The Lowland copperhead (Austrelaps superbus) is a venomous snake species in the family Elapidae. It is found in south-eastern Australia, including Tasmania. It is commonly referred to as the copperhead, but is not closely related to the American copperhead, Agkistrodon contortrix. If provoked, the Lowland copperhead is a dangerous snake with neurotoxic venom, which can kill an adult human if correct first aid is not applied promptly.
