VENOM TOXICITY - the bite of Daddy long-legs spider is not considered dangerous to human health. They are a non-aggressive group of spiders; their fangs very small but may pierce human skin. Area of distribution - Australia-wide.
They do not have venom glands, fangs or any other mechanism for chemically subduing their food. Therefore, they do not have injectable toxins. Some have defensive secretions that might be toxic to small animals if ingested.
Daddy long legs, also known as cellar spiders, contain venom and possess fangs, but there has been no evidence of their fangs being too short to cut through human skin or of their venoms being deadly and poisonous to humans. In reality, daddy long legs are not poisonous or dangerous to humans and are not known to bite.
Although the daddy-long-legs is one of Australia's most common and frequently seen spiders, it isn't native to Australia and was accidentally introduced to this country from Europe many years ago.
You could even say that daddy longlegs are one of the most benign insects around. They don't bite or poison anyone, and they are not garden or farm pests. They are just gentle, gawky bugs that like nothing better than meeting up together and having a communal gathering.
Because the “daddy longlegs” eats pests, it can be considered beneficial, but when enough beneficial arachnids get together, they become a nuisance. You should sweep them away with a broom, and look for other pests that may have attracted them in the first place.

In summary, on current evidence the most dangerous spiders in the world are funnel-web spiders (Atrax and Hadronyche species), Redback Spiders and their relations (Latrodectus species), Banana Spiders (Phoneutria species) and Recluse Spiders (Loxosceles species).
Banana spiders may look intimidating, but they're actually timid and not considered dangerous. Though they aren't poisonous, their bite can be painful.

Sometimes when we get too close or disturb them, they treat us like they would treat any predator. Many spiders have threat displays intended to scare off predators, such as rearing up or lunging. Biting in self-defence is another strategy that spiders can use when they are afraid for their lives.

Despite the rumors, daddy longlegs are not venomous and do not bite humans. However, they are hunters and come out at night to catch their prey.
Yet despite their apparent harmlessness, Daddy-long-legs have little trouble catching, wrapping and killing much larger Huntsman spiders. They have even been known to catch Redback spiders and Funnel-web spiders, both of which are far larger and more toxic than the Daddy-long-legs.
