Danger to people: DeadlyOne of the most dangerous animals in the world.

🚑 If it bites or stings

Wash the bite and cool it. Get medical help if the pain is strong or the person feels unwell.
In Australia, treat any big black spider bite as a funnel-web bite: Pressure immobilisation: wrap a firm elastic bandage over the bite and then up the whole limb, splint it, and keep the person completely still until help arrives.

Always call your emergency number first (112, 000, 911). This is general first aid guidance, not medical advice. First aid basics

⛑️ Stay safe

Never touch, catch or tease a wild animal, even a small one, and even if it looks asleep or dead.
Give it space. If you meet one, stay calm, step back slowly and let it go its own way.
If one bites or stings you: stay calm, keep still, call your emergency number (112, 000, 911) or get to a hospital fast. Remember what it looked like, a photo helps.

It is not out to get you. It uses its venom to catch food or to protect itself, and it would much rather hide. More about staying safe
