Prospective pipeline

Greenfield (construction) or brownfield (government asset divestment) projects needed or likely to occur within the next five years, but is not formally proposed by a state, territory or major local government.

Credibly proposed

The project or divestment is supported by a state, territory or major local government, is subject to studies or other processes (such as pre-feasibility or scoping studies or business case development), and is likely to proceed to formal announcement.   


The project has a firm commitment and timeline from a state, territory or major local government, but has not yet entered the market.

Under procurement

The project or transaction is under procurement (such as a call for Expressions of Interest, requests for tender, or another offer to the market).

Preferred bidder announced

A preferred bidder has been selected and is in exclusive negotiations.

Recently closed

Projects that have progressed to contractual close remain on ANZIP for 12 months.

ANZIP is focused only on major infrastructure activity, above the following thresholds:


Construction projects: > AUD$300m

Investable greenfield & brownfield: > AUD$100m

New Zealand

All greenfield and brownfield projects and divestments: > NZD $100 million

STATUS: Credibly proposed
TYPE: Greenfield

The Beaches Link project is a proposed tunnel linking the Northern Beaches to the Warringah Freeway and south across the harbour (with links to Western Harbour Tunnel and Westconnex).

The 2016-17 NSW Budget allocated $17.6 million for planning for the Western Harbour Tunnel and Beaches Link.

The option for a Beaches Link (previously referred to as the Northern Beaches Motorway Tunnel) was explored as part of the Northern Beaches Transport Action Plan. $5 million from Restart NSW was committed for strategic and feasibility studies, which evaluated a number of potential routes,including a southern route under Mosman as well as a northern route under Middle Harbour and Northbridge

In March 2017 the NSW Government announced the preferred corridor - the northern route - and the start of the market sounding process for both the Beaches Link tunnel and the Western Harbour Tunnel, and an upgrade to the Warringah Freeway. These three projects are likely to be awarded as separate contracts, with the configuration and scale of the contracts yet to be determined.

Market sounding is likely to test the private sector’s appetite for revenue risk and tolling, and investigate if a lease of existing north south harbour crossings could minimise the financial burden on the State. It is also likely the packages of work will be tendered under a traditional Public Private Partnership model with private finance.

The NSW Government has also committed $77 million towards geotechnical investigations for the projects which started in April 2017 and involve the drilling of 235 boreholes across the combined route of the projects. Coffey and AECOM are conducting the investigations.

The 2017-18 NSW Budget allocated $103 million towards planning works for Western Harbour Tunnel and Beaches Link projects.

In November 2017, a State Significant Infrastructure (SSI) application was lodged to identify topics that must be assessed in any future Environmental Impact Statement (EIS). EIS documents are expected to be submitted in the second half of 2018.

The project is expected to take around five to six years to build, and a more detailed construction programme will be included in the EIS. This would include:

- detailed project design;
- final project costings;
- funding strategy including tolling options;
- private sector involvement; and
- construction timeline.
