This audit assessed whether planning processes and early works have adequately prepared the Melbourne Metro Tunnel Project for the main tunnel and stations works.
We reviewed planning processes including the development of the project business case (defining the problem, strategic options analysis, demand forecasts, and benefits definition), stakeholder consultation, site acquisition and preparation, land clearance and demolitions, environmental effects studies and other statutory planning.
We examined whether the Melbourne Metro Tunnel business case showed adequate understanding of the problem the project is intended to solve, and whether the reference design for the Melbourne Metro Tunnel demonstrates a flexible future-proofed solution, informed by robust passenger demand modelling.
We also examined whether the environmental effects study and statutory planning processes adequately considered the environmental risks and impacts of the project. Progress of early works activities was also examined in detail to determine whether they had been delivered within the expected time, cost, scope, quality and environmental performance parameters.
We made 11 recommendations—six for the Department of Transport (DoT), three for the Department of Premier and Cabinet (DPC), the Department of Treasury and Finance (DTF) and DoT jointly, one for DPC and DTF jointly, and one for the Department of Environment, Land, Water and Planning.
