The dugite is limited to a small area of the southern coast of Western Australia and South Australia. Much of this area is highly populated, so dugites are a relatively frequent cause of snakebite here. Dugites are considered more aggressive than the western brown snake (gwardar). The adult is usually olive green to brown, often with dark spots or flecks. The abdomen may also be dark, unlike that of other brown snakes.
The average venom yield is around 6mg, the record being 17mg. Like other brown snakes, the venom is neurotoxic and procoagulant. It is less toxic by weight than that of the common brown snake or the gwardar.
