Using Air Faster Than Your Buddy? You finish a beautiful dive around the Gili Islands and look at your pressure gauge. You have 50 bar remaining. Your buddy still has 90 bar, and the Divemaster appears to have barely used any air. Does that mean …
The 27–28 August TCN survey and the announced beach clearance may mark a turning point—but only lasting enforcement will protect the marine park Gili Air, Gili Meno and Gili Trawangan are not simply three popular holiday islands. Together with their surrounding waters, they form Gili …
The equipment is ready. The tanks are on the boat. The water looks inviting, and everyone wants to start diving.
Then the Divemaster begins the dive briefing.
For some experienced divers, this can feel like information they have heard many times before. They already know the common hand signals, understand how to complete a safety stop and have entered the water from dozens of dive boats.
But a dive briefing is not simply a lesson for beginners—and it should never be treated as a formality that must be completed before everyone can jump into the water.
A proper briefing explains how this particular dive will be conducted, with this group, at this site and under today’s conditions.
It turns a collection of individual divers into an organized dive team.
You may have visited the same dive site several times, but you will never make exactly the same dive twice.
The current may be moving in a different direction. Visibility may have changed. The boat may need to use another entry point. The group may include divers with different experience levels or air consumption. Recent marine-life sightings may influence the route.
This is particularly important around the Gili Islands, where many dives are affected by currents.
A briefing at Shark Point will not necessarily be the same as one at Turtle Heaven, Halik, Deep Turbo or the Bounty Wreck. Even a briefing for the same site may change between the morning and afternoon.
Divers Alert Network describes a dive briefing as the moment to explain the site, underwater topography, expected marine life and the instructions needed for everyone to follow the plan.[1]
The purpose is not to repeat generic information. It is to prepare divers for the dive they are about to make.
Divers should know where they are going and what the site looks like underwater.
The guide may describe:
A clear description helps divers mentally visualize the dive before entering the water. When they descend, the environment will feel more familiar, and the guide’s route will make more sense.
The briefing should include the conditions that may affect the dive, including:
Conditions can change, and predictions are not always perfect. The guide may therefore explain more than one possible plan.
For example:
“We expect the current to move north. If the current check shows that it is running in the opposite direction, we will change the entry point and reverse the route.”
That is not uncertainty. It is responsible preparation for a dynamic environment.
Divers need to know how they will enter the water and what will happen immediately afterwards.
The briefing should make clear:
This prevents one diver from descending while their buddy remains on the surface adjusting equipment.
Around the Gili Islands, a negative or prompt descent may occasionally be appropriate for experienced divers at certain sites and in suitable conditions. This procedure should never come as a surprise after someone enters the water. It must be discussed clearly during the briefing and matched to the group’s abilities.
Being part of a guided group does not remove the buddy system.
Every diver should know:
SSI recommends discussing the plan directly with your buddy even when a dive center has already provided a group briefing.[2]
A good buddy relationship begins before the dive, not after a problem occurs underwater.
The group must understand the limits of the dive.
These commonly include:
The guide should also explain whether a buddy team ends the dive together when one person reaches the agreed gas limit.
SSI’s professional briefing criteria include maximum depth, maximum time, gas-management signals, turning points and reserve pressure.[3] These are not minor details; they are part of the dive plan.
A guide asking for a gas reading is not merely collecting information. The answer may determine the route, depth and time remaining.
Most basic scuba signals are widely recognized, but not every diver was trained by the same agency or in the same part of the world.
Divers may also communicate gas differently. Some think in bar, while others use PSI. Even simple number signals can have variations.
A briefing should review the signals that will be important during the dive, such as:
If a signal is unclear on land, it will not become clearer underwater.
Nobody expects an emergency, but every diver should understand what to do if the dive does not proceed according to plan.
The group should know the procedure if a buddy becomes separated.
A commonly taught response is to search briefly in the immediate area before making a controlled ascent and reuniting at the surface. However, local procedures and circumstances can affect the exact plan.
The important point is that everyone agrees on the procedure before entering the water.
A lost-buddy situation becomes more difficult when one diver searches for several minutes, another surfaces immediately and a third person assumes the guide will solve the problem.
