Responsible Diving in the Gili Islands
The Gili Islands are one of Indonesia’s best-known scuba-diving destinations. Warm tropical water, coral reefs, sea turtles, reef sharks and a huge variety of marine life attract divers to Gili Air, Gili Meno and Gili Trawangan throughout the year.
But enjoying this underwater world comes with a responsibility.
The three Gili Islands are surrounded by the Gili Matra marine conservation area. When we enter the water here, we are not simply visiting another dive site. We are diving inside a protected marine environment.
So what does responsible diving in the Gili Islands actually mean?
It is much more than not throwing plastic into the ocean.
Responsible diving begins with how we control our bodies underwater, how we interact with marine animals, how dive professionals lead their groups and how the diving industry contributes to protecting the environment on which it depends.
Responsible Diving Starts With Buoyancy
One of the simplest ways a diver can protect a coral reef is also one of the most fundamental scuba skills:
Good buoyancy.
A diver who is neutrally buoyant can move over a reef without touching it. There is no need to stand on the bottom, hold onto coral or use the reef to maintain position.
Unfortunately, poor buoyancy can have consequences.
A fin kick can hit coral. A dangling pressure gauge can drag across the reef. A diver concentrating on a camera can slowly descend until their knees or fins make contact with the bottom.
One accidental contact might seem insignificant.
But imagine hundreds of divers making the same mistake.
That is why we believe neutral buoyancy is marine conservation.
At Oceans 5 Gili Air, this philosophy starts during diver training. Skills are taught with an emphasis on neutral buoyancy rather than making kneeling on the bottom the normal position for learning scuba skills.
Conservation doesn’t have to begin with a major environmental project.
Sometimes it begins with learning how to hover.
Look at Marine Life — Don’t Interfere With It
One of the great attractions of diving around the Gili Islands is marine life.
Sea turtles are particularly common.
For many divers, swimming alongside a turtle becomes one of the most memorable moments of their holiday.
But there is an important distinction between observing an animal and interfering with an animal.
A responsible diver doesn’t chase a turtle to get closer for a photograph.
They don’t block its direction of travel.
They don’t touch its shell.
They don’t attempt to feed it.
They simply watch.
The same principle applies to sharks, rays, octopuses, moray eels, nudibranchs and every other animal we encounter.
If you are interested in why turtle encounters are so common here, read Why Do the Gili Islands Have So Many Turtles?.
A good wildlife encounter should end with the animal behaving exactly as it was before we arrived.
Your Dive Guide Matters
Responsible diving isn’t only the responsibility of the customer.
Dive professionals have an enormous influence on how divers behave underwater.
Imagine following a Divemaster who grabs coral to stop in current, kneels on the reef while looking for marine life or chases a turtle to show it to the group.
What message does that send?
Now imagine following a guide who maintains excellent buoyancy, keeps an appropriate distance from the reef, approaches animals calmly and intervenes when somebody in the group is about to damage coral.
That behaviour also sends a message.
Dive professionals are role models.
This is one reason we believe your dive guide can matter more than the dive site.
A great dive guide doesn’t only find interesting marine life.
A great guide helps protect it.
The Gili Islands Are a Marine Conservation Area
It is easy to forget that the famous dive sites around Gili Air, Gili Meno and Gili Trawangan aren’t simply tourism attractions.
They are part of Gili Matra, a nationally protected marine conservation area.
This means conservation should influence the way tourism operates around the islands.
Divers should understand that coral reefs, seagrass, marine animals and coastal ecosystems are not unlimited resources.
For visitors wanting to understand the area in greater depth, Marine Conservation Society provides information about marine conservation, responsible diving, environmental issues and the protection of the Gili Islands.
You can also learn more specifically about responsible diving in the Gili Islands and why everyday diver behaviour matters inside a protected marine environment.
Responsible Diving Starts Before You Enter the Water
A responsible dive doesn’t begin when you descend.
It starts with preparation.
Equipment should be correctly fitted and streamlined. Gauges, alternate air sources and accessories shouldn’t hang below the diver where they can drag across coral.
Weights should be appropriate.
A diver carrying far too much weight may find buoyancy control more difficult and is more likely to make contact with the bottom.
The dive briefing also matters.
Divers should know what environmental conditions to expect, what marine life may be encountered and how to behave around it.
A briefing isn’t just about maximum depth, dive time and hand signals.
It is an opportunity to establish the environmental standards expected during the dive.
Don’t Kneel on Coral
This sounds obvious.
Yet contact with the bottom remains one of the most preventable impacts of recreational diving.
There is generally no reason for a certified diver to kneel on a coral reef.
Even during training, divers can learn many skills while neutrally buoyant.
This creates an important habit.
Instead of thinking:
“I go to the bottom when I need stability.”
The diver learns:
“I control my position using buoyancy.”
That makes them a better diver while simultaneously reducing their environmental impact.
At Oceans 5, this approach is integrated into diver education from beginner courses through professional-level training.
If you’re considering learning to dive or continuing your education, you can explore the scuba-diving courses at Oceans 5 Gili Air.
Responsible Photography
Underwater cameras have transformed recreational diving.
Almost everyone can now return from a dive with photographs and video.
That’s wonderful.
But cameras can also change diver behaviour.
