On a typical day, she milks - or extracts the venom from - 80 of these Sydney funnel-web spiders. So successful is the antivenom programme here at the Australian Reptile Park that nobody has been killed by one since it started in 1981. In Australia though, those numbers are far lower: between one and four people each year, thanks to its successful antivenom programme. The venom of Sydney funnel-web spiders goes into rabbits, which are immune to the toxins. CSL Seqirus makes 7,000 vials a year – including snake, spider, stonefish and box jellyfish antivenoms - and they are valid for 36 months.
