Ant Williams is a world-record freediver capable of holding his breath for more than eight minutes and diving to depths of 100 metres on a single breath, but the achievement that best captures his story is a 182-metre swim beneath solid ice in an unforgiving Arctic landscape, a feat so remarkable it was captured for Apple’s Adventure series as Ice Dive, filmed in immersive 8K for Apple Vision Pro and watched by audiences worldwide. He does not simply talk about risk-taking and mental toughness on stage, he has genuinely lived it, at depths and in conditions few people could imagine surviving.

What makes Ant’s story unusual is where he started. Long before he became an extreme athlete, he worked as a sport psychologist coaching elite performers including MotoGP riders, big wave surfers and rock climbers, teaching them mental toughness techniques drawn entirely from textbooks rather than lived experience. Over time that gap began to feel increasingly uncomfortable, so Ant set out to test his own theories by taking up one of the most dangerous sports imaginable, using freediving to discover firsthand whether risk-taking and resilience could genuinely be learned rather than simply taught in a classroom or a coaching manual.

Since then Ant has become the case study he once only theorised about, and his 2025 feature in Apple’s immersive Adventure series brought that story to a global audience in a completely new format. On stage, he combines gripping storytelling with applied psychology and interactive exercises designed to help audiences perform at their peak when the stakes are genuinely high. As founder of Modus Leadership, Ant translates the mental discipline required to hold his breath at extreme depth into practical, transferable lessons on mental resilience and performance under pressure for corporate and event audiences everywhere. Based in Bells Beach, Victoria, he is available for international keynote bookings across every industry.

Teamwork at the Edge(60mins)

What happens when a high-performing team, built for success, completely unravels under pressure?

Corporate teams may not face the Arctic cold, but they do face relentless change, high stakes, and the challenge of leading through uncertainty.

In 2019, Ant Williams set out to break an extreme sport world record — becoming the deepest man under ice yet within 24 hours of arriving in the Arctic Circle, his elite dive team fell apart.

Misalignment, poor communication, and a lack of trust turned a world-class operation into chaos.

Through vivid storytelling and an immersive problem-solving challenge, attendees will step into the shoes of his dive team, identifying critical decisions that could have turned the team around before disaster struck.

  • The cost of avoiding tough conversations
