On 30 October 2025, the Australian Minister for Environment introduced three Bills to the federal Parliament that, if enacted, will constitute the most important change to national environmental law in 25 years.

The Environment Protection Reform Bill 2025 (Reform Bill), National Environmental Protection Agency Bill 2025 (NEPA Bill) and the Environment Information Australia Bill 2025 (Information Bill) propose substantial reforms to the operation of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) that would have significant implications for the environmental assessment and approval of projects in Australia.¹ The Bills were referred to the Senate Environment and Communications Legislation Committee for inquiry, with a reporting date of 24 March 2026, meaning that it is unlikely that any new legislation would be enacted before mid-2026.

The Bills are the Australian government’s response to an independent review of the EPBC Act conducted by Professor Graeme Samuel AC in 2020. The Samuel Review was highly critical of the complexity of the EPBC Act and its duplication with other Commonwealth and State and Territory environmental laws, and its failure to halt and reverse the decline in the Australian environment. It also made numerous recommendations to improve the Act, including the introduction and use of national standards, tying the accreditation of State and Territory assessment and approval processes to compliance with the standards, and simplifying the range of environmental impact assessment processes.

While the scope of reforms to the EPBC Act is broad, this article focusses on key reforms to the referral, environmental impact assessment and approvals process for controlled actions under Part 9 of the EPBC Act.

Key takeaways

The Minister for Environment would remain responsible for the environmental impact assessment and approval of projects.
A new National Environmental Protection Agency would be established as an independent regulator with enhanced compliance and enforcement powers.
The reforms propose bioregional plans to manage environmental impacts at a landscape or seascape scale, aiming to address cumulative impacts and streamline approvals for priority actions within designated development zones, while establishing conservation zones as 'no-go' areas.
Assessments on referral information, preliminary documentation and public environment reports would be replaced with a new streamlined assessment, in which there would be no public comment period, and the Minister could approve the action in 30 business days.
The Minister would be empowered to prepare National Environmental Standards to provide guidance on how to meet the requirements of the EPBC Act.
Approval of an action could not be inconsistent with a National Environmental Standard, must not have an unacceptable impact on matters protected by the EPBC Act and must not have a significant residual (ie., post avoidance and minimisation) impact on a protected matter unless it meets a new net gain test. However, these obligations on the Minister would not apply to actions that have been declared a national interest proposal or exempted on national interest grounds.

Governance and new agencies

The environmental impact assessment, approval and enforcement procedures and powers under the EPBC Act is the portfolio responsibility of the Commonwealth Minister for the Environment, supported by the Department of Climate Change, Energy, the Environment and Water (DCCEEW). In practice, the Minister has delegated many of its statutory powers and functions to senior DCCEEW officers.

The Bills propose to establish three new authorities:

National Environmental Protection Agency (NEPA) that would primarily have an enforcement role under the EPBC Act;
Head of Environmental Information Australia (HEIA), whose role would be to improve the availability, accessibility and quality of national environmental information and data for the Minister, the CEO of NEPA and the public. The HEIA would be required to prepare and publish a State of the Environment report and maintain environmental economic accounts, and make declarations about and publish national environmental information assets; and
Restoration Contributions Holder, whose role will be to pool and manage restoration contribution charges (discussed further below).

Importantly, the ultimate decision-making power for environmental assessments and approvals will remain vested with the Minister, although the Minister will be able to delegate its powers and functions to the CEO of NEPA or NEPA staff.

National environmental standards

A critical part of the Reform Bill is the power of the Minister to make National Environmental Standards. The Standards would provide guidance on how to meet the requirements of the EPBC Act. Any Standard made by the Minister must promote the objects of the EPBC Act, and not be inconsistent with Australia's obligations under international agreements and treaties.

Standards would specify outcomes or objectives, and may specify parameters, principles, processes or actions for achieving the outcomes or objectives.

Standards may be varied or revoked, but in so doing, the Minister must be satisfied that there is 'no regression' in protections of the environment as a result. Standards must be reviewed within 18 months of commencement, and at least every five years after that.

