Tiger snakes are a venomous snake species native to Australia. They are found mainly in south-eastern and southwestern Australia, including Queensland, New South Wales, Victoria, South Australia, and Western Australia, as well as Tasmania and offshore islands. They favour habitats near water, such as wetlands, creeks, and rivers, and are excellent swimmers and climbers. While they are known for their distinctive tiger-like stripes, their colouration and patterning can vary significantly, and they may even be unbanded. They are generalist predators, typically hunting during the day and feeding on a variety of prey, including frogs, lizards, birds, and small mammals. Despite their fearsome reputation, tiger snake encounters are rare, and they are more likely to be affected by human modification of their environment than to cause harm.
| Characteristics | Values |
|---|---|
| Location | South-eastern, southern, and southwestern mainland Australia, including Queensland, New South Wales, Victoria, South Australia, and Western Australia. They are also found in Tasmania and offshore islands. |
| Habitat | Tiger snakes favour wetlands, creeks, dams, and other habitats near water sources, or shelter near permanent water sources in pastoral areas. They are often found in locations with plenty of hiding covers, such as fallen timber, deep vegetation, and empty burrows. |
| Diet | Generalists, with a varied diet that includes frogs, lizards, small mammals, birds, fish, tadpoles, and invertebrates. Insular populations may feed exclusively on scincid lizards or take advantage of seasonally available food sources like mutton-bird chicks. |
| Behaviour | While typically ground-dwelling, tiger snakes are capable swimmers and excellent climbers, having been spotted up to 10 metres above the ground in both natural and urban environments. They are active during the warmer months and may also bask on warm winter days. They aestivate in animal burrows, under boulders, or in standing dead trees during cool periods. |
| Venom | Tiger snake venom contains potent neurotoxins, coagulants, haemolysins, and myotoxins. The venom yield is 35-65 milligrams, while the lethal dose for humans is 3 milligrams. |
| Danger to Humans | Tiger snakes are one of Australia's most venomous snakes and are responsible for a significant percentage of snakebite incidents in the country. They are not inherently aggressive but will bite if interfered with. Their bites can cause localized pain, tingling, numbness, sweating, breathing difficulties, and paralysis. Anaphylaxis, a severe allergic reaction to the bite, can be fatal within 15 minutes. |
| Treatment | The recommended treatment for a tiger snake bite is the pressure immobilization method, followed by the administration of Seqirus (bioCSL) Tiger Snake Antivenom (TSAV). |

What You'll Learn
Tiger snakes are found in coastal regions of Australia
Tiger snakes are found in the coastal regions of Australia, typically in locations with plenty of hiding spots and access to water. They favour wetlands, creeks, dams, and other habitats near watercourses, or shelter near permanent water sources in pastoral areas. They are also found in rivers, lakes, swamps, and lagoons. Tiger snakes are excellent swimmers and climbers and have been spotted in trees and buildings, as well as 10 metres above the ground in both natural and urban settings.
Tiger snakes are a large group of distinct populations with extreme variance in size and colour. They are typically identified by their banding, black and yellow like a tiger, but some do not have stripes and can be olive, orange-brown, or jet black. They usually grow to about 1 to 2.1 metres long, with an average total length of around 1.2 metres. They are generalists in their diet, which includes frogs, lizards, small mammals, birds, fish, tadpoles, and invertebrates. They are also known to practise cannibalism.
Tiger snakes are found in south-eastern, southern, and southwestern mainland Australia, including Queensland, New South Wales, Victoria, South Australia, and Western Australia. They are also present in Tasmania and offshore islands, such as Chappell Island and Roxby Island. In Melbourne, they are commonly found in the western suburbs. In Queensland, they inhabit isolated locations like the Carnarvon Ranges, Cooloola, and the Bunya Mountains.
Tiger snakes are venomous and considered dangerous to humans. Their bite can cause localized pain, tingling, numbness, sweating, breathing difficulties, and paralysis. They are the second deadliest snake in Australia in terms of human fatalities, after the brown snake. However, the availability of antivenom has significantly reduced the number of fatal tiger snake bites.

They are also found in Tasmania and offshore islands
Tiger snakes are found in Tasmania and offshore islands, in addition to the coastal regions of southern Australia. The species is highly variable in colour and patterning, with banding in black and yellow like a tiger, though some are unbanded. They are usually ground-dwelling but can swim and climb trees and buildings.
In Tasmania, the diet of the tiger snake includes larger quantities of mammals and birds. The tiger snake population in the Flinders Range, South Australia, and on Chappell Island, Tasmania, are listed as vulnerable. The Chappell Island tiger snake is the largest of the species, averaging 1.9 m (over 6 ft) in length. It has a blunt head distinct from its robust body, and its colour is olive-brown to almost black, sometimes with lighter crossbands. The ventral surface is usually lighter in colour.
The King Island and Tasmanian tiger snakes also have blunt heads distinct from their robust bodies. They can grow up to 1.5 m (4 ft 11 in) in length. Dorsally, they may be jet black, grey with black flecks forming faint bands, or an unbanded grey or brown. The ventral surface is usually a lighter colour. On the main island of Tasmania, males can be mature at a mass of 500 g, and females can be mature at a snout-vent length of 850 mm and a mass of at least 325 g.
Tiger snakes are also found on other offshore islands, including Carnac and Garden Islands in Western Australia, and Kangaroo Island in South Australia. On Kangaroo Island, specimens are highly variable in colour, often exhibiting banding and uniform brown colours. Some even possess red bellies.

