For energy developers, utilities, asset owners and environmental practitioners alike, Australia’s environmental reforms, in particular the draft Matters of National Environmental Significance (MNES) Standard, signal a step‑change in approvals practice.
The draft Standard sets clearer rules, stronger protections and a more transparent pathway for assessing impacts. Rather than treating environmental effects as a late‑stage hurdle, it expects avoidance and minimisation to be designed in from the outset that is backed by transparent evidence and authentic First Nations engagement. It also recognises temporary, repairable impacts more pragmatically, encouraging proponents to plan construction methods and sequencing early to reduce residual effects and future offset liabilities.
First, it’s important to acknowledge that the MNES Standard is about more than just regulatory housekeeping; it represents a transformational reform that will shape how projects are planned, assessed and delivered for many years to come. This transformation sees a major shift towards a “nature-positive” national framework, and one that is is impact-based, with implications spanning multiple sectors including renewable energy, infrastructure, mining, fossil fuels, property development, and agriculture.
While consultation on the reforms continues and final details may evolve, the implications for future project teams are already clear: lift the quality of concept‑stage decisions, document the mitigation hierarchy with greater rigour, and structure submission materials around the proposed evidentiary requirements.
In this article, Beca unpacks the key changes and share practice‑based insights to help you prepare for this change and to deliver future projects with confidence.
What is it?
The draft National Environmental Standards for MNES, released as part of the EPBC Act reform package, makes the mitigation hierarchy a clear and enforceable requirement for approvals under the Act. It also sets a consistent approach to assessing impacts to MNES, clarifies what impacts are considered unacceptable or repairable, and require evidence of First Nations engagement and consultation.
From concept to net gain
A focus of the reforms and the draft MNES Standard is for projects to leave a lasting, positive impact – a ‘net gain’ that reflects projects with benefits that endure across generations. By embedding the mitigation hierarchy as a test of approval, the reforms require proponents to demonstrate that every practical step has been taken to avoid, minimise, and rectify environmental impacts before considering offsets.
“There has always been an expectation to demonstrate in your assessment documentation that you’ve taken all steps to mitigate before offsetting,” Beca technical director – environmental science Warren McGrath said.
“However, invariably there has been inconsistency in terms of the rigour required of demonstrating consideration of options. The MNES Standard changes that. All future approvals under the Act will need to be consistent with the Standard, making it critical for proponents to clearly document each step, right from conceptualisation and siting.”
Plan early, offset less
The reforms encourage creative ingenuity, problem-solving and integrated thinking by looking beyond individual constraints to connect ideas, people and possibilities.
For proponents, the implications are clear: environmental constraints and opportunities must be considered from the outset and integrated into project planning and investment decision-making. The provisions for a streamlined “fast-track” assessment pathway provide a clear incentive to undertake this work early and document it through submission materials under the Act.
“Most corridor assessments projects I have been involved with are a great example of where constraints and opportunities are identified early across a broad area, and the corridor is refined progressively,” Beca principal environmental planner Melody Valentine said. “For other project types, considering environmental impacts right from the start will be a mindset shift.”
The Standard’s definition of “repairable impact” as minimal and temporary – such as those during construction, where the environment can feasibly be returned close to its original condition – offers a much-needed pragmatic approach to encourage application of the mitigation hierarchy.
“Previously, repairable impacts were encouraged to be addressed but weren’t given credit towards reducing offset liability,” McGrath said.
“Now, reparable impacts are recognised as part of the mitigation hierarchy, and if rectified they can represent temporary impacts that can be restored, reducing overall offset requirements. This is a significant shift from the previous approach to calculating residual impact, which will benefit developers looking for opportunities to reduce their offset liability.”
Future-ready approvals
Other practical elements of the reforms are future focused, streamlining approval pathways and supporting innovation so that today’s solutions remain relevant in tomorrow’s world. The new clause allows certain minor or preparatory activities, such as access tracks or investigation works (for example, geotechnical studies), to proceed before the assessment is completed, reflecting a more forward‑looking approach.
“One of the key practical benefits is the ability to undertake early preparatory works without waiting for full assessment, as long as they do not have potential to cause significant impact,” McGrath said. “For this, while the consent of the Minister at the time is to be sought, it offers practical benefits for developers, enabling faster project delivery and better planning.
“Previously, any activities associated with a broader action couldn’t proceed while an assessment was in progress, which could cause quite a headache for maintaining project schedules. This will make a real difference for project development managers.”
First Nations engagement – authentic and early
The requirement to demonstrate engagement with First Nations people during the assessment of a project is now enshrined in the MNES Standard, guaranteeing that consultation and knowledge-sharing are integral to every assessment.
“It’s now a principle of the standard to provide appropriate evidence of First Nations engagement and consultation,” McGrath said. “Assessment documentation must show how consultation has been undertaken and how First Nations knowledge has contributed to the process.
“Starting this conversation sooner in our community engagement on projects and in the right authentic way will be critical to ensuring their knowledge and voice are shaping our future projects.
“There are many great examples of this happening all over Australia already, but the key will be in how we capture the engagement outcomes early and demonstrate this with evidence for all our projects.”
Adapting workflows
Planners and proponents must adapt workflows to anticipate the coming MNES Standard changes. Early engagement with environmental and planning professionals is essential, as is careful consideration of transitional arrangements and timing.
“Projects nearing readiness for submission will need to decide whether to submit now or wait for new approval pathways and tests, especially if they could qualify for the fast-track pathway once in place,” Valentine said.
“There are unknowns, but anticipating rework and preparing upfront comprehensive documentation will be key.”
How can Beca help?
Beca is committed to helping clients evolve with these reforms.
“We provide a fully integrated service, engineering, design, planning, environmental, and geotechnical offering, working together to achieve optimum outcomes for the community, the environment, and our clients,” McGrath said.
“The changes under the new reforms and standards make this integrated approach more critical than ever.”
Where next?
The draft MNES Standard charts a clear path forward. For proponents and advisers, that means lifting the consistency of approach of early concept decisions and the traceability of assessment documents in reducing redesign, creating more predictable pathways, and delivering stronger environmental outcomes.
Beca is working with Australian clients to prepare for this change to Australia’s national regulatory landscape – a significant shift that will take time but, if implemented successfully, may not only streamline assessment processes but ultimately result in stronger, more consistent outcomes that will result in stronger protection of the natural environment.
As reforms are finalised, Beca will continue to share practical guidance and work collaboratively across the sector for its Australian client base.
