Two world records and a former Deloitte management consultant, James “Cas” Castrission turns what the Tasman Sea and the South Pole taught him into practical tools for teachers and education staff who keep the school day running, look after each other, and hold it all together for the whole school year.
EDUCATION CLIENTS:










THREE WAYS TO BRING JAMES TO YOUR SCHOOL COMMUNITY
IMMERSIVE & CONFERENCE KEYNOTE
Start with Immersive: Uncharted Ice or Uncharted Waters, MAG’s signature expedition simulation, where your people make high-stakes calls together. Or book James’ keynote, tailored to your conference theme, where the Tasman crossing and the South Pole become a practical way into resilience, change, and high-performing teams. Both work for a full room of principals and teachers, or a whole-of-system gathering.
LEADERSHIP WORKSHOP
A hands-on workshop for your leadership team, drawn from Cas’ workshop program and shaped around your school. Your team works through real challenges, from leading through change to keeping staff together when the pressure builds, and walks out with tools and an action plan they can use from Monday. Built for leadership PD, pupil-free days, and executive team planning days.
VIRTUAL KEYNOTE
The keynote delivered live to screen. Ideal for regional and remote schools, diocese-wide staff briefings, or when the travel budget is tight. Three production levels, starting with a complimentary Home Delivery session.

THE CHALLENGES SCHOOL LEADERS AND TEACHERS ARE FACING RIGHT NOW
How Cas helps principals, assistant principals, teachers, and the associations that bring them together.
WE DIDN’T JUST GIVE A KEYNOTE. WE RAN THE WHOLE EXPERIENCE.
Assistant principals from across Western Australia spent six hours with James on leading with purpose. Instead of a one-hour talk, the association got Uncharted Ice, MAG’s immersive expedition experience, plus a structured Grit Scale self-assessment. Every leader walked out with a measure of their own resilience and a way to use it back at school.
“He was able to link that back to school context, to assistant principals, and our roles at school… It was a Friday afternoon, but the level of engagement was still outstanding, and you could hear a pin drop in the room.”Geoff Clarke, Vice President, Catholic Assistant Principals’ Association of Western Australia
HEAR FROM CLIENT EXPERIENCE
“Cas has led two amazing sessions for One Ventures over the last couple of years, using his real-world experiences to help show how a team can become a high-performing team.”
HOW IT WORKS
FAQ
The keynote is for a large audience, such as a conference, staff day, or association event. It shares James’s expedition stories and turns them into lessons on grit, resilience, and leading under pressure. The Leadership Workshop is a hands-on session for a smaller group, usually an executive or leadership team. Your team works through real challenges and leaves with tools and an action plan. Many schools book the keynote for all staff and the workshop for their leadership team.
James draws on two world-record expeditions, crossing the Tasman Sea by kayak and walking to the South Pole and back. He uses them to show what keeps people going when the pressure builds. For school leaders, that means grit and resilience, decision-making under pressure, and how high-performing teams stay together through a demanding year. Each session includes practical tools, such as the Grit Scale self-assessment, so staff take away more than a story.
It’s built for the people who run schools day to day: principals, assistant principals, deputy principals, and school leadership teams. It also suits principals’ and assistant principals’ associations, Catholic and independent school networks, and whole-staff days. James has spoken to state associations such as the Catholic Assistant Principals’ Association of Western Australia, as well as individual schools across Australia.
Yes. Every session is shaped around your theme, your audience, and what you want people to do differently afterwards. Before the event, James talks with your organising team about the challenges your leaders and staff are facing, then builds his stories and tools around them.
Yes. Pupil-free days, staff PD days, and start-of-term planning days are some of the most popular times to book. Many schools pair a keynote for all staff with a Leadership Workshop for the executive team on the same day.
No. The expeditions are the way in, not the point. Sessions are built around practical tools that leaders can use the following week: the Grit Scale self-assessment, making decisions under pressure, and how teams stay together when things get hard.
Yes. James presents in person across Australia, and virtually for regional and remote schools, diocese-wide briefings, or dispersed networks. Virtual delivery comes in three production levels, starting with a complimentary Home Delivery option.
Associations usually confirm conference speakers 6–12 months ahead, so now is a good time to talk about 2027 conferences. For pupil-free days and workshops, a term’s notice is ideal, but get in touch even if your date is closer. James’ availability changes quickly.
