Although its venom is the deadliest in the world, no one in Australia has died of a funnel-web bite since the introduction of an antivenom in 1981, despite the 30 to 40 recorded funnel-web bites every year. This is because the antivenom is an excellently effective treatment – but the new discovery could help tweak it.

“The Newcastle funnel-web, Atrax christenseni— dubbed Big Boy—is a totally new species. The ‘true’ Sydney Funnel-web, Atrax robustus centres on the North Shore of Sydney and the Central Coast, and the Southern Sydney Funnel-web, Atrax montanus, is a resurrected species name from 1914,” Loria explained.

The first person to discover the Aussie spider, Kane Christensen, has warned people not to approach it, citing its massive fangs and glands that produce 'copious amounts of venom'

A larger and more venomous species of one of the world's deadliest spiders has been confirmed by Australian scientists. Nicknamed 'big boy', it can grow up to 9cm (3.54 inches) compared with 5cm (1.97 inches) for the more common Sydney funnel-web.

Scientists at the Australian Museum reported they’ve discovered a new species of spider, and it’s so deadly that just one bite is all it takes to kill a fully-grown adult human.
