Australia is home to one of the most diverse and remarkable spider faunas on the planet, with an estimated 10,000 species ranging across every habitat from tropical rainforest to scorching desert. The continent’s long geological isolation has allowed spider lineages to evolve in unique directions, producing forms and behaviors found nowhere else on earth. From the tiny, dancing peacock spider to the massive whistling tarantula, the range of size, color, and lifestyle is extraordinary.
Australia has a disproportionate reputation for deadly spiders, and while it does host genuinely dangerous species like the Sydney funnel-web and redback, the vast majority of its spiders are completely harmless to humans. The development of antivenom for both major venomous species has meant that no confirmed spider-related death has been recorded in Australia since 1979. Most bites that do occur happen when spiders are accidentally disturbed or trapped against skin, as spiders have no interest in seeking out humans.
Australian spiders occupy every ecological niche imaginable. Some are dedicated burrowers, spending their entire lives underground in silk-lined tunnels. Others are canopy hunters, bark camouflagers, water-surface predators, or chemical mimics that lure moths with fake pheromones. This ecological diversity reflects millions of years of adaptation to Australia’s enormously varied landscapes, from the wet tropics of Queensland to the dry plains of the interior.
Spiders play an indispensable role in Australian ecosystems, acting as one of the primary controllers of insect populations across agricultural land, forests, and urban gardens. Many species are still being discovered and described by scientists, particularly small jumping spiders and trapdoor species in remote regions. The peacock spider alone has gone from a handful of known species to over 90 described species in just the past fifteen years, suggesting that Australia’s full spider diversity is still far from fully understood.
Spider Found In Australia
Sydney Funnel-Web Spider (Atrax robustus)
Widely regarded as one of the most dangerous spiders in the world, the Sydney funnel-web is found in and around Sydney and nearby regions of New South Wales. It builds funnel-shaped silk retreats in moist, sheltered ground and is aggressive when threatened, rearing up and striking repeatedly. Its venom contains a compound called atracotoxin that is highly toxic to primates, and before antivenom was developed in 1981, it was responsible for several human deaths.
Redback Spider (Latrodectus hasselti)
One of Australia’s most recognized spiders, the redback is found across the entire continent including urban areas, gardens, and outhouses. The female is distinctive with her black body and vivid red or orange stripe on the abdomen. Its venom causes a painful syndrome called latrodectism, with symptoms including sweating, nausea, and intense pain, though deaths are now extremely rare thanks to widely available antivenom.
White-Tailed Spider (Lampona cylindrata)
A common visitor inside Australian homes, the white-tailed spider is a slender, dark spider with a distinctive white spot at the tip of its abdomen. It is a hunter rather than a web-builder, actively seeking out other spiders — particularly black house spiders — as its preferred prey. Bites were once blamed for causing flesh-eating ulcers, but scientific studies have found no direct evidence to support this claim.
Huntsman Spider (Heteropoda venatoria and related species)
Australia has an extraordinary diversity of huntsman spiders, with over 150 native species. They are large, fast, and flat-bodied, built for life under bark and in rock crevices. Despite their alarming size — leg spans can exceed 15 cm — they are not considered dangerous to humans. They are actually welcomed by many Australians as natural pest controllers, hunting cockroaches and other insects inside homes.
Mouse Spider (Missulena spp.)
Named for their stout, mouse-like bodies, mouse spiders are found across Australia in a variety of habitats from coastal areas to arid inland regions. Males are often brightly colored with red or blue markings and wander in search of females, especially after rain. Their venom is potentially as toxic as that of funnel-web spiders, though they are generally less aggressive and envenomation is less common in practice.
Trapdoor Spider (Idiopidae and related families)
Trapdoor spiders are found throughout Australia and are masters of ambush, constructing silk-lined burrows sealed with a hinged door made of soil and silk. They wait just inside the door, sensing vibrations, then burst out to grab passing prey with remarkable speed. Several species are long-lived, with some females recorded living for over 40 years, making them among the longest-lived spiders on earth.
Black House Spider (Badumna insignis)
Extremely common across southeastern Australia, the black house spider builds messy, funnel-shaped webs in window frames, wall crevices, and under bark. It is dark brown to black and has a robust build. While its bite can cause local pain, nausea, and sweating, it is not considered medically serious. It is frequently confused with the far more dangerous funnel-web spider by nervous homeowners.
Garden Orb-Weaver (Eriophora transmarina)
One of the most commonly encountered spiders in Australian gardens, the garden orb-weaver builds large, classic circular webs between shrubs and fences at dusk, retreating to a hiding spot by day. It is plump, brown, and variable in color, and completely harmless to humans. On warm evenings its webs can be found strung across pathways and garden beds across the eastern and southern states.
