MMRA is an Administrative Office established in relation to the Department of Economic Development, Jobs, Transport and Resources.

MMRA is responsible for all aspects of the project including planning and development of a project reference design, site investigations, stakeholder engagement, planning approvals and procurement, through to construction delivery and project commissioning.

Metro Tunnel is one of Australia's largest ever public transport infrastructure projects and Victoria's most complex rail upgrade in decades.
