The most dangerous spiders in Australia are fairly distinct, being: Redbacks, Funnelwebs
and Whitetails. Snakes are far more dangerous as they the majority of deaths come from the administration of the incorrect venom. Australian snakes vary in appearance regionally. For instance the Red-Bellied-Black Snake can have almost no red markings in some areas and is confused for a brown or black snake. But anti-venom is much cheaper, because we have healthcare and the price of medicine is regulated. For this there are much fewer deaths than the US.
