Busselton Jetty Underwater Observatory Experience

Busselton Jetty at Geographe Bay in Western Australia holds a double marvel: it is not only the longest wooden jetty in the Southern Hemisphere, but also home to one of only six underwater observatories in the world. Take a solar‑powered train across the sea, then dive beneath the waves to explore the reef—a feast of coast and deep sea awaits you.

The red Stocker Preston Express train is your first stop—solar and electric powered, eco‑friendly and unique. With 90 seats and departures every hour, the train glides slowly across the 1.8‑kilometre jetty. The sea breeze carries the scent of the ocean to your face, and the 360‑degree panoramic view seamlessly blends the azure of Geographe Bay with the horizon, while dolphins leaping out of the water may come into view at any moment.

At the end of the jetty, the real surprise begins. Follow a professional guide down the spiral staircase and dive 8 metres underwater to the observatory. Through 11 viewing windows, you are instantly transported into an "underwater forest"—on the largest artificial coral reef in Australia, formed by the jetty's pilings, over 300 marine species make their home. Colourful corals, lively fish, and peculiar sponges fill your view. A 40‑minute guided tour lets you uncover the stories of this underwater wonderland.

A single day pass covers a full day of fun: take the train and explore underwater during the day, then in the evening stroll along the jetty, go fishing, or rent a bike to feel the wind. Operating hours are flexible—10am to 5pm in summer and 10am to 4pm in winter—to fit your itinerary. Tickets are available at the visitor centre, where you can also grab sunscreen, fishing gear, and snacks to meet your every need.

This is a paradise for all ages: seniors can rest on the jetty and enjoy the views, children cheer at the fish underwater, and young visitors are busy capturing the double spectacle of the "train over the sea" and "underwater wonders" with their cameras. Whether it is a family trip or a solo adventure, you will find joy in the blend of nature and history.

Don't let your Western Australia trip have regrets—head to Busselton Jetty for an adventure that goes "up to the sky and down to the sea." Ride the solar‑powered train to enjoy coastal vistas, dive into the underwater observatory to explore the coral reef, and unlock a full day of excitement with a day pass. From 9am in summer and 10am in winter, the jetty is ready with surprises—waiting for you to set off!
