Compared to some other snake species like cobras and vipers, the Eastern Brown has quite short fangs, just about 3mm in length. Even though they may bite a few times if triggered, they inject a very small quantity of venom, roughly 4 mg, but that is enough to kill a human.

Their venom has a subcutaneous LD50 range of 36.5 into 53 μg/kg comprising for the most part of neurotoxins and blood coagulants.The symptoms include collapse, convulsions, nausea, dizziness, renal failure, paralysis and cardiac arrest, and without proper medical treatment, bites can prove deadly.
