How Dangerous Are Australian Venomous Snakes?
Most Australian venomous snakes avoid humans and will only bite if threatened or trapped. Fatalities are rare today due to improved antivenoms and medical care. The eastern brown snake is responsible for most recorded fatalities, mainly because it lives close to populated areas and is easily disturbed.
What to Do If You Encounter a Venomous Snake
- Remain calm and still; most snakes will move away if undisturbed.
- Do not attempt to catch or kill the snake.
- If bitten, apply a pressure immobilization bandage and call emergency services immediately.
