The Deep Sensations Freediving Community Achievements
Not Just Freediving Courses
We’re here to share our love of the ocean, conservation, and the transformative world of freediving with both new and experienced divers.
Our founder, Curtis Tredway, is one of Australia’s deepest freedivers and has served as a Safety Diver for World and National Record attempts at the CMAS Freediving World Cup in the Philippines. With nearly a decade of experience across diving and ocean sports as a Divemaster, surf photographer, spearfisher, surfer, and underwater photographer - he brings passion, safety, and expertise to every course.
Curtis is also a huge advocate for mental health, ocean confidence, and marine conservation. Freediving helped him through his most challenging years, and now he’s made it his mission to create safe, supportive spaces where others can grow, reconnect with nature, and help protect the ocean that gives us so much.

The Deep Sensations Freediving Retreat Difference
At Deep Sensations, our retreats are built a little differently. Connection, conservation, and community sit at the centre of everything we do.
We keep things small, personal, and genuine. Most retreats run with just 6–8 guests, and we never go beyond 15. That means you’re never lost in a crowd or shuffled through a busy tour schedule. Smaller groups allow for more support, safer in-water experiences, and more time actually enjoying the ocean, while connecting with the people around you and the environment you’re exploring.
Our facilitators aren’t there for a free holiday. They’re ocean professionals who genuinely live this lifestyle. From freediving instructors and safety divers to photographers and marine guides, our team understands the ocean and treats marine life with respect. We focus on creating relaxed, supportive environments where every guest feels welcome, encouraged, and part of the crew.
We also believe in fair and transparent pricing. No hidden USD conversions, no inflated mark-ups, and no unnecessary extras. What you see is what you get, thoughtfully designed experiences, guided by people who care about the ocean and the people sharing it.
Each retreat has its own personality. Some are centred around incredible marine encounters, others focus on developing your freediving skills, and some are simply about slowing down, reconnecting with nature, and resetting. There’s no pressure and no rigid schedules, just space to explore, learn, and enjoy the experience at your own pace.
Wherever we go, we work closely with local operators and venues. Supporting local communities is important to us, and it helps ensure every experience is grounded in real local knowledge and culture. We also do our best to minimise our environmental impact, encouraging reef-safe practices, low-impact diving, and ocean awareness throughout our trips.
When you join a Deep Sensations retreat, you’re not just booking a trip. You’re joining a community of people who share a genuine appreciation for the ocean, good company, and unforgettable experiences in and out of the water.
