Jonathan Sunnex

In 2011, Jonathan made a decision to commit his life to breath-hold diving. Within the year he was achieving depths greater than 70 meters, and soon after, he had broken the magical 100-meter barrier in CWT. He was the winner of the prestigious Triple Depth and Deep Dahab competitions in 2011, and in 2012 and 2013 (only his second and third years of freediving), he achieved top 5 world rankings in both FIM and CWT. Jonathan has represented New Zealand at the 2011 and 2013 Depth World championships, and in 2013 was the winner of the bronze medal for men’s FIM.
Jonathan is a world-renowned safety diver. He was a member of the Vertical Blue Safety Team in 2012, and in 2014 he returned as Chief of Safety and Event Manager for the competition referred to as “The Wimbledon of freediving” by The New York Times. His team of expert safety divers raised the bar and brought a new level of professionalism to safety at high-level freediving events. Since then, he has featured prominently on the competition circuit as an organiser and chief of safety. Jonathan assumed the role of AIDA Safety Officer in 2017, and together with an expert panel, he strives to improve the safety of freediving for all.
As a coach and instructor, Jonathan has helped athletes achieve five world records, more than 70 national and continental records, world number one rankings, and world championship medals. He is an AIDA and PADI Instructor trainer, SSI Master Instructor, and EFR instructor.
