Taipan inland taipan is considered to be the most venomous land snake and the coastal taipan, which is arguably the largest Australian venomous snake, is the third-most venomous land snake. The central ranges taipan has been less researched than other species of this genus, so the exact toxicity of its venom is still not clear, but it may be even more venomous than the other taipan species. Apart from venom toxicity, quantities of venom delivered should also be taken into account for the danger posed. The coastal taipan is capable of injecting a large quantity of venom due to its large
Coastal taipan being bitten, but the average is around 2.5 hours. The time between a bite and death depends on various factors such as the nature of the bite and the constitution of the victim. Untreated bites have a mortality rate of 100% as the coastal taipan always delivers a fatal dose of venom (an average bite delivers 10-12x the lethal dose of venom for a human adult male), and medical professionals recommend that victims seek immediate medical attention even for apparently minor bites. Before the introduction of specific antivenom by the Commonwealth Serum Laboratories in 1956, nearly all bites were fatal.
