This audit assesses the assurance provided to the NSW Government for the initial stages of the WestConnex project.

The audit examined the WestConnex project from concept development to the pre-tender phase for Stage 1A – M4 (Parramatta to Homebush Bay). It did not examine the merit of the project or whether it represented value-for-money.

This audit found a number of shortcomings with the governance of the WestConnex project during its early stages and makes recommendations on how to better govern the remainder of the project to minimise the risk of failure.

In our opinion the Government’s ‘no net cost to government’ requirement was a legitimate (but not the only possible) basis for the tunnel bid process. The Government was entitled to decide that tunnel users meet the tunnel costs. Structuring the bid process on the basis of an upfront reimbursement of costs incurred (or to be incurred) by the Roads and Traffic Authority (RTA) was therefore appropriate.

In our opinion, however, the Government, Treasury and the RTA did not sufficiently consider the implications of an upfront payment involving more than simple project cost reimbursement (i.e. the ‘Business Consideration Fee’ component). In addition, the RTA was wrong to change the toll escalation factor late in 2002 to compensate the tunnel operator, Cross City Motorway Pty Ltd, for additional costs.
