Mataking Island
I have watched guests step off the speedboat after an hour on the water and realise the island they booked is actually two. At low tide a white sandbar connects Mataking Besar to Mataking Kecil. The water drops away and you can walk between them. A few hours later the ocean swallows the bridge. Misjudge the tide table and you wait on the small island until the sea gives the path back.

Mataking sits up to forty-three kilometres out from the mainland jetty in Semporna. It occupies the far eastern fringe of the archipelago right on the maritime border. Choosing a resort this far out is a deliberate act. You come here when you want a deep trench on one side and a shallow macro slope on the other.
The two-island geography
Most dive resorts are a single landmass or a water village built on wooden stilts. Mataking is a binary system. The main resort sits on roughly thirty acres of jungle. The second island is completely uninhabited and the sandbar dictates when you can visit it. The water pulls back to reveal a bright white causeway. The ocean on either side shows as two different shades of blue. It looks right on a postcard from the wooden watchtower above the treeline. The ground reality is a firm schedule. If you want the photograph, you watch the clock.
The terrestrial side of the resort caters heavily to people who never put a regulator in their mouths. A peacock sanctuary occupies the interior. A spa sits near the treeline. It offers traditional body masks while the divers spend their mornings on the boats. Guests snorkel the shallows right off the beach. The visibility on the western side often hits twenty metres without anyone needing to start an engine. The security here is heavy and continuous. The Eastern Sabah Security Command maintains an armed presence around the island. Older travel advisories paint a wild frontier. The daily reality is a heavily monitored resort zone.
The underwater post office and the jetty
Twenty years ago the resort scuttled a wooden cargo ship to build a reef, according to The Star. The Mataking 1 measures twelve metres according to The Star and sits upright in the sand. It functions as Malaysia's first underwater post office. A few aggregator sites claim it is the first in the world. Vanuatu holds that title. The mailbox here is bolted securely to the forward wheelhouse. Dive logs put the mailbox between twenty-two and twenty-seven metres deep. The depth changes with the tide.
The postal service operates just like the one on land. Divers buy a waterproof postcard at the surface. They seal it inside a vacuum bag and carry it down the mooring line. You manage your bottom time and your air consumption while you stuff an envelope into a submerged metal box. The dive team clears the box twice a week. They stamp the plastic and hand it over to the national postal network.
The house reef begins at the beach and drops in stages down to fifty metres. The wooden pilings of the resort jetty disrupt the nutrient flow. That structural bottleneck creates a localised ecosystem packed with schooling fish. A resident giant moray eel lives in the shadow of those pilings. It has been reported at up to three metres long and commands the space with total authority. We drop in for an unguided afternoon dive and navigate straight to the wooden pillars. Divers have regularly seen the eel around the pilings. A resident giant barracuda named Charlie patrols the shallows right above the jacks.
Dropping into the Alice Channel
The eastern shoreline is a different ocean. The reef here forms a drop-off into a deep-water trench called the Alice Channel. Sabah Travel Guide puts the seabed beyond one hundred metres. That steep underwater terrain funnels powerful currents against the wall. The water moves hard and unpredictable. It pushes up from the deep and pulls down from the surface. You need flawless buoyancy control to dive it safely.
Dive sites like North Point and D'Wall expose you to serious depth. The deep blue acts as a highway for open-water fish that rarely visit the shallower inner islands. I have watched eagle rays glide past on drift dives here. Grey reef sharks patrol the blue water. Scalloped hammerheads occasionally show up.
North Point features a cleaning station at thirty-five metres. Large predators have been observed here with cleaner wrasses at work. Depth limits your bottom time. At that depth the watching time is short before your dive computer calls you shallower. We ride the current up the wall and let the boat chase our surface markers.
Turtle nesting and the macro slope
The western and southern shores slope gently away from the island. This is the macro territory. The environment here is sheltered from the deep trench currents. Meticulous divers drop below twenty metres to hunt for pygmy seahorses. The guides navigate to the gorgonian fan first and the animal second. The seahorses anchor themselves to the branches and match the pink of their host.
Sites like Coral Garden and Sweetlips Rock are multi-level terraces. Sponges and crinoids cover the hard coral. The nudibranch population changes by the week. An animal the size of your thumb can halt a dive group for ten minutes while the photographers cycle through. Flawless buoyancy is mandatory. You cannot brace against the reef when the reef is alive.
Above the waterline the island serves as a major nesting ground for sea turtles. Green and Hawksbill turtles haul themselves up the beach year-round. Female Greens average nearly a metre in shell length. They dig pits in the sand and lay an average of eighty-seven eggs per clutch. The resident marine biology team relocates the eggs to a protected hatchery to shield them from poaching and beach erosion. The study recorded an average incubation of just over fifty-six days in the hatchery. Hawksbill clutches averaged just over fifty-seven days in the study. Guests can sponsor a nest to fund the conservation work. Hatchling photographs are part of the resort's nest adoption programme.
The reality of the Sipadan run
People look at a map of Sabah and assume every island is a quick boat ride to Sipadan. Mataking sits far out on the eastern edge. The speedboat commute spans eighty minutes across the open waters of the Alice Channel. You feel the distance in your spine if the wind picks up. The transit takes significantly longer than the brief runs from the inner islands.
Access to Sipadan is heavily restricted and the logistics dictate the itinerary. The park authority issues a tightly capped daily pool of permits. Divers and snorkellers draw from that same allocation. The resort receives a small fraction of those permits. Securing one requires a minimum stay of three nights on Mataking. The regulatory guardrails are uncompromising. Your permit grants you three dives for the day since the rule changed in May 2026. Sabah Parks shuts the entire island down every November for ecological recovery.
The long transit makes the Sipadan day a serious commitment. The boat leaves early and returns late. You spend a large part of your morning crossing the channel. I have watched the barracuda vortex above the drop-off. If daily Sipadan trips are your priority, Mabul or Kapalai may fit your plans. Mataking suits a different brief. It fits the family that wants a large private chalet and a spa. It fits the macro photographer who wants an unguided house reef all afternoon. It fits the diver who wants to walk a sandbar at low tide and mail a postcard at twenty metres.
If you base yourself here, you accept the boat ride to the headline park to gain the isolation of the outer edge. Read more about the Sipadan permit system or compare the resort options across the islands. Send us your dates and your diver certifications and we will build the itinerary that fits.
