Our internships are tailored to give interns all the skills needed to become a divemaster, whether your goal is to pursue an adventurous career underwater or simply to take a break in paradise while advancing your skills and knowledge as a diver.
After completing internship training, our divemasters are able to guide certified divers on fun dives and assist Instructors throughout courses.

We’re a tribe full of island addicts and of course, ocean lovers. Do your divemaster internship and spend a few weeks (or even months) with us living in a place where time stops… no cars, no motorcycles, no fuss… just you and your own small piece of paradise.
During the divemaster internship, our interns experience another way of life where all you need is your swimsuit, sunglasses and flip flops!
You’ll be surrounded by crystal blue water and sunshine all year round, with green turtles at your doorstep and clownfish as co-workers.
Whether you want to work in a far away and exotic destination after your divemaster internship or just take some time off, the adventure of a lifetime awaits you!