Clear planning prevents different people from taking conflicting actions.
Divers should know:
This information should be reinforced through the pre-dive safety check. DAN notes that buddies should understand each other’s weight-release system, alternate air-source location and equipment releases before the dive.[4]
Any diver may end a dive at any time for any reason.
A diver might feel uncomfortable, cold, tired, anxious or simply believe that something is not right. They should never feel that ending the dive will disappoint the group or create a problem for the guide.
The briefing should explain the signal for ending the dive and what will happen afterwards. DAN recommends discussing the possibility of calling a dive during every briefing, including the procedure for returning to the surface, boat or shore.[5]
It is much easier to make a calm decision when the procedure has already been discussed.
A boat briefing and a dive briefing are related, but they are not identical.
Divers should know:
DAN recommends that operators explain their method of accounting for divers, monitor buddy checks and review entry and exit procedures.[6]
At Oceans 5 Gili Air, our boats carry oxygen, first-aid equipment, communication equipment and safety supplies. A roll call is completed before departure, and divers should pay attention when names and groups are checked.
Boat organization may not seem exciting, but it prevents equipment confusion and ensures that every person is accounted for.
At Oceans 5, the main dive briefing is normally given in front of the dive center before guests board the boat.
There are practical reasons for this.
The area is quieter, and the guide can speak to the entire group without competing with engine noise. Divers can ask questions comfortably, and changes to equipment or group organization can be made before departure.
It also allows the team to confirm:
Once the boat approaches the site, the guide can provide a shorter update based on the actual conditions and current check.
This separates the detailed briefing from the final site assessment. Both are important.
A briefing does not replace a buddy check.
The briefing explains the plan. The pre-dive safety check confirms that the divers and their equipment are ready to execute that plan.
Before every dive, buddies should check:
SSI advises that even experienced divers should perform a pre-dive check before every dive.[7] DAN similarly warns that experienced divers can still forget to open a cylinder valve fully, secure a weight pouch or correctly position equipment.[8]
Experience should make a diver more disciplined—not less interested in basic safety procedures.
A diver with 1,000 logged dives may know how to complete a safety stop. That does not mean they know:
Talking through a briefing can also prevent other divers from hearing information they need. DAN’s guidance on dive etiquette specifically advises divers not to talk during the briefing, even when they already know the standard procedures.[9]
Listening is not an indication of inexperience. It is part of professional and respectful dive behaviour.
A responsible briefing should explain how the group is expected to behave underwater.
At Oceans 5, this includes:
Environmental conduct should not be reduced to “do not touch anything.”
Divers need to understand how their position, buoyancy and behaviour affect marine life. A diver does not need to touch coral with their hands to cause damage. Unsecured equipment, vertical positioning and careless fin kicks can also affect the reef.
DAN includes environmental briefings among the important forms of pre-dive communication, recommending clear instructions about actions divers can take to protect the site.[1]
A five-minute explanation before the dive can prevent avoidable damage underwater.
A briefing creates a plan, but it does not remove the need for judgment.
Conditions may differ from expectations. The current may turn, visibility may decrease, another group may occupy the intended route, or a diver may consume gas faster than expected.
The guide may decide to:
Divers should remain close enough to see the guide’s signals and close enough to assist their buddies.
Following the plan does not mean blindly following the original route. It means following the procedures established during the briefing, including how changes will be communicated.
If something is unclear, ask before entering the water.
Useful questions include:
A professional Divemaster will prefer to answer a question on land rather than solve a misunderstanding underwater.
A good dive briefing does not need to be unnecessarily long. It needs to be clear, relevant and specific.
It should tell divers:
At Oceans 5 Gili Air, the briefing is part of the dive—not an obstacle delaying it.
Those few minutes create better communication, stronger buddy teams, safer entries, more controlled dives and less environmental impact.
So, when your Divemaster begins the next briefing, stop assembling your camera, pause the conversation and listen.
You may have heard some of the information before.
But you have not made this dive before.
