What is the longest jetty in Australia?

The longest jetty in Australia is the Busselton Jetty in Western Australia. It’s 1,841 metres long and comes with a train, underwater observatory and some very unusual diving tours.

The Busselton Jetty in Busselton, Western Australia, is the longest jetty in Australia. Made of wood, this extraordinarily long jetty stretches 1,841 metres into the Indian Ocean.

Busselton Jetty train

The longest jetty in Australia has also become something of a tourism hub. The Busselton Jetty train runs along it for 1.7km. This solar-powered train leaves once every hour, and costs $16 for adults.

That cost covers the $4 Jetty Pass that you normally have to pay for access to the jetty.

At the start of the Busselton Jetty is a blue shed that houses the Interpretive Centre and Museum. Here, you can learn about the history of the jetty since its initial construction in 1865. Touch tables help you see how the structure has changed over the years.

Busselton Jetty Underwater Observatory

Arguably the biggest attraction is at the end of the longest jetty in Australia, however. The Underwater Observatory is eight metres below the water’s surface, and from there you can see how the jetty has become an artificial reef.

There are eleven viewing windows, and from them you can see up to 300 different marine species.

Tickets for the Underwater Observatory cost $37.

Busselton Jetty activities

Around these tentpeg attractions, however, a whole host of activities have sprung up. You can try Scuba diving, or go for an underwater helmet dive. There are also mermaid tours – swimming around dressed as a mermaid – and underwater dining events at the observatory.

There’s also the annual Busselton Jetty Swim – a 3.6 swimming race around the jetty.

Other things to do in Busselton, Western Australia, include whale-watching on Geographe Bay, a high ropes and zipline adventure and spotting woylies on a nocturnal wildlife tour.
