Talking About Gili Air in 2026 (And Not Bali) In 2026, something interesting is happening in Indonesia’s travel scene. For years, Bali dominated the spotlight as the ultimate tropical destination. From surf culture to yoga retreats and luxury villas, Bali has been the go-to island for travelers …
Was It Worth It? Becoming a dive instructor is one of those dreams many people think about when life starts to feel too structured, too stressful, or too predictable. You sit behind a desk, answer emails, look at the clock, and wonder if this is …
The coral reefs surrounding the Gili Islands have long been among the most accessible and rewarding dive destinations in Southeast Asia. Crystal-clear waters, healthy reef systems, and regular encounters with turtles and reef sharks made these islands a magnet for divers and snorkelers from around the world.
But if you have been diving here for years—as we have at Oceans 5 Gili Air—you will know that the underwater world is not the same as it used to be.
This is not a story about one single event. It is a gradual shift, built up over decades. A series of changes that, when put together, tell a clear story: the reefs around the Gilis are under pressure.
To understand what is happening today, we need to look back.
Around the year 2000, divers regularly encountered grey reef sharks around the Gilis. These were not rare sightings—they were part of the ecosystem. But over time, they disappeared.
In 2008, large groups of mature white tip reef sharks vanished. Again, not overnight, but steadily enough that today, seeing one is no longer the norm but the exception.
By 2010, zebra sharks—once part of the marine life diversity—were gone.
In 2015, something else changed. The large schools of bumphead parrotfish, powerful reef grazers that play a critical role in reef health, disappeared from the area. These fish are essential: they control algae growth and help maintain the balance between coral and algae on reefs.
Then came 2022, when a turtle disease outbreak affected populations around the islands. Turtles, one of the most iconic species of the Gilis, suddenly showed signs of stress and illness.
In 2025, divers began noticing an unusual increase in Halimeda algae. By 2026, this had escalated into a much larger outbreak, with certain reef areas increasingly dominated by this calcifying green algae.
And this timeline doesn’t even include global coral bleaching events driven by rising sea temperatures.
Each of these moments might seem isolated. But they are not. They are signals.
There is no single cause. Coral reef ecosystems are complex, and when they change, it is usually the result of multiple stressors acting at the same time.
The Gili Air, Gili Meno, and Gili Trawangan are small islands. Their landmass is limited, and so is their capacity to support infrastructure.
Yet in recent years, development has accelerated rapidly. New accommodations, villas, and resorts are being built at a pace that raises serious questions about sustainability.
More rooms mean more tourists. More tourists mean more pressure on water, waste systems, and ultimately, the marine environment.
One of the most visible changes above water is coastal construction.
Beach walls, land reclamation, and building too close to the shoreline disrupt natural coastal processes. Sand movement changes, erosion patterns shift, and sediment can be transported into the ocean.
Sediment is one of the biggest enemies of coral reefs. It reduces light penetration, smothers coral polyps, and creates conditions where algae can thrive instead.
As development increases, so does wastewater.
Without proper treatment systems, nutrients from wastewater seep into the ocean. Elevated nutrient levels change the chemistry of the water, often leading to algal blooms.
The Halimeda algae outbreaks seen in 2025 and 2026 are not random. They are symptoms of a system receiving too many nutrients.
This shifts the balance: instead of coral-dominated reefs, you get algae-dominated systems.
Tourism is the backbone of the Gili Islands. Diving and snorkeling are at the center of that economy.
But more people in the water means more potential for impact:
Even when unintentional, the cumulative effect of thousands of visitors adds up.
Indonesia has clear regulations regarding coastal development and land zoning, especially within marine park areas.
The Gili Islands are part of the Gili Matra Marine Park, a protected area meant to balance conservation and tourism.
However, when regulations are not consistently enforced, or when zoning rules are ignored, development can exceed what the ecosystem can handle.
This is where the real problem begins—not just development, but uncontrolled development.
Rising pH levels and other chemical changes in the water can alter reef ecosystems. Combined with nutrient input and temperature stress, these changes create conditions where corals struggle and algae thrive.
It is easy to look at one missing species and think it is an isolated issue. But reefs are interconnected systems.
Remove one element, and the system shifts.
