The Ribbon Reefs extend 80 kilometres along the outer Great Barrier Reef, featuring a diverse topography of walls, channels, and reef structures. Depths range from 5 to 40 metres, with an average of 20 metres. These sites are accessed exclusively by boat, typically via liveaboard or day charter from Port Douglas. Divers encounter moderate currents, particularly during incoming tides, which facilitate drift dives at locations such as Dynamite Pass and Cod Hole. Visibility varies from 0 to 40 metres. Water temperatures remain between 25 and 28C throughout the year. Due to the presence of deep water, strong currents, and sharp coral, this area is best suited for intermediate divers.
