Seeing isn’t Believing 

TEDx SPEAKER & MENTALIST

“How much of your reality can you really trust?”

Andy Nunn’s Seeing Isn’t Believing reveals how easily the mind can be influenced and how awareness changes everything. Blending psychology, humour, and live mentalism, Andy takes audiences inside the illusions shaping trust, perception, and decision-making.

This isn’t a talk; it’s an experience. Through interactive demonstrations and storytelling, Andy shows how small shifts in perspective can transform how we lead, sell, and communicate.

Delivered on stages across Australia, including TEDx Sydney, Seeing Isn’t Believing challenges audiences to question what they see and rethink how they think.

Logos of companies Andy Nunn Keynote Speaker has performed and spoken for, including Google, Amazon, Canva, EY, Qantas, American Express, Ralph Lauren, Tiffany & Co., Tommy Hilfiger, Stan, Cartier and Channel 7.