Remove several, and the entire ecosystem starts to transform.
The disappearance of grey reef sharks, white tips, zebra sharks, and bumphead parrotfish is not just about biodiversity—it is about losing balance.
Let’s be honest: the Gili Islands depend on tourism.
Diving, snorkeling, and beach holidays are the main drivers of the local economy. Without healthy reefs, that economy will suffer.
This is not an environmental issue alone. It is a business issue.
If reefs degrade:
And once that happens, recovery is not quick.
This is the most important question.
At Oceans 5, we believe that sustainability in a marine park cannot rely only on good intentions. It requires structure, regulation, and long-term thinking.
Marine parks around the world already use quota systems to control visitor numbers.
Look at destinations like Sipadan Island or the Galápagos Islands. These are not comparable in every aspect, but they share one key element: they limit access to protect the environment.
A quota system for the Gili Islands would:
It is not about stopping tourism—it is about managing it.
A quota system would also indirectly limit new construction.
If visitor numbers are capped, there is less incentive to build more rooms. This creates a more stable and sustainable economic model instead of the current “wild west” approach.
Indonesia already has laws in place. The issue is enforcement.
Respecting zoning laws, coastal setbacks, and environmental regulations is essential. Without enforcement, even the best policies remain ineffective.
Investing in proper wastewater treatment systems is critical.
Reducing nutrient runoff will directly impact algae growth and help restore the balance between coral and algae.
Better education leads to better behavior underwater.
At Oceans 5, we focus on:
Small actions from individuals can make a big difference when multiplied across thousands of divers.
Collaboration with universities, marine biologists, and conservation organizations provides valuable data and insight.
Long-term monitoring is essential to understand trends and measure the impact of any changes implemented.
The Gili Islands are at a crossroads.
The current path—rapid, largely uncontrolled development—may bring short-term economic gains. But it risks long-term damage to the very environment that makes these islands special.
The alternative is a more controlled, sustainable approach:
It requires cooperation between government, businesses, and the local community.
The changes we have seen over the past 25 years are real. They are measurable, and they are accelerating.
From the disappearance of key species to the rise of algae dominance, the reefs around the Gili Islands are telling us something.
The question is whether we are willing to listen.
Because if we don’t, the future of Gili Air, Gili Meno, and Gili Trawangan as world-class diving destinations is not guaranteed.
But with the right decisions—starting now—we can still protect this marine park for future generations.
And that is a responsibility we all share.
Gili Air Learning to scuba dive is one of those life decisions that stays with you forever. Your first breaths underwater, your first interaction with marine life, and your first feeling of weightlessness will shape how you view the ocean for years to come. That’s …

At Oceans 5 Gili Air, our slogan has always been simple: Diving for Everyone. Since the day we opened our doors, we have believed that scuba diving should be accessible to as many people as possible. On 1 January 2026, Oceans 5 Gili Air switched over to SSI, a worldwide recognized dive organization known for its modern teaching systems and global network. Only a few months later, Oceans 5 Gili Air has taken another important step by also becoming a Diverse Ability Dive Center.
This new partnership is a natural continuation of what Oceans 5 has stood for from the beginning. For years, Oceans 5 Gili Air has worked with the idea that scuba diving should not be limited by age, background, or physical challenge. By joining Diverse Ability, Oceans 5 is strengthening that philosophy and creating even more opportunities for divers and dive professionals.
Diverse Ability is an organization that focuses on making scuba diving accessible for people with physical or cognitive disabilities. Their goal is not only to help disabled divers experience the underwater world, but also to create proper educational systems for instructors and dive centers so that adaptive diving becomes a real and professional part of the dive industry.
Many dive organizations offer a specialty or workshop for instructors who want to learn how to teach disabled divers. While these programs can be useful, Diverse Ability takes things a step further. Instead of offering only an add-on course, they have developed specific programs around existing dive organization courses. This means that disabled divers can follow structured programs that are adapted to their individual abilities while still working within recognized diver education systems.
This approach makes adaptive diving more professional, more complete, and more accessible. It is not only about assisting someone in the water. It is about creating a teaching system that gives people the opportunity to learn, grow, and enjoy scuba diving in a safe and supportive environment.
