ALERT: Some Planning System Reforms Commence
On 15 December 2025, amendments to the Environmental Planning & Assessment Act 1979 (EPA Act) by the Environmental Planning and Assessment Amendment (Planning System Reforms) Act 2025 (Planning System Reforms Act) commenced. Transitional and saving arrangements have also come into effect under the Environmental Planning and Assessment Amendment (Planning System Reforms) Regulation 2025.
The reforms to the EPA Act that have commenced include:
- Amending the objects of the EPA Act,
- Statutorily establishing the Housing Delivery Authority under Division 2.3A,
- Establishing the Development Coordination Authority under Division 2.3B,
- Establishing the power to constitute local planning panels for 2 or more specified areas under s 2.17,
- Amending the provisions relating to the appointment of members of local planning panels under s 2.18,
- Amending s 4.15 to restrict assessment to the ‘significant likely impact of the development’

- Introducing factors not of relevance to the consideration of a development application under s 4.15(1)(b) by s65A of the EPA Reg,
A large number of further amendments under the Planning System Reforms Act are to commence at a later date. These include:
- Inserting a new definition of ‘development standard‘ under s1.4(1),
- Establishing a single, state-wide Community Participation Plan for NSW under s 2.23,

- Amending s 4.17 to standardize conditions of consent,
- Expanding complying development, including introducing the issue of ‘variation certificates’ for CDCs under s 4.31A,
- Introducing targeted assessment development (TAD) provisions under Division 4.3A,
- Updating appeal options and review processes, and
- Abolishing Sydney district and regional planning panels.
Regionally Significant Development
A key feature of the Planning System Reforms Act is the removal of the regionally significant development pathways and staged abolition of Sydney district and regional planning panels.
The Environmental Planning and Assessment Amendment (Regionally Significant Development) Regulation 2025 published on 15 December 2025 amends section 275 of the EPA Reg to prescribe that the determination of a DA is a function of Sydney district or regional planning panel that must be exercised by the council of the area if a local planning panel has been constituted. The exception is that a council must not determine a DA on behalf of a Sydney district or regional planning panel if the application is of a kind specified in the ‘Instruction on functions not exercisable by council on behalf of Sydney district or regional planning panels – certain regionally significant development applications’ (Instructions). These include where:
- the application was lodged before 4 September 2024, or
- the council has submitted an assessment report in relation to the development to the applicable Sydney district or regional planning panel, or the application is taken to be refused and an appeal has been lodged, prior to:
- 16 January 2026, or
- the date that a Local Planning Panel is constituted for the land to which the application relates,
whichever is later.
The Regionally Significant Development Regulation is to commence on 16 January 2026. The Instructions were published on the NSW Planning Portal in December 2025.