A proper briefing should cover the dive-site layout, conditions, route, maximum depth, approximate duration, gas-management procedures, buddy teams, hand signals, entry and exit procedures, emergency procedures and environmental behaviour.
Yes. Experienced divers may know standard scuba procedures, but they may not know the local conditions, planned route, entry method, group organization or boat procedures for that particular dive.
The area in front of the dive center provides a quieter environment where everyone can hear the guide, ask questions and make any necessary equipment or group changes. A shorter update can then be provided on the boat after the current and site conditions are checked.
No. The briefing explains the dive plan. The buddy check confirms that both divers understand each other’s equipment and that the equipment is functioning and ready for the dive.
The guide may adjust the entry point, route, depth or dive time. If necessary, the guide can change or end the dive. The original briefing should explain how changes will be communicated.
The guide normally carries and deploys a surface marker buoy for the group. At Oceans 5, all Divemasters and instructors are required to carry an SMB and reel. Certified divers should also develop the ability to carry and deploy their own SMB where appropriate.
Yes. Any diver can end a dive at any time and for any reason. Feeling uncomfortable is already a valid reason. Signal the guide and your buddy and follow the agreed ascent procedure.
Dive operations use different boats, dive sites, equipment arrangements and local procedures. Listen to the briefing even when you are an experienced diver or have dived in the area before.
The Best Dive Site in the Gili Islands “What is the best dive site in the Gili Islands?” It is one of the questions we hear most often at Oceans 5 Gili Air. Some divers arrive with a famous name already written in their logbook: …
The Ocean Doesn’t Start at the Shore When people hear the words marine conservation, they usually look toward the ocean. They think about coral restoration, turtles, sharks, plastic pollution, fishing, anchor damage and divers touching coral. But there is a fundamental problem with that way of …
Shark encounters are one of the highlights of diving around the Gili Islands.
For many divers, seeing their first shark underwater is an experience they will remember for the rest of their lives. Around Gili Air, Gili Meno and Gili Trawangan, divers regularly encounter whitetip and blacktip reef sharks, including juveniles.
But perhaps we need to start asking a different question.
Are we behaving correctly when we encounter them?
A few days ago, we saw something at Halik that made us think seriously about this question.
A group of divers was lying flat on the bottom in front of the shark cave, apparently trying to get photographs of the juvenile sharks.
For Oceans 5 Gili Air, this is exactly the kind of diving behaviour we don’t want to see.
Not from our students.
Not from our certified divers.
And especially not from Divemasters and instructors.
Maybe it is time for the dive community around the Gili Islands to introduce something new:
Shark Etiquette.
When we enter the ocean, we enter the sharks’ environment.
The shark hasn’t entered our dive centre.
We have entered its home.
That distinction is important.
When a juvenile reef shark is resting underneath an overhang or inside a cave, our desire to get a photograph shouldn’t become more important than the animal’s ability to behave naturally.
Responsible shark tourism is not a new idea. WWF, Project AWARE and The Manta Trust developed Responsible Shark and Ray Tourism: A Guide to Best Practice, providing science-based guidance designed to help operators minimize impacts on sharks, rays and their habitats.[1]
Research into shark-diving tourism has also found widespread use of formal codes of conduct among shark-tourism operators. One study reported that 93% of surveyed shark operators had a formal code of conduct and concluded that such codes should define acceptable diver behaviour and appropriate numbers of divers.[2]
So why shouldn’t we consider a simple local Shark Etiquette Code for the Gili Islands?
Halik is one of the best-known dive sites around Gili Trawangan.
Divers visit the area for turtles, beautiful reef scenery and, of course, the possibility of encountering sharks.
At the shark cave, juvenile sharks can sometimes be observed.
And that creates a temptation.
A diver wants a better photograph.
Then another diver moves closer.
Someone goes down to the bottom.
Another diver follows.
Soon, instead of observing the sharks from the water column, a group can end up lying on the seabed in front of the place where the animals are resting.
Perhaps nobody intends to harm anything.
But good intentions don’t automatically create good diving behaviour.
For Oceans 5, the principle is simple:
We don’t need to lie on the bottom to watch a shark.
We are scuba divers.
