Three major construction consortia have been shortlisted to develop plans for around 35km of twin-bore tunnelling on Australia’s proposed Newcastle–Sydney High Speed Rail project. The High Speed Rail Authority (HSRA) has selected the teams for an Early Contractor Involvement (ECI) process covering Area Package 1, between Berowra and Ourimbah, as the project progresses through its Development Phase.
The shortlisted consortia are:
- Acciona John Holland Joint Venture
- Advanced Alliance Joint Venture – Gamuda Engineering, FCC Construction Australia and Samsung C&T Corporation
- GoFar Joint Venture – CPB Contractors, Ferrovial Construction (Australia) and VINCI Construction Grands Projets Australia
The three teams will compete during the ECI phase to develop construction plans and refine costs, programme, design and delivery methodology for the package.
Area Package 1 includes approximately 35km of twin tunnels between Berowra and Ourimbah, to be excavated using TBMs. The scope also includes construction of the Central Coast High Speed Rail Station at Gosford and installation of rail and station systems, together with associated structural and surface infrastructure.
According to HSRA, the ECI process will examine issues including tunnel diameter, TBM requirements and construction methodology, as well as the design and delivery of the Gosford station.
The shortlisted teams bring Australian and international high-speed rail, tunnelling and major infrastructure experience to the project.
An advanced manufacturing facility is also being considered as part of the delivery strategy. The facility would use automation, robotics and precision manufacturing to support railway construction and provide opportunities for Australian manufacturers and suppliers.
HSRA chief executive Tim Parker said Australia’s tunnelling sector had developed considerably over the past 15 years.
“Over the past 15 years, Australia has developed a world-class tunnelling industry with hundreds of kilometres of tunnels built here – now we’ll be working with some of the best of the best on Australia’s High Speed Rail,” Parker said.
He described the ECI procurement as a “critical next step” in the Development Phase, with the teams set to investigate “the diameter of the tunnels we will build for Australia’s first high speed trains, what kind of mega tunnel boring machines we need and how we build the first high speed rail station at Gosford”.
Infrastructure and Transport Minister Catherine King said the competitive process would be used to identify the most efficient approach to the tunnelling works.
“The three consortia will determine the best and most innovative ways to drive tunnels between Berowra and Ourimbah, while ensuring Australians get value for money,” she said.
The proposed dedicated high-speed railway is intended to reduce Newcastle–Sydney journey times to around one hour, while journeys from the Central Coast to either Newcastle or Sydney would take approximately 30 minutes.
No major construction contract will be awarded until the Australian Government completes its investment decision-making process at the end of the Development Phase.
Subject to that decision, one of the three shortlisted consortia would subsequently be selected by HSRA to deliver the Area Package 1 tunnelling and associated construction works.

Executive Summary
Three construction consortia have been shortlisted for the Early Contractor Involvement (ECI) process related to the Newcastle–Sydney High Speed Rail project, focusing on Area Package 1 between Berowra and Ourimbah. The selection was made by the High Speed Rail Authority (HSRA). The shortlisted teams are Acciona John Holland Joint Venture, Advanced Alliance Joint Venture (comprising Gamuda Engineering, FCC Construction Australia, and Samsung C&T Corporation), and GoFar Joint Venture (comprising CPB Contractors, Ferrovial Construction (Australia), and VINCI Construction Grands Projets Australia).
The ECI phase will allow these teams to develop construction plans and refine cost, programme, design, and delivery methodology for the package. Area Package 1 involves approximately 35km of twin tunnels using Tunnel Boring Machines (TBMs) between Berowra and Ourimbah, along with the construction of the Central Coast High Speed Rail Station at Gosford and associated systems. The ECI process will examine technical aspects such as tunnel diameter, TBM requirements, construction methodology, and the design and delivery of the Gosford station.
The project also involves considering an advanced manufacturing facility utilizing automation for railway construction. The process is intended to identify the most efficient approach to the tunnelling works, aiming to determine optimal methods for building the tunnels and the station while ensuring value for money. A final major construction contract will only be awarded after the Australian Government completes its investment decision-making process.
Full Take
The process highlights a critical tension between large-scale infrastructure ambition and the need for rigorous, competitive risk management in complex engineering. The move to an ECI framework, where potential delivery methods (tunnel diameter, TBM type, station design) are actively negotiated with shortlisted consortia before final commitment, shifts the focus from selecting a single contractor to co-developing the optimal technical pathway. This structure implicitly acknowledges that the risks associated with tunnelling—geological uncertainty, machine performance, and interface management—are too high for traditional, fixed-price contracting alone. The inclusion of international firms suggests an acceptance that novel or highly specialized delivery methodologies may be necessary to meet ambitious timelines.
The framing around Australia's developed tunnelling sector versus bringing in "the best of the best" speaks to a pattern where national capacity is acknowledged but immediately positioned as needing external expertise for world-class outcomes. The ECI process, guided by figures like Tim Parker and Catherine King, functions as an imposed mechanism for validating that this needed external expertise translates into tangible engineering efficiency and value for money. The consideration of advanced manufacturing represents a parallel shift in paradigm—moving beyond physical construction to integrated systems delivery, which speaks to systemic shifts in how infrastructure projects are managed globally.
The core implication is the structuring of opportunity: by forcing competition over methodology rather than just price, the system attempts to resolve ambiguity surrounding novel technical challenges upfront. The resulting selection process will determine not only *who* builds the tunnels but *how* they define and mitigate the inherent uncertainties in the geology and complex station integration. What assumptions underpin the weighting given to innovation versus proven delivery methods in this competitive evaluation? What are the long-term structural consequences for Australian infrastructure development when these high-stakes decisions are made through iterative, collaborative discovery rather than top-down decree?
