The inland taipan is found in the far southwest of Queensland
The inland taipan (Oxyuranus microlepidotus) is native to the far southwest of Queensland, Australia. It is a highly venomous snake species, with some sources claiming it to be the most venomous snake in the world. Its bite is capable of killing a quarter of a million mice, and its venom is about 50 times more toxic than that of an Indian cobra. Despite its toxicity, there have been no recorded human deaths from an inland taipan bite. This is likely due to the snake's rarity and the remoteness of its habitat.
In Queensland, the inland taipan can be found in the Channel Country region, including areas such as Diamantina National Park, Durrie Station, Morney Plains Station, and Astrebla Downs National Park. The species favours the black soil plains in semi-arid regions, hunting across the cracking clays and loamy soils of the outback floodplains. The inland taipan is a diurnal species, most active during the early morning hours before retiring to shelter for the rest of the day.
The snake's behaviour and physiology are well adapted to its extreme environment. During the hot conditions, it seeks shelter in abandoned animal burrows, deep fissures, rock crevices, and sinkholes. The inland taipan's colour also varies with the season, darkening in the winter to absorb more heat and lightening in the summer to reflect solar energy.
The inland taipan's diet consists solely of mammals, with its primary prey being the long-haired rat (Rattus villosissimus). The snake's population is closely linked to the abundance of this native rodent, which fluctuates with seasonal changes. During good seasons with ample rainfall, the rat population increases, providing a plentiful food source for the taipan. Conversely, during extended droughts, both species' numbers decline.
The inland taipan is a protected species under Australian law, and it is rarely encountered by the average person due to its remote habitat and brief above-ground appearances during the day. While it is known for its extremely toxic venom, the inland taipan is generally considered a shy and placid snake.

It is also found in the northeast corner of South Australia
The Inland Taipan, also known as the fierce snake, small-scaled snake, or western taipan, is native to the far northeast corner of South Australia. This region is characterised by its remote, semi-arid environment, where the species inhabits the black soil plains. The snake's favoured prey is the long-haired rat, a native Australian rodent found in the same habitat. The snake's fortunes are closely tied to those of the long-haired rat, as its primary source of food.
In South Australia, the Inland Taipan has been observed in the Marree-Innamincka NRM District, specifically in the Goyder Lagoon Tirari Desert, the Sturt Stony Desert, Coongie Lakes, and the Innamincka Regional Reserve. An isolated population of the species is also found near Coober Pedy in South Australia. The Goyder Lagoon holds cultural significance for the Aboriginal people, who called the Inland Taipan "dandarabilla".
The Inland Taipan is considered the most venomous snake in the world, with its bite capable of killing a quarter of a million mice. Despite this, there have been no recorded human fatalities from its bite, likely due to its remote habitat and limited distribution in the far southwest corner of Queensland and far northeast of South Australia.
The species is primarily diurnal, most active in the early morning, and briefly basking and foraging before retiring to shelter for the rest of the day. Its olive-brown colour is darker in the winter to absorb more heat and lighter in the summer to reflect solar energy, an adaptation to the extreme temperatures of its habitat.

It is rarely encountered by people
The inland taipan (Oxyuranus microlepidotus) is native to central and eastern Australia in dry areas. It is also known as the fierce snake, the small-scaled snake, or the western taipan. The species is rarely encountered by people due to a combination of factors, including its remote and limited distribution, its brief above-ground appearance during the day, and its shy temperament.
Inland taipans inhabit the far west and southwest of Queensland, extending through the far west of New South Wales into the northeast corner of South Australia, and into the southeast of the Northern Territory. This distribution includes the Channel Country region in Queensland and the Marree-Innamincka NRM District in South Australia. The species is considered to be restricted to the far south-west corner of Queensland and the far north-east of South Australia.
The inland taipan's preferred habitat is the black soil plains in the semi-arid regions where the Queensland and South Australia borders converge. They seek out deep soil cracks and animal burrows, using them for shelter and hunting. The snakes are most active in the early morning, briefly basking and foraging before retreating to shelter for the rest of the day. In cooler weather, they may also be active in the afternoon.
The inland taipan's elusive nature is also attributed to its shy temperament. Despite its fearsome reputation, the species is generally timid and non-aggressive. It is worth noting that the inland taipan is considered the most venomous snake in the world, with its bite capable of killing a quarter of a million mice. However, there have been no recorded human fatalities from its bite, likely due to the rarity of human encounters.
The snake's colouring also contributes to its ability to remain unseen. The olive-brown colour of the inland taipan darkens in the winter and lightens in the summer, allowing it to adapt to its environmental extremes. This colour variation helps the snake absorb more heat in winter and reflect solar energy in summer.

