A single state agency referral on a development application in NSW has historically added an average of 60 days to assessment time. Each additional referral on top of that has added up to 100 days more. For developers carrying finance costs, managing contractor programs, and working to pre-sales deadlines, those delays are not inconveniences — they are real financial exposure.
That problem is what the Development Coordination Authority NSW has been designed to fix. The Development Coordination Authority (DCA) was formally established in December 2025 and will take on full statutory powers from 1 July 2026. It is the most significant structural change to the NSW planning referral system in years, and most developers, project managers, and civil engineers have not yet factored it into their programs.
This article explains what the DCA is, what it replaces, how it changes the referral process from the second half of 2026, and what project teams should be doing right now to prepare.
What Is the Development Coordination Authority?
The DCA is a body housed within the NSW Department of Planning, Housing and Infrastructure. Its function is to act as a single coordination point for state agency input on development applications and planning proposals across NSW.
Before the DCA, applicants and Councils dealing with a DA that required State agency input had to manage relationships with up to 22 separate areas of Government. Each agency operated on its own process, its own internal timeline, and its own interpretation of what was required. There was no obligation for those agencies to align their positions, no single clock running, and no mechanism to resolve conflicting advice before it landed back on the applicant’s desk.
The DCA changes that structure entirely. From July 2026, it brings together experts from up to 14 NSW Government agencies under one coordination point. The Planning Secretary takes on the DCA’s functions, issuing concurrences and general terms of approval on behalf of state agencies rather than each agency responding independently.
The key point to understand: the DCA is not the Consent Authority. It does not determine or approve your Development Application. That function stays with your Council or, for State Significant Development, with the Planning Secretary in a separate capacity. The DCA’s role is to coordinate and consolidate the state input that feeds into that determination.
The Scale of the Problem It Is Solving
The existing referral framework has never been purpose-built as a system. It evolved over decades as different agencies attached their own triggers, timeframes, and processes to over 175 separate planning instruments. The result is more than 800 individual referral triggers scattered across those instruments, each requiring its own submission, its own assessment, and its own response.
For a project that crosses multiple trigger thresholds (a subdivision near a state road, a waterway, and a bushfire prone area, for example), each of those referrals was historically a separate process running on a separate clock. The DCA replaces that fragmentation with a single process and a single mandatory response window.
What Did the Old NSW Development Referral System Look Like?
Understanding what the DCA replaces is important context for grasping the scale of what is changing.
Under the existing framework, a Development Application that triggered State Agency input required the applicant or Council to refer the matter to each relevant agency separately. These agencies included Water NSW, Transport for NSW, the Rural Fire Service, Heritage NSW, and others depending on the nature and location of the project. Each had its own assessment process and, in practice, its own response culture.
The existing legislated timeframes were inconsistent. Most concurrences and integrated development referrals had a 21-day clock from receipt of submissions. Some instruments specified 40 days. Heritage referrals under certain Local Environmental Plans ran to 28 days. In practice, those timeframes were not always met, and there was no single mechanism to enforce them or resolve situations where agencies returned conflicting positions.
The Commercial Reality of Referral Delays
The numbers from the NSW Government’s own analysis are direct. A DA requiring a single state referral took an average of 60 days longer than a comparable application without one. Add a second referral and the cumulative impact could push to 100 additional days or more.
For a developer carrying construction finance at current rates, 60 to 100 additional days in assessment is not a line item, it is a meaningful increase in project cost and risk. For a Project Manager trying to hold a civil contractor program together, an unresolved agency referral is one of the most common causes of programme slippage during the pre-construction phase.
The reform response acknowledges this directly. The NSW Government’s announcement framed the DCA as removing the need for applicants and Councils to deal with multiple departments independently, with conflicts resolved inside the DCA before a response goes out.
How the Development Coordination Authority Changes the Referral Process from July 2026
The DCA operates in two stages. Understanding the distinction matters for any project currently in assessment or about to be lodged.
Stage 1: What Is Already Live (December 2025)
Stage 1 commenced in December 2025. In this phase, the DCA is operating in an advisory capacity. It provides guidance and recommendations to the Minister for Planning, resolves enquiries related to integrated development, concurrences, referrals, and housing-related post-consent issues.
If you have a DA currently in assessment that involves state agency referrals, Stage 1 DCA is already available to help resolve enquiry-level issues. This is not yet the full reform, it is the foundation being put in place before the statutory machinery starts in July.
Stage 2: Full Statutory Powers from 1 July 2026
From 1 July 2026, the DCA takes on the powers that make this reform substantive. Under Stage 2, the DCA:
- Issues concurrences and General Terms of Approval on behalf of State agencies, replacing the need for direct referrals to agencies such as Water NSW, Transport for NSW, and the Rural Fire Service
- Delivers a single, consolidated response covering all relevant agency positions rather than multiple separate responses
- Is subject to a mandatory 28-day timeframe to provide that response from the point of referral
- Must answer a Consent Authority’s enquiry about whether a formal referral is even required within 2 business days
That 2-business-day pre-check is worth attention. Under the old system, determining whether a particular trigger was engaged often required either a formal referral or a protracted back-and-forth with an agency. The ability to get a confirmed answer within 2 business days on whether a referral is required at all could save weeks of unnecessary process on marginal cases.
The Environmental Planning and Assessment Regulation 2021 is being amended to give the DCA its powers. The term “approval body” in the existing regulation is being replaced with DCA references, and a single consolidated set of provisions establishes the process for consent authorities seeking state input on DAs and modification applications.
What the Development Coordination Authority Means for Subdivision and Development Applications
The DCA reform primarily affects Development Applications that require State agency input. Understanding exactly where it applies, and where it does not, which matters for how you plan and sequence your projects.
