Busselton Jetty
Why you’ll love it: Exploring an unusual combination of marine life and man-made structures

Stretching 1.8km (1.1mi) into the Indian Ocean from the coast of the Margaret River region, Busselton Jetty is a spectacular site to behold in itself, but even greater treasures lie beneath its surface. Since the jetty’s construction in 1865, submerged timber pylons have become home to a vibrant array of marine life, with over 300 species now living in the accidental artificial reef. Large underwater sculptures at the end of the jetty were strategically added to provide even more homes for wildlife and an exciting sight for divers to witness in their explorations.

Each piece is designed to highlight the critical need for conservation to protect the delicate ecosystems of the Great Barrier Reef. Climb aboard a tour boat and head out to explore the artists and scientists sculpted within the Coral Greenhouse, or the eerie scattering of Ocean Sentinels.

Why you’ll love it: Diving among coral-covered shipwrecks

In addition to the Museum of Underwater Art, Townsville is also the perfect base for an exciting dive out to the wreck of Steam Ship Yongala. The ship, which sank during a cyclone in 1911, lies mostly intact 14-28m (46-92ft) below the surface. It was found in 1958, and has attracted a wealth of marine life in its 100 years underwater, including vivid soft corals and a population of olive sea snakes. You can book a day trip with Yongala Dive to explore the remains, or take a three-day liveaboard trip with Adrenalin Snorkel and Dive.

Why you’ll love it: Drift-diving your way around an exclusive site

Rowley Shoals is a group of three ring-shaped reefs located about 300km (186mi) off the coast of Western Australia, which make for an incredible exclusive dive experience. The reefs are only accessible for a short time around October, which means you’ll be one of few who have the privilege to experience them. The vibrant formations are famous for their strong tidal flows – creating exhilarating drift dives – and are home to many large species of fish. Head to Broome and charter a luxe liveaboard cruise to experience it for yourself.

Here, you can explore caves lined with rocky columns and reefs that hold deep-sea species of Ballina angelfish, usually only found at depths of over 100m (328ft).
