The islands are surrounded by crystal clear water and views over the volcanos Rinjani (Lombok) and the Angung (Bali).

The people of the islands are original from Sulawesi, East Indonesia.  They came with boat and fount water to drink on this island. They gave the island the name Gili Air. Air means in Bahasa Indonesia Water.

Shark Guardian at Oceans 5

Shark Guardian at Oceans 5

It is a Sunday night with Shark Guardian at Oceans 5 Dive resort, and the front yard is packed with people. Brendon Sing is on stage. “The first time I saw a wild shark was in Sodwina bay, South Africa when I was 16. As a fresh open water diver I went on the reef with 12 meters of water above me. And then I see this majestic reef shark. I’m breathing like a freight train and my arms and legs go wild…  and  the shark is gone, scared of me! At that moment everything changed  for me. Sharks are more afraid of us then we them and they have every right to be.”

IDC Indonesia Oceans 5

Sharks are dominant apex predators in all the oceans

Sharks have survived in the oceans for 400 million years. But now these superb predators that are vital for the worlds ecosystem are facing a serious threat in the form of another predator, humans. Sharks need help.

How Shark Guardian started

Five years ago Brendon together with his wife Elisabeth quit their day jobs as dive professionals and started  to work full time to protect the sharks of the world. In 2013, the work was organised under a UK based charity organisation and Shark Guardian was born. Today Brendon, Elisabeth and their four month old daughter Olivia are travelling around the world to make the people see the importance of sharks. “It all happened naturally, I just talked about sharks cause I love them. It grew and grew and then we said lets give a name for it, and then it became Shark Guardian. We already see the results of our work. We have received letters from parents saying that they learned so much from their kids about sharks that they don’t want to eat shark anymore. We are self funded by raising donations and selling merchandise so that we can go to as many places as possible to give our educational presentations and workshops.”

Oceans 5 idc indonesia

Brendon, Elisabeth and Olivia. Sharkguardian at Oceans 5!

The Shark Guardians have been at Oceans 5 for three times during the last two years. ” We had heard about Sander and the good reputation he has and decided to contact him. The co operation has  been fruitful ever since. We always get a good crowd when we visit Oceans 5. Last time we were here we organised a night dive and went out to Sunset to see the Whitetip reef sharks hunting in the dark, That was really awesome! When I see a shark under water I feel humble and honoured for being in presence  with something that has been around for 400 millions years.”

Eshark project

One of the Shark Guardian projects is called Eshark. For divers it is a great way to participate. By collecting dive log data Shark guardians will be able to provide evidence about the changes in the Shark populations around the world.

“Sharks are dominant apex predators in all the oceans. They are on top of the food chain. If you remove sharks, the species under them will overpopulate and have a damaging domino effect to the whole ecosystem they belong to. A prime example of this can be seen in the US east coast, where  Hammerhead sharks were regularly seen, but are now fished to near extinction. This has lead to an overpopulation of cownose rays which in their turn have destroyed shell fish population which were a major source of income for the fishing industry. More sharks in the oceans means more fish in the oceans. This is already proven with marine sanctuaries where sharks are protected and as a result, all aquatic populations are in better condition.”

After the presentation Brendon and Elisabeth are bombarded by questions.  People are eagerly asking how they could participate. “Media is treating the sharks in a ugly way.Sharks are not cute like dolphins and turtles. But sharks are not after humans, we are not a part of their diet. Shark attacks are unfortunate mistakes. To turn this around, we try to establish more knowledge about sharks, underlining the value of sharks to people.  It is a privilege to see sharks, it is a positive rewarding experience. For dive professionals I have a very simple request: Please pass this message to all your dive students. For divers and non divers  I would ask you to make an important decision not to buy or eat any shark related products. ”

Hammerhead shark at Gili islands!

Hammerhead sharks are a rare sight at Gili Islands. But a few days ago we saw one! Here’s the full story:

On Sunday morning we were on the 8:30 dive boat with Oceans 5. It was not a busy morning, there were only seven divers with boat captain Cakdi on the boat. When we arrived to Sunset, south of Gili Trawangan, the sea was calm, no waves, wind or current.

