Roe Reef is a beginner-friendly boat dive off Western Australia that punches well above its weight for marine life encounters. Depths run from 8 to 18 metres, and visibility frequently reaches 25 metres, making it easy to get your bearings underwater. Currents can run moderate to strong, so stick close to your guide and plan your dive with the flow. Keep an eye on the bottom for wobbegong sharks resting flat against the reef, and check crevices for crayfish and porcupinefish. Buffalo bream and snapper move through in loose groups, while lucky divers occasionally spot dolphins or sea lions passing by. The rare leafy sea dragon rounds out an impressive species list for a single site.

Book a guided tour rather than a self-guided charter if you are newer to diving, as the moderate current can strengthen without much warning and a local guide will know the best slack-tide windows. Keep a sharp eye along sandy patches at the reef edges, which is where wobbegong sharks and leafy sea dragons tend to sit still and blend in.
The site is approximately 2km north-east of Rottnest Island and is accessed via boat, typically from Fremantle. The boat trip from Perth/Fremantle is about 40 minutes.
The area can be exposed to wind and swell. It is best dived in the morning when winds are low (under 15 knots) and swell is less than 1m.
