Explore Australia’s best dive sites

Home to the most famous dive destination on the planet, the Great Barrier Reef, Australia offers unsurpassed and endless dive opportunities. Though the colorful, vibrant, life-filled coral reefs of the Coral Sea are what draw divers here in droves every year, this entire continent/country/island nation is surrounded by water on all sides, creating unending diving possibilities. After diving to your heart’s content on the Great Barrier Reef of Queensland, head to Western Australia to dive alongside whale sharks and manta rays. Australia’s north coast is home to the famous dugong and the rare flatback sea turtle. For a completely different dive experience, head south to the Great Australian Bight, an incredibly biodiverse region filled with immense kelp forests teeming with life.

Discover the World’s Most Fascinating Aquatic Life

Aquatic life under our oceans, lakes, rivers, and streams is amazing! From microscopic zooplankton to the largest animal on earth, the blue whale, underwater life comes in all possible shapes and sizes. With 71% of the earth being covered with water, it is no wonder we are so fascinated with what lies beneath the surface. In fact, scientists estimate that there are nearly 1 million different species of aquatic animals. Freshwater ecosystems are home mainly to fish, invertebrates, and reptiles, whereas the ocean contains a wide array of marine life including fish, mollusks, crustaceans, reptiles, sharks, and marine mammals like whales, dolphins, seals, and manatees.

Sea Lion

Sea lions are pinnipeds that are easily recognizable by their external ear flaps, cute, pointy nose, long, puffed up chest, and their ability to walk on all fours. Some of the more popular sea lion species are the California sea lion and the Steller sea lion. These fast, agile swimmers can reach up to 30 knots underwater and are very curious about the world around them. In fact, sea lions are not afraid of scuba divers in the least and have been known to buzz right around a group of divers, blow bubbles at them, and even chewing on their snorkels and fins.

Dugong

A close relative to the manatee, dugongs are thought by some to be the motivation of seafaring tales of mermaids with their shapely bodies and fluked tails. In fact, they belong to the classification order Sirenia. Dugongs are the only strictly herbivorous marine mammals in the world and can be found all throughout the southern hemisphere, encompassing 40 countries and territories within the Indian and Pacific Oceans.

Great White Shark

With females able to grow up to 7 meters long, the great white shark is the largest predatory fish on earth. It owes its name to its light, almost white, belly color, making it almost invisible to prey looking up from the seafloor. It’s body is similar in construction to a torpedo, making them very good, fast swimmers. In fact, they can reach speeds of up to 25 km/h and, like whales, have the ability to launch their entire body out of the water. Not many species prey on great whites, but if it is attacked, it can rolls its eyes inward for protection. Their eyes can absorb weak light, allowing them to see better in twilight than a cat.

Hawksbill Turtle

Often times considered the most beautiful of all sea turtle species with it’s mottled, colorful shell, the hawksbill sea turtle is one of the smaller species. These graceful creatures are the most tropical of all the turtles and can be found mainly on coral reefs throughout the warmest areas of the world’s oceans. They use their narrow, pointed beak (hence their name) to eat an omnivorous diet, feeding on sponges, sea anemones, and jellyfish.
