To the longest wooden jetty in the southern hemisphere with an Underwater Observatory

Located 1.8 kilometres towards the end of the Jetty, the Underwater Observatory has been designed to accommodate up to 40 people at one time. Descending 8m beneath the water's surface, visitors can view the amazing corals and fish life through eleven viewing windows, all at various levels within a 9.5 metre diameter observation chamber. A lift within the observatory also enables wheelchair bound people to have access to one of Western Australia's unique natural wonders.

Described as Australia's greatest artificial reef, the Busselton Jetty, with more than 300 individual marine species, is host to an awe inspiring "forest" of vividly-coloured tropical and sub-tropical corals, sponges, fish and invertebrates.

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 in itself is a remarkable phenomenon when compared to the west coast of other southern hemisphere continents such as Africa and South America who have no coral growth below 5 degrees south.
