What the New Development Coordination Authority Means for Your NSW Development Application

On 1 July 2026, the NSW planning system changed in a way that will affect almost every development application that needs input from a state government agency. The Development Coordination Authority, or DCA, is now fully operational, and it replaces one of the most frustrating parts of the DA process: waiting on multiple agencies to weigh in before a council can move forward.

What Is the Development Coordination Authority (DCA)?

The Development Coordination Authority is a new one-stop-shop for NSW Government input on development applications, modification applications, and rezonings. Instead of an applicant or council having to seek advice separately from up to 22 different state agencies, the DCA now acts as a single point of contact and issues one coordinated response.

If your project needs sign-off from agencies covering things like transport, water, biodiversity, or bushfire, the Development Coordination Authority is now the body pulling that advice together, rather than you or your council chasing each agency individually.

Why the Development Coordination Authority Was Created

Referrals to multiple agencies have long been one of the biggest sources of delay in the NSW DA process. Under the old system, each additional agency referral could add around 100 days to an assessment. With several referrals often required on a single project, that delay compounded fast.

The Development Coordination Authority was set up to fix this by consolidating more than 800 separate referral requirements, spread across 175 different planning instruments, into a single, simplified list. The number of situations that trigger a referral has also been cut by close to 90 per cent, down to fewer than 50 triggers. Referrals for sensitive matters like environmental protection, heritage, and bush fire management are still safeguarded, but a lot of the unnecessary, duplicated referrals have been removed.

How the Development Coordination Authority Changes DA Assessment Timeframes

The headline change is speed. Where a project used to wait on separate responses from each relevant agency, one at a time, the Development Coordination Authority is now required to deliver a single, coordinated government response within 28 days.

The DCA also has a role after consent is granted, helping resolve post-consent issues on larger housing projects so construction can start sooner rather than stalling on outstanding conditions.

It's still very early days. The DCA only took on its full statutory powers this month, so how consistently these 28-day timeframes hold up in practice, and how councils and agencies adjust to the new referral list, is something worth watching over the next few months.

What This Means for Your Next Development Application

If your project is the kind that typically triggers state agency involvement, integrated development, land near a transport corridor, sites with heritage or bushfire overlays, this is a meaningful shift in how long that part of the process should take. It doesn't remove the need for a well-prepared application. If anything, a clear, well-documented DA that addresses the right issues upfront still matters, because the DCA is coordinating existing referral requirements, not lowering the bar for what needs to be demonstrated.
