Depth Note

Strong current
Safety Notes
Follow the crew brief for your assigned mooring, as conditions range from calm coral gardens to drift-style wall dives with stronger tidal flow on the exposed side.

Legal Notes
Great Barrier Reef Marine Park rules apply. Follow operator and marine park instructions, avoid standing on or touching coral, and expect the standard Environmental Management Charge on eligible trips.
Local Intel For Flynn Reef
Community notes to help plan your visit.
Scuba Diving
Flynn suits scuba divers who want flexible site selection, from shallow coral gardens for newer divers to wall, bommie and light-drift routes for more experienced teams.
Freediving
Freedivers can work the shallow bommies and coral gardens on calm days, but boat logistics and changing current keep it more operator-led than self-guided.
Snorkeling
Many Flynn moorings have coral close to the surface, so guided snorkel routes can stay productive without long surface swims when conditions are settled.
