Generally, a redback is fairly unpleasant, but doesn't require a trip to the hospital (for a healthy adult), so its unlikely to be fatal in most cases anyway (thankfully!).

Funnel-webs are terrifying.

A redback bite generally requires medical attention; though not triple-0 level urgency, it shouldn't be a wait-and-see-how-you-feel treatment.

Unless you're a kid, and then even the antidote is terrifying.
