Outer Sydney Orbital Stage 2 corridor identification


Project overview

The Outer Sydney Orbital Stage 2 corridor investigation is identifying long-term transport connections between Western Sydney and the Illawarra-Shoalhaven region.

Investigations for the Outer Sydney Orbital Stage 2 will be undertaken in three sectors:

Sector 1: between the Hume Motorway and Appin Road, south east of Appin Village and between the Hume Motorway and Picton Road.

Sector 2: Appin and Picton Road corridors for potential upgrade through WaterNSW’s water catchment area (Metropolitan Special Area).

Sector 3: Illawarra Connections – a potential new Illawarra Escarpment crossing.

Key benefits

  •  Provide communities with transport connections between the Western Parkland City and the Illawarra-Shoalhaven region.
  • Provide access to jobs and other employment opportunities across the Aerotropolis and surrounding industrial lands. 
  • Provide access to the Western Sydney Airport. 
  • Support different transport needs including public transport, walking and cycling options. 
  • Enable freight to move efficiently and safely.
  • Support urban development across the Wilton and Greater Macarthur Growth Areas and the Illawarra-Shoalhaven region. 
  • Facilitate great places, and provide certainty for investment across the region.

Current Status

The community consultation period is now closed and Transport for NSW (TfNSW) is reviewing the community’s feedback and refining the corridor options.

We will summarise comments and questions received during our public consultation before publishing our responses in a Community Consultation Report. We will use the feedback received to help select a preferred option for the Outer Sydney Orbital Stage 2 Corridor.

In addition, TfNSW is continuing to work closely with other agencies, including the Department of Planning, Industry and Environment, on a number of important issues in the Greater Macarthur Growth Area, including:

  • Protecting koala corridors and providing habitat revegetation;
  • Implementing the recommendations of the Chief Scientist and Engineer report, Advice on the protection of the Campbelltown koala population; 
  • Aligning strategic planning to the draft Cumberland Plain Conservation Plan;  and
  • Adopting the Government Architect’s recently released Connecting with Country Framework

While this work continues, a Technical Assurance Panel (TAP) pilot program, which was established by the Department of Planning, Industry and Environment for two precincts in the Greater Macarthur Growth Area (Appin and Gilead), has been temporally placed on hold.

The TAP is a new way for state agencies, councils and landowners to work together to undertake strategic investigations for precincts. The pilot aims to ensure the development proponent addresses key local, state and strategic issues, before the lodgement of any formal rezoning proposal.

TfNW will keep the community informed of any updates as its work with agencies on koala protection and other issues in Greater Macarthur progresses. Additionally, TfNSW will publish the Community Consultation Report for the Link Road on the project website, once it is finalised.

Community Consultation

Consultation is now closed for the Outer Sydney Orbital Stage 2 corridor options between the Hume Motorway and Appin Road. This consultation was held between 16 November 2020 and 29 January 2021.

Currently, the project team is reviewing all submissions made during the consultation period.
