About Gary
Gary Liddle was a deeply respected transport industry leader, volunteer Trustee of the iRAP charity for 9 years and Chair of the iRAP Board from 2017-2022. Prior to his passing with MND in 2023, his leadership and wisdom helped grow the charity’s impact to the point where more than 400,000 deaths and injuries had been saved by partners worldwide, 172 countries had been supported with iRAP resources and more than US$95 billion of infrastructure investment was made safer.
Gary served the transport industry for more than 40 years. In that time, as well as supporting iRAP, he occupied senior leadership positions in the Australian road sector, including as Chief Executive of VicRoads, Deputy Secretary of the Department of Transport, Planning and Local Infrastructure (Vic), Chair of ARRB, Chair of Austroads and Chair of iMOVE, Board Member of Roads Australia and governing roles in both PIARC and REAAA.
In 2017, Gary was made an Officer in the Order of Australia (AO) for “distinguished service to public administration in the Victorian transport sector through leadership in policy direction, infrastructure development, road safety and regulatory reform.” He was a strong and steadfast leader, generous and supportive mentor and committed advocate for road safety.