We can hover.
At Oceans 5 Gili Air, we teach our students to dive neutrally buoyant.
That philosophy starts during diver education.
In open water, we don’t want students using the seafloor as their classroom. Skills are performed neutrally buoyant because we believe students should learn from the beginning how real divers should behave underwater.
We recently explained this philosophy in our article Should Dive Students Be Allowed to Touch the Seafloor?[3]
Neutral buoyancy isn’t only about becoming a better-looking diver.
It is conservation.
A diver who can control their buoyancy doesn’t need to grab coral.
They don’t need to kneel on the reef.
They don’t need to lie on the bottom to take a photograph.
And they don’t need the seabed to provide stability while watching marine life.
That becomes particularly important when we encounter animals such as sharks.
There is another important part of this discussion.
Guests copy their dive professionals.
If a Divemaster lies on the bottom to photograph a shark, what message does that give the four divers following them?
That it is acceptable.
If an instructor kneels beside the reef to get a photograph, why should we be surprised when their students do the same thing?
This is why shark etiquette shouldn’t only be aimed at tourists.
It should start with us—the dive professionals.
Divemasters and instructors are not simply underwater tour guides. Our behaviour demonstrates what responsible diving looks like.
If we remain neutrally buoyant, keep an appropriate distance and calmly observe an animal, our divers are much more likely to do the same.
Professional behaviour creates diver behaviour.
We have dive briefings.
We have safety procedures.
We discuss currents.
We discuss maximum depths.
We discuss buddy systems.
We explain entry and exit procedures.
So why shouldn’t we spend another minute explaining how to behave when we encounter sharks?
A simple Gili Islands Shark Etiquette could become part of the dive briefing at sites where sharks are regularly encountered.
It doesn’t need to be complicated.
1. Stay neutrally buoyant
Observe sharks from the water column. Don’t deliberately lie, sit or kneel on the seabed to get closer.
2. Give sharks space
Don’t crowd a resting shark or position a group directly around its shelter.
3. Never chase a shark
If the shark swims away, let it swim away. An encounter should happen on the animal’s terms.
4. Never touch
Sharks are wild animals, not underwater attractions.
5. Don’t block their route
Always give the animal an easy way to move away from divers.
6. Stay calm
Avoid sudden movements and unnecessary excitement. International shark-encounter guidance similarly recommends remaining calm, staying with the group and never deliberately touching, harassing or attracting sharks.[4]
7. The photograph comes second
Don’t sacrifice buoyancy, environmental awareness or responsible behaviour for a picture or video.
8. Divemasters and instructors lead by example
The professional should demonstrate the behaviour expected from the group.
9. Brief before the dive
If sharks are likely to be encountered, explain the etiquette before entering the water—not after something has already happened.
10. Observe—don’t interfere
The objective should be to watch natural behaviour, not change that behaviour to create a better encounter.
This might be the most important message.
A shark cave is not an underwater photo studio.
The sharks are not there for us.
They haven’t positioned themselves underneath an overhang so divers can create better Instagram content.
When we encounter them, we are fortunate enough to witness a small part of their natural lives.
Our objective should therefore be:
Leave the shark behaving exactly as it was before we arrived.
That is a very different philosophy from:
How close can I get?
And perhaps that simple change in mentality is what responsible shark diving really requires.
Oceans 5 Gili Air operates within the Gili Matra Marine Protected Area.
For us, supporting marine conservation doesn’t only mean participating in occasional projects.
We support research and data collection around the Gili Islands and work with organizations and institutions including Indonesian government authorities and the University of Mataram.
Scientific research is important.
Data collection is important.
Monitoring reefs is important.
But conservation also happens during an ordinary 60-minute recreational dive.
Every time a Divemaster tells somebody not to touch the reef, that is conservation.
Every time an instructor teaches a student proper buoyancy, that is conservation.
Every time a photographer decides not to chase an animal for a better picture, that is conservation.
And every time a group observes a shark without disturbing it, that is conservation.
