The Wilman Wadandi Highway is a ring road around the city of Bunbury, Western Australia which was completed in December 2024.

[2] Formerly known as the Bunbury Outer Ring Road (or BORR), it was renamed in October 2024 after the Wilman and Wadandi Indigenous Australian peoples that originally lived in the area.

Heading east from the future interchange is Clifton Road, which leads to the town of Brunswick Junction.

Following that, the WWH will cross over the South Western Railway and then bend to the west, coming to an at-grade intersection with Discovery Road.

[6] The first stage of the BORR received $15.8 million in funding in the 2010 state budget for land acquisition and pre-construction activities.

The contract for this was awarded to Fulton Hogan at a cost of $133.9 million, jointly funded by the federal and state governments.

The plans at the time had the road be built to a freeway standard with grade separations at all junctions.

[17] In March 2020, two consortia were shortlisted: the Forrest Alliance, comprising CPB Contractors, Carey MC, Densford Civil, GHD and BG&E; and Southwest Connex, comprising Acciona, NRW Contracting, MACA Civil, AECOM and Aurecon.

[19][20] In April 2020, a contract for early works, including earthworks, fencing and planting, was awarded to Fulton Hogan.

[21][22] Southwest Connex was chosen as the preferred proponent in August 2020,[23][24] and they were awarded the contract in October 2020, now known under the name of South West Gateway Alliance.

[25] The design of the interchange with South Western Highway was modified to allow movements in all possible directions as part of a redesign released in December 2019.

[27][28] The federal government revealed it would spend an additional $320 million on the project in its March 2022 budget due to labour shortages and an increase in the cost of raw materials.

[30][31] Stage three was controversial as it cut into the habitat of the critically endangered western ringtail possum.
