Infrastructure Australia is an independent statutory body providing independent research and advice to all levels of government and industry on projects and reforms relating to investment in Australian infrastructure.

In 2014, the Infrastructure Australia Act 2008 was amended to give Infrastructure Australia new powers, and to create an independent board with the right to appoint its own Chief Executive Officer.

Mark Birrell retired from his role as Chairman of Infrastructure Australia in August 2017, and Julieanne Alroe was appointed to the position in September 2017.

Alroe and the 12 members brought experience from business, academia, the public and private sectors.

[3] The authority is part of the Department of Infrastructure, Transport, Regional Development, Communications and the Arts, and Catherine King, has been the responsible minister since May 2022.
