Mark is a recently retired dentist who has delicately balanced two vocations: the demanding practice of dentistry and his exploration and documentation of the ocean world. He first ventured into the ocean under-world in 1975, during his university years and took his first photographs underwater in 1978. He won Australian Geographic’s “Best Photographer” award in 2022.
Mark-the author of the book ‘Ocean of self’- will talk about some of his shipwreck and cave diving adventures and some marine wildlife encounters. His book examines the nature of consciousness using the ocean as a metaphor.
In 1997 and 1998 Mark led an Australian contingent on two expeditions to Turkey to examine the alleged discovery of the Australian WW1 Submarine AE2. He will also discuss how these experiences have shaped his world view and his understanding of the connectivity between all things.