Arne and Jarle, my Norwegian dive buddies and me got into the water and quickly decended to around 29 meters. From there we started to work our way up to the bummies where we usually see the baby Whitetip sharks. As we were closing to 24 meters I saw a two meter long Whitetip lying on the seabed, getting cleaned by a few Cleaner fish. When we were about three meters away from it, it started to swim. First going around a bummy and then coming back, swimming an eight shape around us. We stopped to witness this amazing sight, Jarle was taking video with his Gopro. We watched this for a good five minutes, enjoying the majestic moves of the shark swimming around us.

When it finally turned away, I watched how it started to swim towards the blue. And then another object in midwater caught my eye. Something big was moving a little bit above me and to the left. There was no doubt about it! A Hammerhead shark came from the shallow part of the reef, maybe two meters above us, three or four meters in front of us. It moved slowly from left to right, right in front of us and continued towards the deep. Jarle saw it, Arne saw it and I saw it. The shape of the head left no space for speculations. The first Hammerhead sighting at Gilis for over two years!

Diving for the first time


It is easy to try scuba diving with Oceans 5 dive resort. pic (c) Nayoung Kim 2015

Diving for the first time is a once in a lifetime experience. For Jurian Gouldwaard it happened the 11th of July 2015. Jurian has been travelling in Asia for some time. He likes to snorkel, chill out and eat good food. After some hectic days in Kuala Lumpur and Jakarta it was an easy choice for him to head towards Gili Air, where there are no cars and public transportation is done with horse and carriage. Meeting old friends and getting familiar with the laid back lifestyle of the paradise island, just a two-hour boat ride away from busy Bali, he was watching at the numerous dive shops all around the island. “I have learned that the Gili islands are one of the worlds top dive locations, and you can really sense it here. There are a lot of dive shops, and there are divers everywhere. Last night I was watching divers doing rescue exercises on the beach while we were waiting for our dinner.”

Diving for the first time

Discover scuba diving is a PADI program designed for people who want to experience the underwater world for the very first time. It is not a course, but a half day experience. The day contains a short theory session and one dive in the pool, where the participants get to know how the equipment works and learn a few problem management skills. And then of course the actual dive, the highlight of the experience. “It was really interesting to take the first breaths under water. It felt like I needed to actively control my breathing to make it happen. But then again, it felt really easy to breath. The air was just flowing in from the regulator”. The maximum depth for the dive is 12 meters.

Oceans 5 Dive Resort pays a lot of attention to deliver the best possible experience for the new divers to be. The group sizes are kept small, always four or less people per instructor. Oceans 5 is a PADI career development centre, which also means that the level of teaching is kept high. “This day was super nice. I will most probably continue to the Open Water course at some point. In the pool this morning we did a lot of skills like clearing the mask and finding the regulator. They were easy for me, it is clear that these “problem management skills” are good to know when you are under water. You can’t go up to the surface every time when you have a little bit of water in your mask. ”

Turtle City

After the pool session we take a little break. At 11:30 we go diving to Turtle City, a dive site that is famous for it’s huge Green turtles. And the turtles are there! For almost 40 minutes we drift under the surface, watching the turtles fly in the ocean together with an ubiquitous amount of colourful fish all shapes and sizes. “That was really cool!” shouts Jurian when we surface near the shores of Gili Meno. ” You see a lot of things under water when snorkelling, but with the dive equipment you can get really close to turtles, watch them eat, sleep and swim up to the surface to breath”

5 tips how to choose a dive shop

5 tips how to choose a dive shop. In this blogpost we look into how to choose a dive shop for your holiday.

If you are interested in diving but not yet a certified diver, please also check a previous blogpost from Oceans 5 dive resorts blog, “How to start scuba diving?

For recreational diver, a dive holiday is the highlight of the year. It is nice to go to new places, to explore new dive sites. To select the holiday destination should be done with care. PML_6261 Once the destination is selected it’s time to start to think about how to select the dive shop in the location. Once in the location, the good old “walk-in and check the vibe” is still a very valid way of making the final decision. Here are five tips how to choose a dive shop and what to take under consideration when selecting the dive shop.

1. How to choose a dive shop? Use the Internet!

pic by

After you have chosen your destination, Google the local dive shops. Check out their web pages, a decent dive shop has also decent web pages. Look out for customer reviews from their own pages, from Tripadvisor and from diving related services, such as Diviac . Send the dive shop an email explaining your schedule and wishes, and have a dialogue with the store. How fast do they answer? Do you get satisfactory answers to your questions? Are they nice? This should help you a lot in your final decision.

