Robson Green is quite the perplexing fellow. Whenever you see him acting, he comes across as the thoughtful, sensitive type. Then you see him on Extreme Fishing with Robson Green and he's a frightening, foul-mouthed lunatic who turns the air blue in his unhinged excitement at being able to drag large animals around on barbed metal hooks.  
Thankfully, in Robson Green's Australian Adventure he's in a much saner mood - and he even has quite a nice turn of phrase. The opal fields of Coober Pedy, he tells us, are "a lunar landscape with a giant mole problem". Green begins his antipodean odyssey in South Australia tonight, and he's clearly on a mission to ensure that the viewers back home in Britain are left in no doubt whatsoever that this is indeed the driest state in the driest inhabited continent on the planet. In Adelaide he meets a Hulk Hogan lookalike who works as a snake catcher, and he proves a fast learner when it comes to picking up a comparatively docile red-bellied black snake by hand and stick. Then it's off up to Coober Pedy, where he meets some hardy old characters who keep drilling for opals year after year, even though it can be years between decent paydays. Having tried his hand at the slightly scary and claustrophobic task of being lowered down narrow shafts to look for opal-bearing rock, he's off on another adventure - and then another. There's a 600-kilometre mail run with a postie who also delivers sizeable quantities of booze to remote cattle-stations. Then there's an overnight expedition with cowboys engaged in the difficult job of roping and tagging large and ornery calves. After that he winds up in the Flinders Ranges, where he meets some of the traditional owners of the land and visits an ancient ochre quarry. The episode ends on a particularly poignant note with Green learning to sing the blues in an ancient language that's now spoken by just 20 people. British viewers have seen so many of these celebrity travelogues over the years that Green's itinerary will be almost as familiar to them as it is to us. But these things can still be worth a look, depending on who's doing them. Green might not be as entertaining as a Billy Connolly, but he's certainly not the most insufferable celeb to have been handed a pile of cash and a plane ticket to these parts.