Green Fins similarly approaches environmental responsibility as something that should be integrated into everyday marine-tourism operations. Its Code of Conduct contains environmental standards covering operators, staff and tourists, both above and below the water.[5]
We don’t think this should necessarily become an “Oceans 5 rule.”
It could become something much more useful.
Imagine if dive centres around Gili Air, Gili Meno and Gili Trawangan agreed on a simple shark etiquette.
Different dive centres.
Different training organizations.
Different instructors.
Different Divemasters.
But the same message.
When we encounter sharks:
Respect their space.
Remain neutrally buoyant.
Don’t touch the bottom unnecessarily.
Don’t chase.
Don’t surround.
Don’t block.
Don’t disturb.
Observe.
If every Divemaster included those principles in their briefing, thousands of divers visiting the Gili Islands every year could hear the same conservation message.
That is how a small idea can create a much larger impact.
There is another benefit.
Responsible behaviour doesn’t necessarily make a shark encounter less exciting.
It may make it better.
A group of calm, neutrally buoyant divers observing from an appropriate position is very different from several divers crawling towards an animal with cameras.
Responsible shark tourism guidelines internationally are designed around exactly this principle: providing memorable experiences while reducing impacts on animals and habitats.[1]
The goal shouldn’t be getting as close as possible.
The goal should be creating an encounter where our presence matters as little as possible to the shark.
The incident we saw at Halik isn’t about attacking another dive centre or blaming individual divers.
It should start a conversation.
We all operate in the same marine environment.
We all benefit from healthy reefs.
We all benefit when divers see turtles, sharks, rays and other marine life.
And therefore we all share some responsibility for how that environment is treated.
At Oceans 5 Gili Air, our position is clear.
We don’t want our Divemasters or instructors lying on the bottom in front of a shark cave.
We don’t want our students learning that behaviour.
We want our divers neutrally buoyant.
We want sharks to have space.
And we want marine-life encounters to happen with as little interference as possible.
Perhaps it is time to take the next step.
Let’s introduce Shark Etiquette around the Gili Islands.
Not because sharks need another rule written about them.
Because sometimes we humans need rules to remind us how to behave around wildlife.
The sharks were here before our dive centres.
The least we can do is behave respectfully when we visit them.
Shark etiquette is a simple set of behavioural guidelines explaining how divers and dive professionals should act when encountering sharks. Its purpose is to reduce disturbance, protect the surrounding environment and encourage responsible wildlife tourism.
At Oceans 5 Gili Air, we believe they shouldn’t. Divers who have adequate buoyancy control can observe sharks while remaining neutrally buoyant. Deliberately lying on the seabed simply to get closer or obtain a photograph is unnecessary.
Neutral buoyancy allows divers to maintain their position without using the seabed for support. It also helps them maintain an appropriate distance, control their movements and avoid unnecessary environmental contact.
We believe so. At dive sites where shark encounters are reasonably likely, a short explanation before entering the water could establish expectations for the entire group.
No. In many ways it is even more important for Divemasters and instructors because guests frequently copy the behaviour demonstrated by dive professionals.
No. Halik started this particular discussion, but the principle can apply anywhere around Gili Air, Gili Meno and Gili Trawangan where divers encounter sharks.
Perhaps the simplest rule is:
Observe without interfering.
If the shark has to change its behaviour because we want a photograph, we should ask ourselves whether we are already too close.

Marine conservation has become an increasingly important part of the diving industry. Dive centres organise beach clean-ups, participate in coral restoration projects, share conservation messages on social media and encourage divers to behave responsibly underwater.
At Oceans 5 Gili Air, we believe all of these things are important. But we also believe conservation has to go further.
For us, conservation is not something we do only when funding is available. It is not something we organise because it creates a good photograph for social media. And it is not something that should stop when a project or grant ends.
Oceans 5 invests its own money, boats, equipment, facilities and staff time into marine conservation because the ocean surrounding the Gili Islands is directly connected to everything we do.
Our business depends on a healthy marine environment.
So why shouldn’t protecting that environment be part of the cost of running our business?
Oceans 5 Gili Air is located inside one of Indonesia’s most popular diving destinations. Gili Air, Gili Meno and Gili Trawangan are surrounded by the Gili Matra marine conservation area, which covers approximately 2,268 hectares.[1]
Thousands of visitors come to the Gili Islands because of the ocean.
