Why the NSW Planning System Feels Like a Maze

In New South Wales, the planning system is a critical mechanism for shaping land use, development, housing supply and infrastructure. But for many stakeholders — developers, councils, community groups and individual landowners — what should be a pathway to progress often feels like a labyrinth.

Learn why the system is so complex, what impacts this complexity has, and how recent reforms are attempting (or pledging) to simplify things — insights which could be crucial to the success of your project.

Why is the NSW Planning system so complex?

There are several interlocking reasons:

a) Multiple layers of legislation and policy

The system is built around the Environmental Planning and Assessment Act 1979 (EP&A Act), but also supplemented by Regulations, State Environmental Planning Policies (SEPPs), Local Environmental Plans (LEPs), Council Development Control Plans, ministerial directions, circulars and more. 

b) Broad functions and approvals pathways

The system manages both strategic land-use planning (zoning, precincts, local and regional strategies) and development control (assessment of applications, certifications). For development applications alone, there are numerous approval pathways under the EP&A Act. Each pathway triggers different standards, assessment levels, authorities and public participation obligations.

c) Multiple stakeholders and assessment authorities

Local councils, state government agencies, certifiers, infrastructure providers, environmental authorities, sometimes federal involvement (for matters of national environmental significance) — all form part of the chain.
This means overlapping jurisdiction, potential duplication and coordination issues.

d) Legacy, incremental change & complexity creep

The EP&A Act dates from 1979; over decades many amendments, layering of new instruments, case law and policy add-ons have compounded complexity. Analysts note the system “has become a barrier preventing the delivery of much needed homes… the level of assessment required for simple developments is disproportionate to their impact on communities.” 

e) Broad and subjective criteria

Some of the requirements for assessment are broad, sometimes vague, resulting in uncertainty. For example, the list of “considerations” under section section 4.15 of the EP&A Act has been criticised for being “too broad” and making the system slow, unpredictable and open to interpretation.

What are the practical impacts of this complexity?

The complexity has real consequences:

• Delays in approvals: Slow decision-making means slower delivery of housing, infrastructure and development. The McKell Institute points out that Sydney has been slower in approving new development compared to other capital cities, in part because of the complexity of the NSW planning system. 

• Higher costs & risk: Developers face greater cost exposure, longer holding costs, and more uncertainty about outcomes; small-scale landowners or renovators may also feel overwhelmed.

• Uncertainty for communities & stakeholders: When rules are opaque or subjective, stakeholders may struggle to know what is required or how a decision will land.

• Housing supply constraints: The system’s complexity is one of the factors blamed for constrained housing supply and affordability pressure in NSW. 

• Need for coordination: With so many actors, approvals can get caught up in multiple reviews, referrals, concurrences and varying expectations.

What’s being done (or promised) to simplify things?

Recognising the problem, the NSW Government has recently introduced reform initiatives aimed at streamlining the system:

• The Planning System Reforms Bill 2025 (an amendment to the EP&A Act) aims to modernise and simplify the system. 

• Key changes:

  • Introduce objects in the Act that emphasise housing supply, productivity, risk-based assessment and climate resilience. 

  • Establish a new “single front door” agency (the Development Coordination Authority) for coordinating major development applications involving multiple government agencies. 

  • Expand the ‘complying development’ stream and introduce a ‘Targeted Assessment Pathway’ for developments that have had prior community or strategic review — to reduce duplication. 

  • Introduce a risk-based approach so that assessments are proportionate to complexity/impact. 

Why simplification is hard (and what to watch out for)

While reform is welcome, simplification isn’t straightforward:

• Implementation matters: Even with reform, how new pathways are interpreted, how agencies coordinate, how the ‘single door’ works will determine whether the system actually becomes easier.

• Balancing scrutiny and speed: Simplification must not erode good planning outcomes (environmental protection, community participation, infrastructure sequencing) in the name of speed.

• Legacy applications and entrenched behaviour: Many existing approvals, processes and stakeholder behaviours are built around the older system; change takes time.

• Risk of unintended consequences: As critics note, simplifying assessment might shift risk, reduce oversight or make outcomes less predictable. (For example, recent commentary warns that broad new pathways could reduce environmental or community safeguards.)

What this means for professionals & stakeholders:

For planners, developers, consultants, community-representatives, local government, state agencies and others with a stake in the NSW planning system:

• Stay informed: Understand the old rules and how the new reform pathways might apply in your context.

• Engage early: Given the multiple layers and agencies, early coordination (with councils, state agencies, infrastructure providers) is critical.

• Proportionate approach: For smaller or lower-impact developments, look for opportunities to use simplified assessment pathways, such as exempt or complying development options.

• Expect change: Be ready for practical changes in workflow, documentation, approvals culture as reforms roll out.

• Advocate clarity: Transparent criteria, clear pathways and predictable timelines are vital for reducing risk; call for them in your projects and don’t cut corners in preparing your application.

Pursuing the balance between oversight and overkill

The NSW planning system is undeniably complex — but that complexity is also rooted in genuine ambition: balancing land-use, environment, infrastructure, community, housing, economic and social goals to protect the liveability of our places. The challenge is to make the system workably simple, without diluting its purpose or rigour. The reforms under way attempt to make that happen. For those of us working in or alongside that system, the time is ripe to adapt, to engage and to help shape a planning framework that is fit for the challenges of the future.

What does this mean for your project?

Attempting to navigate the NSW Planning system yourself could result in higher costs and length project delays. At Blue Sky Planning & Environment, our experience in regional & rural town planning from the perspectives of both the applicant and the approval authority means we use a tried and tested approach to approval pathways. Working with us means minimising the chances of time and cost blowout whilst delivering a project that considers all the intersecting factors that may apply to your unique situation.
