　　You might think that with all these dangerous animals Australia is an unsafe place to live in or visit. However, this is far from the truth. There are no more than a handful of shark attacks each year and only three deaths have been reported in the last five years.Similarly, in the last three years there have been only two reported deaths from crocodile attacks. Since 1956, when an anti-venom treatment for redback spider bites was developed, there have been no deaths from redbacks, and since 1981 when a treatment was developed for funnelweb spider poison, there have been no deaths from this spider either. Treatments for jellyfish stings and s~aakebites have also been developed and in the last five years there have been only three deaths from jellyfish stings and about the same number from snakebites.