DA Pathway Subdivision Projects
For subdivision projects proceeding via council DA, the DCA changes how State referral obligations are discharged during assessment. Projects that previously required direct referrals to Transport for NSW (for road access), Water NSW (for drainage and catchment issues), the Rural Fire Service (for bushfire-prone land), or Heritage NSW will route through the DCA instead.
In practical terms, this means one point of lodgement for State input, one coordinated response, and one 28-day clock rather than multiple separate processes running out of sync with each other. Conflicts between agency positions, which under the old system could surface late and delay determinations are resolved inside the DCA before the consolidated response goes to the consent authority.
For larger civil subdivision projects, this change is significant. Having issued subdivision works certificate approvals across projects ranging from 2-lot infill subdivisions through to 134-lot residential stages and 301-dwelling sites across 35+ NSW councils. At that scale, multiple referral obligations are routine. Transport for NSW on road interfaces, Water NSW on drainage, the RFS on bushfire constraints, each was previously a separate relationship running on its own timeline. From July 2026, all of that feeds through one coordination point with a capped response window.
What the DCA Does Not Cover
The DCA does not affect the Complying Development Certificate pathway. Complying development bypasses the DA process entirely, operating under the Housing SEPP 2021 and the Low Rise Housing Diversity Code. There are no state agency referrals in the CDC pathway, so the DCA has no role there.
The DCA also has no involvement in the functions of a Registered Subdivision Certifier. A Certifier’s role in issuing Subdivision Certificates and Subdivision Works Certificates sits outside the DA referral framework. If you want to understand what a Subdivision Certificate involves and how it sits in the broader approval sequence, that is a separate question from the DCA reforms.
The Consent Authority function does not change either. Your Council or the Planning Secretary still determines the DA. The DCA coordinates the state input that informs that determination, it does not make it.
How to Prepare Before July 2026
The DCA launch is less than three months away as of the date of this article. For project teams with DAs currently in assessment or about to be lodged, there are practical steps worth taking now.
Audit Your Referral Position
For any DA currently in assessment, identify which State agencies are triggered under the existing instrument framework. Understand whether your application will be assessed under the old framework, the new DCA framework, or a transitional position depending on where your project sits in the assessment process at 1 July 2026.
This is not a question to leave until July. Projects mid-assessment at the changeover date need clarity from their Town Planner on how the transition applies to their specific lodgement. Assuming the new framework will automatically apply to everything from 1 July without checking the transitional provisions is a risk.
Review Your Program Assumptions
If you are programming a DA pathway subdivision or development project for the second half of 2026, the DCA’s 28-day referral window should be your planning anchor for State agency response time. That is a significant potential improvement over current practice, where a single referral could realistically add two months and multiple referrals could add considerably more.
That said, apply implementation risk to your program. Structural reforms of this scale take time to bed down. Agencies are being absorbed into a new coordination framework, staff are working to new processes, and early applications will test the system in ways that are hard to predict before launch.
Build your program around the 28-day window as the target, but maintain schedule contingency for the first few months of operation.
Get Advice on Your Specific Triggers
Not every project will be affected equally. A straightforward dual occupancy subdivision under the CDC pathway has no DCA exposure at all. A larger DA pathway subdivision in a bushfire-prone area near a classified road with drainage crossing a Water NSW-regulated catchment has significant referral exposure, and will benefit most from the DCA consolidation.
Understanding your specific trigger profile before lodgement is the most commercially useful thing your project team can do right now. Your Town Planner should be able to map this clearly before your DA goes in.
FAQ: NSW Development Coordination Authority
Does the DCA replace my council as the consent authority?
No. The DCA coordinates State agency input only. Your Council or the Planning Secretary remains the Consent Authority and makes the final determination on your Development Application. The DCA’s role is limited to consolidating the state-level concurrences, referrals, and general terms of approval that feed into that decision.
Which state agencies does the DCA cover?
The DCA brings together experts from up to 14 NSW Government agencies, including Water NSW, Transport for NSW, and the Rural Fire Service. The specific agencies covered are confirmed through the amendments to the Environmental Planning and Assessment Regulation 2021, which replace individual agency referral provisions with a single DCA process. Heritage NSW is also included via the agency performance framework.
Does the DCA affect complying development certificate applications?
No. CDC applications do not go through the DA referral pathway. The DCA reform is specific to DA concurrences, integrated development referrals, and general terms of approval. If you are pursuing a complying development certificate for a dual occupancy subdivision or other low-rise housing, your pathway and certification process are unaffected by the DCA changes.
When do I need to start factoring the DCA into my project program?
From 1 July 2026, the DCA framework applies to all new DAs lodged that trigger State agency input. If you are lodging a DA in the second half of 2026, plan to the DCA process from the outset. If your DA is already in assessment, confirm with your planner whether transitional provisions apply and how the changeover date affects your assessment timeline.
What This Reform Means in Practice
The DCA is not a marginal administrative adjustment. Consolidating more than 800 referral triggers from 175 planning instruments into a single process with a mandatory 28-day response window is a material change to how development applications are assessed in NSW.
The commercial case is clear. If the reform operates as designed, development teams should see more predictable referral timeframes, fewer conflicting positions emerging late in the assessment process, and a faster path to determination on DA-pathway projects.
The practical reality is that structural reforms of this scale always involve a bedding-in period. The agencies being absorbed into the DCA model are moving from independent processes to a coordinated one. That takes time, and the first months of operation are likely to surface implementation issues that are difficult to anticipate from the outside.
The right response is not to ignore the reform or assume it will not affect your projects. It is to get clear advice now on your referral exposure, adjust your program assumptions for July 2026 onward, and make sure your project team understands the new process before you lodge.
