Scuba diving is not only about breathing underwater or earning a living by guiding tourists. At Oceans 5 Gili Air, diving is a responsibility. It’s a way to protect the marine environment while educating and empowering future instructors to do the same. Especially on Gili Air—a tropical paradise in the heart of Indonesia’s Gili Matra Marine Park—this responsibility has become more urgent than ever.

As overdevelopment and unchecked tourism increase the pressure on marine ecosystems, the need for environmentally aware dive instructors has never been greater. At Oceans 5, conservation and being a dive instructor are two roles that go hand-in-hand. We don’t just teach you how to dive—we teach you how to lead, protect, and inspire.

The Harsh Reality: Marine Life Under Pressure

The Gili Islands are famous for their stunning coral reefs, sea turtles, and diverse marine life. But behind the idyllic images lies a fragile ecosystem under constant stress. Over the last decade, development around the Gili Islands has expanded rapidly. New accommodations, dive centers, beach clubs, and restaurants have popped up along the coastlines. With this growth came more waste, more wastewater, and more unregulated activities—all putting pressure on the delicate reef systems.

Beach walls were built without considering turtle nesting grounds. Untreated sewage entered the sea. And with more divers and snorkelers entering the water, unintentional damage to coral reefs and marine species increased.

Plastic pollution, ghost nets, and rubbish from nearby islands and boats regularly wash into our waters. On any given dive, you might spot a plastic bag drifting alongside a hawksbill turtle or a ghost net entangled around a coral bommie. What should a diver do in that moment? Swim past and ignore it? Or take action?

Oceans 5’s Answer: Take Action, Always

At Oceans 5 Gili Air, we teach our divers and instructor candidates to take action. That plastic bag you ignore today may choke a turtle tomorrow. That ghost net could smother an entire coral colony in days. The ocean doesn’t need passive visitors—it needs protectors.

This philosophy is at the core of how we operate. From fun divers to professional candidates, we expect everyone who enters the water with us to respect and care for the marine environment. Our instructors lead by example. They don’t touch marine life. They maintain perfect buoyancy. They pick up trash when they see it. And most importantly, they teach others to do the same.

Environmental Awareness Starts with Buoyancy

One of the most fundamental ways a diver can minimize their environmental impact is by having good buoyancy control. That’s why neutral buoyancy is a cornerstone of all our courses at Oceans 5.

Unfortunately, many dive instructors around the world still teach students to kneel on the bottom during skills sessions. This outdated method can crush coral, stir up sediment, and set a poor example for students. It also sends the message that it’s acceptable to rest on the reef.

At Oceans 5, we’ve stepped away from this harmful habit. Our instructors teach their students to hover while performing skills—both in the pool and in the ocean. This technique takes more effort and attention, but it creates better divers and helps protect the environment.

And we don’t just stop with Open Water students. Every candidate in our PADI Instructor Development Course (IDC)learns how to demonstrate skills in neutral buoyancy and how to teach it to their future students. We believe that the best instructors are those who inspire their students to be guardians of the ocean, not just passive participants.

Marine Park Responsibilities: Gili Matra Needs Us

The Gili Islands fall under the Gili Matra Marine Recreational Reserve, a protected area established to conserve the biodiversity of the region. Divers and snorkelers pay a marine park fee to access these waters—but are they truly protecting what they pay to see?

At Oceans 5, we take that responsibility seriously. We know that tourism is both a blessing and a burden for the Gili Islands. While it supports the local economy, it can also harm the very ecosystem it relies on. That’s why our dive center operates with a long-term, conservation-first mindset.

We educate every diver on marine park rules. We enforce a strict no touching, no chasing, no interference policy with marine life. And we organize regular reef and beach clean-ups, encouraging our team, our guests, and our students to join. Our goal isn’t just to keep the reef clean—it’s to change the behavior of those who visit it.

Instructor Training with a Conservation Mission

At Oceans 5, our PADI IDC program is unlike any other in the region. Yes, we teach candidates how to pass the Instructor Examination. But more importantly, we prepare them for a real-world teaching environment that demands leadership, awareness, and ethics.

