Friends of Nyah Vinifera Park Inc v Minister for Environment and Water

This case arose from a challenge to a Commonwealth environmental approval for the Nyah Floodplain Restoration Project in Victoria. The project was one of the Victorian Murray Floodplain Restoration Projects and involved the construction and operation of water regulating structures to facilitate managed inundation of parts of the Nyah floodplain. In practical terms, the project was designed to restore a more natural flooding regime in an area where river regulation and changed hydrology had altered ecological conditions over time.

The dispute was not a private commercial claim between two trading businesses. It was a public law challenge brought by Friends of Nyah Vinifera Park Inc against the Minister for Environment and Water. Lower Murray Urban and Rural Water Corporation, the project proponent, was also a respondent. The commercial and regulatory significance lies in the kind of project involved: a major environmental works project requiring layered assessment, technical evidence, and a Commonwealth approval under the EPBC Act.

The central tension in the case was straightforward but important. The project’s construction phase would destroy areas of habitat critical to the survival of the Regent Parrot, a listed threatened species in the vulnerable category under the EPBC Act. Despite that, the delegate approved the project on the basis that it was likely to produce offsetting environmental benefits through the delivery of environmental water to other breeding habitat in the Nyah floodplain. Conditions of approval required an offset management plan to compensate for residual significant impacts on the Regent Parrot.

That made the case a useful example of how environmental approvals often work in practice. The legal system does not assume that every project with environmental harm must be refused. Instead, the statute may permit approval where impacts are assessed, conditions are imposed, and the decision-maker concludes that the project can proceed within the legal framework. The applicant’s task was therefore not simply to show that the project had downsides. It had to show that the approval decision was legally flawed.

The judgment sets out a staged approval history. On 2 June 2020, the proponent referred the project to the Minister under s 68 of the EPBC Act for a controlled action decision. The referral described the project as aiming to restore a more natural inundation regime across high ecological value Murray River floodplain within the Nyah Vinifera Park. It involved five regulators, containment banks, block banks, spillways, hardstand, and the decommissioning of redundant structures in Parnee Malloo Creek to allow a more natural and unhindered flow.

The referral also described the ecological setting. It explained that the natural pre-regulation hydrology of the Murray River had been altered, that flood durations had declined, and that the forests and woodlands of the floodplain had been declining in condition over recent decades. The referral identified the Regent Parrot as a listed threatened species within the construction footprint and inundation area. It also stated that environmental watering was recognised as important in supporting River Red Gum habitat and breeding sites for the species.

On 26 June 2020, a delegate decided under s 75 of the EPBC Act that the project was a controlled action, with ss 18 and 18A, dealing with listed threatened species and communities, identified as the controlling provisions. On 20 July 2020, a delegate decided under s 87 that the project would be assessed through an accredited Victorian process under the Environment Effects Act 1978 (Vic).

The proposal later changed. On 18 November 2022, after a request from the proponent, a delegate accepted a variation of the proposed action under s 156B of the EPBC Act. The varied proposal remained substantially the same in concept, but the construction footprint increased to about 10.16 hectares, resulting in the loss of up to 14.1 hectares of native vegetation. The maximum inundation area was reduced slightly to 475 hectares. The extract says there was no material change in the predicted impacts of the varied proposal for the Regent Parrot.

The Victorian assessment process also mattered. A Standing Inquiry and Advisory Committee report published in July 2023 concluded that the project should have a net community benefit with positive ecological impacts due to increased flooding, but that implementation, management and monitoring would need to be undertaken carefully and thoroughly to minimise risk. In October 2023, the Victorian Minister’s assessment report stated that although the projects would give rise to significant adverse environmental effects during construction, they could proceed with acceptable effects and achieve an overall improvement to biodiversity in the long term, subject to further analysis and careful management. Those materials were part of the broader assessment record before the Commonwealth delegate.

The applicant’s case was not simply that the project was environmentally undesirable. The extract identifies two main contentions, both directed to legal error in the approval decision.

