A corridor is a strip of land used for transport or other major infrastructure. Corridor protection is the process of reserving these strips of land for future transport or major infrastructure needs.


In Western Sydney, new major infrastructure corridors are needed to serve the future Western Parkland City including new jobs, homes and growing industries around the Western Sydney Airport and the surrounding business area. These corridors also serve as important links to other regional centres in NSW, connecting industries, communities and employment areas across the state.


In 2018, Transport for NSW (TfNSW) consulted on five recommended corridors for future transport infrastructure to support the growing population of Western Sydney. Community feedback was sought on a Discussion Paper on the proposed State Environmental Planning Policy to protect Western Sydney Corridors.


The protection of three of the corridors, the North South Rail Line (providing for the future Sydney Metro – Western Sydney Airport), South West Rail Link extension and Western Sydney Freight Line (Stage One) has now been achieved through the making of the State Environmental Planning Policy (Major Infrastructure Corridors) 2020 (SEPP).


A corridor for the future Outer Sydney Orbital (Stage One) is still under consideration by the NSW Government.


What does this mean?

The State Environmental Planning Policy (Major Infrastructure Corridors) 2020:

  • identifies infrastructure corridors that have been protected and the land that the SEPP applies to
  • reserves land within these corridors for infrastructure purposes through the rezoning of land, and identifies it as a major infrastructure corridor
  • changes the planning controls that apply to land within the corridors, including identifying development that will be permissible within the corridor
  • maintains the structural integrity of the land for future infrastructure by requiring additional consideration for certain excavation works on adjacent land
  • guides development on land surrounding the corridors.
