Everything you need to know about this dive site.
Dive Site Overview
Milne Bay diving, with its profound historical context including World War Two wrecks like the Black Jack B17F Flying Fortress bomber, has firmly established Papua New Guinea as a premier dive destination. Sponge Heaven, a wall dive, contributes significantly to this reputation, presenting a dramatic underwater landscape that plunges from a shallow shelf just 1 m (3 ft) below the surface to depths exceeding 100 m (350 ft).
An expansive wall, it's extensively honeycombed with small caves, creating intricate habitats. Within these natural shelters and along the exposed rock faces, a rich variety of sponges thrive, lending the site its descriptive name. Divers can anticipate mild currents, making navigation manageable along the wall.
Particularly notable is the diverse and colorful sponge fauna, which forms a vivid backdrop for numerous nudibranchs. Its accessibility and character also make it a favored location for night dives, where nocturnal marine life emerges against the illuminated sponge formations.

Best Time to Dive
Optimal conditions for Sponge Heaven diving typically span January through April and November through December, when dive scores are consistently 'Excellent'. During these months, air temperatures are comfortably warm, ranging from approximately 27.5°C to 28°C (82°F), and wave heights remain low, around 0.3 m (1.0 ft), contributing to calmer seas. Rainfall is also generally lower, enhancing surface conditions. A 'Good' season from May to October sees air temperatures cool slightly to 25.5-27°C (78-81°F), with increased wave heights of 0.5-0.8 m (1.6-2.6 ft) and higher wind speeds; diving remains feasible then. Water temperature, however, can be consistently cool, hovering around 22-23°C (72-74°F) year-round, regardless of the season's dive rating, so preparation for cooler conditions is advisable.

Dive Experience & Conditions
Current dynamics at Sponge Heaven are generally slight to mild, typically allowing for relaxed exploration of its vertical terrain. A sheer wall descends from a shallow shelf, inviting divers to trace its contours. Many small caves and overhangs can be investigated. Water visibility in this area is commonly observed between 15-30 m (49-98 ft), providing clear views of extensive sponge growths and other macro life. Divers should be prepared for cooler water temperatures, consistently reported around 22-23°C (72-74°F); some divers have noted feeling cold after 45 minutes, even with a 3 mm wetsuit, hood, and gloves. On occasion, stinging salps may be present in the water, though such conditions are not consistently reported and can dissipate abruptly. Collectively, these elements shape a dive experience that rewards attentive exploration of a richly textured wall.
Dive Difficulty & Safety Guidelines
When diving Sponge Heaven, understanding the local context and maintaining situational awareness are key for diver safety. As a boat-accessible site, it generally requires diving with a guide, although unguided shore dives on house reefs are sometimes an option. While conditions present mild currents and manageable conditions for most certified divers, a wall's significant depth beyond recreational limits means careful depth management is essential. It's important for divers to be aware that the broader area surrounding Tawali resort has experienced security incidents, including armed robberies, though local residents are described as welcoming. Divers should confirm current security advisories with their dive operator and resort management. Always dive within your training and comfort levels, especially when exploring deeper sections or considering night dives, which, while possible at this site, often incur higher costs for boat-accessible locations.
