In episode four, Steve is in Australia, infamous as the ‘home of the deadly', with more lethal snakes than any other country, dangerous spiders, great white sharks and salt-water crocodiles.

This week in the final episode of the series, Steve is in the vast nature reserves of South Africa.

He goes in search of a pack of rare and endangered African wild dogs, he helps capture and tag a magnificent martial eagle. He gets hands on with a venomous spitting cobra and a puff adder as they strike and he risks life and limb to kayak up close to Africa's most dangerous mammal, the highly unpredictable hippopotamus.
