Wilman Wadandi Highway (Bunbury Outer Ring Road Project)

The Wilman Wadandi Highway opened to traffic in December 2024 and is already delivering significant benefits to the South West Region. As the largest transport infrastructure project in the region, the highway is improving travel times, enhancing safety and supporting a more reliable network for locals, tourists and freight operators. The project has unlocked a range of benefits, including:

• Improved freight efficiency
• Reduced local congestion and create more reliable journey times for all road users
• Added sustainable infrastructure to support Greater Bunbury’s position as an industrial hub for the South West Region
• Generated long term job opportunities for locals through local employment programs
• Reduced travel time between the north and south of Bunbury
• Improved access to Bunbury Port as well as existing and proposed industry areas east of Bunbury 
• Vehicles now travelling between Bussell Highway and Forrest Highway to avoid 13 sets of traffic lights and one rail level crossing
• Provide travel savings of between 11 and 18 minutes, depending on the destination and peak traffic conditions along the alignment
• Extending the service life of existing arterial roads, currently used by trucks, minimising future local upgrade treatments required
• Reducing the need for heavy vehicles to mix with local traffic on local roads by redirecting 10,000 to 15,000 vehicles a day onto the new road

During construction we:

• Exceeded procurement targets, with over $690 million spent across 380+ local and Aboriginal businesses
• Created training and job opportunities for entry level positions through the Yaka Dandjoo program

We employed the services of KPMG to quantify the project’s direct contribution to the South West region’s economy, find out more by reading their Local Economic Impacts Summary.

 Funding

The Wilman Wadandi Highway (previously known as the Bunbury Outer Ring Road (BORR)) will deliver significant benefits to the region, including time saving, road safety, freight efficiency and improved port access.

A significant portion of the funding from the project’s $1.46 billion is being spent within the region, creating further local jobs, business opportunities and supporting local economic growth.

The $1.46 billion project is jointly funded by the Australian and Western Australian Governments, with the increased investment aligning with the project’s scale and complexity, reflecting the current market pressures.

We have made a series of sustainability commitments on the project. Some of these commitments include:

Employment, training, and local business

• Giving new opportunities by targeting 10 per cent of the workforce to be previously unemployed.
• Creating sustainable workforces for local businesses
• Collaborating with TAFE and other local training organisations

Construction

• Minimising waste generation and maximising reuse and recycling using sustainable products
• Sourcing materials from local businesses to reduce transport distances and emissions
• Utilising local recycling facilities
• Seeking to use renewable energy options when sourcing construction equipment

Environment

• Salvaging valuable vegetation from areas to be cleared such as orchids, grass trees and zamia palms
• Constructing fauna underpasses and overpasses in line with environmental regulators’ requirements that cannot be used by vehicles and offer shelter to possums from predators and allow for dense vegetation planting

Aboriginal Heritage and Culture

• Working closely with Aboriginal heritage monitors to identify significant areas or items and promote heritage values
• Creating urban design outcomes that include significant Aboriginal cultural components, such as integrated artwork, interpretive signage, naming of project aspects, trails, and nodes
