human control occurring after the goods left the manufacturer's control. This is the first Australian product liability class action judgment to consider the practical application of this defence. Drawing on the Explanatory Memorandum to the ACL, His Honour held that s 271(2) operates to "prevent the manufacturer from being held liable for a contravention of the statutory guarantee where that contravention was wholly caused by a third party". The Federal Court concluded that, had the Applicants' acceptable quality claim succeeded, the Respondents' s 271(2) defence would have been made out — in large part because the Applicants had no answer to the expert evidence demonstrating that the Alucobond Products did not suffer from an inherent defect, leaving no explanation for the observed risks beyond misuse of the products by the Qualified Professionals.

The Federal Court also rejected the Applicants' claims under s 33 ACL and s 55 TPA. While the parties agreed that no warnings had been provided as to the standard, qualities, uses and benefits of the Alucobond Products, the Court held that this failure to warn was not liable to mislead the public. In this case, the relevant class of the public was confined to Qualified Professionals, who would already have known and understood the substance of any potential warnings.

Learnings for manufacturers doing business in Australia

• The decision underscores that the reasonable expectations against which acceptable quality falls to be assessed will be shaped by the expertise of the relevant consumer cohort. Manufacturers should therefore identify their actual customers — and the level of knowledge those customers can reasonably be expected to possess — and calibrate their product literature accordingly, ensuring that the depth of technical detail, explanation and terminology is commensurate with the sophistication of the intended audience. That is the case even where goods are supplied to qualified professionals who possess a substantial degree of assumed knowledge and expertise.
• Importantly, manufacturers are not required to anticipate or guard against potential unlawful uses of their goods by consumers or third parties. Lawful conduct remains the benchmark against which manufacturers are entitled to calibrate their assumptions regarding the behaviour of participants in the supply chain.
• Where goods are supplied through intermediaries rather than directly to end-user consumers, manufacturers should carefully assess whether their direct customers qualify as “consumers” for the purposes of the ACL, or are instead re-suppliers or entities that use up or transform the goods — as such characterisation may determine the availability of consumer guarantees. While His Honour rejected the Respondents’ ‘transformation’ defence on the specific facts of this case, the argument may be available for manufacturers in industries such as construction, electronics and metals, where the processing of the supplied goods can involve changes to their condition, nature or character sufficient that they effectively become something new by the time they reach the end-user consumer. By contrast, the defence is likely to be of more limited utility in sectors such as pharmaceuticals, fast-moving consumer goods or household appliances, where goods typically reach end-user consumers in substantially the same form as supplied by the manufacturer to those intermediaries.
• The Federal Court's comments provide welcome certainty for manufacturers that they will not be held liable for damages under s 271(1) ACL where a good fails to be of acceptable quality solely due to an act or omission by a third party, or due to factors independent of human control arising after the goods have left the manufacturer.
