Redback spiders are the most dangerous spider in Australia and frequently kill people.
While redbacks are medically significant, they haven't caused a confirmed death in Australia since antivenom was developed in 1956, over 70 years ago. Sydney funnel-web spiders are the actual apex predator among Australian arachnids, with venom far more dangerous to humans. Redbacks became iconic in Australian culture and media, possibly because they're more commonly encountered around homes and their distinctive appearance makes them memorable. The overstatement of redback danger reflects how Australia's dangerous-fauna reputation becomes simplified in popular imagination.