As elaborated below, the Minister's decision on whether to approve a controlled action must not be inconsistent with a National Environmental Standard,

Bioregional plans

Zoning

The Samuel Review was critical of the piecemeal nature of the environmental assessment and approval of individual projects, and the lack of attention to the cumulative impacts of development on the environment on a broader scale. In response to these concerns, the Reform Bill proposes a new Part 12A that would expand the scope for making bioregional plans within States and Territories that aim to manage the environment at a landscape and seascape scale as opposed to on a siloed project-by-project basis. This is intended to better address the cumulative impacts of development.

The Bill proposes that bioregional plans must include:

Development zones and the class of priority actions which can be taken within this zone. The Minister must be satisfied that the priority actions are likely to have a significant impact on protected matters, and these impacted protected matters must be specified in the bioregional plan;
Conservation zones and the class of restricted actions which are prohibited in this zone. The Minister must be satisfied that the restricted actions are likely to have a significant impact on protected matters, and these restricted protected matters must be specified; and
Bioregional restoration measures which the Minister is satisfied are necessary or convenient to mitigate, repair or compensate likely damage to the impacted protected matters caused by priority actions.

Development control

Proponents seeking to take a priority action in a development zone would be required to register the action with the Minister, but no referral or further approval under the EPBC Act would be required. This streamlined process is aimed to increase planning certainty, encourage investment, and promote efficient development within these zones. Bioregional plans may attach conditions to undertaking a priority action in a development zone.

Conversely, conservation zones would prohibit restricted actions, creating ‘no-go’ zones of environmental protection unless the proponent obtains an exemption.

The Minister would be able to vary, suspend or revoke bioregional plans.

Bioregional guidance

The Minister could also prepare bioregional guidance with the agreement of the relevant State or Territory. These would have no statutory effect, but contain information on the environmental and heritage values of the region to inform decision makers under the EPBC Act, and proponents.

Matters of national environmental significance

Changes to nuclear actions

The EPBC Act makes it a criminal offence to undertake a project or development (referred to in the Act as an action) that is having, or will or is likely to have, a significant impact on one of nine matters of national environmental significance, or MNES. One of the MNES is the impact of nuclear actions on the environment.

The Bill proposes to rename this MNES to radiological exposure actions and makes some adjustments to its definition, most notably to specify that the radiological exposure action of uranium mining and milling excludes operations for the recovery of mineral sands or rare earth elements. However, there remains to our mind some doubt of the benefit of this clarification for the relatively common situation where it is the processing and refinement of heavy metal concentrate and rare earth products, rather than the mining of ore and rehabilitation of mine sites, that trigger radioactivity levels.

No climate trigger

There has been much debate about whether the Reform Bill should include a 'climate trigger' MNES. The Reform Bill includes no such trigger, consistent with the recommendations of the Samuel Review.

However, with the Bill now referred to a Senate Committee and the possibility of the government having to secure Greens support in the Senate for the Bill to pass, the prospect of a climate change trigger being included in any new legislation cannot be ruled out for now.

Offsets and passing the net gain test

The Bill proposes changes to how offsets and compensation for environmental impacts will be managed, shifting away from a policy-based model towards a legislative regime that aims to promote greater certainty and transparency:

Legislating the Offsets Mitigation Hierarchy – Proponents would be required to demonstrate that they have taken appropriate measures to avoid, mitigate, or repair environmental impacts before any conditions related to compensation for residual significant impacts are attached to an approval. A residual significant impact is a significant impact that will not be avoided, mitigated or repaired in the course of taking the action or complying with conditions of an approval; and
The 'Net Gain Test' – Proponents are currently able to offset residual environmental impacts by achieving 'no net loss'. The Reform Bill proposes to raise the bar by introducing the net gain test, where every residual significant impact must be compensated so that the environment is, in theory, left better off than before that action. The net gain test can be passed if a condition is imposed on an approval that either requires the proponent to compensate for damage to a protected matter that constitutes a residual significant impact (eg, through offsets) or by paying a restoration contribution charge.

The Restoration Contributions Holder would collect and pool restoration contributions charges into the Restoration Contributions Special Account. The Holder would be tasked with strategically allocating funds towards specific restoration actions, ensuring that offset investments are targeted towards specific ecological conversation and regeneration projects.