2. Big or small?

Should you choose a big dive school or a small store? Both options have their advantages. Usually, bigger stores are more professionally operated, they have their own rental gear, boats, pool and fixed personnel. On the downside, they might be less flexible with schedules, dive sites, or other personal requests. Bigger schools usually belong to one or several of the global dive organisations. The biggest ones are PADI and SSI. Look for signs like “Five Star Dive Centre” or “Career Development Dive Centre” for highest quality. Small operators can be a good choice, if there is a good match of chemistry between you and the dive shop owner. Small companies are often also more flexible with special needs. The downside could be lack of resources and more hassle because smaller operators use shares boats, rent the equipment from other companies, do not have their own compressors to fill the tanks etc.

3. Check the equipment, boats and logistics

If you are looking forward to use rental equipment, ask to see the gear before making a decision. Diving is much safer and much more fun when the equipment is in good condition, well serviced and well maintained. Look especially at the BCD’s, wetsuits and regulators. BCD and wetsuit should fit you tightly. Be reasonable. There might be some wear and tear but they should not smell bad or be torn apart. Check the mouthpiece of the regulator. there should be no pieces bitten off. Ask about the boats and the overall logistics. How long does it take to get from the dive shop to the boat? Or is there a pickup from your hotel? How long is the boat ride to the dive site? How big is the boat? Is it a shared boat or is only for one dive shop to use? What do you need to bring with you? Is lunch, drinks etc included in the price?

4. Ask about the dives

What is the maximum dive time? some dive shops limit the dive time to 45 or 60 minutes, some let you dive your tank to 50 bar no matter how long it takes. How big are the groups? A nice group size is four divers per divemaster. In some shops, especially in the high season the group size can be much higher, up to 8 -10 people. How are the divers divided to groups? In bigger shops the custom is to have the divers in different groups, based on their certification level such as Open water, Advanced and professionals. This guarantees that everyone is diving with people who are on the same level. Ask about the dive sites. What’s there to see? Are there strong currents, how is the visibility and water temperature?

5 Talk with people

Oceans 5 dive resort

Talk with the people that you are going to dive with. If you get along with them on the dry, there is a good chance that diving will also be much fun! Language is a big issue. Do you share the same language on a level that you can communicate with? A lot of dive shops target certain language groups. English is the most common language in dive shops, but there are also dive shops who specialize in French, Italian, German, Russian, etc customers. If you want to dive with your own language, look around. Dive instructors come mostly from western countries and increasingly also from Asia. You should be able to find a dive school that has people who can teach in your own language.

This blogpost is about 5 tips how to choose a diveshop for your dive holiday. I hope you enjoyed this article. Please feel free to share it with your friends if you feel that this could be useful for them!

Reef cleanup at the Gili Islands

Oceans 5 dive resort in Gili Air Indonesia

Reef cleanup…why? The underwater world is a magical place, where fish and other strange creatures live among beautiful corals, in the shades of light that shines in from the surface. The scenery has not changed much in the last millions of years. Unfortunately, the trace of human hand starts to be more and more visible under water.

How to reduce the human impact in the oceans is a big question. Divers have one efficient way to act on behalf of the oceans. By doing reef cleanups they directly reduce the amount of waste, and at the same time influence other people to be more concerned about their waste management.

Here at Oceans 5 dive resort we frequently organise reef cleanups. The cleanups are free for our customers and students. All divers must be certified as advanced open water or higher. The events are supervised by Oceans 5 ‘s divemasters or instructors.

Mieke Bruvnseels, Divemaster candidate at Oceans 5 dive resort

Mieke Bruvnseels, Divemaster candidate at Oceans 5 dive resort

Mieke Bruvnseels, a divemaster candidate at Oceans 5 is organising the reef cleanup for next week. “It is my way to contribute to Gili Air and the Ocean. I love diving at Gili Air. I have been staying here now for more than two months doing my Divemaster course. Diving here is fantastic” she says, and continues: ” Organising a reef cleanup is also a great challenge to me as a dive professional. Being responsible managing a team is a great experience that helps me to achieve my professional goals. Its like guiding a fun dive but with a real mission.”

