Living in Britain, one encounters a regular series of stories about how dangerous Australian animals are. (Otherwise, the UK media treat Australia pretty much the way the Australian media treat New Zealand.) And most people accept this as gospel, to the extent that it's often given as a reason for not visiting Australia. In fact, this is complete nonsense: cows kill as many people in the UK each year as all of Australia's "dangerous" animals put together.
In Australia, on average each year fewer than two people die from snake bites, perhaps one and a half from shark attacks, fewer than one a year from crocodiles, and fewer than one a year from jellyfish, octopuses, stonefish and so forth put together. No one has died from spider bites in the last fifty years.
Meanwhile, cows kill about five people a year in the United Kingdom. (Cows kill few people in Australia because walking routes are almost almost all in national parks rather than farmland, as there are few rights of way there.)
