Dive-site story
Located on the sheltered side of Flinders Reef off Moreton Island, Alden's Cave is an open cavern and swim-through structure formed by limestone and coral formations. Divers can explore sandy gutters flanked by plate and staghorn corals before penetrating wide rock openings where marine life shelters from the open ocean swell.
Wide cavern swim-throughs sheltering nocturnal fish and resting sharks
Dense hard coral coverage featuring plate, branching, and brain corals
Frequent encounters with green turtles and bull rays along the sandy gutters
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Winter and spring bring the highest underwater visibility and grey nurse shark aggregations, while summer months offer warmer water and leopard shark visits.