They come to see turtles.
They come to dive coral reefs.
They come to snorkel.
They come because they want to experience the underwater world.
Without a healthy marine environment, the Gili Islands would be a very different tourism destination.
For a dive centre, the connection is even more obvious. Almost everything we do depends on the ocean. Our Open Water students train there. Our certified divers explore it. Our Divemaster candidates learn to guide there, and our SSI Instructor Training Course candidates learn how to introduce future generations of divers to it.
The reef is therefore not something separate from our business.
It is one of the foundations of our business.
That creates responsibility.
Many conservation organisations depend on grants, donations and sponsorships. There is nothing wrong with that. Large scientific and conservation projects can require significant funding, and external financial support can make important research possible.
But there is also a problem if every conservation activity has to wait until somebody provides money.
Sometimes action is needed now.
A researcher may need access to a boat.
University students may need diving equipment.
Scientists may need tanks, guides or logistical assistance.
A survey may need to be conducted.
An environmental problem may need to be investigated.
A beach needs cleaning whether there is a sponsor or not.
At Oceans 5, we don’t believe our first question should always be:
“Who is going to pay for it?”
Sometimes the better question is:
“What can we do?”
And if we have the boat, tanks, equipment, people and facilities available, why wouldn’t we use them?
One of the best examples of this philosophy is our cooperation with the University of Mataram.
Oceans 5 has worked with the university to support marine research and education around the Gili Islands. The partnership has enabled university students and researchers to conduct surveys around Gili Air, Gili Meno and Gili Trawangan.[2][3]
For Oceans 5, supporting this work isn’t simply about providing money.
A dive centre has resources that can be extremely valuable to marine scientists.
We have boats.
We have compressors.
We have scuba tanks.
We have diving equipment.
We have experienced dive professionals.
We have classrooms.
We have swimming pools.
And, perhaps most importantly, we operate on the ocean every day.
Providing access to those resources can significantly reduce the practical barriers to marine research.
That is where a dive centre can make a real contribution.
We also believe conservation should help develop local knowledge.
Indonesia contains some of the most biologically important marine ecosystems on Earth. Long-term protection of those ecosystems requires Indonesian marine scientists, conservationists, dive professionals and local communities to be directly involved.
This is why Oceans 5 supports Indonesian university students in developing practical marine knowledge.
Students don’t only need textbooks.
They need to see coral reefs.
They need to identify species underwater.
They need to understand diving.
They need to conduct surveys.
They need to understand how scientific methods work in real marine environments.
Combining academic education with practical underwater experience can create a much stronger connection between science and conservation.
For Oceans 5, investing in these students is an investment in the future of Indonesian marine conservation.
The waters surrounding the three Gili Islands are not simply recreational dive sites. They form the Gili Matra national marine conservation area, managed under Indonesia’s marine conservation framework. Indonesia’s Ministry of Marine Affairs and Fisheries identifies Gili Matra as a national marine conservation area under BKKPN Kupang.[1]
Oceans 5 believes dive operators working inside a marine protected area should cooperate with the organisations responsible for managing it.
That means communication.
It means following regulations.
It means reporting observations.
And when possible, it means helping.
Dive centres have something extremely valuable: daily eyes underwater.
Our instructors and Divemasters dive the reefs constantly. We can notice changes.
Maybe there is unusual algae growth.
Maybe coral conditions change.
Maybe rubbish appears at a particular location.
Maybe there is fishing activity where it shouldn’t be.
Maybe something simply looks different from six months earlier.
Observations are not automatically scientific conclusions. That distinction is extremely important.
But observations can create questions.
And those questions can lead to research.
The recent expansion of Halimeda around parts of Gili Trawangan demonstrates why this approach matters.
We observed areas where Halimeda had expanded considerably. Together with other stakeholders, we investigated affected areas and experimented with removing algae from selected locations to observe what happened.
But as the affected area expanded, something became increasingly clear:
Simply removing the algae isn’t a realistic long-term solution.
