From the ocean to the outback, from the dusty tracks to the stunning blue waters, this is the week of discovery! Ronny is discovering all about life at Carnegie Station, the most remote cattle station in Australia, and is learning more about his own vehicle set up as he travels the Gunbarrel Highway. Mark is discovering not only what fish he can catch in the waters off Rottnest but is also learning the value of keeping your fish skeletons for important research!
