EPBC Act Reforms and NEPA 2026: What Developers Need to Know

EPBC Act Reforms 2026: What Changed on 1 July

On 1 July 2026, the National Environmental Protection Agency (NEPA) commenced operations, taking over the compliance, enforcement and assessment functions previously handled within the Department of Climate Change, Energy, the Environment and Water. The reforms were delivered through three Acts passed in late 2025: the Environment Protection Reform Act 2025, the National Environmental Protection Agency Act 2025 and the Environment Information Australia Act 2025.

This is the most significant change to Australia’s national environmental laws since the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) itself. The reforms do not introduce federal environmental oversight for the first time. The EPBC Act has required referral and assessment of projects likely to significantly affect a matter of national environmental significance since it commenced in 2000. What changed in 2026 is who regulates and how enforcement works: those functions now sit with a dedicated regulator that has stronger audit powers and substantially higher penalties available under the reformed framework.

For property developers, planners and project managers operating across Queensland, New South Wales, Victoria and South Australia, understanding the practical implications of these changes has become a core part of project risk management.

What Is NEPA and What Does It Do?

NEPA is Australia’s first dedicated federal environmental regulator: an independent statutory agency with its own compliance and enforcement powers. That independence has limits worth understanding. The Minister for the Environment retains significant roles under the reformed framework, including approvals in the national interest and bilateral agreements with the states, and NEPA exercises a number of its assessment and approval functions under Ministerial delegation. In practical terms, proponents now deal with a regulator that has the mandate and the legal tools to pursue non-compliance in its own right.

NEPA’s core functions include:

• Issuing permits and licences under Commonwealth environmental law, including the EPBC Act
• Conducting compliance audits of projects subject to EPBC approvals or conditions, including unannounced audits
• Enforcement action, including compliance notices, civil penalty proceedings and criminal prosecutions
• Maintaining a public register of registerable decisions and compliance outcomes
• Monitoring conditions attached to existing EPBC approvals

Financial exposure for serious contraventions has increased substantially. Under the reformed penalty provisions, civil penalties for corporations can reach the greatest of $16.5 million, three times the benefit gained from the contravention, or 10 per cent of annual turnover, capped at $825 million. Individuals face civil penalties and, for serious offences, criminal liability. The era of treating EPBC conditions as largely administrative obligations is over.

EPBC Referral Triggers: When Does Your Project Need Federal Assessment?

The referral triggers themselves have not changed, but how they are assessed, enforced and monitored has. Your project requires referral under the EPBC Act when it is likely to have a significant impact on any of the following matters of national environmental significance (MNES):

• Threatened species and ecological communities listed under the EPBC Act
• Migratory species protected under international agreements
• Ramsar wetlands of international importance
• World Heritage properties
• National Heritage places
• Commonwealth marine areas
• The Great Barrier Reef Marine Park
• The environment of Commonwealth land
• Nuclear actions
• Water resources, in relation to coal seam gas and large coal mining developments (the water trigger)

A project does not need to be located within a protected area to trigger referral. Impacts can extend well beyond the project boundary: hydrology changes, noise, dust, light and habitat fragmentation can all constitute a significant impact on listed species kilometres away. Greenfield developments, infrastructure corridors, quarries and coastal projects are consistently the highest-risk project types for EPBC triggers in Australian practice.

A further change arrives on 1 December 2026. Two familiar assessment routes, assessment on referral documentation and the public environment report, are being retired in favour of a single streamlined assessment pathway (the legislative name for the new route) with decisions required within 30 business days. The pathway is not available for fossil fuel actions and does not include a public comment period, which places the full weight of your case on the quality of the referral documentation you lodge. Poorly prepared referrals risk rejection or requests for further information that can add months to a program.

What Changes for Contaminated Land?

The contaminated land implications of NEPA are often overlooked but matter a great deal for certain sites. Where a contaminated site has existing EPBC approval conditions attached (common on former industrial sites, defence land, landfills near sensitive receptors and coastal remediation projects), those conditions are now actively monitored by NEPA rather than passively managed within a department.

