Jeff’s Edge - Coral Sea

Matavera Point holds a special spot for us, a place where Rarotonga really shows off its stronger currents and bigger fish. We love how this reef plateau, sitting around 20 metres, just pushes out into the blue, creating a visible corner where the water masses collide. Drop down, and you’re on a proper vertical wall, not just a slope, that just keeps going. It’s where you’ll often feel a decent push, which means the pelagics often cruise past – we’ve seen eagle rays ghosting by more than once here. The schools of fusiliers and damsels on the wall are so thick they sometimes make the light ripple, and we often spot several types of wrasse darting in and out, like the colourful pearl-spotted and dusky wrasse. Keep an eye out for Isabel’s hermit crabs scuttling around, and the striking Achilles tang. This spot is definitely one for the more experienced diver who appreciates a bit of current and the potential for larger visitors. The visibility here is usually excellent, often pushing 35 metres, so you get a great sense of the wall’s scale.
