Had a great time freediving today with the OceanSense team. Everyone was courteous and professional and did an excellent job of managing varying competency levels. I was impressed with the way they balanced covering important safety items while keeping things lighthearted and fun. I also enjoyed learning about the history of the sites we dove. I’d recommend them to anyone looking to get their freediving certifications or, if already qualified, as a great way to get some depth practice in. Definitely will book again.

I couldn’t recommend OceanSense enough!
I recently completed my freediving course with OceanSense & honestly had the most amazing experience. The course taught me so much about freediving, breathwork, equalisation, safety & building confidence in the water. I feel like I’ve come away with a much better understanding of my body, the ocean & how to freedive safely.
A huge thank you to Renee, Maria & Gonzalo for being such incredible instructors. You were all so patient, encouraging & supportive throughout the whole course, & made me feel comfortable every step of the way. I really appreciated how much time you took to explain things, answer all my questions & help me work through anything I found challenging.
You can genuinely tell how passionate the whole OceanSense team is about freediving & the ocean, & that made the experience even more special.
I’m leaving the course feeling so much more confident in the water & absolutely hooked on freediving! I’m so grateful I got to learn from such an amazing team & I can’t wait to keep progressing.
Thank you OceanSense, Renee, Maria & Gonzalo!

I Recently returned from a freediving retreat in Amed with OceanSense completing my Level 1. What a fantastic week, and an even better group of people! Loved every second of it. Jenna, Gonzalo and Renee were incredible instructors, calm, kind and patient. Between them they have so much knowledge and have an amazing set of skills. Highly recommend whatever level you are diving at, to check out OceanSense. This is just the start, I will be back :) Thanks Guys

I joined one of the Oceansense retreats in Bali. It was really well run, super professional and fun! Great instructors who were really encouraging and patient, and they also held some great masterclasses in lung stretching, relaxation, form and techniques. We had a good variety of organised line diving sessions, pool sessions and a fun trip in the middle. Sadly I got sick halfway through the retreat and it stopped me from finishing my course but they have the option to finish your course with them within a year which is great, it really took the pressure off. Highly recommend!!

It’s honestly hard to put into words how incredible the Amed Retreat with OceanSense was.
Their passion for what they do is infectious, and the huge effort they put into making the entire experience possible does not go unnoticed.
This retreat was the perfect mix of fun, adventure, and being pushed outside my comfort zone!
What truly made this experience so special was how supported and encouraged I felt every step of the way. The OceanSense team created such a genuine, welcoming environment where everyone was celebrated, no matter their freediving experience or confidence level.
I left incredibly grateful for the friendships and connections I made along the way. It’s an experience that will stay with me for a very long time.

I’ve just come back from my second Amed retreat with the OceanSense fam and I once again loved every minute of it! The instructors Jenna, Matt and Patrick are incredibly attentive and have an amazing skillset to share and learn from. They cater to all levels of diving and do everything in their power to ensure you have the best time along your diving progression journey. Thank you for helping me live my best mermaid life, for creating a friendly and supportive environment and for the amazing memories created along the way! If you’re new to Freediving or are wanting to learn new skills and reach new PB’s – OceanSense are the crew for you :) Thanks so much Jenna, Matt and Patrick!

Fantastic experience getting our Wave 1 with OceanSense! The entire team is so helpful and supportive. We did our pool day in Mooloolaba with Matt, and eventually our ocean day with Gonzalo, Carla, and Renee in the Gold Coast. The coaches really listen to what you need, and make everything feel very relaxed with no pressure to perform, which was really important to us.

A massive thank you to Gonzalo and Rene who helped me through my level 1 freediving course this weekend. What a great way to start the new year. Its going to be hard to find a more knowledgeable crew than this.