The snake is found in the drainage systems of the Cooper and Diamantina Rivers
The drainage systems of the Cooper and Diamantina Rivers are located in western Queensland, Australia. The Cooper subregion contributes surface water to the Cooper Creek basin and a small proportion to the Diamantina River basin. The river basins are characterised by large variations in discharge and flow duration. The flow regimes of the Diamantina River are dominated by late summer flow events resulting from highly variable monsoonal rainfall in the upper catchments. The streams are ephemeral due to the location of the catchment, which includes semi-arid and arid regions. The Diamantina river basin has few gauging stations to record streamflow, with two stations currently operating: one at Oondooroo on the Mills Creek and the other at Diamantina Lakes on the Diamantina River.
The Cooper Creek basin, on the other hand, has a long-term average modelled runoff coefficient that varies from a low of 1.2% for the Alice River at Barcaldine to a high of 6.6% for the Thomson River at Stonehenge. Streamflow in the basin varies greatly between years and months, with some months having no flow. The maximum monthly flow depends on the location of the gauging site and contributing catchment area, with some sites having very high flows (up to 15,900 GL/month for Cooper Creek at Currareva). The Cooper Creek basin experiences rare, ephemeral flows due to local rainfall and is inundated up to 5% of the time.
The Cooper and Diamantina Rivers are globally significant rivers in the Channel Country of western Queensland. The Queensland Government has permanently protected these rivers under the Wild Rivers Act, which will benefit the region's natural environment and create confidence for graziers over water supplies. The protection of these rivers has been hailed as a successful example of consensus-driven community policy development in Australia, involving Traditional Owners, catchment and natural resource management groups, mayors, and conservation and producer organisations.

It is also found in the Marree-Innamincka NRM District in South Australia
The Inland Taipan, also known as the Western Taipan, Small-Scaled Snake, or Fierce Snake, is native to central and eastern Australia in dry areas. It is found in the far west and southwest of Queensland, extending through the far west of New South Wales into the northeast corner of South Australia, and into the southeast of the Northern Territory. In South Australia, the snake has been observed in the Marree-Innamincka NRM District, which includes the Goyder Lagoon Tirari Desert, the Sturt Stony Desert, the Coongie Lakes, the Innamincka Regional Reserve, and Oodnadatta. The Goyder Lagoon, in particular, holds cultural significance for the Aboriginal people, who referred to the Inland Taipan as "dandarabilla".
The Marree-Innamincka NRM District is located in the remote, semi-arid regions of South Australia, where the Queensland border converges. The area is characterised by black soil plains and is known for its extreme environmental conditions. The Inland Taipan has adapted to these conditions by adjusting its colouration—its olive-brown scales darken in the winter to absorb more heat and lighten in the summer to reflect solar energy.
The Goyder Lagoon, part of the Marree-Innamincka NRM District, is of particular cultural significance to the Aboriginal people from the region. They had a traditional name for the Inland Taipan, "dandarabilla", reflecting their knowledge and connection to the local flora and fauna. This name originates from the place now called Goyder Lagoon in north-east South Australia.
The Inland Taipan is a highly venomous snake species, considered to have the most toxic venom of any land snake in the world. Its venom is a potent cocktail of enzymes and agents that paralyse nerve endings, destroy muscle tissue, and cause severe bleeding. Despite its toxicity, there have been no recorded human fatalities from the Inland Taipan's bites, likely due to its remote habitat and limited distribution.