Becoming a Diverse Ability Dive Center is not something new or unusual for Oceans 5 Gili Air. Since the opening of the dive center, Oceans 5 has promoted the idea of inclusion through its slogan Diving for Everyone. For years, Oceans 5 was also part of Disabled Divers International, showing a long-term commitment to adaptive diving and accessible teaching methods.
The partnership with Diverse Ability is therefore a logical next step. Oceans 5 is now an SSI dive center on Gili Air, and with this additional connection to Diverse Ability, the dive center is expanding its ability to teach a wider range of students in a more structured way. It is not just about welcoming disabled divers; it is about being trained and prepared to offer programs that truly work for them.
At Oceans 5 Gili Air, quality teaching has always been more important than volume. Small groups, professional standards, and personalized education are already part of the daily routine. Those same values are essential when it comes to adaptive diving. Every student is different, and every instructor should be flexible enough to adjust their teaching methods to the person in front of them.
For any dive professional, becoming a Diverse Ability Instructor is a great way to raise the bar. Adaptive diving is not only about working with disabled divers. It is also about becoming a better, more creative, and more flexible instructor.
Every experienced instructor knows that no two students are the same. Some students learn quickly through demonstration, others need more explanation, and some need more time and patience. Teaching disabled divers takes this understanding to an even higher level. Instructors need to think differently, communicate better, and adapt their methods to suit each student’s needs.
That makes a Diverse Ability Instructor more employable in the dive industry. Dive centers around the world are increasingly looking for instructors who can offer more than standard entry-level courses. An instructor who understands adaptive teaching methods can work with a wider variety of guests and help make diving more inclusive for all.
In other words, learning to teach adaptive programs does not only benefit disabled divers. It also improves the overall quality of the instructor.
One of the most exciting developments is that Oceans 5 Gili Air now has a Diverse Ability Instructor Trainer. This means that the dive center is not only able to support adaptive diving, but will soon also be able to train dive professionals who want to become Diverse Ability Instructors themselves.
The Instructor Trainer brings practical experience from large events for disabled divers in Bali, Lombok, and Java. This real-world experience is essential. Adaptive diving is not something that can only be learned from theory. It requires understanding, problem-solving, and practical teaching techniques that come from actual experience in the field.
With this knowledge now available at Oceans 5 Gili Air, future instructor courses will offer a valuable opportunity for dive professionals who want to expand their teaching abilities.
Diverse Ability Instructor Courses at Oceans 5 Gili Air will be announced soon. These courses are expected to run over 2 to 3 days and will give dive professionals the knowledge and practical skills needed to work with disabled divers in a safe, respectful, and effective way.
During the course, participants will learn more about:
These skills are highly relevant in the modern dive industry. As more dive centers focus on quality, inclusion, and professionalism, instructors with adaptive diving knowledge will stand out from the crowd.
The diving world is changing. Divers today are looking for professional dive centers that care about education, safety, the environment, and inclusion. Oceans 5 Gili Air has already built a strong reputation on these foundations. By becoming a Diverse Ability Dive Center, Oceans 5 is continuing to move with the future of diving rather than staying behind.
Adaptive diving should not be seen as a niche part of the industry. It should be recognized as an important part of what modern dive education can and should be. The underwater world is something special, and more people should have the opportunity to experience it. With better programs, better-trained instructors, and better understanding, adaptive diving can open the ocean to many more people.
For Oceans 5 Gili Air, this is not just a marketing message. It is a continuation of a long-standing belief that diving should be accessible, professional, and enjoyable for everybody.
By becoming a Diverse Ability Dive Center, Oceans 5 Gili Air is showing once again that the slogan Diving for Everyone is more than just words. It is a philosophy that shapes the way the dive center teaches, grows, and develops.
After switching to SSI on 1 January 2026, Oceans 5 has continued to build a modern and forward-thinking dive center on Gili Air. Joining Diverse Ability is another strong step in that direction. It creates new opportunities for disabled divers, new possibilities for instructors, and a stronger future for inclusive scuba education.
If you are a dive professional and you want to become more flexible, more knowledgeable, and more employable, becoming a Diverse Ability Instructor could be the perfect next step. And soon, Oceans 5 Gili Air will be the place where you can start that journey.

