Pseudonaja nuchalis, the northern brown snake or gwardar, is a species of very fast, highly venomous elapid snake native to Australia. Its colour and pattern are rather variable, depending largely on its location. The name gwardar is a word meaning "go the long way around" in an Aboriginal language . This may be regarded as advice for people who come across the species in the wild: that is, while P. nuchalis is generally cautious, shy, and inclined to retreat rather than attack, it will defend itself if cornered.
