About All 4 Adventure Season 10, Episode 4 : Episode 4

The crew have left Darwin and are entering Arnhem Land at Cahill's Crossing. They need to make a remote barge landing on the high tide to reach Elcho Island, and the tide waits for no man. So they are on the clock. But one problem after another threatens their plans. A broken u-bolt leaves the boat trailer in pieces, and there's no choice but to come up with a bush-mechanics fix. Even after they're moving again, the boggy, overgrown road keeps setting back the clock when time is of the essence. Will they make their barge or have to come up with another plan?
