Certain infrastructure is deemed to have State significance due to the value or potential impacts that it will have. State Significant Infrastructure (SSI) is a project that is:

  • Declared to be SSI by the State Environmental Planning Policy (State and Regional Development) 2011 OR
  • An activity for which the proponent is a public authority and is also the determining authority and which require an environmental impact statement OR
  • Otherwise declared by the Minister for Planning as SSI.
  • A Proponent must demonstrate their proposed project is SSI when lodging their application with supporting documents. This documentation must contain sufficient information about the proposal and its environmental impacts.

The Department’s assessment and recommendations will be set out in the Environmental Assessment Report. The Report and recommendations are referred to the Minister for Planning for consideration in making his determination.

Roads and Maritime Services (RMS), is seeking approval for the construction and operation of a new multi-lane road link between the New M5 Motorway at Arncliffe and President Avenue at Kogarah, which would include:

  • north- and south-bound motorway tunnels around four kilometres in length
  • a tunnel portal at Brighton-Le-Sands connecting to entry and exit ramps at a widened President Avenue
  • stub tunnels for the proposed connection to a future southern stage of the F6 Extension
  • upgrade of the President Avenue and Princes Highway Intersection
  • ancillary infrastructure and operational facilities
  • provision of new pedestrian and cycle pathways
  • new service and modified existing service utilities, including a power line from Earlwood to the proposed Rockdale Motorways Operation Complex
  • lane-marking of an additional two lanes in each carriageway of the New M5 tunnels, resulting in four lanes in each carriageway between the St Peters Interchange to the connection with the F6 Extension Stage 1 tunnel at Arncliffe.

The F6 Extension Motorway program is a proposed new, multi-lane road link between the New M5 Motorway at Arncliffe and the Princes Highway at Loftus.


The F6 Extension Stage 1 is proposed to be a four-kilometre continuous twin tunnel (north and south) which will connect the New M5 Motorway at Arncliffe to President Avenue, Kogarah. The F6 Extension Stage 1 will be designed with a provision for a future extension south.

  • The Department has published all submissions received and asked RMS to address issues raised in submissions by the community, council and government agencies.
  • RMS will prepare a formal Response to Submissions (RtS) report, which we will make publicly available.
  • The Department will then assess the project, which includes consideration of the EIS, all submissions and community feedback, and the RtS.
  • The Department will make a recommendation to the Minister for Planning for his determination.
  • Once a final decision has been made, the Department will notify RMS and relevant government agencies and councils of the outcome and publish a Notice of Decision on our website which outlines the matters taken into consideration in making the decision and reasons for the decision.
