Dr Richard “Harry” Harris SC OAM is an Adelaide based anaesthetist who has experience in pre-hospital and retrieval, diving, expedition and wilderness medicine. Diving for forty years, he has focussed on cave exploration since the year 2000. He was requested to assist with the rescue of 12 boys and their coach from the flooded Tham Luang cave in northern Thailand in July 2018. Along with his dive partner Craig Challen, he was closely involved with the extraction of the boys from over 2.5km underground using an unconventional and unprecedented technique involving general anaesthesia. Harry’s talk about the rescue illuminates the desperate nature of the operation, the importance of close teamwork and the courage shown around the difficult decisions that were made by the team. It is guaranteed the audience will be on the edge of their seats.
