Cas is one of Australia’s 50 Greatest Explorers

Crossing the Ditch: In late 2007, Cas and his best mate, Jonesy, made history by completing the longest unsupported transoceanic double kayak expedition—a Guinness World Record. Over 62 days, they kayaked 3318km across treacherous seas, facing dwindling supplies, technical issues, 14 days trapped in a whirlpool, and two close encounters with sharks. After this endeavour, Cas spent a lot of time reflecting on his learnings, reinforcing his belief that every lesson can be applied to any difficult situation and to anyone striving to achieve something extraordinary.

Polar Expedition: Following their Tasman Conquest success, they set out for another extraordinary journey. On the 26th of January 2012, they became the first to walk from the edge of Antarctica to the South Pole and back unassisted and unsupported. In 100 years of polar exploration, no one had ever successfully achieved this feat. This historic expedition showcased their growth mindset, teamwork, and determination to turn audacious goals into reality.
