Conditions & Currents
Restorf Island, situated within the sheltered Kimbe Bay, benefits from a generally calm environment, protected from open-ocean conditions by a chain of dormant volcanoes. Currents around the island are typically mild, making it suitable for divers of various experience levels. However, as with many sites in the Bismarck Sea, localized currents can occur and may influence fish behavior, often bringing schooling fish to life. Visibility remains consistently good to excellent, often ranging from 20 to 50 meters, due to the deep open waters of the Bismarck Sea that feed into the bay. Water temperatures are warm, averaging between 27-30°C, allowing for comfortable long dives. Entry and exit are usually straightforward, often from a tender boat, and divers can focus on buoyancy control to protect the abundant macro life and soft corals.

commonDive profile & how the dive runs
A typical dive at Restorf Island often begins with a descent near the reef slope, where divers can immediately appreciate the vibrant hard and soft corals. The dive master will guide the group along the varied topography, which transitions from coral-covered walls to areas with silty bottoms, ideal for macro life spotting. Divers can explore depths ranging from 5 to 30 meters, focusing on the abundant critter population in shallower areas and the larger sponges at moderate depths. A common route might involve a gentle drift along the reef, allowing ample time to examine crevices and overhangs for hidden creatures. The dive concludes with a gradual ascent, allowing for a safety stop over the shallower reef top, where schools of small reef fish often congregate, before returning to the surface for pickup.
Underwater photography
Restorf Island is a haven for both macro and wide-angle underwater photography. For macro enthusiasts, a 60mm or 100mm lens is highly recommended to capture the intricate details of blue ribbon eels, harlequin ghost pipefish, and various nudibranchs found in the critter-rich areas. Patience and a keen eye are essential when searching for the well-camouflaged devil scorpionfish or twin spot gobies. Wide-angle photographers will find excellent opportunities to frame the massive sponges and healthy soft coral formations, particularly with ambient light in the clear waters. Strong strobes are beneficial for bringing out the vibrant colors of the corals and for illuminating subjects in shaded areas. Maintaining excellent buoyancy is crucial to avoid disturbing the delicate silty bottom and its resident critters, ensuring clear shots and preserving the pristine environment.

Getting there & logistics
Access to Restorf Island primarily involves liveaboard trips departing from Walindi Plantation Resort in Kimbe Bay, New Britain. The nearest international airport is Port Moresby (POM) on mainland New Guinea, requiring a domestic transfer to Hoskins Airport (HKN) near Kimbe. Liveaboards typically offer itineraries ranging from 7 to 10 nights, combining dives within Kimbe Bay with excursions to more remote sites like the Witu Islands or Fathers Reef. Day trips to Restorf Island are also offered by local resorts. Currently, Papua New Guinea does not have specific national park fees for divers, but liveaboard and resort packages usually include all necessary permits and local fees. Travel to this remote region is an adventure, so allow ample time for connections.
Safety & environment
Diving in Papua New Guinea, including Restorf Island, requires adherence to standard safety protocols and comprehensive dive insurance. While Kimbe Bay is generally sheltered, remote locations mean that emergency medical facilities, including recompression chambers, are not immediately available. The nearest recompression chamber is likely in Port Moresby, necessitating complex and potentially lengthy evacuation procedures in case of a serious dive accident. It is imperative to have robust dive accident insurance that covers emergency medical treatment and evacuation. Divers should always dive within their certification limits, maintain excellent buoyancy control to protect fragile corals, and follow the guidance of experienced local dive guides who are familiar with the specific conditions and marine life of Restorf Island.

Why dive Restorf Island from a liveaboard?
Restorf Island is one of Papua New Guinea's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
