Busselton Jetty Observatory South Window

A Southern Vantage on the Reef

Set into the far end of Busselton Jetty, this south-facing window looks onto a stretch of the jetty's submerged piles where soft corals and sponges cling to century-old timber. The vantage complements the observatory's other windows, each framing a slightly different slice of the same artificial reef.

A Century of Marine Colonisation

Since the jetty's construction in 1887, its submerged structure has become a haven for more than 300 marine species — reef fish, sponges and soft corals that would have no foothold on this otherwise sandy coastline. The south window offers a shifting, ever-populated cross section of that accidental habitat.

Conservation Through Tourism

The jetty and its Underwater Observatory are maintained by Busselton Jetty Incorporated, a community non-profit that reinvests ticket revenue into the structure's ongoing restoration and the reef's long-term conservation.

Reaching Busselton, Western Australia

The jetty stretches out from the coastal town of Busselton, gateway to the Margaret River wine region. Visitors reach the observatory on foot or aboard the jetty's heritage train, crossing nearly two kilometres of Geographe Bay to reach the windows below.