Tiger snakes are common in south-eastern and south-western Australia
Tiger snakes are native to Australia and are found in several regions across the country. They are common in south-eastern and south-western Australia, including Queensland, New South Wales, Victoria, South Australia, and Western Australia. They are also present in Tasmania and some offshore islands.
In south-eastern Australia, tiger snakes can be found in Queensland, specifically in isolated locations like the Carnarvon Ranges, Cooloola, and the Bunya Mountains. They are also present in southern and eastern New South Wales, with a notable population in the western suburbs of Melbourne, Victoria. Most parts of Victoria fall within their range, as well as the Bass Strait islands.
In south-western Australia, tiger snakes are found in Western Australia, particularly in the coastal regions. They favour habitats near water, such as creeks, rivers, lakes, dams, and wetlands. These snakes are excellent swimmers and climbers, which aids in their ability to navigate and hunt in these environments.
The distribution of tiger snakes extends across diverse habitats, from the coastal areas of Western Australia to South Australia, Tasmania, Victoria, and New South Wales. They are highly adaptable and can survive in both subtropical and temperate regions. Their habitat preferences include pastoral areas with permanent water sources, providing them with ample opportunities for prey and shelter.
Tiger snakes are large, venomous snakes that can grow up to 1 to 2.1 meters in length. They are known for their distinctive tiger-like stripes, with banding in black and yellow, although individual snakes can vary significantly in colouration and patterning. Some may even be unbanded. They are generalists in their diet, primarily feeding on frogs and lizards but also occasionally preying on small mammals and birds.

They are often found near bodies of water
Tiger snakes are found in south-eastern and southwestern Australia, including Queensland, New South Wales, Victoria, South Australia, Western Australia, and Tasmania. They are also found on offshore islands, such as the Bass Strait islands. These snakes are typically found near bodies of water such as creeks, rivers, lakes, dams, lagoons, wetlands, and swamps. They are generalists when it comes to their diet, and their prey includes frogs, lizards, small mammals, and birds.
Tiger snakes are a large group of distinct populations with extreme variance in size and colour. They are usually identified by their banding, which is similar to that of a tiger, with yellow, brown, and black cross-band patterns. However, some tiger snakes do not have stripes on their scales, and their colouration can vary from pale to dark patterns. The underside of the snake is usually unbanded or lighter than its dorsal scales. The average total length for mainland tiger snakes is around 1.2 metres, although they can reach up to 2.4 metres in length.
Tiger snakes are often found near bodies of water as they provide an abundant source of prey. They are generalists and opportunistic feeders, which means they will take advantage of whatever food sources are available. For example, on Chappell Island, tiger snakes are very large and feed on fat muttonbird chicks, which are seasonally abundant. In contrast, on Roxby Island, where there are no nesting seabirds, the dwarf population of snakes survive mainly on small skinks.
Tiger snakes are venomous and considered dangerous to humans. They are one of Australia's most notorious species of venomous snakes, and their bite can be fatal. The availability of antivenom has helped reduce the number of fatal tiger snake bites. Tiger snakes are also prey to birds of prey, ibises, and kookaburras. They are often found near bodies of water, which can provide cover and hiding places, such as fallen timber, deep vegetation, and empty burrows.

Tiger snakes are excellent climbers
Tiger snakes are highly venomous snakes found in southern Australia, including its coastal islands and Tasmania. They are usually found in coastal regions, wetlands, creeks, dams, and other habitats with water sources. They are typically ground-dwelling and are excellent swimmers, but they are also adept at climbing.
Tiger snakes are large snakes, with an average total length of around 1.2 meters, although they can reach up to 2.1 meters in rare cases. They are known for their distinctive banding, typically black and yellow like a tiger, but they can also be unbanded and exhibit extreme variance in colour and patterning. The ventral surface, or underside, of the snake is typically light yellow or orange, while the dorsal surface can vary from olive, yellow, orange-brown, or jet-black.
The climbing abilities of tiger snakes can be attributed to their robust and muscular build. They have a flat, blunt head that is slightly distinct from their robust body, giving them a balanced profile for climbing. Additionally, their scales provide traction and flexibility, enabling them to navigate branches and other climbing surfaces effectively.
Tiger snakes are feared due to their aggressive nature and toxic venom. Their venom contains potent neurotoxins, coagulants, haemolysins, and myotoxins, which can be fatal to humans. When threatened, tiger snakes flatten their bodies and raise their heads in a classic pre-strike stance. Despite their fearsome reputation, human modification of the environment has led to a decline in their numbers, and they are now rarely encountered.
