Raine Island - GBR is a remote, liveaboard-only fringing reef around a protected coral cay in the far northern Great Barrier Reef. It is known for extraordinary green turtle gatherings, pristine coral gardens, and outer-reef walls; the island itself is closed to public landing. The dive is expedition-driven and seasonally focused, so planning is about the boat itinerary, protected-zone rules, and open-water conditions as much as the reef itself.
