About Flat Rock
Flat Rock is a Port Macquarie boat reef with a shallow Turtle Cave line and a broader outer edge. The easier section suits relaxed reef cruising, while the site still rewards divers who are comfortable planning around offshore movement and a simple cave feature. Expect mixed fish life, rays, wobbegongs, morays, and seasonal grey nurse shark use, and pick the calmest boat window to keep the dive easy.
