Treatment of arachnid poisoning in Australia.

Most Australian spiders are capable of causing bites that produce some degree of local injury and occasionally systemic effects. To date, only the Sydney funnel-web spider, which is limited to an area with a 160 kilometre radius from the centre of Sydney, and the female red-back spider, which is found in all states, have been documented as causing deaths. The evidence is mounting that various other species must be considered potentially dangerous.
