Overview

Envenomation can come from snakes, spiders, marine stingers, insects, and other animals. First aid depends on the species and setting, so call for expert advice early when unsure.

Snake Bite

Suspected snake bite is a medical emergency.

  • Follow DRSABCD.
  • Call 000.
  • Keep the person still and lying down.
  • Apply a pressure immobilisation bandage over the bite area and along the limb if trained and available.
  • Splint the limb to reduce movement.
  • Mark the bite site on the bandage if known.
  • Do not wash the bite, as venom traces can help identification.

Do not cut, suck, wash, apply ice, or use a tourniquet.

Spider Bite

Spider First Aid
Funnel-web or suspected funnel-web Pressure immobilisation, keep still, call 000
Redback Apply ice packs for pain and seek medical advice
Unknown spider with severe symptoms Call 000 or Poisons Information

Watch for severe pain, sweating, nausea, breathing difficulty, weakness, or collapse.

Jellyfish and Marine Stings

Treatment varies by species and region:

  • In tropical northern Australian waters, apply vinegar for suspected box jellyfish or Irukandji stings and call 000.
  • For bluebottle stings, rinse with seawater, remove tentacles carefully, and use hot water immersion if available and safe.
  • Do not rinse marine stings with fresh water unless specifically advised for that species.
  • Call 000 for breathing difficulty, collapse, severe pain, or suspected Irukandji or box jellyfish.

When Unsure

Call the Poisons Information Centre on 13 11 26 or 000 for urgent symptoms. Keep the person still, monitor breathing and responsiveness, and be ready to start CPR.
