Since 2022, we have been working with landowners, government and the development industry to shape the frameworks and principles that guide how we will manage stormwater across the Aerotropolis and Mamre Road areas.

So far, in consultation with industry and stakeholders, we’ve finalised key documents that will guide development in the area, including Stormwater Scheme Principles and a Developer Works Policy.

The stormwater planning for the Mamre Road area has also progressed, with the recent public display of the Mamre Road Integrated Stormwater Development Servicing Plan (DSP), which should be finalised in the first half of 2025.

We’ve now developed the draft scheme plans for the Wianamatta Badgerys and Cosgroves, and we would like your ffeedback on these.

After the exhibition period closes on Monday 5 May, we’ll consider your feedback. We’ll then make any necessary changes to the schemes and summarise our responses in a Consultation Outcomes Report, which will be published on our website.

Once the schemes for Wianamatta Badgerys and Cosgroves are finalised—in mid-2025—we’ll use them to draft Development Servicing Plans (DSPs). You’ll have a further opportunity to comment on these, and

we’ll keep landowners and key stakeholders informed as the project progresses.

At the same time, we’ll continue to develop the scheme plans for other areas in the Aerotropolis, such as the Duncans Mulgoa area. We’re planning to share a draft later in 2025.

Draft DSPs for Wianamatta Badgerys and Cosgroves are expected to be completed later in 2025, then finalised in early 2026.
