Ribbon Number Seven Reef - Great Barrier Reef

Ribbon Number One. Now, this is a spot we’ve spent some serious time at, and for good reason. It’s not just another patch of coral; this place has a personality. We love dropping in on the northern end, where the reef edge slopes gently before plunging into deeper water. You get a real feel for the scale of the Great Barrier Reef here. Keep an eye out for the Pacific Half-and-half Chromis, those little flashes of blue and yellow are everywhere, a constant, shimmering cloud that almost tickles your mask. The corals are something else, too – big heads of Wrinkle Coral and Cauliflower Coral, and those sprawling Staghorn thickets. It feels ancient. We've often seen Black Marlin cruising the deeper edge, a dark silhouette against the blue, which is always a thrill. It's a dive that rewards slow exploration, letting the currents carry you past walls dotted with Orange-lined Triggerfish. This one really suits divers who appreciate a healthy, expansive reef system over specific megafauna encounters, though the marlin are a nice bonus. Go in the morning; the light really brings out the colours of the corals.
