Deep cave diving is arguably the last true frontier of exploration on Earth—a realm where “extreme” is an understatement.
Deep within the rugged wilderness of New Zealand’s South Island, a dedicated brotherhood of elite divers, led by Dr Richard “Harry” Harris, has targeted a subterranean system that may hold the title for the deepest cave ever explored. The expedition is as daring as it is controversial; to withstand the extreme depths, the team intends to breathe a hydrogen-based gas mixture. While this chemical solution allows them to push physiological boundaries, its highly volatile and explosive properties introduce a terrifying new layer of risk to an already lethal environment.
An Australian anaesthetist and elite cave diver, Richard “Harry” Harris, SC, OAM, PBh (GCT), has held the position of Lieutenant Governor of South Australia since 2024. While he gained international fame for his heroic contributions to the 2018 Tham Luang cave rescue in Thailand, Harris is also a trailblazer in technical diving. He made history as the first person to utilize hydrogen as a rebreather diluent gas and has successfully descended to depths of 245 meters. In recognition of their bravery and service, Harris and his longtime diving partner, Craig Challen, were jointly named the 2019 Australians of the Year.
Beyond exploration, Harris has been called upon for his expertise in somber circumstances. In 2011, at the request of the South Australian Police, he performed the harrowing task of recovering the body of his close friend and fellow diver, Agnes Milowka, from a cave system near Tantanoola. Today, he continues to contribute to the global diving community as the Australian regional coordinator for the International Underwater Cave Rescue and Recovery organization.
