Project Description

The Bunbury Port Access Road (Stages 1 and 2) and the Bunbury Outer Ring Road (Stage 1) were constructed to provide an efficient and safe road link to the Bunbury Inner Harbour and to separate heavy vehicles accessing the Port from local traffic in the City of Bunbury.

Delivery of the project was divided into two components:

  • Bunbury Port Access Road (Stage 1): The Bunbury Port Access Road has been constructed from Estuary Drive near Bunbury Port to the South Western Highway (north) near Picton;
  • Bunbury Port Access Road (Stage 2) and Bunbury Outer Ring Road (Stage 1): The Bunbury Port Access Road was extended from the South Western Highway (north) to Stage 1 of the Bunbury Outer Ring Road, which links the Picton Boyanup Road and the South Western Highway (south).

A savings-funded scope variation to the second component enabled construction of a road train assembly area for Bunbury.


Freight and other traffic volumes have risen significantly in recent years and will continue to increase rapidly.

The Bunbury Port Access Road will provide a direct link between the Bunbury Inner Harbor and the industrial areas to the south east of the port at Picton.  Construction of the Port Access Road, including a link to the Australind Bypass now provides:
  • a more direct route to the Port for heavy vehicles and vehicles travelling north on the South Western Highway and the Kwinana Freeway Extension – Forrest Highway;
  • a more direct route for vehicles travelling from the south on the Boyanup Picton Road (trucks are expected to divert from the South Western Highway south to the Boyanup Picton Road at Boyanup);
  • a more direct route between the Port and the Picton Industrial Area;
  • efficient access to the Kwinana Freeway Extension – Forrest Highway from Picton and, with the Kwinana Freeway Extension – Forrest Highway, will provide a safer and more efficient route to Perth and thus reduce heavy traffic utilising the South Western Highway to the north;
  • a reduction in the volume of heavy traffic on Robertson Road and associated intersections; and
  • improved freight efficiency into and out of the Bunbury Port Inner Harbour.
The Bunbury Outer Ring Road will attract heavy vehicle traffic away from the existing Bunbury inner ring road, facilitating freight access.


The Australian Government provided $123.6 million to this $154.6 million project, in partnership with the Western Australian Government.


Construction of the Bunbury Port Access Road (Stage 1) commenced in January 2009 and was completed in February 2010.

Construction of the Bunbury Port Access Road (Stage 2) and Bunbury Outer Ring Road (Stage 1) commenced in February 2012 and was complete in July 2014, when the road train assembly area was opened for use.
