Jase and Simon head back down the river in the rubber boat on their way back from the secret waterfall in last episode. It's a good time to drop a line. Jase catches his big toe, and Simon catches a big barra! Back at the trucks, they cross to hook up the big trailer again, and then have to make their way back through the rocky headlands. As the tide starts to turn, some trouble comes up. Just as they are about to head for the Frenchman's Track, a terrible noise brings them to a grinding halt... literally. The bushes in the trailing arms have collapsed, and this does not bode well for any progress they'd planned for the day. Instead they head for Weipa to wait for a plane to bring some spare parts. To pass the time, Jase cooks up a special choc chip cheesecake for Simon's birthday. After using the airport parking lot as a makeshift workshop, they are back in action heading east again. 90mm of rain fell overnight making the track a bit greasy. It also means the river is higher, so they make the call to wait until morning to cross the Wenlock. Instead of falling overnight, the water has risen. Simon walks the crossing, but once Jase starts heading down with the truck, it becomes clear that it's not going to happen this time. Unfortunately, getting back up the bank proves to be a serious challenge even after taking off the ATV to lighten the load. They determine the best way out is up the parallel track, but doing a 3-point turn in a rapidly moving river isn't without its difficulties. But soon they are pointed in the right direction and are able to winch off Simon's truck. Back up on drier ground, Simon manages to roll his trailer. This track is really giving these guys a run for their money, but thankfully the trailer survives.
