The Complete Guide to Identifying the Venomous Snakes of the Great Southern

Stay Safe and Informed in the Great Southern’s Wild Heart

The Great Southern region of Western Australia is a land of breathtaking natural beauty, from rugged coastlines to ancient forests. However, this picturesque landscape is also home to a variety of fascinating wildlife, including some of the world’s most venomous snakes. While encounters are rare if you exercise caution, understanding how to identify these reptiles is crucial for your safety and for fostering a respectful coexistence with nature. This guide will equip you with the knowledge to recognise the venomous snakes you might encounter in the Great Southern.

Understanding Snake Behaviour

Before diving into identification, it’s important to remember that snakes are generally shy creatures and will only strike if they feel threatened. The best defence is always prevention. When exploring snake habitats, wear sturdy footwear, long trousers, and be mindful of where you place your hands and feet, especially in rocky areas, dense undergrowth, and near logs or rocks. Never attempt to handle or provoke a snake. If you see one, keep a safe distance and allow it to move away undisturbed.

Key Venomous Snakes of the Great Southern

1. The Dugite (Pseudonaja affinis)

The Dugite is one of the most commonly encountered venomous snakes in Western Australia, including the Great Southern. These snakes are highly variable in colour, ranging from olive-green and brown to reddish-brown and even grey. They typically have a slender build and can grow up to 1.5 metres in length. Key identification features include their smooth scales, relatively large head compared to their body, and often a distinct dark line running from the eye to the corner of the mouth. They are fast-moving and can be found in a variety of habitats, including coastal heath, woodlands, and agricultural areas.

2. The Tiger Snake (Notechis scutatus)

Tiger Snakes are renowned for their potent venom and striking appearance. As their name suggests, they often display distinct dark bands across their body, alternating with lighter yellow or olive-green bands. However, some Tiger Snakes can be uniformly dark or even lack banding. They are robustly built snakes, typically reaching lengths of 1 to 2 metres. Their head is broad and distinct from the neck. Tiger Snakes are often found in wetter areas, such as swamps, wetlands, and along riverbanks, but can also be found in drier habitats.

3. The Western Brown Snake / Gwardar (Pseudonaja mengdeni)

While often referred to as the Gwardar, this species is closely related to the Dugite and is also venomous. Colouration can vary significantly, from pale tan and brown to darker grey or even reddish hues. They have a more robust build than the Dugite and can reach lengths of up to 2 metres. A key characteristic to look for is their relatively uniform colouration, often lacking distinct banding. They have a moderately sized head and are adaptable to a wide range of habitats across the Great Southern.

4. The Bobtail (Sleepy Lizard) (Tiliqua rugosa)

While not technically a snake, the Bobtail is often mistaken for one due to its elongated body and ability to move with surprising speed. It’s important to note that the Bobtail is a **non-venomous** lizard. Its distinctive features include a blunt, short head, a very short tail that resembles its head (hence ‘Bobtail’), and rough, keeled scales that give it a ‘shingled’ appearance. They are typically brown or grey and are often seen basking in the sun. While harmless, their defensive hiss and ability to puff up their body can be startling.

What to Do if You Encounter a Snake

If you encounter a venomous snake, the most important thing is to remain calm. Do not approach it. Give it plenty of space to retreat. If a snake is in your home or a place where it poses an immediate danger, do not try to capture or kill it yourself. Contact local wildlife removal services or authorities. In the unlikely event of a bite, stay as still as possible, call emergency services immediately, and do not wash the wound or attempt to suck out the venom. Your knowledge and caution are your greatest allies in safely enjoying the natural wonders of the Great Southern.