Amendments are also proposed to the Nature Repair Act 2023 which would allow biodiversity certificates issued under that Act to be used for environmental offsetting purposes under the Act.

Impact assessment and approval of controlled actions

Referrals

The EPBC Act process is initiated by proponents of actions who refer their projects (or actions) to the Minister. This process is retained, but two notable amendments are proposed:

a proposed action cannot be referred if it is covered by an alternate pathway, discussed below; and
proponents would be able to apply for the Minister's written agreement to undertake an action that is a ‘minor or preparatory’ component of a larger action. This would remove the need for the fairly widespread current practice of proponents excluding preparatory works, such as geotechnical and environmental investigations, from the scope of a referred action so they can undertake the preparatory works without contravening the Act.

No controlled action – use it or lose it!

The Minister would continue to have the discretion to decide whether a referred action is not a controlled action that requires further assessment and approval under the EPBC Act. The key amendment proposed by the Reform Bill is that a no controlled action decision will lapse after 5 years if the action has not substantially commenced within that time. This lapse period will apply to any decision made after the commencement of the Reform Bill, regardless of whether the action was referred before, on or after that date.

This change is proposed to avoid 'land banking' of referrals, as well as situations where projects proceed based on dated or 'stale' impact assessment information.

Provision of greenhouse gas information

The Bill proposes that a proponent will have to provide a reasonable estimate of the likely amount of scope 1 or 2 greenhouse gas emissions, and the strategies and measures consistent with relevant laws and policies that the proponent will implement to manage those emissions. The information may be included in a referral, otherwise it must be included in an EIS, provided to an inquiry, or provided under the proposed new streamlined assessment process, described below.

The regulations could prescribe a threshold amount, below which a reasonable estimate and management strategies will not need to be disclosed.

The obligation to provide the greenhouse gas emission estimates would only apply to referrals made after the commencement date of the Reform Bill.

Streamlining the impact assessment processes for controlled actions

In addition to accredited State and Territory impact assessments discussed below, the Minister presently has five impact assessment procedures to choose from under the EPBC Act – assessment on referral information, assessment on preliminary documentation, public environment report, an environmental impact statement and public inquiry.

The Bill proposes to repeal three of these - assessments on referral information documentation, preliminary documentation and public environmental reports – and replace them with a new ‘streamlined assessment’ mechanism.

The streamlined procedure would essentially involve no public consultation, and an approval decision would need to be made within 30 business days of the Minister deciding that the action is to be assessed under the streamlined process. This is very rapid, and it is assumed that the project design and its impacts would need to be largely resolved and meet (or be quickly capable of meeting) the requirements of relevant National Environmental Standards for the Minister to decide the streamlined process should apply. The Explanatory Memorandum explains that the streamlined procedure is intended to incentivise developers to provide as much information as possible 'up front', presumably in the referral.

The streamlined assessment procedure is a significant innovation, and would allow very quick approval decisions to be made, provided the proponent can provide most, if not all, of the information about the controlled action and its impacts to enable to the Minister to make an informed decision on whether to approve it – although the Minister would still be able to 'stop the clock' by requesting information about the controlled action and its effects before making a decision.

The proposed changes to the impact assessment processes will not affect assessments already underway when the Reform Bill commences.

Ministerial approval decisions

Perhaps one of the strongest criticisms made by the Samuel Review was the absence of an objective or purpose that should be met when deciding whether to approve a controlled action. This has left many to criticise the EPBC Act as regulating the destruction of the Australian environment rather than protecting it. The Reform Bill seeks to overcome this criticism by requiring a decision to approve a controlled action:

be 'not inconsistent' with an approved National Environmental Standard;
not have an unacceptable impact. The Bill includes a tabulated definition of unacceptable impact by reference to each of the protected matters. For example, an unacceptable impact in respect of listed species is an impact that seriously impairs (that is, alters for the worse), will seriously impair or is likely to seriously impair the viability of a species;
not have a residual significant impact on a protected matter unless it passes the net gain test, discussed above;
be 'not inconsistent' with Australia’s obligations under the Ramsar Convention and Australia's Ramsar management principles and management plans for wetlands of international significance;
be not inconsistent with Australia’s obligations under the Biodiversity and APIA Conventions and CITES; and
be not inconsistent with a threat abatement plan, protection statement or recovery plan prepared under the EPBC Act.