First, the applicant argued that the environmental benefits under the proponent’s offset strategy were highly uncertain. The extract says there was said to be an accepted risk of incorrect or prolonged inundation events that would be adverse to suitable habitat for the Regent Parrot. On that basis, the applicant alleged that by relying on an inadequate offset to justify the destruction of critical habitat, the delegate failed properly to consider the impacts of the project, failed to consider the principles of ecologically sustainable development and the precautionary principle, or otherwise made a decision that was legally unreasonable.

Second, the applicant argued that the delegate failed to identify and consider the relevant counterfactual. The argument was that if the project did not proceed, the State of Victoria might still need to take different measures or pursue alternative projects to achieve environmental outcomes under the Basin Plan. If those alternatives could deliver the same or similar benefits to those attributed to the project, then the applicant said the delegate had not properly compared the situation with and without the controlled action being taken.

This second argument drew heavily on the broader legislative framework established by the Water Act and the Basin Plan. The extract explains that this framework formed the context for the challenge, including the applicant’s submission that implementation of the Basin Plan required the return of significant volumes of environmental water to the Murray-Darling Basin. The applicant also argued that the offset strategy did not take into account legislative amendments made in December 2023 to increase the environmental water recovery target under the Water Act.

For business readers, this is where the case becomes especially practical. Many approval disputes are not about whether there is any environmental harm. They are about how impacts are characterised, what baseline is used, what assumptions are built into offset or mitigation strategies, and whether the decision-maker addressed the right statutory questions. Those are the kinds of issues that can later determine whether an approval survives challenge.

A useful feature of this case is that it helps explain a distinction that often confuses business owners and project teams: judicial review is not the same as merits review.

In merits review, the reviewing body effectively reconsiders the substance of the decision and may decide what the preferable outcome should be. In judicial review, the court does something narrower. It asks whether the decision-maker acted within power, addressed the legal task required by the statute, considered matters that had to be considered, and avoided reviewable legal error. The court does not simply step into the shoes of the Minister or delegate and remake the environmental balance for itself.

The extract makes that distinction important. The applicant challenged the approval by arguing that the delegate had mishandled the project’s impacts and benefits, especially in relation to offsets and the alleged counterfactual. But the Court’s role was not to decide whether the project should have been approved as a matter of environmental policy. Its role was to decide whether the approval decision was legally defective.

That distinction matters commercially. Businesses sometimes assume that if there is scientific uncertainty, public controversy, or a plausible alternative project design, a court may simply overturn the approval and substitute a better answer. That is not how judicial review works. A challenger usually needs to identify a specific legal problem, such as a failure to consider a mandatory matter, a misunderstanding of the statutory task, or a decision so unreasonable in the legal sense that it falls outside the range of lawful outcomes.

For proponents, this means the quality of the decision record is critical. For objectors, it means a challenge must be framed with precision. General dissatisfaction with the project, or even strong evidence that another option might have been preferable, will not necessarily establish legal error.

The Court dismissed the application. The extract states that neither of the applicant’s two main contentions was made out and that the applicant had not established any legal error affecting the approval decision. The formal orders show that the amended originating application dated 6 March 2025 was dismissed. The Court also set a timetable for written submissions on costs if the parties did not reach agreement.

On the material available, the Court did not accept that the alleged uncertainty in the offset strategy, the asserted failure to consider the alternative counterfactual, the arguments based on ecologically sustainable development and the precautionary principle, or the legal unreasonableness argument were enough to invalidate the approval. The approval therefore remained in place.

It is important to be careful about the level of detail that can safely be drawn from the published extract. The extract clearly records the issues argued and the result, but it does not reproduce every step of the Court’s reasoning. What can be said confidently is that the Court rejected the applicant’s challenge and upheld the approval decision against the grounds advanced.

For business readers, the practical message is that an approval can survive judicial review even where the project involves acknowledged environmental harm, provided the decision-maker has lawfully performed the statutory task. The existence of conditions, offset requirements, and a substantial assessment record can be highly significant in that analysis.