Reef cleanups are performed in the house reef, just outside Oceans 5’s dive shop at Gili Air. The event starts around 5 PM, after the harbour is closed and boats are not coming in anymore. For divers the reef cleanup has many benefits. “I like to dive in clean waters” says Mieke. “I also believe that when people see what we do they might also start to think about it and throw less garbage in the ocean”. Divers also have a great possibility to learn to control their buoyancy in real life situation working near the bottom while handling heavy garbage bags.

Before going into the water it is time for a dive briefing. The participants are divided into buddy teams. Each team consists of 2 – 5 divers. Every team is then responsible of one section of the house reef. One diver in every team acts as team leader, supervising the team from above, holding up an SMB to warn boats about the divers below and assisting his team with garbage bags. Dive time is limited to 45 minutes, and every diver is equipped with protective gloves. Divers are briefed not to pick up items which already have coral growing in them and to be careful with any animals that might live inside the garbage.

“By far the majority of waste that is picked up from the reef is plastic in form of bottles, candy wrappers, diapers etc etc. But we also find good stuff. We have found money, shoes and even diving equipment!” says Mieke. “Last week a group of 5 people brought up seven full bags of garbage. This week it’s going to be even more! she says with a grin on her face.

Please contact us for more information about diving at Gili’s and possibilities to join our reef cleanup events!

How to start Scuba diving?

How to start Scuba diving? In this blogpost we explain what Scuba diving is, how to get started and most importantly why start to dive!

Diving around the Gili Islands with IDC dive resort Oceans 5 Gili Air Indonesia

Underwater world is full of miracles; Green turtle at Gili Islands!

Diving is a way for people to explore a new world, to experience a new dimension. Instead of just being able to go left and right, you now can also go up and down. The underwater world is three dimensional! When diving, you feel the sensation of being weightless. To move from one place to another you need very little effort. Surrounded by colourful fishes and corals you can observe a beautiful new world. Many people say that it feels like flying!

Oceans 5 dive resort

Unus and Sur, Divemasters at Oceans5 pic (c) Nayoung Kim 2015

Diving has many sides. Some people like the social aspect. You meet new interesting people from all around the world with a common interest, the passion for diving. For others it is the peaceful easy feeling you get under water, when no one can talk to you and your actions are limited to breathing and watching. Some people like to dive to shipwrecks, others enjoy diving in icy waters with heavy protection dry suits. Some like the big fish; sharks, mantas and bumpheads. Others spend there dive trying to find nudies, small funny species of marine life from sandy bottom or between seaweeds.

What is Scuba diving?

Scuba diving is a form of activity sport that allows you to stay under water for a much longer time than it would be possible with holding your breath. It is also called as “recreational diving” to separate it from technical diving and professional diving. A normal dive lasts approximately 30 to 60 minutes.


Ocean 5’s dive instructor Manon pic (c) Nayoung Kim 2015

With modern equipment and appropriate certification Scuba diving is a safe and fun form of activity. During the dive the diver breaths compressed air from a cylinder that is attached to his back with a vest called “Buoyancy Control Device”. BCD also helps the diver to adjust his buoyancy when under water and, most importantly, helps the diver to stay afloat when on the surface. Air is delivered from the cylinder with a regulator that adjusts the pressure of the air suitable for breathing. Wetsuit, mask, fins and weight belt are other equipment needed in Scuba diving. Recreational diving is also called “no decompression limit diving”. This simply means that all dives are done in a manner that, in case of emergency, the diver can always safely reach the surface. The maximum depth limits for certified divers is 18 meters. This can be extended with further training to 30 and even to 40 meters, which is the absolute maximum limit for recreational diving. All serious Scuba dive schools are organised under one or several dive organisations. PADI is the oldest and largest organisation. SSI, CMAS and RAID are other well known organisations. These organisations develop and maintain certification systems that teach the divers the necessary skills and guarantees that divers are capable of diving within the limits of their certification.

How to start Scuba diving?

DSD, or Discover Scuba Diving, is the most common first step into scuba diving. With DSD program it is possible for anyone to immediately experience the sensation of breathing under water, being weightless and being part of the under water world. In DSD program a dive instructor takes an inexperienced person first into swimming pool to get him familiar with the equipment and then into the ocean for a real dive. During the dive the instructor is always within reach, taking care of the safety and comfort of the diver. Maximum depth of a DSD dive is 12 meters. The purpose of DSD is to deliver the experience of scuba diving, it is not a certification. Please read more about the DSD program from Oceans5 Dive resort’s homepage.

