Australia is a land of breathtaking beauty, but it’s also home to some of the world’s most venomous snakes. While spotting a snake might send a shiver down your spine, keep in mind that most snakes would much rather avoid you. They only strike when they feel threatened or cornered—so give them space, and they’ll likely give you peace.
For those who love exploring the great outdoors—whether hiking, camping, or simply enjoying a day in nature, knowing about the snakes in the area and how to stay safe is important.
In this guide, we’ll cover the five most venomous snakes in the Australian Outback. We’ll also provide important safety tips and explain why having a snake bite first aid kit is a must. Being informed can help you enjoy your adventures without any surprises!
The Inland Taipan, also known as the “fierce snake” or “small-scaled snake,” is recognised as the most venomous snake in the world. Despite its deadly venom, it is rarely encountered by humans due to its remote habitat.
Habitat:
The Inland Taipan is native to the semi-arid regions of central Australia, particularly in the Channel Country of southwest Queensland and far northeast South Australia. It thrives in clay plains and can often be found in cracks and crevices of the soil.
Behaviour:
This snake is reclusive and tends to avoid confrontation with humans. It primarily feeds on small mammals, such as rats and mice, using its potent venom to quickly subdue prey.
Venom Potency:
The Inland Taipan possesses the most potent venom of any land snake in the world. Its venom is estimated to be up to 200 to 400 times more toxic than that of a common cobra. A single bite from this snake contains enough venom to kill up to 100 adult humans.
The venom’s extreme toxicity is due to a combination of neurotoxins, myotoxins, and coagulants, which can cause rapid paralysis and internal bleeding.
The Eastern Brown Snake is notorious for causing more fatalities from snake bites in Australia than any other species. Its adaptability allows it to thrive in various environments.
Habitat:
This species is widespread across eastern Australia, inhabiting a variety of environments including dry forests, grasslands, and even urban areas. It is often found near human settlements, where it hunts for rodents.
Behaviour:
The Eastern Brown Snake is diurnal and highly alert. It can be aggressive if threatened, raising its body off the ground and striking with precision. Its venom contains powerful neurotoxins and coagulants.
Venom Potency: While the Eastern Brown Snake’s venom yield is relatively small (around 4mg on average), its potency is remarkably high. The venom contains a powerful mixture of presynaptic neurotoxins, procoagulants, cardiotoxins, and nephrotoxins.
Habitat:
Found along the coastal regions of northern and eastern Australia, including Queensland and northern New South Wales. It favours sugarcane fields and other open areas, where it hunts for rats and other rodents.
Behaviour: The Coastal Taipan is generally shy but can become aggressive when cornered or threatened. It strikes quickly and accurately, delivering venom that affects both the nervous system and blood clotting mechanisms. Venom Potency: The Coastal Taipan’s venom is both highly toxic and delivered in large quantities. It possesses the longest fangs of any Australian elapid snake, reaching up to 12mm in length. This allows for deep venom injection, and studies have shown that the snake can deliver the same amount of venom in subsequent bites.
Habitat:
Tiger Snakes are found in southern Australia, including Tasmania. They prefer wetland areas but are also found in grasslands and forests near water sources such as rivers, lakes, and marshes.
Behaviour: These snakes are generally active during the day but may become nocturnal in hotter weather. They are known for their defensive posture when threatened, flattening their bodies and hissing loudly before striking. Venom Potency: Tiger Snake venom is highly potent and contains a mixture of neurotoxins, coagulants, hemolysis, and myotoxins. The venom’s effects can be severe, potentially causing rapid paralysis, blood coagulation disorders, and breakdown of skeletal muscle tissue. Without prompt treatment, a bite from a Tiger Snake can be fatal. 
Habitat:
Mulga Snakes are widespread across most of Australia except for Victoria, Tasmania, and the southern parts of Western Australia. They inhabit woodlands, shrublands, grasslands, and arid regions.
Behaviour: This species is known for its resilience and ability to thrive in harsh environments. It feeds on other reptiles, birds, mammals, and amphibians. Although not typically aggressive towards humans, it will defend itself vigorously if threatened. Venom Potency: The Mulga Snake’s venom is highly toxic and can be delivered in enormous quantities. Its venom has multiple effects, including hemolytic (breaking down blood cells), cytotoxic (disrupting cells), myotoxic (affecting muscle), and mildly neurotoxic (affecting nerve cells) properties. While not as potent as some other Australian snakes, the large volume of venom it can inject makes it extremely dangerous. 
If you or a companion is bitten by a snake, it’s essential to respond quickly and effectively.
Here’s a step-by-step guide on what to do in this critical situation:
Stay calm and immediately call 000 for emergency assistance.
Use a broad (7.5mm width) bandage to begin firmly wrapping the entire limb, starting at the fingers or toes. If the bandage is too short, start with another bandage where the last one stopped.
Make sure the bandage compression is firm but does not restrict blood flow. Keep the tips of the toes or fingers uncovered so they can be used to monitor blood flow.
Once the whole limb is wrapped, mark where the bite was (this is helpful for emergency service personnel) and then splint the limb to prevent movement.
If possible, try to identify the snake using the Snake ID Card provided in the First Aid Works kit. However, do not attempt to catch or kill the snake.
Do not remove the bandage. Keep the victim still and calm until emergency services arrive. Use the emergency thermal blanket from the kit if the victim goes into shock.
Remember: Do not wash the bite site, apply a tourniquet, or attempt to ‘suck’ out the venom. These actions are ineffective and can be harmful.
With approximately 550 snake bites reported annually, being prepared is not just wise—it’s essential. Whether you’re tending to your garden or trekking through the bush, a snake bite can happen when you least expect it. This is why every Australian should arm themselves with knowledge and a reliable snake bite first aid kit.
Don’t wait for a snake encounter to realise the importance of being prepared. Equip yourself with a snake bite kit today, and embrace your adventures with peace of mind.
Remember, it’s not just about avoiding danger; it’s about being ready to tackle whatever comes your way. With First Aid Works at your side, you’ll be ready to enjoy every moment in Australia’s breathtaking wilderness—because when it comes to safety, preparation is everything!
