Quick Contact


Ant Williams is a world-record freediver, mental fitness expert, and keynote speaker who brings his extraordinary experiences under extreme conditions to audiences worldwide. He has held his breath for over 8 minutes, dived to 100m on a single breath, and swum 182m under solid Arctic ice—pushing the limits of human endurance while demonstrating the power of mental resilience and focus.

Before becoming a professional adventurer, Ant was a sport psychologist, working with elite athletes including MotoGP riders, big-wave surfers, and rock climbers. Despite his expertise, he often felt like a fraud, teaching principles of performance and risk management from textbooks rather than lived experience. Driven by curiosity and a desire to test his own methods, Ant turned to high-risk sports, uncovering firsthand what it takes to master fear, take calculated risks, and perform at one’s peak under pressure.

Ant’s keynote presentations are a unique blend of gripping storytelling, applied psychology, and interactive exercises designed to help audiences enhance mental fitness, embrace challenges, and achieve exceptional results. In 2025, he was featured in an immersive film with Apple, further showcasing his ability to translate extreme experiences into actionable insights for personal and professional growth.

Renowned for his authenticity, charisma, and insight, Ant empowers organizations and individuals to navigate uncertainty, unlock potential, and thrive in high-stakes environments.

Ant was fantastic. Mindset really plays an integral part in our ability to achieve brilliant things. Believing in ourselves and increasing our confidence certainly goes a long way to help us become brilliant. Westpac
Ant was an inspiration for our sales team who were all very impressed with the interactive elements of his presentation and learnt a lot about how elite athletes motivate themselves to compete. Again Ant related this easily back to the environment that the sales team are in everyday. Adidas
Thanks for your involvement in our Dealer conference last weekend. The presentation including your amazing achievements in the world of freediving astounded both me and our Dealers - a refreshing break in the flow of the conference. The presentation worked particularly well in that we had all delegates up on their feet and involved in doing something physical. Aquanaut
Ant was excellent and extremely professional. His speech was well delivered, funny, interactive, motivational and had a message that fitted the theme of our conference. Our members really enjoyed how he interacted with them. We would have no hesitation recommending Ant on to any perspective clients. United Travel
Ant’s presentation was very positive and we were amazed by what the body was capable of enduring. The T – 1 model made people think about what they could do with perseverance and limited pain if they pushed through their own comfort zones. Inland Revenue Department
Ant was fantastic and our customers loved him. His passion for diving really shines through and his ability to relate the key skills from his sporting success to our customers was really great. The interactive nature of the presentation was also a big hit with everybody. We would definitely recommend Ant! Gentrack Pty Ltd
The highlight of the [senior leader] Residential was Ant Williams & Ben Roberts-Smith. Both were absolutely great keynote speakers. I'm still on a 'post-residential high' - People have said today how calm and serene I seem - must be the breathing techniques!! I learnt from Ant to control the mind chatter, you can push yourself further than you think Telstra
Your presentation at Macquarie yesterday was awesome I was absolutely enraptured as were my colleagues. You were able to bring us all on a journey with you, we felt your highs, lows, solitude and terror; it was amazing the way you did this. I found myself anxious before we did the holding the breath challenge and relieved once done. The way you seamlessly linked your rich experiences with our working environment and challenges was very clever, you left a very strong impression on me and on everyone else in the room Macquarie Bank
