Diving and marine conservation in Thailand

Help conserve the world’s depleting coral reefs as a marine conservation volunteer in Thailand. Immerse yourself in the underwater world completing daily dives off the stunning Thai island of Koh Phangan, all whilst helping with an important research and conservation project.

Most of the world’s coral reefs are under threat – and, without them, fish would eventually cease to exist. Play an active part in the efforts being made to halt this shocking decline, combining your passion for diving, conservation and travelling.

The Basics:

You can take part in this programme for 2, 4, 6 or 8 weeks throughout the year, with the exception of mid-December to mid-January.

2 weeks costs £1255 for PADI qualified divers; each additional fortnight costs £400. If you are not a qualified diver you can take the PADI Open Water course during your stay for an extra £350.

Whilst late-availability is possible, we would advise booking as soon as possible to guarantee your ideal dates.


Arrival day is a Monday. Arrival dates can be seen here. You are asked to arrive before 17.00 at Koh Samui airport for your transfer to the project on the Monday of your arrival.

  • Receive expert diving instruction and come away ready to dive in other places all over the world.
  • Test your skills in underwater photography and videography – not only does it help research, but it also provides a fantastic souvenir.

  • Make the most of life on the exciting island of Koh Phangan, which boasts gorgeous beaches, excellent hiking, great diving and a lively social life.

Enjoy daily dives and hands-on conservation volunteering

Experience life under the sea every day, helping to promote the survival of coral reefs and the many fish that need them to survive.

You’ll be working with a marine research organisation performing daily dives to help understand the local ecosystem, working to develop and implement reef conservation. See for yourself how reefs degrade from physical damage, overfishing, climate change and contamination – and find out from the experts about the work they are doing to reverse this. You’ll be spending plenty of time with them, learning all about marine conservation and the complexities of underwater life. Not only will you be diving in Thailand, one of the world’s favourite diving destinations, you will be making a valuable contribution to the future of marine conservation in Thailand.

All this takes place in the very friendly fishing village of Chalok Lum on the north western side of Koh Phangan – one of the most beautiful islands in the area.

What will I be doing?

On arrival you will be given a thorough induction course on diving and the organisation’s research methods.  For those who have yet to experience diving, you can take a 4-day PADI course which will be an exciting introduction to the project.

Each day you will go out to sea to visit the coral reefs just off the coast, diving in various stunning locations. This is an extremely hands-on project where each day you help towards the survival of the world under the sea. As an important member of the team, you will help with a wide range of projects such as:

  • Taking samples and measurements of the coral mass
  • Marvelling at the different species of fish as you come up close to them, count them and observe their behaviour.
  • Taking photographs of the coral and fish to help record any changes that occur.
  • Helping to gather data contributing to governmental surveys and research projects
  • Investigating how much live coral there is and the effects of coral bleaching
  • Completing fish surveys to know which fishes are living in this area
  • Growing “nubbins”, small coral fragments, in aquariums and planting them in the reef. This is a vital step to continue the survival of coral for many generations to come.
  • Measuring water temperature
  • Coral reef clean up programs- helping to remove fishing lines and other debris carefully from the reefs

Novices staying for two to four weeks will have the opportunity to become competent divers with an appreciation of the outstanding sights in the underwater world.  What better reason to join Oyster’s conservation diving project in Thailand, gain a diving qualification and use it to help the survival of the beautiful life forms you will see.

Whether you are looking to do a scuba diving gap year, are taking a career break or are simply looking for volunteer holidays abroad, becoming a marine conservation volunteer is a great opportunity to put into practice the diving skills that you learn.

Marine Conservation Internship opportunities

We are currently looking for interns to join this project for durations of 4, 6 or 8 weeks. Interns need to have studied or be studying in a relevant subject field (for example marine biology, biology, oceanography etc) and be passionate about marine conservation. If you would be interested in immersing yourself in research, diving, underwater photography and conservation work experience overseas, contact Anne on anne@oysterworldwide.com to find out more. You can see more information here. You do not need to have previous diving experience, as we can train you on the project.

Accommodation and Food

You will be living in the friendly community of Chalok Lum on the island of Koh Phangan. You will stay in comfortable accommodation on site at the research centre. The research team also live there, and it is a fun and relaxed environment which you will soon be calling home. It is located right in the heart of the village, so you will soon be recognising your neighbours and returning their smiles.  It’s a wonderful opportunity to interact with incredibly warm local people and share their way of life.

You will be sharing a room with at least one other person. Rooms are comfortable yet basic, with mosquito nets and a fan provided. There is a lovely garden in the centre which, as Eike proudly claims, has the only outdoor cinema on the island (a good projector and a laptop being the backbone to this claim)!

There is a fully equipped kitchen and dining area –  however many volunteers are pleased to find that eating out can often be cheaper and easier. There are many local restaurants, all supplying excellent local and international food at very cheap prices. Some are even on the beach!

Whyshould I do this?

Learning to dive and experiencing the wonder of the underwater world is high on many bucket lists. Take it one step further and dive with a conscience; help a team of researchers and conservationists on daily diving missions to collect data, complete research and take photographs of the reefs. Not only is this a valuable contribution to marine conservation, it also allows you to enjoy the reefs as something more than a tourist. Learning about the marine world through this project is possibly one of the most exciting lessons you will ever learn!

Our representative

Janina and Eike founded this marine conservation and research facility in 2011. A lovely couple with witty sense of humour, they both speak English, Spanish and German, with a bit of Thai thrown in for good measure. Janina studied Educational Sciences in Germany, and had extensive experience in adult education before she started managing volunteer flow and pretty much everything else on this project. Eike studied Marine Biology and has a long history of volunteering in animal rescue organisations, before he moved into coral reef ecology. His claim is that this move was for the simple reason that corals don’t bite. No matter what your background is, they will be able to impress you with their vast knowledge of nearly everything (or at least point you to the appropriate book), and will make your stay unforgettable. They also know where you can get Bangers and Mash, should you ever get homesick.

Project Story

“This project was set up in 2012 and visited again in 2013. We have been amazed by the contributions that volunteers can quickly make here and how valuable their time is. We are looking forward to getting more volunteers and interns to develop this further”  Says Anne, Destination Manager