The important question is not only how to remove it.
The important question is:
Why is this happening?
We currently should not pretend that we know the answer.
There may be different environmental factors involved, and determining those factors requires proper scientific research.
That is why Oceans 5 supports further research, including investigation of water quality and environmental conditions around the affected reefs.
Research costs money.
Boats cost money.
Fuel costs money.
Tanks need filling.
Equipment requires maintenance.
People need transportation.
But waiting until somebody somewhere creates a grant doesn’t help us understand what is happening today.
If we can help research happen sooner, we believe we should.
There is sometimes a tendency to associate marine conservation mainly with coral planting.
Coral restoration can certainly play a role in conservation, but healthy reefs depend on a much larger system.
Water quality matters.
Waste management matters.
Coastal development matters.
Boat activity matters.
Fishing pressure matters.
Tourism numbers matter.
Diver behaviour matters.
Education matters.
Scientific monitoring matters.
Government regulation matters.
A coral nursery cannot solve every environmental problem.
Sometimes conservation means restoring something that has already been damaged.
But conservation should also mean understanding why the damage happened in the first place.
Prevention can be much more effective than repairing damage afterwards.
Not every conservation activity requires scientists or research projects.
Sometimes conservation is much simpler.
Every Friday, Oceans 5 organises a beach clean-up around Gili Air.
Our Divemaster candidates help organise these activities, and staff, tourists, divers, local residents and volunteers can participate.
Over time, these clean-ups remove significant quantities of plastic, glass, fishing equipment, metal, clothing and other rubbish from beaches and coastal areas. Previous Oceans 5 clean-up activities have removed dozens of kilograms of waste at a time.[4]
Does one beach clean-up solve the global plastic problem?
Of course not.
But that doesn’t mean we shouldn’t do it.
If everyone waited for someone else to solve a problem completely, very little would ever happen.
Financial support is only one part of our conservation philosophy.
How we teach scuba diving is equally important.
Oceans 5 teaches students to perform skills neutrally buoyant in open water rather than routinely kneeling on the seabed.
Why?
Because this is how divers should actually dive.
Green Fins environmental guidelines encourage divers to maintain good buoyancy, avoid stirring sediment and stay clear of reefs. They specifically discourage touching, kicking, kneeling or lying on coral.[5]
So why would we build dependency on the bottom into someone’s initial diving education?
If we want divers to protect reefs, responsible behaviour should begin during their first course.
The same philosophy applies during our SSI Instructor Training Courses.
Instructor candidates should be able to control themselves neutrally buoyant while demonstrating skills. They should learn to position students without relying unnecessarily on the seabed and should understand their responsibility as future role models.
Green Fins recommends that dive professionals promote good buoyancy, environmentally responsible diving and regular participation in marine monitoring and clean-ups.[6]
For us, those ideas belong inside diver education.
There is another reason Oceans 5 invests directly in conservation.
We want conservation to continue even when nobody is watching.
It is easy to organise an environmental event when cameras are present.
It is easy to post a photograph of people holding bags of rubbish.
It is much harder to make conservation part of normal business operations year after year.
That is the difference we are trying to create.
Of course we communicate about conservation. We actually believe dive centres should talk about it. Sharing information can encourage divers and other businesses to become involved.
But communication should follow action.
Not replace it.
A dive centre might think:
“We aren’t scientists. What can we really do?”
Actually, quite a lot.
A dive centre already has much of the infrastructure needed to support marine conservation.
We have access to dive sites.
We have boats.
We have people underwater.
We have compressors and cylinders.
We have experienced professionals.
We meet hundreds or thousands of divers every year.
We train new divers.
We train Divemasters.
We train instructors.
That creates an enormous opportunity.
Imagine if every dive centre in a marine protected area dedicated even a small percentage of its resources to monitoring, education, research support and environmental activities.
The combined effect could be significant.
There is no reason to pretend that conservation has no economic dimension.
Healthy reefs are good for our business.
We want turtles.
We want healthy coral.
We want abundant fish.
We want clean beaches.
We want good water quality.
We want future generations to travel to the Gili Islands and experience the underwater world that divers enjoy today.
