The deadliest spiders — or at least those most frequently cited as having caused death or serious injury to humans — are funnel-web spiders (Atrax), redback and black widow spiders (Latrodectus), banana and wandering spiders (Phoneutria) and recluse spiders (Loxosceles).
The Australian funnel-web spiders are among the deadliest spiders in the world in the effect their bites have on humans and our primate relations (although the bite has little effect on dogs and cats). There are many species of funnel-web spiders in Australia but only male Sydney Funnel-webs have caused human deaths.
One land-dwelling animal that has the history to back up those claims is the funnel-web spider – with venom that can kill a human in just 15 minutes.
The Sydney funnelweb spider Atrax robustus, is considered to be the world's most dangerous spider. It is found within a 100 km diameter circle around Sydney. No deaths have occurred since the advent of an antivenom in 1981. Males wander at night in spring and summer in search of females.
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
When threatened or provoked, funnel-web spiders will display aggressive behaviour, rearing up on their hind legs and displaying their fangs.

Brazilian wandering spiders
It has a highly toxic venom and is regarded (along with the Australian funnel-web spiders) as among the most dangerous spiders in the world.
All funnel-web spider bites should be treated as potentially life-threatening, even though only approximately 10% to 15% of bites are venomous. Since the venom from the funnel-web spider bite is highly toxic, all species should be considered potentially dangerous.
The Sydney funnel web spider is considered the most venomous spider in the world. A large, bulky spider, with females reaching over 35mm in body length and males around 25mm.

Tarantula toxicity is a rare occurrence. There are over 900 species of tarantula, and they are popular as pets. While tarantulas do possess venom, the vast majority of tarantula-related injuries occur as a result of urticating hairs.

Unfortunately this is not true. A Daddy-long-legs Spider can give a small bite, although it is very unlikely to happen.
Granddaddy long legs are typically harmless to humans but can become bothersome if they congregate in large numbers. If they aren't causing a problem, it is best to leave them alone.
The daddy long-legs is originally from subtropical Asia but, having accompanied humans in their global spread, the species is now found throughout the world in warm locations, including across Australia. In fact, it's now one of Australia's most common spider species.
"Huntsmen are super fast but they get confused, so if a huntsman is running towards you, it's confused. They're not aggressive spiders at all and they generally stay high up because that's where they're finding the food they want to eat."

Huntsman spiders are large, long-legged spiders. They are mostly grey to brown, sometimes with banded legs. Many huntsman spiders, especially Delena (the flattest), and including Isopeda, Isopedella and Holconia, have rather flattened bodies adapted for living in narrow spaces under loose bark or rock crevices.
Researchers in Australia discovered a rare, giant species of trapdoor spider found only in Central Queensland. Its name, Euoplos dignitas, comes from the Latin word meaning dignity or greatness, "reflecting the impressive size and nature of the spider," the Queensland Museum said in a statement.
According to 9News, the newly discovered species, a blind daddy long-legs spider, was located in boreholes in Western Australia's dry Pilbara region. It's the first cave-adapted daddy long-legs to be reported on the continent, with other blind species of this genus previously only having been found in Southeast Asia.
Generally, spiders want to avoid humans and will only bite as a defense mechanism if they are provoked. Many are extraordinary at hiding or camouflaging themselves because they don't want to be seen.
