How do Australians survive if it has the most poisonus creatures on earth?

The waters surrounding Australia have some of the world's most dangerous sharks & jellyfish, the beaches have Cone Snails which have a highly poisonus stinger, on land there's vicious crocodiles, some of the most venomous snakes on the planet, many poisonus insects and spiders which can get into people's homes are everywhere, and even one of the world's only egg laying mammals, the platypus, has a venomous stinger on it's feet. I understand most of these animals can be avoided by not swimming in the ocean or by staying in cities and not going out alone in the wilderness, but it's the various dangerous and highly poisonus spiders and insects which people can be in contact with on a daily basis that scares me. Do Australians see these dangerous creatures every day?
