Underwater Observatory - Busselton Jetty

Explore one of only six underwater observatories in the world at the Busselton Jetty! Bookings essential for tours.

Your Underwater Observatory tour starts with a relaxing train ride on the Stocker Preston Express along the length of the Jetty with 360-degree views across the Indian Ocean. One of our friendly tour guides will greet you at the end of the Jetty to guide you through the Underwater Observatory. As you descend 8-metres below the ocean’s surface you will be lead 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.

Discover more than 300 individual marine species in their natural habitat through eleven viewing windows at various levels within the 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 Underwater Observatory provides visitors with the opportunity to view amazing marine life as they descend 8 metres to the ocean floor via a spiral staircase.  There are eleven viewing windows at various levels within the chamber allowing visitors to view Geographe Bay’s amazing underwater garden. Described as Australia’s greatest artificial reef, the Busselton Jetty is host to an awe inspiring forest of vividly coloured tropical and sub-tropical corals, sponges, fish and invertebrates. Provision of a lift within the Observatory ensures that this amazing experience is available to all.  The experience doesn’t need to end there! Why not take a dip, throw a line in or visit the Interpretive Centre and Heritage Museum.
