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 soul 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 differently - with connection, conservation, and community at the heart of everything we do.
​
We keep things small, personal, and authentic. Most retreats run with just 6–8 guests, and we’ll never go over 15. You’ll never be lost in a crowd or herded around in a big tour group. Smaller numbers mean more support, safer in-water experiences, and more time in the water and proper time to connect with the ocean, the people around you, and yourself.
​
Our facilitators aren’t here for a free holiday - they’re ocean professionals who live and breathe this lifestyle. From freedivers and instructors to photographers and marine guides, everyone on our team genuinely understands and respects marine life. We pride ourselves on creating supportive, inclusive environments where every guest feels seen, encouraged, and part of the crew.
We also believe in fair, transparent pricing. No hidden USD conversions, no insanely inflated markups, and no unnecessary extras. What you see is what you get - high-quality experiences, locally guided, and ethically run.
​
Every retreat has its own energy. Some are all about chasing epic marine encounters, others focus on developing your freediving skills, and some are designed to help you unplug and reset. There’s no pressure, no strict schedules, just freedom, fun, and growth at your own pace.
​
We proudly partner with local operators and venues in every destination. It’s our way of supporting local communities, keeping tourism dollars where they matter, and ensuring every experience is grounded in real culture and knowledge. We also make sure everything we do is eco-friendly and sustainable - from reef-safe sunscreen and reusable gear setups to minimal-impact diving and ocean conservation education.
​
When you join a Deep Sensations retreat, you’re not just joining a trip, you’re becoming part of a community that values connection, conservation, and good vibes in and out of the water.
