Environmental Planning and Assessment Act 1979

Executive summary of update

Effective date: 21 March 2026

This update introduces significant reforms aimed at streamlining planning processes and formalizing new administrative bodies. The most critical changes include the establishment and operationalization of the Housing Delivery Authority and Development Coordination Authority, the creation of a new “targeted assessment development” category with limited assessment criteria, and a “deemed approval” mechanism for minor development consent modifications. Additionally, environmental impact assessment for certain activities is now explicitly proportionate and risk-based, and past affordable housing conditions have been retrospectively validated. The primary intent is to accelerate development approvals and enhance administrative efficiency, with the most significant practical consequence being faster processing times for specific development types and clearer roles for new planning authorities.

Impacted parties

This update significantly impacts development applicants, consent authorities (including councils, panels, and the Minister), the newly established Housing Delivery Authority and Development Coordination Authority, and project managers involved in environmental impact assessments.

Change Analysis

1. Introduction of Targeted Assessment Development and Streamlined Assessment

What changed:

• A new definition for targeted assessment development has been added in Section 1.4.
• A new Division 4.3A (Sections 4.20A-4.20B) has been inserted, allowing State Environmental Planning Policies (SEPPs) to declare development as “targeted assessment development” with specific criteria. This division prevails over other inconsistent Part 4 provisions.
• Section 4.15(1C) and (1D) now mandate that for targeted assessment development, consent authorities must only consider provisions of environmental planning instruments/regulations and submissions, explicitly excluding broader environmental, social, economic impacts, site suitability, and public interest.
• Section 4.43(2) clarifies that State Significant Development (SSD) provisions do not override targeted assessment development provisions.
• Schedule 1, Clause 9C introduces specific, potentially shorter, public exhibition periods for targeted assessment development, allowing SEPPs to define or waive these periods.

Why it matters: This creates a new, highly streamlined assessment pathway for certain types of development. While it aims to accelerate approvals by narrowing the scope of matters for consideration, it also means that broader environmental, social, and economic impacts will not be assessed for these developments, potentially leading to less holistic planning outcomes. Developers of targeted assessment development will benefit from faster processing, but community groups may have reduced avenues for input on broader impacts.

2. Formalization and Operationalization of New Planning Authorities

What changed:

• The definitions of Housing Delivery Authority (HDA) and Development Coordination Authority (DCA) are now active in Section 1.4.
• New Divisions 2.3A (Sections 2.11A-2.11D) and 2.3B (Sections 2.11E-2.11I) fully establish these bodies, outlining their constitution, membership, functions, and operational provisions.
• The HDA’s functions include advising the Minister on housing supply, SSD declarations, and zoning, with transparency requirements for the Minister’s decisions.
• The DCA is identified as the Planning Secretary, with functions including providing advice and coordinating development.
• Section 2.11H mandates information sharing from public authorities to the DCA.
• Section 2.4(1) now explicitly allows the Minister, Planning Ministerial Corporation, or Planning Secretary to delegate functions to the HDA and DCA.
• Section 2.28 extends personal liability exclusion to members of the HDA.
• Sections 7.44, 7.45, and 7.46 now include the HDA and DCA as entities that can demand, levy, recover, and receive charges and fees.
• Schedule 2, Clause 1 includes the HDA in the definition of a “planning body,” subjecting it to general procedural provisions.

Why it matters: This formalizes key new players in the planning system, centralizing housing delivery and development coordination efforts. The HDA’s advisory role and the DCA’s information-sharing powers are intended to improve efficiency and strategic alignment across government. For external parties, this means new points of contact and influence in the planning process, particularly for housing-related projects. The ability to levy fees and recover costs also impacts project budgeting.

3. Streamlined Minor Modifications with Deemed Approval

What changed:

• Section 4.55(1) has been amended to include modifications with “no environmental impact” under the same streamlined process as minor errors, misdescriptions, or miscalculations. These modifications are now explicitly exempt from public notification, advertising, and submission consideration requirements by virtue of Section 4.55(1AA).
• A new Section 4.55A introduces a “deemed approval” mechanism for applications made under Section 4.55(1). If a consent authority fails to determine such an application within a prescribed period, it must determine it as soon as practicable thereafter and must not refuse it, subject to certain conditions.

Why it matters: This significantly reduces the regulatory burden and processing time for minor changes to development consents. For project managers and developers, this means faster adjustments to approved plans, reducing delays and costs. However, it also means less public scrutiny for modifications deemed to have “no environmental impact,” which could be a concern for community stakeholders. Internal compliance teams must ensure strict adherence to prescribed periods to avoid deemed approvals.

4. Proportionate Environmental Impact Assessment

What changed:

• Section 5.5(1), which outlines the duty of determining authorities to consider environmental impact, has removed the phrase “to the fullest extent possible.”
• A new Section 5.5(2) has been inserted, explicitly stating that a determining authority may take into account environmental matters “in a manner that is proportionate to the nature and risk of the activity.”

Why it matters: This represents a significant shift towards a more flexible, risk-based approach to environmental impact assessment for activities under Division 5.1. It allows authorities to tailor the depth of assessment to the perceived risk, potentially speeding up approvals for lower-impact activities. However, it also introduces discretion that could lead to less rigorous environmental scrutiny if not applied carefully.

5. Retrospective Validation of Affordable Housing Conditions

What changed:

• A new Part 7, Clause 14 has been added to Schedule 4 (Savings, transitional and other provisions).
• This clause retrospectively deems Environmental Planning and Assessment Amendment Act 2025, Schedule 1[37] and [38] to have commenced on 1 March 2018.
• It explicitly validates any conditions imposed under Section 7.32 (Conditions requiring land or contributions for affordable housing) on or after 1 March 2018 that would otherwise have been invalid due to the later commencement of those amendments.

Why it matters: This is a critical retrospective legal validation. It provides certainty and legal enforceability for affordable housing conditions that may have been imposed on development consents over the past several years, which could have been vulnerable to challenge. This impacts developers who may have contested or are currently contesting such conditions, and provides a clear legal basis for councils and the HDA to continue enforcing and imposing these contributions.

Risks & opportunities assessment

The update presents a strategic shift towards greater efficiency and targeted intervention in the planning system. The formalization of the HDA and DCA offers an opportunity for more coordinated and strategic housing and infrastructure delivery, potentially unlocking development bottlenecks. The “targeted assessment development” and streamlined minor modification processes could significantly reduce project timelines and costs, enhancing productivity and investment attractiveness. However, these efficiencies come with risks: the reduced scope of assessment for “targeted assessment development” and the “proportionate” approach to environmental impact could lead to less comprehensive scrutiny of projects, potentially increasing long-term environmental or social liabilities if not managed carefully. The retrospective validation of affordable housing conditions provides certainty but may also reignite past disputes or impact financial models for projects already underway. Overall, the changes create opportunities for faster, more predictable approvals for certain developments, but demand heightened vigilance in compliance and stakeholder engagement to mitigate risks associated with reduced oversight.
