The search is on for businesses, investors and construction experts with the know-how and experience to help deliver Melbourne Airport Rail Link.

Registrations of Interest (ROI) are now open for providers to help deliver the project.

The ROI process, led by Rail Projects Victoria, will help government assess which organisations have the experience and capability to help bring the project to fruition, as well as gauging potential interest from private sector investors and operators.

The search includes designers, engineers, rail systems providers, rolling stock providers, investors, financiers, developers and other rail infrastructure providers.

The full Business Case is currently being developed in partnership with the Commonwealth Government.

Further information about registrations of interest is available on the Rail Projects Victoria website.
