Cherie's Reef, Milne Bay: Drift Diving Gorgonian Gardens

Cherie's Reef is an offshore reef south of East Cape in Milne Bay, best experienced as a drift dive. You enter the water upstream, letting the current carry you along a sloping reef face rather than a vertical wall. This approach allows for a relaxed dive profile, enabling you to focus on the marine life without expending energy fighting the flow. The boat follows your progress, ready to pick you up downstream once the dive is complete.

The topography here is defined by a gradual reef slope, descending to a maximum depth of 30 metres. This slope is densely covered with large gorgonian sea fans, thriving in the nutrient-rich currents that sweep through the area. These formations create a complex, living tapestry, providing both shelter and hunting grounds for a diverse range of reef inhabitants. As you drift, the sheer scale of these gorgonian gardens becomes apparent, stretching out as far as the eye can see.

Among these extensive gorgonian formations, Cherie's Reef is particularly noted for the presence of the Murasela gorgonian, a specific species that hosts the Bargabanti pygmy seahorse (Hippocampus bargibanti). Spotting these minute crustaceans requires a keen eye and a patient approach, as their camouflage is near-perfect, allowing them to blend seamlessly with their coral homes. Finding one is often a highlight, rewarding the effort of a careful search.

Beyond the macro life, the reef slope is alive with large schools of fish, moving in unison with the current. These schools add a dynamic layer of activity and colour to the dive, often surrounding you as you navigate the reef. The abundance of schooling reef fish is a clear indicator of the health and vitality of this ecosystem, making each drift a unique visual experience.

The currents at Cherie's Reef are a defining feature of the dive, ranging from gentle to very strong. This variability means that while it's consistently a drift dive, the pace can shift. Dive operators often choose the protected side of the reef depending on the current direction, sometimes diving the sheltered south side when the current comes from the north. This adaptability ensures a manageable drift while still experiencing the site's full potential.

Visibility at Cherie's Reef is generally good, often extending beyond 20 metres, allowing for clear views of the expansive gorgonian fields and schooling fish. The nutrient-rich waters that fuel the reef's growth also contribute to this clarity, especially during the optimal diving period. This clear water enhances the experience of drifting over the vibrant reef, making it easier to spot both the large schools and the smaller, camouflaged creatures.

In addition to the pygmy seahorses, the reef supports a variety of other invertebrates. Keep an eye out for flatworms, including the distinctive starry-night flatworm and sapphire flatworm, often found on the south side of the reef. These smaller details add another layer of discovery to the dive, complementing the larger formations and fish schools that dominate the landscape. Every section of the reef offers something new to observe, from the smallest flatworm to the largest gorgonian fan.
