How the Minns Government’s overhaul of a 50-year-old planning system could reshape development across Sydney.
NSW is on the cusp of the biggest shake-up to the planning system in more than five decades. The Minns Government has introduced the NSW Planning System Reforms Bill 2025, aimed at accelerating housing delivery, reducing bottlenecks, and bringing long-overdue structure to an increasingly complex planning landscape.
For developers, landowners, and anyone navigating DAs in Sydney, these changes could materially influence project feasibility, timing, and strategy.
Below is a clear breakdown of what’s changing and what it actually means for you.
A New Development Coordination Authority
A whole-of-government coordinating body will now sit above agencies to streamline advice and approvals.
What this means:
Developers should see fewer contradictory agency requirements and faster resolution of inter-departmental issues, especially for complex rezonings and major developments.
Housing Delivery Agency Embedded Into Law
The HDA will now play an ongoing, legislated role in housing strategy and statewide housing delivery.
What this means:
Expect a more hands-on government approach to housing targets, with greater oversight on where and how housing must be delivered.
Complying Development Expanded – With Automatic Approval After 10 Days
If no decision is made within 10 days, a “deemed approval” will automatically apply.
What this means:
This is one of the biggest shifts. For compliant, lower-risk projects, delays driven by administration should dramatically reduce.
New Targeted Assessment Pathway
A middle-tier assessment route for projects that meet strategic planning priorities.
What this means:
Projects aligned with strategic documents (Housing SEPP, Local Housing Strategies, Transport corridors, etc.) can expect a more predictable pathway, instead of falling back into full DA complexity.
Scaled DA Requirements
Assessment will now match the actual complexity of the project — not a blanket one-size-fits-all approach.
What this means:
Simpler/smaller developments should face shorter timeframes and fewer consultant requirements.
Standardised Consent Conditions
The state’s biggest pain point — inconsistent conditions — is being addressed.
What this means:
Developers should see fewer ad hoc or overly burdensome conditions and more consistency across councils.
Statewide Community Consultation Framework
Community engagement will finally be standardised.
What this means:
More predictability around consultation periods and fewer “surprise” localised requirements.
Updated Objectives of the Act
Housing supply, climate resilience and proportional assessment are now core statutory objectives.
What this means:
Councils will need to show how their decisions align with these objectives — an important shift in balancing risk-avoidance with enabling development
Removal of Regionally Significant Development Pathway
Large projects will now be funnelled through updated local/state pathways.
What this means:
Potentially fewer duplicated processes and faster escalation when needed.
Appeal and Review Processes Updated
The system will favour faster, out-of-court resolution options.
What this means:
Less litigation, faster certainty — particularly valuable for project timelines and finance terms.
So… Will These Reforms Actually Speed Up Development?
Potentially — yes.
The structure is strong, the intent is clear, and the emphasis on certainty, standardisation and faster decision-making is positive.
The real test will be in execution.
Councils, assessment panels, and state agencies must all apply the new rules consistently — and with the resources to support them.
What Developers Should Do Next
To make the most of the reforms as they roll out:
- Map your existing/active DAs and identify where the scaled assessment rules could reduce time or complexity.
- Review upcoming projects to determine whether Complying Development becomes viable.
- Reassess feasibility assumptions — faster approvals may change holding costs and staging.
- Stay across transition provisions — some clauses include savings provisions that may affect projects already lodged.
- Engage early — pre-lodgement advice and strategic alignment will matter more than ever.
If you hold development sites in Western Sydney, these changes may improve the speed and viability of your next project — but they will not impact all sites equally.
