Fitzroy Reef Lagoon sits within the Capricorn Bunker Group and offers beginners a gentle introduction to reef diving. The water is shallow, running from 7 to 10 metres, and visibility is genuinely impressive at 15 to 30 metres, so you can see clearly across the reef even without experience reading conditions. Currents vary, so check with your boat operator before entry. The reef supports a healthy mix of rays, including manta, bull, and eagle rays, alongside three species of turtle: loggerhead, green, and hawksbill. White tip and black tip reef sharks, dolphins, and angelfish round out what you can reasonably expect to encounter. Give marine life space and avoid touching anything.
