What is the deadliest spider in Australia?

Atracinae, commonly known as Australian funnel-web spiders, is a subfamily of spiders in the funnel-web spider family Hexathelidae.

Atracinae consists of three genera: Atrax, Hadronyche, and Illawarra.

The subfamily includes species with medically significant venom, six species of which have severely envenomed human victims.

The bite of the Sydney funnel-web spider (Atrax robustus) is potentially deadly, but there have been no fatalities since the introduction of modern first aid techniques and antivenom.

The subfamily contains 35 species.

All members of the subfamily are native to Australia.
