Jase and Simon start out having a good look at the Southern Ocean at the Eucla jetty, which was an essential part of the nation’s telegraph history, before heading further west, the boys head north to reach a cave they’ve heard about and do a little spelunking. The next morning, they take the buggies out to check out the track (and to have a little fun). They determine the trucks will be able to get through to a point, and the beach is always another option. They then hit the beach to try and reach their goal of Eyre telegraph station.
