Michael Hopkins

Michael Hopkins brings significant expertise in transport reform to the NTC. As a senior executive in Victoria's Department of Transport, Michael delivered future-focused policy reforms, network strategy and planning, as well as stronger governance to improve the way transport works. His focus is on delivering reforms that improve the lives of Australians, whether through shorter, faster journeys, cheaper goods because the freight network is more efficient or through safer roads and rail travel. 

As a consultant, Michael provided expert evidence-based advice to industry and local, state and national governments on responding to the contemporary challenges faced by a transport sector in transition.

Michael knows the NTC. He has previously been an Executive Leader at the NTC driving the organisation’s work program, the delivery of reforms and the Commission’s relationship with its partner governments.
