A mere 10 minutes by car from the resort, you can visit one of Western Australia’s wonders. A man-made one. Busselton Jetty is claimed to be the longest wooden structure in the southern hemisphere, stretching for almost 2 km out into the sea. The pier was built in the mid-19th century to accommodate ships that were too large to enter the bay’s shallow waters. Ships no longer dock there, but there’s plenty to see and do. You can ride an electric train to the end of the jetty, where an underwater observatory sits submerged 8 metres below the surface. From its windows, you can gaze into a fascinating world filled with brightly coloured fish and corals.
