Explore the underwater world without getting wet

Semi-submarine tours offer one of the most exciting and accessible ways to explore the Great Barrier Reef—no snorkel or swimwear required! From Cairns, you can step aboard these unique vessels and cruise through vibrant coral gardens while staying completely dry. With large viewing windows and live commentary, it’s like entering a real-life aquarium, only better.

These vessels sit just below the water’s surface, giving you eye-level views of marine life as it glides past your window. You might see schools of brightly coloured fish, waving sea fans, giant clams, or even a green sea turtle cruising by. The commentary from experienced reef guides adds fascinating insight into the ecosystem you’re floating through.

Semi-sub tours are perfect for non-swimmers, families with young children, older guests, and anyone who prefers a gentle, seated experience.

The curved windows in the semi-sub create an immersive, panoramic reef experience—great for photography, reef learning, and simply marvelling at the diversity of the underwater world. It’s peaceful, comfortable, and a beautiful way to see the reef up close.
