Sydney funnel-web : With highly toxic venom produced in large amounts and large fangs to inject it, the Sydney funnel-web is without a doubt the deadliest spider in Australia, and possibly the world.
Other funnel-webs : There are about 40 species of funnel-web spiders in Australia, but only six have been reported to cause severe envenomation, with victims generally around southern Queensland and northern New South Wales.
Redback spiders : These are found throughout Australia, in many habitats, including urban areas. They often hide in dry, sheltered places such as garden sheds, mailboxes and under toilet seats.
Mouse spider : There are eight species of mouse spider found all across Australia and they're typically found in burrows, often near rivers or waterways, and can occasionally be found in suburban areas.
