Yes we have some of the most venomous snakes and spiders. Fortunately they aren't overly aggressive like some of the Indian and American snakes, so bites and deaths are very rare. For example the Inland Taipan is the most venomous land snake (some of the coral snakes are more venomous). The only confirmed bites from this snake are amongst people that work with them, and none of them fatal. There are 2 - 3 deaths in Australia every year from snake bites. In comparison hundreds die on the roads.
Well, I think that poor healthcare is of bigger effec than snakes being more or less aggressive... and pressure on their habitats.
