Vet Mark Evans has spent the last few weeks tackling the most deadliest predators in order to prove that they don't need to be killed - we can all live peacefully together. A dangerous mission if there ever was one. Tonight he goes to Australia, the land where pretty much everything wants to kill you. On the west coast, seven people have been killed by sharks in the last three years, with authorities responding by catching and killing any creature that are deemed a threat. As usual, Mark thinks there has to be a non-lethal solution. He tests a new multispectral camera that spots the ferocious fish from the air even when they are hidden several metres underwater. Then he goes swimming with the Great Whites to attach tracking tags to them.... which pretty much sounds like the worst idea in the world but we're sure he has lived to tell the tale. Well, pretty sure.
