This 1.8 km long timber-piled jetty is the longest of its type in the Southern Hemisphere. Construction began in 1865 and it functioned as a port until 1973, after which it was rescued from decline by a community group now known as the Busselton Jetty Environment and Conservation Association.
It is a paid attraction with profits going back into jetty maintenance and improvement. You can walk the entire length of the jetty, or take the jetty train.
At the beach end is the interpretive centre (free entry), and at the far end is the underwater observatory, which takes you 8 metres below the surface. Fishing and swimming are possible along its length.
Reservations for the train and underwater observatory are essential and can be made online, by phone or in person.
Close to the jetty there is a cafe, beautiful swimming beaches, grassed areas with shade, free public barbecues (just to the east) and the excellent Busselton Skate Park.
