Why Freediving?
Learning to freedive opens up a whole new world beneath the surface. It challenges you physically and mentally, helps you develop greater awareness of your breath and body, and introduces you to the incredible marine life that call our oceans home.
Beyond the water, the skills you develop through freediving – from breath awareness to staying calm under pressure – can influence how you approach everyday life. It's an opportunity to challenge yourself, build confidence and experience the ocean in an entirely different way.

Meet Rosie
I'm Rosie, owner and lead instructor at Eunoia Freediving, which I established in 2021 to share a world that has had such a positive impact on my own life, and that I hope others can experience too.
I discovered freediving after moving from London to Sydney in 2018, and since then it has become a huge part of my life. After almost a decade working as a high school teacher, I was feeling increasingly burnt out and found in freediving a place of calm amongst the chaos – a way to quiet the noise of everyday life, and to be completely present.
As a freediving instructor, I love sharing that experience with others, helping people build confidence in the water and discover the many ways freediving can enrich their lives.

Reviews From Our Freedivers
"The 2 day beginner freedive course was amazing! Rosie is a brilliant instructor, patient, knowledgeable and full of tips throughout the course. Day one pool session was made easy, safe and very comfortable. Day two, I was very nervous at the start but the guidance and support from Rosie had my confidence up in no time and having fun free diving. Overall, I’d highly recommend learning through Eunoia Freediving, it’s a great experience, I absolutely loved it and I'm looking forward to using the skills I've learnt to improve my underwater photography! Thanks Rosie and team!"
Kyle J: Beginner Freediving Course
"I learned to freedive about six months ago and, despite loving freediving itself, I unfortunately had a less-than-favourable experience with another instructor. Since meeting Rosie, Remy, and the Eunoia team, that experience has been completely healed. Their instruction is exceptional and delivered within a calm, clear, patient, nurturing, and genuinely supportive environment. Safety is clearly their top priority, which allows me to fully relax and focus on the joy of freediving. I’ve done both pool sessions and a line session with Eunoia, and I’m amazed at how quickly I’m hitting personal bests under such skilled and encouraging guidance. I can’t wait to continue training, join trips, and spend more time with Rosie, Remy, and the incredible freediving family they’ve cultivated."
Arany N: Pool & Depth Training
“I did the 3 hour introduction to free diving course with Rosie and had the best time! Rosie made me feel calm in the water and she guided me professionally and made the whole experience really fun. I managed to dive deeper than I thought I would be able to and I've honestly never felt more badass in my life. Now I'm thinking about doing the SSI beginner course because I actually liked it so much. Thank you so much Rosie - you're the best!”
