The Underwater Observatory
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.