Oceans 5 Dive resort

open water course in Oceans 5’s pool

The first certification level is open Water diver. Open water certification is gained by participating in a 2-4 day course, where all the necessary skills and knowledge are taught in a practical and fun way. The course contains pool sessions where skills are practised, and 4 real dives in the ocean where the skills are put effectively in use. Usually the course is done in small groups which makes it an excellent way to learn how to dive. After the course the diver is certified to dive into a depth of 18 meters together with another certified diver. Please read more about the Open water course from Oceans5 Dive resort’s homepage. Diving takes us to a new environment and opens the door for unbelievable new experiences. To start to dive takes a little bit of effort, but believe me, it is worth it. Once you get your head under the water the payback is immediate: weightlessness, sense of flying, beautiful scenery, fishes, corals… Diving is for everyone. There are over 40 million certified divers in the world, and that number is rapidly growing. Would you like to be one of us? Contact us for more information!

Stay longer, go deeper

Why use Nitrox, to whom is it most beneficial, how does it work, and how could you get Nitrox certified? These are the questions we are going to look into this blog post of Oceans 5 dive resort.

PADI Nitrox Course Gili Islands with IDC Dive Resort Oceans 5 Gili Air Indonesia

PADI Nitrox Course Gili Islands with IDC Dive Resort Oceans 5 Gili Air Indonesia

Ever wondered why some divers use different kind of tanks with green and yellow decals on them? That´s Nitrox, or Enriched air as it is also called.

The advantage of diving with Nitrox is very simple. When you breath Nitrox the amount of Nitrogen dissolving into your body is reduced, and therefore you get more bottom time on deeper depths. Not only does this add more minutes to your dives, but it also adds a significant safetymargin against diving related injuries such as decompression sickness or illness.

Nitrox does not reduce the amount of air you need on a dive. Nitrox is most beneficial for divers who are relatively good with their air consumption. A 45 minute dive with lower than 15 meter average depth is a rule of thumb that you can measure your own air consumption against. The difference in bottom time is significant. With 32% Nitrox the bottom time at 30 meters is 28 minutes which is 11 minutes more than when diving with normal air.

Nitrox diving with PADI IDC Divie resoert Oceans 5 Gili Air in Indonesia

Nitrox diving and sidemount diving a perfect combination around the Gilis

Another situation when Nitrox is beneficial is when you do a lot of repetitive dives in a short period of time. For instance, if you are on a liveboard for three days, doing three to four dives a day the nitrogen levels in your body start to rise to very high. Diving with Nitrox would dramatically reduce the risk of decompression sickness. This is also the reason why professional divers use Nitrox on every dive, if it is available.

How doest it work? From the normal scuba tanks we breathe compressed air which contains 21% Oxygen and 79% Nitrogen. Our body needs the Oxygen but not the Nitrogen. On surface this is not a problem as Nitrogen is disappearing when we exhale. Situation changes when our body is under pressure. Nitrogen starts to dissolve into our body. When the amount of nitrogen increases too much, or, when we ascend from the dive too fast, nitrogen starts to form dangerous bubbles in our body. You can find more information about diving related hazards from here.

Nitrox is also called Enriched Air. In Nitrox the amount of Oxygen is raised to 21% – 40% to reduce the amount of nitrogen. But, the benefits come with a price. Oxygen comes toxic under pressure, so the amount of Oxygen in the Nitrox mix affects the maximum depth of the dive. With 32% Nitrox the maximum depth is 32,4 meters. This is why diving with Nitrox is not allowed without a certification. Diving with Nitrox requires the diver to personally analyse, mark and log his tanks, use a dive computer and respect the depth limits of the mix.

How to get Nitrox certified? Nitrox courses are available for all divers who are certified as Open Water Divers or higher. Here at Oceans 5 dive resort Nitrox course can be done as a dry course without dives, or as a wet course, with two dives. A very good option is also to do the Nitrox course directly as a part of your advanced course. This would mean that you do all your course dives with Nitrox and at the end of the course you are directly certified also to use Nitrox. The course itself contains a small amount of theory, hands on introduction to tank analysis, logging and marking, and diving with Nitrox. The theory part can also be made via e-learning modules, so you dont need to spend precious holidaytime.

With Nitrox you stay in the water longer and go deeper. Adding an extra safety margin is also a good thing. Why not get Nitrox certified on your next dive holiday?
