The Commissioners

Mr Greg Hood 

Greg Hood was appointed to the role of Chief Commissioner and Chief Executive Officer of the Australian Transport Safety Bureau (ATSB) on 1 July 2016.

In his time as Chief Commissioner, Greg has overseen a number of significant transport safety investigations and report releases across the three modes of aviation, rail and maritime.  He has also successfully transitioned the ATSB into its new role as the single national rail safety investigator, bringing to a close a commitment to rail reform initiated by the Council of Australian Governments in 2009.

With more than 35 years of experience across a wide range of operational, training and management roles within the civil aviation industry, Greg has been well-positioned to drive an innovation agenda at the ATSB.  The ATSB’s evolution program has already seen enhancements to its world-leading practices, including streamlined operations, a multi-modal team approach to transport safety investigations and the introduction of remotely piloted aircraft to capture evidence following accidents and other safety occurrences.

Prior to his commencement with the ATSB, Greg held the role of Executive General Manager, Air Traffic Control with Airservices Australia.  In this position, he was responsible for the management of over 1,300 air traffic management staff, providing services for 11 per cent of the world’s total airspace for more than four million flights annually from 28 air traffic control towers and facilities.

Greg began his career as an air traffic controller in the Royal Australian Air Force in 1980, serving at locations throughout Australia and in the Middle East.  In 1990, he moved to the Civil Aviation Authority, a predecessor to what is now Airservices Australia.  Greg worked in many locations across the country, and was also involved in the training of new controllers at the University of Tasmania, Launceston.

In 2002, Greg was appointed to lead the management team in Melbourne, and then, in 2005, he led the team responsible for the provision of regional air traffic services, including the operation of regional control towers throughout Australia.  Greg has also been integrally involved in the implementation of major air traffic management and technology projects, such as the Australia Advanced Air Traffic System known as TAAATS, the evolution of safety management systems and the introduction of user-preferred routes and flex-tracks.

In 2007 Greg joined the Civil Aviation Safety Authority (CASA), where he held the positions of Group General Manager Personnel, Licensing, Education and Training, then Executive Manager Operations.  He returned to Airservices during 2013 to take on the role of General Manager Demand and Capacity Management and was appointed as the Executive General Manager of the Air Traffic Control Group later the same year.

Greg has served on the Business Advisory Council for World Vision, is a Fellow of the Royal Aeronautical Society, a Freeman in the Honourable Company of Air Pilots, a Life Member of the Qantas Founders Museum, and past President of Canberra Philharmonic Society. Until being appointed as ATSB’s Chief Commissioner, he was also a Board Member of Safeskies Australia and internationally, Vice-Chair of the steering committee for the Civil Air Navigation Services Organisation’s Operations Standing Committee.

He has a passion for the transport industry in general and transport safety in particular.  He is a glider and powered aircraft pilot.

For a number of years, Mr Prosser managed offshore supply vessel operations in Bass Strait prior to moving to Tasmania where he headed up the Polar Division of an international organisation managing the Antarctic and Marine Science Vessels for the Australian Antarctic Division and the CSIRO.
