In episode three John travels deep into tropical Australia. Pedalling through the heat and rain, John takes on a gruelling military fitness test, rides motorbikes with Vietnam veterans, and gets completely caked in mud while working on a banana farm. (It's harder than it looks apparently). As the trip reaches its conclusion John takes in the breathtaking natural beauty of both the Great Barrier Reef, and the Daintree Rainforest, before ending his incredible journey with a surprising personal twist.