These obligations will only apply to referrals of actions made after the commencement of the Reform Bill.

Moreover, these constraints would not apply to approving the controlled action if it was a national interest proposal. The inclusion of a national interest carve-out has come in for much comment, and is considered in further detail below.

Similar considerations also apply to decisions to revoke, vary or add to any conditions of an approval, including in respect of approvals granted before the commencement of the Reform Bill.

Alternate approval pathways

As an alternative to the conventional referral, assessment and approval of controlled actions under the process summarised above, the Bill proposes that certain actions or classes of actions (excluding certain radiological exposure actions) can be declared under the following alternate pathways that are accredited by the Minister:

a declared management or authorisation framework established under Commonwealth law;
a framework administered by the NOPSEMA in respect of offshore petroleum and carbon capture storage activities in the Commonwealth marine area;
a declared management or authorisation framework established under State or Territory law accredited in a bilateral agreement between the Commonwealth and the State or Territory;
an approved plan, policy or program under the strategic assessment and approval provisions in Part 10 of the EPBC Act; and
certain permissible actions under a bioregional plan, discussed above.

A declared action or class of action would be permitted to have a significant impact on a protected matter without approval.

Exclusions based on the national interest

National interest exemption

The EPBC Act has long included an ability for the Minister to grant an exemption on national interest grounds from the application of Chapter 4 (which establishes the requirements for assessment and approvals in the EPBC Act). The national interest is not precisely defined, so that the Minister may have regard to Australia’s defence or security or a national emergency, but can also consider other matters in determining the national interest.

The Reform Bill inserts a new national security exemption, which explicitly enables the Minister to impose conditions on actions covered by the exemption and provide for a set period for which the exemption applies.

National interest proposal

The concept of national interest proposals is a new and controversial aspect of the Reform Bill.

It is proposed that if a project is a controlled action that requires assessment and approval, the Minister can determine the controlled action to be a national interest proposal. This would empower the Minister to approve the national interest proposal even if it is inconsistent with National Environmental Standards or will or is likely to have unacceptable impacts. Furthermore, national interest proposals which have a residual significant impact need not pass the net gain test.

The Minister would possess a broad discretion in deciding what is a national interest proposal, expanding the test applied to national interest exemptions to 'Australia's defence, security or strategic interests’ and 'existing international obligations', while also retaining the scope to consider other matters in determining the national interest.

Other issues

The Reform Bill proposes other important reforms including:

procedures for proponents to surrender approvals;
substantial changes to limit the scope for third parties to request the Minister to reconsider controlled action decisions, as well as other amendments to the Minister's reconsideration powers to limit their potential to disrupt the development of actions that had been found not to be a controlled action;
the power of the Minister to make rulings about how the EPBC Act, regulations and subordinate instruments (such as the National Environmental Standards) should be applied. These rulings would bind the Minister, the CEO of NEPA and delegated decision-makers;
changes to the strategic assessment of plans, policies and programs and the approval of actions and classes of actions under Part 10 of the EPBC Act. These changes introduce greater flexibility to the strategic assessment process and address the new reforms concerning National Environmental Standards, unacceptable impacts and significant residual impacts;
significantly increased criminal and civil penalties, as well as empowering the courts to impose a civil penalty by using a formula that considers either or both the benefit derived from the breach of the EPBC Act (i.e., total value of all benefits obtained that are reasonably attributable to the contravention) and the detriment avoided (i.e., by the contravention, or by reference to the defendant’s annual turnover). It is designed to ensure penalties are proportionate to the scale of wrongdoing or financial position of the offender;
empowering the CEO of NEPA to issue environment protection orders to remedy non-compliance with the EPBC Act, regulations or conditions of an approval or exemption if it is causing, or poses an imminent risk of, serious damage to a relevant protected matter; and
extensive transitional provisions.
