Dive Site: Lizard Island

About Lizard Island

Lizard Island serves as a key destination in the remote Far Northern Great Barrier Reef, offering access to some of the planet's most pristine and least explored underwater environments. Located far from typical tourist routes, this area is characterized by vibrant, healthy coral systems thriving due to strong oceanic currents and exceptional water clarity. The diverse underwater landscape includes towering oceanic walls, isolated pinnacles, flourishing coral gardens, deep canyons, and hidden caves, providing a truly expeditionary diving experience. Diving here reveals a rich biodiversity distinct from other GBR regions. Expect encounters with a variety of pelagic species, numerous reef fish, and significant macro life. The area is particularly known for large numbers of green sea turtles during their nesting season. Access to these remote dive sites, including the renowned Ribbon Reefs, is primarily via multi-day liveaboard trips departing from Cairns or Port Douglas. Divers should be prepared for varying conditions, including potentially strong currents, which contribute to the health of the coral but also require a higher level of experience. The island itself, though a remote landing point, offers a few land-based activities like hiking, but its primary significance for divers is its proximity to the untouched outer reefs.

Conditions & Currents

Currents around Lizard Island and the Far North Great Barrier Reef are common and can be strong, especially at exposed sites like Tijou Reef and Raine Island. These powerful oceanic currents play a crucial role in maintaining the reef's health and vibrant coral cover, but they also demand confident and experienced divers. Tidal influences can dictate current strength and direction, necessitating careful dive planning. Entry and exit are typically from liveaboard tenders, requiring awareness of current patterns. Visibility is generally excellent, ranging from 10 to 25 meters, and can be exceptional. While thermoclines are not prominently mentioned as a significant issue, water temperatures fluctuate seasonally. Divers should be prepared for drift dives and be proficient in current navigation and safety procedures.

Dive profile & how the dive runs

Diving around Lizard Island typically involves liveaboard operations accessing the surrounding Ribbon Reefs and outer coral systems. Entry is usually via tender boat, often with a negative entry to descend quickly in areas with currents. Dives explore steep oceanic walls adorned with gorgonians and soft corals, isolated pinnacles, or vibrant coral gardens. Depths can range from shallow reef tops at 12 meters to over 40 meters on deeper wall dives. Routes are often drift dives, allowing divers to be carried by currents along the reef, observing pelagic schools and reef sharks. Specific sites like Cod Hole feature interactions with large Potato Cod at the seafloor. Turn points are usually determined by air consumption or bottom time, with ascents along the reef face. Safety stops are performed in the shallower reef areas, often with visual reference, before surfacing for pickup by the tender.

Underwater photography

The remote and pristine nature of the Far North GBR around Lizard Island offers exceptional underwater photography opportunities. Wide-angle lenses are essential for capturing the expansive coral formations, steep walls, and pelagic schools like barracuda and reef sharks. Due to the generally excellent visibility and strong currents, securing your position to compose shots while maintaining good buoyancy is crucial. Macro lenses are also highly rewarding for documenting the diverse and dense macro biodiversity, including nudibranchs, shrimps, and pipefish, often found tucked into the reef structure. External strobes are recommended to bring out the true colors of the corals and marine life, especially at deeper sections or in overhead environments like caves. Be respectful of marine life, particularly the large Potato Cod at Cod Hole, maintaining a comfortable distance while photographing.

Getting there & logistics

Access to the remote Far Northern Great Barrier Reef and Lizard Island is primarily through multi-day liveaboard trips, as it is hundreds of kilometers from populated areas and not reachable by day boats from Cairns. Liveaboards typically depart from Cairns or Port Douglas. These trips usually last at least three or four days, with some expeditions to more distant sites like Osprey Reef requiring a week. Lizard Island itself has an airstrip, allowing for transfers to and from liveaboard operations. Marine Park fees are typically included in liveaboard packages. Planning ahead is essential, especially during peak seasons, as availability on these specialized trips can be limited.

Safety & environment

Diving near Lizard Island in the Far North GBR requires a strong emphasis on diver safety due to the remote nature of the sites and potentially strong currents. Divers should carry adequate insurance covering dive accidents and medical evacuation. The nearest recompression chamber is likely located in Cairns, necessitating a significant evacuation time in case of emergency. Liveaboard operators are equipped with emergency oxygen and first aid, and strict dive protocols are followed. Advanced Open Water certification is strongly recommended, with Deep Diver certification beneficial for some sites. Always dive within your training and comfort limits, pay close attention to dive briefings, and monitor your air consumption and bottom time diligently.
