The Busselton Jetty is home to one of only five underwater observatories in the world!
Ride the new electric Jetty Train 1.7km out to sea, with 360 degree views across Geographe Bay, and take a tour through the Underwater Observatory at the end of the Jetty. Our experienced guides lead you through the natural wonders that lie beneath the jetty where its piles create Australia’s greatest artificial reef, host to an awe inspiring “forest” of vividly-coloured tropical and sub-tropical corals, sponges, fish and invertebrates.
Descend 8 metres beneath the water’s surface to view more than 300 individual marine species in their natural habitat through eleven viewing windows at various levels within a 9.5 metre diameter observation chamber.
Each year during autumn and winter, the Leeuwin Current brings a narrow band of warm water down the Western Australian coastline. This warm southerly current is responsible for introducing an incredibly diverse array of tropical and sub-tropical species into Geographe Bay, resulting in coral growth at a latitude of 33 degrees south. This is a remarkable phenomenon when compared to the western coastlines of other southern hemisphere continents such as Africa and South America which have no coral growth below 5 degrees south.
Access to the Underwater Observatory is only possible via a tour which includes a complimentary return Jetty Train ride, a 40 minute guided tour of the Observatory with an experienced guide and a Jetty Day Pass.
Tours depart on the hour from the Interpretive Centre (at the base of the Jetty) and take approximately 1 hour and 45 minutes to complete. Book your ticket online, visit the booking office in the Interpretive Centre or phone us on 9754 0900.
Translation sheets for tours in the following languages are available Chinese, Japanese, Indonesian, French, German, Dutch, Italian, Korean and Russian.
