Fire in the bush (Eva Johnstone)
Blue Mountains – Still Not Another Suburb of Sydney
142–150 Narrow Neck Road, Katoomba
Latest News - 25 July 2026

Your reason matters

People have supported the Narrow Neck campaign for many different reasons. For some it’s bushfire risk and evacuation. For others it’s protecting endangered swamps and waterways or ensuring local planning protections are not overridden by the Housing Delivery Authority (HDA) pathway.

Whatever your reason, we’re encouraging you to share it with the NSW Minister for Planning and Public Spaces in your own words. Personal letters help reinforce the breadth of community concern and remind the Minister that people across the Blue Mountains care deeply about the future of this special place.

If you haven’t already done so, download our Letter Writing Guide for suggested points, instructions and contact details, then send your letter during July.

Campaign against HDA fast-track development at Narrow Neck Road, Katoomba

The Blue Mountains is a place of outstanding natural beauty. Our National Park is World Heritage-listed, our townships have a unique character, and our communities have worked tirelessly for decades to protect the environment, through careful local planning.

Now, an unprecedented planning shortcut threatens to override critical environmental protections and permanently change the Blue Mountains as we know it.

The NSW Government’s new Housing Delivery Authority (HDA) is being used to fast-track housing developments. For the first time in the Blue Mountains, a developer is seeking approval under this pathway for a large-scale, high-density project at 142–150 Narrow Neck Road, Katoomba - a proposal that far exceeds the limits set in the Local Environmental Plan (LEP) and Development Control Plan (DCP).

The proposal:

The proposal is to rezone land to allow:

This was approved as a State Significant Development and the Department of Planning, Housing and Infrastructure issued its Secretary’s Environmental Assessment Requirements (SEARs) in June 2025. The Environmental Impact Statement (EIS) is currently being prepared but will only be on exhibition for 14 days.

Why this matters:
The Society supports appropriate housing that aligns with local planning rules and the Blue Mountains LEP. This proposal, however, sets a dangerous precedent for our community and our future.

Key concerns include:

This is not just about one development. If the HDA pathway is allowed to proceed in the Blue Mountains, it opens the door for similar high-density projects across our towns - potentially changing the region forever.

Our Call:

We are calling for this development not to be approved, and that the Blue Mountains Local Government Area to be excluded from the HDA pathway.
