Outer Sydney Orbital Stage 2

Reviewed

The Outer Sydney Orbital Stage 2 (OSO2) originates at the M31 Hume Motorway at Menangle and continues to the Illawarra-Shoalhaven region.

Outer Sydney Orbital 2

OSO2 covers areas containing ecologically and culturally sensitive Aboriginal sites, as well as complex urban and semi-rural regions. Transport for NSW continues to engage with the Dharug and Dharawhal communities, to ensure that we work with sites sensitively, now and in the future.

More about OSO2 – community consultation

Note: This section contains references to the traumatic 1916 Appin events.

Transport exhibited two shortlisted corridor options for public consultation between November 2020 and January 2021. With the help of the community and Heritage NSW, sensitive locations associated with the Appin Aboriginal massacre site were identified.

Transport published the OSO 2 Consultation Report which documents the submission themes we received. 

We are also careful to consider other factors that impact OSO2 – see Koala Habitat Protection and the Cumberland Plain Conservation Plan for more information.

Key benefits

  • Reducing travel times between Western Parklands City and the Illawarra-Shoalhaven region
  • Reducing the cost of moving freight between Port Kembla, (Illawarra region) the Western Sydney International Airport Precinct and broader Western Sydney
  • Increasing transport capacity, potentially reducing delays, and offering an opportunity to improve road safety outcomes in line with the Government’s Towards Zero vision
  • Reducing congestion at the Picton Road interchange
  • Creating a well-planned regional road and transport network
  • Protecting the historic Appin and Wilton Town Centres from through traffic. 

What’s happening now

We have responded to community needs. In August 2021, we changed the preferred location of this future corridor, to minimise the impacts on culture, heritage and the environment.

Next steps

We will share updates as they become available.

Acquisitions

There is no need for Transport to acquire land until close to the time the transport infrastructure is required. In the meantime, landowners can continue to live on and use their land. For more information on property acquisition, see Property Acquisitions on the Corridors home page.
