David Knoff is an Antarctic Expedition Leader, Author, and leadership expert who specialises in remote leadership, hostile environment diplomacy, and resilience. David's international career has taken him across the globe with experiences as an officer in the Australian Army, diplomatic postings in Pakistan and Iraq, and most recently with the Australian Antarctic Program. In 2019, David was given a leadership challenge unlike no other in modern history, as the Station Leader at Davis Station, Antarctica, he was leading a team of just 24 through the isolation of an Antarctic winter when the COVID-19 Pandemic broke out. The impact of the pandemic on Antarctic operations saw David's team without a ride home as planned and facing one of the longest periods of isolation in modern Antarctic History. David's book, '537 Days of Winter: Resilience, Endurance and Humanity while stranded in Antarctica during the Pandemic' tells the story of what it was like to lead a team through unprecedented uncertainty and how to find resilience in the most extreme environments. Combining his experiences from warzones and his six different Antarctic expeditions, David now works as a professional speaker to help others learn from his experiences in order to further their own knowledge of leadership in extreme situations. David's unique story also helps organisations and individuals understand the importance of environmental awareness and works with schools and corporations to better understand humanity's impact on climate and the planets most remote wilderness in Antarctica.
