Underwater Observatory

The Busselton Jetty is home to one of only six 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.

The Jetty is excited to launch it’s new Winter Discovery Tour in the Underwater Observatory, from 24th July to 31st August 2017, which feature a unique 3D virtual reality exhibit on the sea floor! As well as a guided tour, tickets also include a return train ride, tea or coffee, USB (with exclusive Jetty videos and photos) and a 50% discount on a Summer Underwater Observatory return ticket!

Access to the Underwater Observatory is only possible via a tour, bookings are essential. Book your ticket online, visit the Interpretive Centre at the base of the Jetty or phone us on 9754 0900.
