Jase and Simon have a plan to load their quad bikes on tinnies and punt them along the river to the beach. A nasty surprise puts an end to their mission and leaves them fighting for survival without any support in the remote outback.
Jase and Simon head to a remote tropical island on the hunt for artefacts from a colonial expedition. But first, they have to drive over a rough track, pass through boggy marshland, and launch their boat on a coastline crawling with crocs.
Jase and Simon upgrade and up-armour the Unleashed Swamper and put it through its paces to prepare for a new mission on the other side of an impenetrable forest.
With the Unleashed Swamper broken down in dense bushland, Jase leaves Simon to find spare parts in a remote township. Their only option is to try and fix the Swamper where it sits before continuing the search for a WWII plane wreck.
Jase and Simon use the Swamper to help a friend check the fences on his million-acre property after a tropical cyclone, but the storm has left them with a boggy terrain to conquer.
