The Great Barrier Reef in Australia boasts one of the richest marine environments in the world, with more than 1500 species of fish and 360 species of hard coral. In the outer reefs, you may encounter six different species of sea turtles and several shark species, such as grey reef sharks, whale sharks, silky sharks, and even hammerheads or tiger sharks. Manta rays are usually seen in the southern sections of the Reef, and dugongs can occasionally be found in the shallow seagrass beds.
While diving in the Great Barrier Reef, you’ll find underwater environments to suit every interest. Coral gardens, pinnacles, bommies, channels, and caverns make up the majority of sites, but seagrass beds, wrecks, and pelagic cleaning stations can also be found. Liveaboard divers will want to stop by Cod Hole, where the famously friendly potato cod greet divers, and the Ribbon Reefs is a must-visit area due to its amazing marine biodiversity.
The Great Barrier Reef is the largest living thing on Earth and one of the 7 natural wonders of the world. While you may be able to sample the inner reefs on a day trip from the mainland, the outer reefs offer a more pristine experience combined with greater biodiversity, healthier corals, and fewer divers. These remote sections of the Reef are only accessible by liveaboard.
Dive safaris headed for the Great Barrier Reef usually depart from Cairns, Queensland, in northwest Australia. These liveaboard trips typically take 2 to 5 days, although some operators offer longer 8-day itineraries.
The best time to dive in the Great Barrier Reef is from June to December. During these months, several elements align to create great diving. From June to November, the water temperature drops, attracting pelagic species such as manta rays, whale sharks, and minke whales. You’ll also enjoy excellent visibility, reaching up to an incredible 200 feet (60 meters) in the outer reefs.
It’s also important to note that the Great Barrier Reef is one of the best liveaboard destinations for beginners. Some divers even complete their Open Water course on a liveaboard in Australia. A lack of current, comfortable water temperatures and excellent visibility make the Great Barrier Reef ideal for learning.