For project proponents, the case highlights the importance of building a defensible approval record from the start. The referral, the description of the project, the treatment of threatened species impacts, the offset strategy, the state assessment materials, and the final conditions all become part of the legal architecture that may later be tested in court. If your business is involved in infrastructure, water, land development, resources, energy, or environmental works, that record is not just a compliance formality. It is part of your litigation risk management.

The case also shows the value of consistency across documents. Here, the project moved through referral, controlled action, accredited assessment, variation, state inquiry, state ministerial assessment, and Commonwealth approval. In a long approval pathway like that, inconsistencies in assumptions, project scope, impact descriptions, or offset logic can create avoidable risk. Businesses should make sure later variations and updated reports still align with the statutory task the final decision-maker must perform.

For businesses affected by a project and considering a challenge, the case is a reminder that judicial review is targeted. It is not enough to point to uncertainty, controversy, or the possibility that another project or policy pathway might have delivered similar benefits. The challenge needs to identify a legal flaw in the actual decision. That may involve the decision-maker failing to consider a mandatory matter, asking the wrong legal question, misunderstanding the project’s impacts in a legally material way, or reaching a decision that is legally unreasonable.

For financiers, contractors, suppliers and landholders, the case is also commercially relevant because approval litigation can affect timing, cost and project certainty. Even if your business is not the approval holder, your contracts and delivery schedule may depend on the approval surviving challenge. That makes due diligence on the approval pathway and the quality of the supporting record commercially sensible.

Finally, the case is a reminder that broader policy frameworks may provide context without changing the legal source of power. The Water Act and Basin Plan were important background to the applicant’s arguments, but the approval under challenge was made under the EPBC Act. Businesses should always identify which statute actually governs the decision they are dealing with.

Businesses often ask whether a court challenge is a practical way to stop or delay a project. The answer depends on the kind of challenge available. This case shows that judicial review is a narrow tool. It can be powerful where there is a real legal defect in the approval process, but it is not a general appeal on the environmental merits.

Another common question is whether changing policy settings or later legislative amendments automatically undermine an approval. This case suggests caution. The applicant relied on changes to the broader Water Act and Basin Plan context, but the Court still dismissed the challenge. The existence of a changed policy environment does not by itself establish that the approval decision under another statute was unlawful.

Businesses also ask whether acknowledged environmental harm makes an approval vulnerable. Not necessarily. The extract records that the project would destroy critical Regent Parrot habitat, yet the approval remained valid because the challenge did not establish legal error. In regulated sectors, approvals often involve balancing impacts, benefits, conditions and offsets within the statutory framework.

The practical lesson is to match the legal strategy to the legal mechanism. If the issue is that the decision-maker broke the law, judicial review may be available. If the complaint is really that the project is a poor idea or that another option would be better, judicial review may not be the right vehicle.

The project was referred under the EPBC Act on 2 June 2020. It was declared a controlled action on 26 June 2020 and set for assessment through an accredited Victorian process on 20 July 2020. A variation of the proposed action was accepted on 18 November 2022. The Commonwealth approval decision challenged in this proceeding was made on 28 March 2024. The Federal Court heard the matter on 8 and 9 April 2025 and delivered judgment on 12 May 2026, dismissing the application.

At the time of judgment, the issue of costs had not been finally determined and was to be dealt with on the papers if not agreed between the parties. The public position that can be stated confidently is that the judicial review application was dismissed and the approval remained in place.

This page summarises Friends of Nyah Vinifera Park Inc v Minister for Environment and Water [2026] FCA 584 in the Federal Court of Australia. The published material identifies the proceeding as an application for judicial review of an EPBC Act approval decision concerning the Nyah Floodplain Restoration Project and records that the application was dismissed.

The published extract is detailed enough to explain the commercial story, the issues argued, and the result. However, readers should be cautious about relying on this page for fine-grained propositions about the Court’s reasoning on offsets, counterfactual analysis, ecologically sustainable development, the precautionary principle, or legal unreasonableness without checking the full reasons.
