Dive Site: Ribbon Reef

About Ribbon Reef

The Ribbon Reefs comprise ten elongated, narrow coral structures that form the outer edge of the Great Barrier Reef, stretching between Cooktown and Cape York in northern Queensland, Australia. These remote reefs are situated approximately 50-100 km offshore, making them exclusively accessible via liveaboard trips. Characteristically, the Ribbon Reefs are no wider than 450 meters and generally quite shallow, often rising to within 5 meters of the surface from sandy bottoms typically 15-20 meters deep. The outer walls can drop to significant depths, in places covered by soft coral communities. The northern reefs, particularly Ribbon Reef #9 and #10, are celebrated for the highest quality diving, featuring cleaner oceanic water and exceptional marine life density. Marine biodiversity is remarkable, including resident populations of potato cod at famous sites like Cod Hole, alongside frequent sightings of reef sharks, large pelagics, and abundant macro life. Specific seasonal highlights include dwarf minke whales from June to July and extensive turtle nesting activity from October to March, particularly around Raine Island. Visibility is generally excellent year-round, often ranging from 10 to 25 meters, with potential for up to 35 meters or even 60 meters in the Coral Sea. The diving experience here is considered pristine and adventurous, far removed from typical tourist crowds, making it a staple for liveaboard itineraries seeking an untouched Great Barrier Reef experience.

Conditions & Currents

Diving the Ribbon Reefs involves variable current conditions, ranging from mild in protected areas to strong on exposed reef walls and in passages between reefs. These passages, designed as ship channels, can create excellent drift diving opportunities during specific tidal conditions, necessitating careful planning for entry and exit techniques. While many sites are shallow and beginner-friendly with minimal currents, deeper wall dives and certain locations like Raine Island and Tijou can experience significant water movement, requiring advanced diving skills and good buoyancy control. Visibility is consistently good, ranging from 10 to 25 meters, with potential for up to 35 meters on the northern ribbons due to cleaner oceanic flushing, and rarely up to 60 meters in the Coral Sea. Surface conditions are generally calm year-round, though south-easterly trade winds can be stronger from M

Dive profile & how the dive runs

Typical dives at the Ribbon Reefs often involve descending to a sandy area at around 18-22 meters, as seen at Cod Hole, to observe resident potato cod. From here, divers can explore the surrounding reef structure, which starts at a mere 5 meters and gently slopes down, revealing extensive hard coral fields intertwined with sandy gullies. Sites like Steve's Bommie are pinnacles rising from 28 meters to within 3 meters of the surface, offering a circular route to view diverse macro and schooling fish life across different depth bands. Deeper wall dives, found on the outer edges, may require descents to 40+ meters. Safety stops are typically conducted in the shallower sections of the reef, often among vibrant coral gardens, where plenty of smaller marine life can be observed. Given the potential for currents, particularly in passages between reefs, divers should maintain situational awareness and stay close to their guides.

Underwater photography

Underwater photography at the Ribbon Reefs offers a wide array of subjects, from large pelagics to intricate macro life. For wide-angle shots, especially with the charismatic potato cod at Cod Hole, an 8-15mm lens is ideal; position strobes wide and behind the lens to minimize backscatter from the bright sandy bottom. Mid-range lenses are excellent for capturing schools of barracuda, trevally, and reef sharks. Macro enthusiasts will find abundant opportunities for nudibranchs, pygmy seahorses, pipefish, and anemonefish, particularly at sites like Lighthouse Bommie. Consider shooting wide-angle during midday for natural light and vibrant color saturation, reserving macro dives for earlier mornings or late afternoons when artificial light becomes more crucial. Buoyancy control is paramount to avoid disturbing delicate corals and stirring up sand, especially around subject-rich areas.

Getting there & logistics

Access to the Ribbon Reefs is predominantly via liveaboard cruises, departing from Cairns or Port Douglas. Cairns International Airport (CNS) serves as the primary gateway. These itineraries typically span 3 to 7 days, combining Ribbon Reef sites with the renowned Cod Hole and sometimes extending to Coral Sea destinations like Osprey Reef. Given the remote location, day trips are not feasible for most Ribbon Reef sites. Park fees may apply as it is part of the Great Barrier Reef Marine Park. It's advisable to book well in advance, especially during peak seasons, as liveaboard spaces can be limited.

Safety & environment

Diving at the Ribbon Reefs, due to its remote location, requires adherence to strict safety protocols. The nearest recompression chamber is located in Townsville. Evacuation in case of a medical emergency can be complex and time-consuming, often requiring air transport, so comprehensive dive insurance including emergency evacuation coverage is highly recommended. Site-specific hazards include potentially strong currents, especially in passages, which necessitate proper dive planning and buddy system adherence. Divers should be confident in their skills, particularly for advanced sites, and follow dive guide instructions diligently. Always monitor air consumption and bottom time, and be aware of surrounding marine life, maintaining respectful distances from animals, particularly large groupers and sharks.
