In short: The Dugite is a slender, nervous snake that has adapted remarkably well to human expansion in Western Australia. Drawn to the house mouse, this reptile is now a common sight near buildings, where it hides under debris and is responsible for the majority of snake bites reported to Perth hospitals.

The Dugite, scientifically known as Pseudonaja affinis, is a member of the Elapidae family and is endemic to the southwestern corner of Western Australia. While it naturally inhabits coastal dunes, heathlands, and woodlands, it has successfully colonized human-altered landscapes, including industrial parks and golf courses. This population increase is largely attributed to the introduction of the house mouse, which serves as a primary food source alongside lizards. In urban settings, these snakes seek temporary shelter under concrete slabs, roofing tin, and other refuse, while in wilder areas, they occupy abandoned termite mounds and rodent burrows.

Physically, the Dugite is characterized by a long, slender body and a small head that is indistinct from its neck. Its appearance varies by subspecies; the mainland P. a. affinis typically ranges from brown to olive-grey with dark spotting, while island subspecies like P. a. exilis and P. a. tanneri are generally smaller and darker. The species is diurnal, showing peak activity during the warmer months from October through April. When threatened, the snake is known for its nervous disposition, often raising its forebody into a tight S-shape and hissing loudly before striking.

Despite its highly toxic venom, the Dugite is not inherently aggressive and generally avoids human contact. Most bites occur when the snake is agitated or cornered. First aid protocols emphasize the use of a pressure-immobilisation bandage to restrict venom spread, followed by immediate professional medical care. Because the snake is common in degraded habitats and has a reliable food supply, experts consider its long-term future to be secure.
