The causative snake species, their venoms and envenoming apparatus, and the epidemiology, clinical profile, and management of envenomed humans is discussed. Australian snakes dangerous to man are elapids, in five groups corresponding to available monovalent antivenoms. The principle systemic effects of their venoms comprise neurotoxicity (N), defibrination type coagulopathy (C), myotoxicity (M), and renal damage (R), the latter possibly secondary in many cases. Major local effects of bites are not usually seen, but some groups commonly cause local edema (E). The groups are: (1) Brown snakes (Pseudonaja) = C,R,N; (2) Tiger snakes (Notechis, Tropidechis, Austrelaps) = N,C,M,R,E; (3) Mulga snakes (Pseudechis) = M,R,E; (4) Death adders (Acanthophis) = N; Taipans (Oxyuranus) = N,C,M,R,E. Dry bites are common; Australian deaths from snakebites are approximately 1-2 per year. Bites with significant envenomation need rapid expert care and appreciation of common venom pathology profiles. Antivenom, preferably monovalent, is the mainstay of treatment in such cases. Venom detection kits allow identification of the causative snake and appropriate antivenom. Subcutaneous pretesting for antivenom allergy is an unacceptable practice in Australia.
