Top 10 Venomous Snakes in Australia... Including Signs and Symptoms

Posted by Afterpay Afterpay on

As the weather warms up and we start becoming more active outside, we all know that so do snakes. Activities like hiking, swimming, bush walking, camping are starting to become so much more inviting, and we of course want to share this with our dog. Watching him run, jump and splash is so enjoyable that we do not want him to miss out.

 

But, while it is easy and common to just think about dogs being out and about, our cats are at just as much risk… if not more!

 

While we keep our dogs close and know where they are at all times, allowing us a quick response in a snake bite, cats are often roaming free. Not many owners can say exactly where their cat has been and what they have been up to that day. If a cat gets bitten whilst roaming, there is a much lower chance of him making it back to the family home and surviving for treatment.

 

To top it all off, we live in Australia with everything that wants to bite you!

 

 

Australian Snakes

In Australia, we have approximately 170 snakes, with 100 of them being venomous. Even more alarming is that around 6,500 dogs were bitten by a snake in the last year. Scary isn’t it!

 

 

Our top 10 venomous snakes are:

 

 

1.     Eastern brown snake

 

Also known as: common brown snake

 

Found: throughout the eastern half of mainland Australia

 

Fast-moving, aggressive and known for their bad temper, eastern brown snakes, together with other browns are responsible for more deaths every year in Australia than any other group of snakes. Not only is their venom ranked as the second most toxic of any land snake in the world (based on tests on mice), they thrive in populated areas, particularly on farms in rural areas with mice.

 

2. Western brown snake

Also known as: gwardar


Found: widespread over most of mainland Australia – absent only from the wetter fringes of eastern Australia and south-western Western Australia

 

Said to be less aggressive than its eastern cousin, the western brown snake is still highly dangerous and part of the group of snakes that causes the most fatalities in Australia.Western browns tend to be fast moving and nervous in temperament. When disturbed, they will run for cover, striking quickly if cornered, then making a quick getaway.

 

Though their venom is not as toxic as the eastern brown’s, they deliver three times as much. Bites are usually painless and difficult to see due to the small fang marks. 

 

 

 

3. Mainland tiger snake

Also known ascommon tiger snake


Found: along the south-eastern coast of Australia, from New South Wales and Victoria to Tasmania and the far corner of South Australia

 

Mainland tiger snakes are responsible for the second-highest number of bites in Australia, as they inhabit highly populated areas along the east coast, including some metropolitan areas of Melbourne. They are attracted to farms and outer suburban houses, where they hunt mice nocturnally and can easily be trodden on by unsuspecting victims in the darkness.

 

 

 

4. Inland taipan

Also known asfierce snake or small-scaled snake


Found: in cracks and crevices in dry rocky plains where the Queensland, South Australia, New South Wales and Northern Territory borders converge

 

Reclusive and rare, the inland taipan hides out in its remote, rocky habitat. This snake only makes the top 10 because of its highly toxic venom, considered to be the most potent of any land snake in the world; it has the potential to kill an adult human within 45 minutes.

 

Hunting in the confined space of the burrows of the long-haired rat, the inland taipan uses its potent venom to finish off prey quickly, injecting more than 40,000 times the amount needed to kill a 200g rat. The prey has little chance of fighting back.

 

 

 

5. Coastal taipan

Also known as: eastern taipan


Found: in an arc along the east coast from northern New South Wales to Brisbane and northern Western Australia. They are fond of sugarcane fields.

 

Coastal Taipans are equipped with the longest fangs of any Australian snake (13mm), and have the third most toxic venom of any land snakes.

 

Extremely nervous and alert, they put up a ferocious defence when surprised or cornered, ‘freezing’ before hurling their lightweight body forward to inflict several lightning-fast snapping bites. However, they’re not usually confrontational and would much rather escape any threat.

 

 

 

6. Mulga snake

Also known asking brown snake 


Found: throughout Australia, except in Victoria, Tasmania and the most southern parts of Western Australia – the widest distribution of any Australian snake

 

The mulga is the heaviest venomous snake in Australia and has the largest-recorded venom output of any in the world – delivering 150mg in one bite; the average tiger snake only produces 10-40mg when milked.

 

Their temperament seems to vary with locality. Southern mulgas are reported to be shy and quiet, whereas northern specimens are much more agitated if disturbed – when they throw their heads from side to side and hiss loudly. Mulgas bite savagely, even hanging on and chewing as they inject massive amounts of highly toxic venom, which destroys blood cells and affects the muscles and nerves.

 

Though commonly known as a king brown snake, the mulga is actually a member of the black snake genus Pseudechis, and black snake antivenom is needed to treat a bite.

 

 

 

7. Lowlands copperhead

Also known as: common copperhead


Found: in relatively cool and cold climates in south-eastern Australia, southern Victoria, Tasmania and the islands of Bass Strait

 

The lowlands copperhead is the only venomous snake found above the snow line, active in weather usually considered too cold for snakes. A water lover, copperheads snakes are at home around dams, soaks, canals, drainage ditches and along the verges of roads.

 

Copperheads are shy and prefer to avoid humans, though they live in populated and agricultural areas. If cornered, they will hiss loudly, flatten their body and flick or thrash about, usually without biting. With further provocation they may lash out, though they are slow to strike and can be inaccurate.

 

Copperhead venom is neurotoxic (damaging nerves), ruptures the blood cells and damages the cells and muscles.

 

 

 

8. Small-eyed snake

Also known aseastern small-eyed snake


Found: widely distributed along the east coast, from Victoria to Cape York

 

At about 50cm long, the small-eyed snake may be petite but its venom can pack a punch and shouldn’t be underestimated. Little is known of its toxicity, but bites have caused illnesses in snake handlers and there has been one known fatality. The venom contains a long-acting myotoxin that continues to attack muscle tissue (including the heart muscle) for days after the bite.

 

Though common, small-eyed snakes are secretive night-dwellers and therefore don’t often come into contact with humans. Coloured black or dark grey with a silvery belly, they blend into the night. When disturbed they may thrash about aggressively, but are not usually inclined to bite.

 

 

 

9. Common death adder

Also known assouthern death adder


Found: in eastern Australia (except the far north and south), southern South Australia and Western Australia

 

The common death adder is an ambush predator that sits motionless, concealed in leaf litter, sand or gravel, twitching the worm-like lure on the end of its tail to attract prey.

 

Unlike other snakes that flee from approaching humans crashing through the undergrowth, common death adders are more likely to sit tight and risk being stepped on, making them more dangerous to the unwary bushwalker. They are said to be reluctant to bite unless actually touched.

 

 

 

10. Red-bellied black snake

Also known ascommon black snake


Found: distributed down the east coast (though not to Tasmania) and slightly into south-eastern South Australia

 

The red-bellied black snake is somewhat less venomous than many other Australian snakes, but you’re more likely to come across it in urban areas and its bite is certainly no picnic, causing significant illness and requiring medical attention.

 

Red-bellied blacks are one of the few large venomous snakes still found in the Sydney region, and at 2m-long are capable of eating other snakes. They are not particularly aggressive and will escape from humans if possible, but when threatened will flatten their bodies and hiss loudly.

 

The venom causes blood-clotting disorder and muscle and nerve damage.

 

 

Common signs and symptoms of a Snake Bite 



  • Weakness or severe lethargy Collapse
  • Shaking or twitching
  • Dilated pupils or difficulty blinking
  • Vomiting
