Port Augusta to Perth - Western Australia

Funding Program:Roads of Strategic Importance
Status:In planning
Transport Mode:Road
Estimated Project Cost:$62,500,000
Australian Government Contribution:$50,000,000

Project Description

The Port Augusta to Perth corridor is approximately 2,388km long and comprises the Eyre Highway, Great Eastern Highway and Coolgardie-Esperance Highways.

The key arterial roads connecting to the corridor include the Esperance Highway and the Albany Highway in WA and the Flinders Highway and Augusta Highway in SA.

The project will include targeted upgrades to widen, strengthen and realign various sections along the corridor to improve the flow of vehicles and increase access for higher efficiency heavy vehicles.


The project will:

  • Improve road safety
  • Improve freight efficiency, connectivity and travel time
  • Ensure consistent Restricted Access Vehicles (RAVs) ratings across the network, which will provide improved access for agricultural and mining regions to transport hubs


The Australian Government has committed $150 million towards the Port Augusta to Perth Corridor, of which $100 million has been committed to South Australia and $50 million to Western Australia.


The project is in planning.
