Here's some stats that should put your mind at ease. (Suprised on the spider figures. Aussie spiders are pussies)

Snakes: With 41 recorded deaths between 1980 and 2009, snake deaths in Australia average out at less than two per year.
Spiders: Nobody in Australia has died from a spider bite since 1979 after the successful introduction of antivenom for all native species.
Sharks*: Accounted for 25 deaths between 2000 and (March) 2012 in Australia, about 2 a year.
Crocodiles: Historically, crocodiles account for less than one death per year here in Australia, although that is increasing slightly as the crocodile population rises following the ban on crocodile hunting in 1971.
Blue Ringed Octopus: Just 3 recorded deaths in the last century.
Stonefish: One unconfirmed death by stonefish in 1915.
Cone Snails: I could find no recorded deaths from cone snails in Australia whatsoever.
Killer Jellyfish: Jellyfish account for (at time of writing) 66 deaths since records began in 1883. The box jellyfish was responsible for 64 deaths, and the Irukandji the other two. It sounds a lot, but still less than one death per year, more like just half a death per year.
* Updated 5.4.12. with latest shark death figures.

Australia’s worst killers!

Here in Australia, about 20 people a year die from horse riding accidents.
Around 10 people per year in Australia die from European Honey Bee stings after going into anaphylactic shock.
And around 300 people a year drown.

Box jelly fish are very dangerous indeed and can kill a human in minutes.

very very dangerous.

I never truly believe stats from that long ago to be accurate, and Australia is f***ing massive.

How did the box jellyfish death recorder bloke get to hear about old Bruce, who lived in the arse end of nowhere, who's family chucked him on the barbie when they found out he was no longer bonzer?
