The WestConnex Community Reference Groups (WCRGs) provide a forum for discussion and feedback between the WestConnex project team and representatives of the community, stakeholder groups and local councils on matters relating to WestConnex projects. With the completion of the New M4 Tunnels, the WCRGs have changed to include the communities and stakeholders impacted by the M8, the M4-M5 Link Tunnels and a separate group for the Rozelle Interchange.

The WCRG (M4-M5 Link Tunnels and the M8) is held with community members representing the suburbs of Leichhardt, Haberfield, St Peters, Glebe and Camperdown. Representatives from the City of Sydney, Inner West, Canada Bay and Strathfield Councils and the Department of Planning, Industry and Environment also attend. Representatives from Transport for NSW include members of the senior project and stakeholder engagement teams.

If you have any questions or would like to submit an application to be part of the WCRG, please see the full terms of reference and contact wcrg@transport.nsw.gov.au or contact Transport for New South Wales (Mon-Fri 8:30am-5pm) via 1800 660 248 and ask to speak to the community engagement team.

Tunnelling is a safe and frequently used construction technique that significantly reduces impacts on local properties while still enabling major infrastructure to be delivered in built-up residential areas. During construction of the M4-M5 Link Tunnels, strict safety requirements are adhered to in the design, construction and operation of the tunnels and every effort is made to minimise impacts within local area.

Most construction work will take place underground, with tunnelling activity taking place 24-hours a day, seven-days a week. The impact on properties above the tunnel is expected to be minimal and temporary. For more information on tunnelling, please refer to our tunnelling fact sheet.

Properties within 50 metres of the tunnel alignment will be offered a property condition survey prior to the start of work in an area. Before work starts in your area the contractor will contact eligible properties. For further information regarding property condition surveys, please refer to our Property Condition Survey fact sheet.

All work notifications can be found in the Document Library.