A photographer concentrating on a tiny nudibranch may stop paying attention to their fins.
Some divers become so focused on getting a photograph that they approach an animal repeatedly.
Others try to move animals or touch the reef to create a better composition.
No photograph is worth damaging the reef.
No Instagram Reel is worth stressing a turtle.
No close-up of a shark is worth changing the animal’s behaviour.
The best underwater photographers combine excellent buoyancy with patience.
If the animal doesn’t cooperate, accept it.
There will always be another dive.
Don’t Judge a Dive Only by What You See
Divers sometimes evaluate dives according to a checklist.
Turtle: yes.
Shark: yes.
Ray: yes.
Octopus: yes.
But nature isn’t a zoo.
The best dive site today may not be the best dive site tomorrow.
Current, visibility, season, water temperature and animal behaviour all change.
This is something we discuss in Why Diving Around the Gili Islands Is One of the World’s Most Exciting Underwater Adventures.
Responsible diving also means accepting the underwater world on its own terms.
We don’t need to manipulate nature to make a dive exciting.
Marine Conservation Doesn’t Stop at the Shoreline
There is another important part of responsible diving that is often overlooked.
What happens on land affects the ocean.
Rubbish, wastewater, coastal development and pollution do not necessarily remain on land.
On a small island, the connection between land and sea is particularly important.
That’s why marine conservation around the Gili Islands needs to consider more than what happens underwater.
Visitors who want to understand the wider environmental picture can explore marine conservation in the Gili Islands, including information about the Gili Matra protected area, conservation rules, responsible tourism, education and environmental issues.
At Oceans 5, we also believe businesses benefiting economically from the ocean should contribute to protecting it.
You can read more about Oceans 5’s conservation work and why the dive centre invests its own resources into conservation activities.
Responsible Diving Includes What Happens After the Dive
Your responsibility doesn’t disappear when you climb back onto the boat.
Think about what you consume during your holiday.
Where does your plastic bottle go?
What happens to takeaway packaging?
How much unnecessary single-use plastic do you use?
Small islands have limited space and complicated waste-management systems.
At Oceans 5, our team has organised beach clean-ups on Gili Air since 2010.
The rubbish collected doesn’t magically disappear.
We recently looked at exactly this question in Where Does 30 kg of Rubbish From Gili Air Actually Go?.
Visitors can also join the weekly Oceans 5 beach clean-up.
Every Friday at 17:00.
You don’t need to be an Oceans 5 customer.
You don’t even need to be a diver.
You simply need to turn up and help.
Education Is Part of Conservation
Long-term conservation requires more than changing tourist behaviour.
It requires education, research and local involvement.
Oceans 5 works with Indonesian university students and organisations involved in marine conservation around the Gili Islands.
Students can develop practical diving skills, improve their knowledge of marine species and gain experience collecting data underwater.
This matters.
Indonesia has some of the world’s most important marine ecosystems. Their long-term protection needs Indonesian marine scientists, conservation professionals, dive professionals and local communities.
You can learn more about the educational and community side of this work through Gili Conservation Dive.
Choose Your Dive Centre Carefully
Price is obviously part of choosing where to dive.
But it shouldn’t be the only consideration.
Ask questions.
How many divers will be in your group?
How experienced is the guide?
Does the dive centre teach neutral buoyancy?
How does it treat marine life?
Does the guide intervene when somebody touches coral?
Does conservation actually influence the company’s daily operations, or is it simply a page on the website?
A slightly cheaper dive isn’t necessarily better value if it means larger groups, less attention or lower environmental standards.
We discussed this in The Cheapest Dive Is Not Always the Best Value.
Responsible tourism includes deciding which businesses you support.
Ten Simple Rules for Responsible Diving in the Gili Islands
You don’t need to be a marine scientist to protect the reef.
You can start on your next dive.
- Maintain neutral buoyancy.
- Never stand or kneel on coral.
- Don’t touch marine animals.
- Don’t chase turtles, sharks or rays.
- Keep your fins away from the reef.
- Secure gauges and alternate air sources.
- Never remove shells, coral or marine life.
- Control your position while taking photographs.
- Listen to your dive guide and respect marine park rules.
- Leave the underwater world exactly as you found it.
These aren’t complicated rules.
They’re simply good diving.
Responsible Diving Is Better Diving
There is sometimes a perception that environmental rules restrict the diving experience.
We see it differently.
A diver with excellent buoyancy is a better diver.
A photographer who can hover without touching the reef is a better underwater photographer.
A diver who calmly observes a turtle instead of chasing it will often have a longer and more natural encounter.
A Divemaster who protects the reef while guiding is a better dive professional.
Responsible diving doesn’t take anything away from scuba diving.
It improves it.
Protecting the Gili Islands One Dive at a Time
The reefs around Gili Air, Gili Meno and Gili Trawangan provide livelihoods, tourism, recreation and extraordinary underwater experiences.
Protecting them requires governments, scientists, communities, conservation organisations and businesses.
But it also requires divers.
Every dive is a choice.
You can touch the reef or hover above it.
You can chase the turtle or watch it.
You can ignore your dangling equipment or secure it.
You can treat the ocean as an attraction—or recognise that you’re a visitor in a living ecosystem.
At Oceans 5 Gili Air, we choose the second approach.
