The Cod Hole is a prominent site on the outer Ribbon Reefs, featuring a sloping reef wall that descends from 3 to 40 metres. The topography is defined by hard corals, sea fans, and bommies. Divers access this site exclusively by boat, with conditions often supporting drift dives due to moderate currents. Visibility typically ranges from 15 to 40 metres. The site is suitable for intermediate divers who should remain aware of potential current changes and follow guide protocols. Water temperatures remain between 25 and 28C throughout the year. Protective suits are recommended to mitigate risks from jellyfish, particularly during the stinger season from November to May.

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.

Rouge is a Ribbon Reef site offering a diverse topography that transitions from a shallow reef slope into a deeper drop-off. Divers can explore depths ranging from 5 to 40 metres, with an average depth of 18 metres. This site is strictly a boat dive, suitable for intermediate divers comfortable with drift diving and managing variable currents. Visibility typically ranges between 10 and 40 metres. Due to the potential for strong currents and down currents near the drop-off, solid buoyancy control is required. The site is accessible throughout most of the year, excluding July and August, and supports night diving.

Lighthouse Bommie is a standalone pinnacle rising from deeper water to within 5 metres of the surface. This site is suited to intermediate divers who can manage strong currents. The structure features colourful corals from the top to the base, with anemones and invertebrates inhabiting the lower nooks and ledges. Visibility varies significantly, ranging from 7 to 30 metres. Divers should be prepared for strong currents and maintain awareness of their position relative to the boat. Hazards include jellyfish and sharks.