Protecting the marine environment therefore protects both nature and the long-term future of tourism.
Green Fins itself recognises the relationship between environmentally responsible diving and sustainable marine tourism, establishing standards designed to reduce the negative impacts of diving and snorkelling operations on marine ecosystems.[6][7]
For a dive centre, environmental responsibility and economic sustainability don’t have to compete with each other.
Over the long term, they depend on each other.
So why does Oceans 5 invest its own money in marine conservation?
Because we live here.
Because we dive here.
Because our staff work here.
Because our business depends on these waters.
Because the Gili Matra Marine Park gives us an extraordinary environment in which to operate.
And because waiting for somebody else to take responsibility isn’t enough.
We will continue cooperating with universities, government organisations, conservation groups, students, researchers and the local community.
Sometimes that means providing a boat.
Sometimes tanks.
Sometimes diving equipment.
Sometimes staff.
Sometimes education.
Sometimes money.
And sometimes it simply means showing up and helping.
Businesses normally understand investment.
We invest in boats because we need them in the future.
We maintain compressors because we need reliable air.
We train staff because we want better instructors and Divemasters.
We maintain our swimming pools because they are essential for teaching.
So why wouldn’t we invest in the environment on which our entire diving operation depends?
For Oceans 5 Gili Air, marine conservation isn’t separate from running a dive centre.
It is part of running a responsible dive centre.
The reefs around the Gili Islands have provided Oceans 5 with a place to teach, dive, work and build a business.
Investing some of what we earn back into protecting and understanding that environment isn’t charity.
It is responsibility.
Oceans 5 believes that a dive centre benefiting economically from the marine environment also has a responsibility to help protect it. Instead of making every conservation activity dependent on grants or donations, Oceans 5 can contribute boats, tanks, equipment, staff time, facilities and direct financial support when appropriate.
Yes. Oceans 5 cooperates with the University of Mataram and supports students and researchers conducting marine surveys and conservation-related activities around the Gili Islands.[2][3]
Yes. Gili Matra is a national marine conservation area managed within Indonesia’s marine conservation system under BKKPN Kupang.[1] Oceans 5 believes communication and cooperation between dive operators, scientists, authorities and local stakeholders are essential for effective marine conservation.
Coral restoration can be valuable, but it addresses only part of the problem. Reef health is influenced by water quality, pollution, coastal development, tourism pressure, fishing, temperature, diver behaviour and many other factors. Sometimes understanding and preventing the cause of degradation is more important than repairing the visible damage afterwards.
Oceans 5 has participated in observations and practical interventions in affected areas. However, because the affected area has become extensive, simply removing Halimeda isn’t considered a realistic long-term solution. Oceans 5 supports further scientific investigation to better understand environmental conditions and potential causes. Until research provides evidence, Oceans 5 does not want to speculate about the cause.
Yes. One of the easiest ways is to participate in the regular beach clean-ups. Divers can also contribute simply by following environmentally responsible diving practices: maintaining good buoyancy, keeping equipment away from the reef, avoiding contact with marine life and respecting marine park regulations.
Because neutral buoyancy is how divers should behave underwater. Teaching skills without unnecessary contact with the seabed helps students develop buoyancy control from the beginning and reduces their potential impact on the marine environment. This approach is consistent with environmental best practices promoted by Green Fins.[5][6]
Yes. Oceans 5 believes dive professionals should be environmental role models. Divemaster and instructor candidates are not simply learning how to pass assessments. They are learning how to lead and educate future divers. Environmental awareness, good buoyancy, responsible behaviour and respect for the marine environment should therefore be part of professional dive education.
Because observation and scientific evidence are different things. Divers may notice changes underwater, but determining why those changes are happening requires systematic research. Monitoring programmes such as Reef Check demonstrate how long-term data collection can help scientists and managers understand changes in reef ecosystems.[8]
The future of scuba diving around the Gili Islands depends on healthy marine ecosystems. Investing in research, education, monitoring and responsible diving practices helps protect the natural environment while also supporting the long-term sustainability of the local diving and tourism economy.
