Once off the boat we had a long, difficult walk over sand slippery boulders, and a short boardwalk (which gets removed by helicopter at the start of the wet season) to get to where the spectacular Twin Falls makes it's way over the edge of the escarpment to the Kakadu floodplain below.
Steve was a bit younger than us: curly long grey hair, no hat, beer belly and surf sandals (get the picture). He was also carrying a pack with all our lunches and spare water. He still managed to dance over those boulders, while I made every gingerly step a very considered and sweaty one!
He was also a politics junkie - knew as much as we did about the minutiae of current federal politics (if not more). Apparently he quizzes all his clients about what they think of Tony Abbott. He reckons 98% of his clients think he will never be Prime Minister!