Yesterday evening, staff from Oceans 5 Gili Air, Gili Cares, and a large group of dedicated volunteers joined forces for another successful beach cleanup on Gili Air. Together, between 20 and 30 people collected an impressive 164 kg of rubbish from the harbor area all the way to Villa Karang.
At first, it looked like everyone was collecting only a small amount. A plastic bottle here, a bag there, some cans, paper, and floating debris. But by the end of the evening, the total weight showed the real impact of community action. What seemed like small individual efforts turned into a massive result for the island.
The cleanup took place in the harbor area of Gili Air, a part of the island where rubbish often ends up. Even though the rainy season is almost over, the harbor of Gili Air remains a place where debris washes ashore. Currents, tides, and runoff continue to bring waste into this area, making regular cleanups necessary throughout the year.
Thanks to the hard work of everyone involved, the rubbish was removed before it could spread further, break down into smaller pieces, or end up back in the ocean. Cleanups like this are not only important for the appearance of the island, but also for the health of the marine environment around the Gili Islands.
This successful event was made possible by the teamwork between the staff of Oceans 5 Gili Air, Gili Cares, and all the volunteers who gave up their evening to help protect the island. These cleanups show that conservation is strongest when the local community, businesses, and visitors work together.
One of the highlights of the evening was the recycling effort led by Rama. After the rubbish was collected, Rama separated the plastic bottles, cans, and paper so these materials could be sent for recycling. This extra step is important because it reduces the amount of waste that simply ends up in landfill and helps create a more sustainable system for waste handling on Gili Air.
The harbor of Gili Air is one of the main points where marine debris accumulates. Because of its location, floating rubbish from surrounding areas often ends up along this stretch of beach. During the rainy season this problem becomes worse, but even after the season changes, the harbor remains a collection point for waste.
This is why regular beach cleanups on Gili Air are so important. Every cleanup removes waste before it can damage coral reefs, harm turtles, fish, or seabirds, or break down into microplastics. It is a simple but direct action that has a visible impact on the island and its surrounding marine park.
Oceans 5 Gili Air has been organizing beach cleanups, reef cleanups, and conservation events since 2010. Sixteen years ago, Oceans 5 started its journey with a strong environmental philosophy, and that commitment has never changed.
As the first Reef Check dive center on Gili Air in 2010, Oceans 5 has always believed that a dive center should do more than just take people diving. It should also take responsibility for the environment it depends on. Over the years, Oceans 5 has organized not only beach and reef cleanups, but also conservation talks, support for conservation programs, and long-term environmental partnerships.
What makes Oceans 5 different is its approach to conservation. With an annual budget of 1,500,000,000 IDR funded directly by the owner, Oceans 5 supports environmental and educational projects without asking for grants or donations. Oceans 5 does not want to make a profit out of conservation. Instead, it invests directly in real action.
This budget helps Oceans 5 organize cleanups and conservation events, support Indonesian university students who want to become marine scientists, offer Indonesians the chance to join a free divemaster internship, and build partnerships with organizations such as Marine Conservation Indonesia.
The philosophy is simple: conservation should be genuine. It should not be a marketing trick or a fundraising business model. It should be a real effort to protect the island, support the local community, and create long-term environmental awareness.
If you would like to support real conservation work on Gili Air, one of the easiest ways is to dive or stay at Oceans 5 Gili Air. By choosing a dive center and resort that invests heavily in conservation, education, and community support, you become part of a much larger effort.
Every guest who dives or stays with Oceans 5 helps support weekly beach cleanups, conservation education, marine science opportunities for Indonesian students, and programs that benefit the local community. Oceans 5 believes that tourism and diving should give something back to the island, not just take from it.
The collection of 164 kg of rubbish in just one evening is a powerful reminder that even when each person collects only a little, together the impact can be enormous. The cleanup from the harbor to Villa Karang showed once again that community action works.
For Oceans 5 Gili Air, Gili Cares, Rama, and all the volunteers, this was not just another cleanup. It was another step in a long-term commitment to keep Gili Air cleaner, healthier, and more sustainable for the future.
If you want to be part of real conservation on the island, join a cleanup, dive responsibly, and support businesses that invest back into the environment. That is how long-term change happens on Gili Air.
