Becoming a Divemaster is the moment where diving stops being just a hobby and starts becoming a profession. It is the first step into the professional world of scuba diving, where responsibility, leadership, knowledge, and awareness all come together. At Oceans 5 Gili Air, the Divemaster Course is designed as a 6–8 week professional training program that goes far beyond ticking boxes or rushing through skills. It is a program built on quality, real experience, and genuine conservation involvement inside the Gili Matra Marine Park.
Oceans 5 Gili Air is not just another dive shop offering professional courses. It is an Instructor Training Center and the first conservation dive center on Gili Air, with a long history of protecting the local marine environment. The Divemaster Course here prepares you not only to guide certified divers and assist instructors, but also to understand why protecting the ocean matters and how to do it properly.
A 6–8 Week Program Designed for Real Growth
The Divemaster Course at Oceans 5 Gili Air takes between six and eight weeks, depending on your experience, confidence level, and personal development. This time frame is intentional. Becoming a Divemaster is not something that should be rushed. It takes time to build awareness underwater, refine buoyancy, improve problem-solving skills, and develop the calm, professional attitude expected from a dive professional.
Throughout the program, Divemaster candidates are fully integrated into the daily operations of the dive center. You are not a number, and you are not watching from the sidelines. You work side by side with experienced instructors, assist on real courses, guide certified divers, and learn how a professional dive center operates on a daily basis.
Because Oceans 5 is an Instructor Training Center, Divemaster candidates are trained with the next step already in mind: becoming a dive instructor. This means higher standards, better preparation, and a strong focus on professionalism from day one.
Conservation Is Integrated, Not Advertised
At Oceans 5 Gili Air, conservation is not a marketing slogan. It is something that has been part of the dive center since its foundation. In 2010, Oceans 5 started as a Reef Check Centre, actively monitoring reef health around the Gili Islands. Over the years, this commitment has grown into long-term cooperation with local and international universities, marine park authorities, and conservation organizations.
Divemaster candidates are expected to take an active role in conservation activities. This includes:
Weekly beach clean-ups, organized since 2010
Reef clean-ups in front of Oceans 5 and in the harbor area
Algae boom removal, addressing increasing algae outbreaks that threaten coral reefs
Supporting ongoing research projects together with Indonesian universities
These activities are not optional extras. They are a natural part of the program because Divemasters are role models. If you guide divers inside a marine park, you must understand its challenges and actively help protect it.
Here, conservation is about action, not social media posts.
Conservation Courses You Can Add to Your Divemaster Program
One of the unique features of the Divemaster Course at Oceans 5 Gili Air is the ability to expand your training with specialized conservation courses. These courses deepen your understanding of marine life and ecosystems and help you become a more knowledgeable, confident professional.
Available conservation courses include:
Marine Ecology
Coral Identification
Fish Identification
Marine Invertebrate Ecology
Nudibranch Ecology
Sea Turtle Ecology
Marine Mammal Ecology
Manta and Ray Ecology
Shark Ecology
These courses are not just theory. They are directly connected to what you see underwater around the Gili Islands. Learning how to identify species, understand behavior, and recognize environmental changes makes you a better guide, a better assistant, and ultimately a better instructor.
For Divemaster candidates planning to continue into instructor training, this ecological knowledge becomes an enormous advantage when teaching specialties or briefing certified divers.
Professional Skill Development Comes First
While conservation plays an important role, the Divemaster Course at Oceans 5 Gili Air is first and foremost a professional training program. You will refine all core Divemaster skills, including:
Perfecting neutral buoyancy and trim
Demonstration-quality dive skills
Dive theory and physics
Mapping and search patterns
Dive planning and supervision
Assisting instructors during real courses
Guiding certified divers safely and confidently
Unlike many locations where Divemaster candidates are kept overweighted “for safety,” Oceans 5 strongly believes in proper weighting and buoyancy control. Candidates are trained to dive efficiently, calmly, and with full environmental awareness.
This philosophy prepares you not just for Gili Air, but for dive centers anywhere in the world.
A Perfect Step Toward Instructor Training
Oceans 5 Gili Air is an Instructor Training Center, and that makes a big difference. Divemaster candidates who plan to become instructors benefit enormously from doing their training here.
By the time you finish your Divemaster Course, you already know:
The dive center layout and facilities
The training pools and open-water sites
The instructors and Course Directors
Daily logistics, equipment handling, and safety procedures
This familiarity reduces stress when entering an Instructor Training Course (ITC). Your skills and knowledge are fresh, your confidence is high, and your mindset is already professional.
For many candidates, the Divemaster Course at Oceans 5 is not the end goal, but the foundation for a long diving career.
Is Gili Air a Divemaster-Friendly Island?
Absolutely.
Gili Air offers the perfect balance for a 6–8 week professional course. Of course, diving is the main focus, but life on the island offers much more.
Besides diving, Gili Air offers:
Yoga and meditation studios
Stand-up paddleboarding and kayaking
Freediving opportunities
Horse riding along the beach
Mini golf and axe throwing
Social events and relaxed beach bars
Occasional parties without the chaos of Gili Trawangan
Gili Air is not a full-on party island. It is calmer, greener, and more connected to local life. You will find real villages, local warungs, and daily interaction with Indonesian culture. Many Divemaster candidates say this connection is what makes Gili Air special.
It is common for people to come for six to eight weeks and stay for years—working, teaching, or even starting their own businesses. Gili Air has a way of doing that to people.
Living Inside a Marine Park Comes with Responsibility
The Gili Islands are part of the Gili Matra Marine Park, a protected area facing increasing pressure from tourism, waste, and coastal development. Oceans 5 Gili Air believes that dive professionals must take responsibility for protecting the environment that gives them their livelihood.
Divemaster candidates learn to think critically about marine park regulations, environmental impact, and sustainable tourism. This mindset stays with you long after the course ends.
Here, you don’t just learn how to dive. You learn why it matters.
More Than a Course – A Transformation
The Divemaster Course at Oceans 5 Gili Air is not about rushing to get a certification. It is about becoming a confident, capable, and environmentally aware dive professional.
You will leave the program with:
Strong professional diving skills
Real-world experience assisting and guiding
Deep ecological knowledge
A clear path toward instructor training
A connection to Gili Air and its community
For many, this course is the beginning of a completely new life direction.
Gili Air is magic—but only if you are open to it.
And at Oceans 5 Gili Air, that magic is built on quality training, real conservation, and respect for the ocean.