We believe that every dive instructor is an ambassador of the ocean. What they teach—and how they behave underwater—will influence hundreds, if not thousands, of divers throughout their careers. That’s why our IDC curriculum includes a strong focus on environmental responsibility.

From the first day of the IDC, candidates are immersed in a culture of conservation. They don’t just learn how to demonstrate a mask removal or a controlled emergency swimming ascent. They learn how to model the right behavior underwater and how to guide others to be eco-conscious divers.

Here are just a few ways our IDC Indonesia trains instructors to lead with conservation in mind:

  • Neutral buoyancy skill circuits in open water, not just confined water.

  • Workshops on marine life interaction protocols.

  • Briefings on marine park regulations and their enforcement.

  • Participation in beach and reef cleanups.

  • Lectures on sustainable dive tourism and environmental threats.

  • Opportunities to assist in research with the University of Mataram.

Partnership with the University of Mataram

Education and conservation go hand in hand. That’s why we’ve built a long-standing partnership with the Faculty of Marine Science at the University of Mataram. Each year, we host groups of marine biology students on Gili Air, giving them the opportunity to conduct field surveys and reef assessments.

Our instructor candidates interact with these students, learning from their scientific perspective and gaining insight into coral identification, fish biodiversity, and marine ecosystem health. This cross-pollination of knowledge ensures that our future instructors are not just educators—they are lifelong learners and allies in marine protection.

Oceans 5 also supports the university by providing equipment, boats, and logistics for student research. We believe in building a local foundation for marine conservation that empowers Indonesian scientists and professionals.

The Role of Cleanups in Education

Words are powerful, but action is even more powerful. That’s why we organize weekly beach and reef cleanups, regardless of the number of participants or the weather conditions. These events are not just about removing trash—they are about showing, not telling.

During cleanups, instructor candidates lead by example. They brief volunteers on safe collection techniques, organize buddy teams, and ensure that participants understand the impact of the items they’re collecting. Whether it’s 10 kg or 100 kg of waste, every cleanup ends with reflection: Where did this waste come from? How can we prevent it in the future? What can we change in our own behavior?

These are the kinds of real-life lessons we believe every dive instructor should be equipped to teach.

Role Models the Industry Desperately Needs

There’s a growing demand around the world for dive instructors who do more than teach courses—they inspire change. Tourists and dive centers alike are waking up to the reality that the oceans are in trouble. And they want to work with instructors who understand the gravity of the situation.

At Oceans 5, we train instructors to be role models for the next generation of divers. We teach them that every briefing, every debriefing, and every underwater moment is an opportunity to educate.

  • Will they remind students to secure their gauges and avoid kicking coral?

  • Will they intervene when someone chases a turtle for a photo?

  • Will they calmly explain why we don’t touch anything underwater?

These are not optional qualities. They are essential. Because our oceans can’t afford anything less.

Why It Matters: The Bigger Picture

It’s easy to look at a single piece of plastic or one diver kneeling on the reef and think, “It’s not a big deal.” But when thousands of divers visit the same site every year, those small actions add up.

Marine tourism, if not managed carefully, becomes a destructive force. But if guided by well-trained instructors who prioritize conservation, it can become a powerful tool for education and change.

That’s the mission we pursue every day at Oceans 5 Gili Air: to train dive professionals who see themselves not just as instructors, but as guardians of the marine world.

Final Thoughts: Teaching With Purpose

At Oceans 5 Gili Air, we believe that scuba diving is more than a sport—it’s a chance to connect with nature, protect it, and inspire others to do the same. Our commitment to conservation is not a trend or a marketing tool. It’s the foundation of everything we do.

So the next time you see plastic floating during your dive, or a ghost net wrapped around a coral, ask yourself: What would a true dive professional do? If you’re ready to become the kind of instructor the ocean needs, we’re ready to show you how.

Conservation and instruction—they go hand in hand.