NEPA’s unannounced audit powers mean that site owners and their environmental consultants must ensure:

• All environmental management plans referenced in EPBC conditions are current, implemented and documented
• Monitoring data (groundwater, soil vapour, surface water) is being collected at the required frequencies and reported correctly
• Any material changes to site conditions or remediation progress are disclosed promptly
• Ecological offset conditions are being actively met, not merely committed to on paper

For sites where contamination could affect listed species habitat (for example, PFAS migration into wetland or estuarine environments, or hydrocarbon contamination near waterways with listed fish species), state EPA obligations and federal NEPA oversight must both be satisfied at the same time. That calls for coordinated environmental management that considers both regulatory frameworks from the outset of any investigation or remediation program.

Practical Steps for Developers and Project Proponents

The reforms reward proponents who front-load their environmental due diligence. For any Australian project with a potential environmental footprint, we recommend the following:

1. Commission a desktop EPBC referral assessment early, ideally at feasibility stage and before significant capital is committed. A qualified CEnvP can assess whether your project has the potential to trigger MNES impacts and prepare a referral strategy.
2. Review all existing EPBC approval conditions for acquired or transferred sites. NEPA has inherited oversight of all pre-existing approvals and can audit compliance at any time.
3. Integrate ecological and contamination assessment programs on complex sites. Where both EPBC triggers and contaminated land obligations exist, a coordinated investigation and management approach is far more efficient and reduces regulatory risk.
4. Update your environmental management plans, including any construction environmental management plan (CEMP), to reflect current conditions and the new regulatory context. Plans prepared before 2026 may reference superseded referral pathways or agency contacts that no longer apply.
5. Brief your legal team on the increased penalty provisions. The reformed civil penalty framework is substantially tougher than the previous regime and extends to directors and officers in certain circumstances.

What About State-Level Obligations?

State and territory environmental laws remain in full force. NEPA operates in parallel with, not in replacement of, state EPAs. In practice, this means:

• Queensland: Projects subject to Environmental Protection Act 1994 obligations (including environmental authorities and site management plans) must also comply with any applicable EPBC and NEPA requirements.
• New South Wales: Contaminated land investigations under the Contaminated Land Management Act 1997 and State Environmental Planning Policy (Resilience and Hazards) 2021 proceed alongside any federal referral process. The NSW EPA duty to report contamination provisions remain unchanged.
• Victoria: The Environment Protection Act 2017 General Environmental Duty continues to apply, and planning referrals under the Planning Policy Framework remain operative.
• South Australia: The Environment Protection Act 1993 and site contamination provisions in the planning system are unaffected by NEPA’s establishment.

Effective project management now requires environmental consultants, planners and legal advisers to work across both state and federal regulatory frameworks from early project conception.

Common Questions

My project already has EPBC approval. Do I need to do anything under NEPA?

Yes. NEPA has inherited oversight of all existing EPBC approvals and can conduct compliance audits without notice. Review your approval conditions now, confirm all obligations are being met, and make sure your environmental management documentation is current. Any material changes to your project or site conditions should be disclosed to NEPA promptly.

How do I know if my site contains listed species that could trigger an EPBC referral?

A desktop threatened species assessment using the EPBC Act Protected Matters Search Tool (PMST), combined with a review of state biodiversity datasets, is the standard starting point. Where the desktop review identifies potential listed species, a targeted field survey by a suitably qualified ecologist is required to characterise the actual risk. Seasonal survey windows are critical: some species can only be reliably detected at specific times of year, and surveys conducted outside the appropriate window may not be accepted by the regulator.

What does an EPBC referral assessment cost?

Desktop referral assessments for straightforward projects typically range from $3,000 to $8,000 depending on complexity and the number of potential MNES triggers. Where field surveys are required, costs increase substantially: targeted species surveys can range from $5,000 to $30,000 or more depending on the species, survey method, season and site access. A formal EPBC referral, if required, typically costs $15,000 to $50,000 and above for complex or large-scale projects. Set against the penalties available under the reformed framework, early assessment is inexpensive insurance.
