Australian Snake Identification and Snakebite Incidence
Did you know that 20 of the 25 most venomous snakes in the world are found in Australia? Australia is the only continent where venomous snakes (70%) outnumber non-venomous ones. Australia's deadliest snakes are the brown snakes (responsible for around 60% of deaths caused by snakebite) and the venomous land snake on Earth (tested on mice) is the Inland Taipan found in arid regions of central Australia.

Identification and snakebite incidence
Identification or description of the snake is very crucial because not all snakes are venomous, and because different kinds of anti-venom exist for every species of snake. Doctors may use a Snake Venom Detection Kit (SVDK) to determine the specific type of snake by examining the traces of venom left in the bitten area.
It is estimated that between 50,000 and 60,000 people die of snake bite each year around the world. By comparison, in Australia, it is estimated snakebites incidence are between 3 and 18 per 100,000 with an average mortality rate of 4 per 100,000 per year.
Some deaths are sudden, however it is uncommon to die within four hours of a snake bite. If untreated, high levels of venom could cause death in a short time. Despite of this, very few deaths result from snake bites because of the availability and wide access to anti-venom in recent years.
Snakes should be treated with respect
Snake venoms are a complex mixture of polypeptide and other molecules that adversely affect multiple homeostatic systems within their prey in a highly specific and targeted manner. Amongst the most potently toxic venoms in the world are these major Australian venomous snakes.

Snakes are shy by nature and will only bite animals or humans if they feel threatened or looking for food. Subsequently, most snakebites occur when people try to catch or kill them.
