Professor Sidney Dekker

Sidney Dekker (PhD Ohio State University, USA, 1996) is Professor in the School of Humanities, Languages and Social Science, and Director of the Safety Science Innovation Lab at Griffith University in Brisbane, Australia. Sidney has lived and worked in seven countries across four continents. He coined the terms ‘Safety Differently’ and ‘Restorative Just Culture’ in the 2010s, which have since turned into global movements for change. They encourage organisations to declutter their bureaucracy and enhance the capacities in people and processes that make things go well—and to offer compassion, restoration and learning when they don’t. His work has inspired generations of professionals and consultants globally. Many today will recognise Sidney’s ideas and concepts in for example ‘HOP,’ ‘Learning Teams,’ the ‘New View,’ and more.
An avid piano player and pilot who learned to fly at age 14, he has been flying the Boeing 737 for an airline on the side.
He is a trained mediator and Crisis Chaplain.
Sidney is prolific and bestselling author of, most recently: Safety Theatre; Ten Virtues of a Positive Safety Culture; Random Noise; Stop Blaming; Foundations of Safety Science; The Safety Anarchist; The End of Heaven; Just Culture; Safety Differently; The Field Guide to Understanding ‘Human Error’; Second Victim; Drift into Failure; Patient Safety; Compliance Capitalism; and Do Safety Differently.
He has co-directed the documentaries ‘Safety Differently,’ ‘Just Culture,’ ’The Complexity of Failure,’ and ‘Doing Safety Differently.’
His work has well over 21,000 citations and an h-index of 64.
Stanford has ranked Sidney among the world’s top 1% most influential scientists since Newton. More at sidneydekker.com
Angela Garvey

Angela Garvey is the Founder and Director of Navigating Aviation, a psychosocial safety and wellbeing consultancy dedicated to the aviation industry. With over 30 years of experience spanning aviation operations, safety management and regulatory roles, and as a commercial pilot herself, Angela brings a rare blend of industry insight and clinical expertise to her work. She is a registered counsellor specialising in supporting the aviation sector, is completing a Bachelor of Psychological Science, and is an accredited Mental Health First Aid Instructor.
Angela recently led a two-year federally funded initiative under the Department of Infrastructure’s Women in Aviation Industry Initiative, producing Australia’s first National Aviation Culture and Wellbeing Survey and delivering a national support program across multiple operational bases. She has engaged with more than 35 industry bodies, including CASA and the ATSB, and is a sought-after keynote speaker on psychosocial hazard legislation and Positive Duty obligations under the Sex Discrimination Act.
At PACDEFF, Angela will speak about the work conducted over the past two years and the profound impact that industry-specific support can have within aviation – an industry with a long-standing culture of keeping quiet and not speaking up, often driven by concerns about professional reputation, career consequences and medical licensing. Drawing on the findings and experiences from the national program, Angela will explore why understanding the unique culture and pressures of aviation is critical to creating psychologically safer workplaces where people feel able to seek support and speak up before harm occurs.
Angela’s contributions to the sector have been recognised with Australian Aviation Awards for Female Leader of the Year and Overall Industry Excellence.
