Dunno if it's still true, but as of 2 year ago no one had died in australia that had followed correct first aid.
On the topic of having appropriate anti venom i checked with our hospital today. Turns out they had it for brown and black snakes. Turns out i just removed a mulga from a large accomodation camp tonight so if things had gone pear shaped i would have been sweet. Its funny as i have had no callouts for a couple of weeks then on the day i check about the anti venom......
