Delivering Westconnex

On 31 August 2018, the NSW Government announced a 51 per cent stake in Sydney Motorway Corporation was awarded to Sydney Transport Partners - a consortium led by Transurban.
The NSW Government retains a 49 per cent residual stake.

We are working closely together and with our industry partners to successfully deliver the project, on time and on budget.

The NSW and Federal governments have undertaken extensive planning and investigations to inform their investment in WestConnex. The updated Strategic Business Case released in November 2015 outlines a Benefit to Cost Ratio (BCR) of 1.88:1 meaning for every dollar invested in the delivery of the project, $1.88 will be returned to the NSW economy.

WestConnex will deliver a wide range of benefits, including valuable time savings for road users and productivity gains for freight and commercial operators both critical components of our growing NSW economy.

Our innovative financing approach involves partnering with the private sector to keep the cost to the NSW Government and taxpayers to a minimum. Under the current financing arrangements, government is contributing just a third of the total value of the project. On 12 May 2017, the NSW Government announced it would proceed with the sale of at least a 51 per cent stake in the Sydney Motorway Corporation to help fund the M4-M5 Link. On 31 August 2018, the NSW Government announced the 51 per cent majority stake in Sydney Motorway Corporation was awarded to Sydney Transport Partners.

The Government’s investment in constructing WestConnex will be returned when the project is sold, to be used on other critical infrastructure projects, including public transport.

Ultimately, people using the motorway and paying tolls will fund the project. Distance-based tolls apply on the new M4 between Parramatta and Homebush, as the project is open to traffic. Motorists will only pay for the section of motorway they use, and tolls will be capped. There will always be a free alternative route.

WestConnex comprises six individual projects each of which has been subject to an independent gateway assurance review process by Infrastructure NSW which then provided its recommendations to the NSW Government for consideration prior to granting approval to proceed.

The Strategic Business Case for the WestConnex program of work was prepared and assessed in 2013. An Executive Summary of the Business Case was publicly released at that time.

An Updated Strategic Business Case was published in November 2015, and was subject to an externally managed Business Case Gateway Review, as part of the Infrastructure Investor Assurance Framework.
