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 highly recommend learning through Eunoia freediving, its a great experience, absolutely loved it and I'm looking forward to using the skills I've learnt to improve my underwater photography! Thanks Rosie and team!"

  • "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."

  • "I loved the beginners course with Eunoia Freediving - Rosie was incredibly patient, knowledgable and overall a great instructor to dive with! The pool session on the first day followed by the open water session the next - was a great intro to for newbies like myself. We felt very comfortable and relaxed despite it being our first time swimming in open water, but Rosie was always there to give us tips on equalising, breathing techniques and more. Would highly recommend for those looking for a fun yet challenging weekend"

  • "I loved the experience of freediving for the first time. Rosie is amazing and the technique she teaches really helps you to get more relaxed and hold the breath for longer periods of time. I thought it would be a tough and stressful experience but it was quite the opposite, it was a meditation. Rosie is also very kind, calm and patient and we could connect really well, which I think was fundamental to learn the lessons and for getting better every step of the way. Definitely would recommend for everyone who loves the sea, diving or just wants to get less anxious and relaxed. I’m 100% coming back for the line training sessions soon"

  • "Rosie is an incredible freediving instructor! Rosie and her team took me from an absolute novice beginner, being afraid of putting on a snorkel to helping me learn how to breathe, slow down my heart rate and equalise underwater. I can now freedive with the invaluable skills she has taught me. She also takes amazing underwater photos. I didn’t know I could do this nor that I could be the subject of such incredible pictures! I highly recommend Rosie and Eunoia Freediving for a safe, reliable and fun freediving experience!"

    Belinda J

  • "Rosie is an amazing instructor, very friendly and genuine. I really appreciated the small class size. It helped me feel safe and comfortable as this was my first free diving experience. She gave great instruction and feedback. So happy to have been submerged into the free diving world with such a good company! Can't wait to get out there again!"

    Hannah G

  • "The Komodo trip with Rosie was one of the best trips we have ever done! All the instructors were so knowledgeable and we got so much one on one time to do our free diving course. The boat and its crew were amazing and the food was next level. I will be recommending this trip to everyone in the future!"

    Hannah S

  • "Would highly recommend Eunoia Freediving. Big thanks to Rosie for ensuring our free diving course went ahead. Our instructor Bryan was amazing! All four of us thoroughly enjoyed the 2 day course. As well as learning how to free dive we also felt that the techniques learnt have massively improved our snorkelling experiences too! We can’t thank Bryan enough for being patience, super supportive and an all round brilliant teacher. Bryan adapted some techniques to suit our capabilities. We look forward to line training with Eunoia Freediving when we are back in Sydney."

  • “Had a great time with the level 1 course! Rosie created a safe and supportive environment and I was nowhere near as anxious as I expected to be. Finished the weekend amazed at what I was able to achieve. Thank you!”

    Marlane C

  • "I can’t recommend Eunoia enough! I've done multiple line sessions with Rosie and been really impressed with her experience and ability to pick up on subtle techniques that have made a huge difference in my diving ability and confidence. She is super attentive and fun to dive with, always leave our sessions feeling amazing. I have also done two underwater photography sessions with her and have the best photos that look great on tinder hahaha"

Who are we?

I’m Rosie - lead instructor and owner of Eunoia Freediving.

I discovered freediving when I moved from London to Sydney in 2018, and since then it has become my world. After working as a high school teacher for almost a decade, my life was full of stress and anxiety; it was discovering freediving that enabled me to find a place of calm amongst the chaos - a place to quiet the noise of the everyday.

Freediving introduced me to mindfulness techniques that not only enable me to stay underwater longer, but help me to cope with the stresses of the everyday.

Qualifications: SS1 Level 2 Freediving Instructor, Emergency First Aid Responder, CPR & Oxygen Provider
