Nudibranch City - Poor Knights Islands

Right Bet gives you that classic Sulawesi wall dive feel, starting with a sheer drop that’s just loaded with corals. As you drift along, it transitions into more of a gentle slope, which we find is often where you spot the smaller, tucked-away creatures. We’ve seen a good number of turtles here, lazily munching on the reef, and it’s a reliable spot for nudibranchs and those tiny shrimp and crabs hiding in the crevices. Keep an eye out into the blue for a passing blacktip. It’s a solid pick for divers who enjoy a relaxed drift and appreciate both the grand scale of a wall and the minute details of the reef.