St. Andrew’s Cross Spider (Argiope keyserlingi)
Named for the distinctive X-shaped band of zigzag silk it weaves through the center of its web — resembling the cross of St. Andrew — this colorful spider is found across eastern and southern Australia. The silk cross, known as a stabilimentum, is thought to attract insects by reflecting ultraviolet light. Females are strikingly banded in yellow, black, and silver, while males are much smaller and less conspicuous.
Net-Casting Spider (Deinopis subrufa)
Also called the ogre-faced spider for its enormous forward-facing eyes, the net-casting spider holds a small rectangular web between its front legs and lunges forward to throw it over passing prey. Its massive eyes are extraordinarily light-sensitive, allowing it to hunt effectively in near-total darkness. It is found across eastern Australia and is one of the most behaviorally unique spiders on the continent.
Wrap-Around Spider (Dolophones turrigera)
This remarkable Australian spider has a concave underside that allows it to press itself flush against a tree branch, becoming almost perfectly camouflaged as part of the bark. By day it rests motionless in this wrapped position, and by night it constructs an orb web nearby. It is completely harmless and represents one of the most extraordinary examples of camouflage adaptation in the spider world.
Bolas Spider (Ordgarius magnificus)
One of Australia’s most unusual hunters, the bolas spider does not build a conventional web. Instead, it produces a sticky ball of silk on a line laced with chemicals that mimic female moth pheromones. It swings this ball to snare male moths attracted by the scent. Found in eastern Australia, it is a master of chemical deception and a fascinating example of highly specialized predatory behavior.
Lace-Web Spider (Badumna longinqua)
Closely related to the black house spider, the lace-web spider is found across Australia and has been accidentally introduced to New Zealand, Europe, and parts of North America through plant trade. It builds tangled, lacy webs in foliage and around building exteriors. It is a hardy, adaptable species and generally docile, posing minimal risk to humans despite being one of the more frequently encountered spiders in urban gardens.
Two-Tailed Spider (Hersilia spp.)
These slender, bark-patterned spiders are found on tree trunks across northern and eastern Australia. Their two dramatically elongated spinnerets give them a distinctive silhouette, and they are superbly camouflaged against rough bark. When approached by a predator, they run rapidly around the trunk to keep to the opposite side. They lay radiating silk lines on the bark surface to detect and trap wandering insects.
Peacock Spider (Maratus spp.)
One of Australia’s most celebrated spider discoveries in recent decades, peacock spiders are tiny jumping spiders — barely a few millimeters long — in which males have evolved breathtaking iridescent abdominal flaps used in elaborate courtship dances. Over 90 species have been described, most discovered since 2010, and new species continue to be found regularly. They are found across much of Australia and are completely harmless.
Whistling Spider (Selenocosmia crassipes)
Australia’s largest spider, the whistling (or barking) tarantula is found in Queensland’s arid and semi-arid regions. It can reach a body length of 6 cm and a leg span of 16 cm. When threatened, it produces an audible hissing sound by rubbing its mouthparts together. Its burrows can be 1–2 meters deep, and while its venom can cause significant illness in dogs, it poses a lesser threat to healthy adult humans.
Flower Spider (Thomisus spectabilis)
A classic ambush predator, the flower spider waits motionless inside white or yellow flowers across eastern and southern Australia, perfectly matching the petals. It grabs visiting bees and insects with its powerful front legs, subduing them with venom. Despite feeding regularly on insects much larger than itself, it is entirely harmless to humans and is a charming and commonly observed garden spider.
Long-Bellied Spider (Tetragnatha spp.)
These elongated, long-legged spiders are found near water across Australia, building horizontal orb webs in low vegetation over streams and wetlands. Their extraordinarily slender bodies and stretched-out posture make them nearly invisible when resting along a grass stem or reed. They are excellent swimmers if they fall into water and are completely harmless, feeding mainly on small aquatic insects.
Lichen Huntsman (Pandercetes gracilis)
Found in the rainforests of Queensland and extending into Southeast Asia, the lichen huntsman is one of Australia’s most beautifully camouflaged spiders. Its body is intricately patterned to mimic the lichen and moss of rainforest tree bark, and it presses itself completely flat against surfaces to eliminate its shadow. It is harmless to humans and rarely seen despite being present in suitable habitat.
Jewel Spider (Austracantha minax)
Also called the Christmas spider because it is most visible during the Australian summer holiday season, the jewel spider is a small, striking orb-weaver with a white or yellow abdomen decorated with black markings and six distinctive spines. It builds webs in shrubs and low trees across southern and eastern Australia, often in large communal groups. It is harmless to humans and one of the most photographed spiders on the continent.
Daddy Long-Legs (Pholcus phalangioides)
Ubiquitous in Australian homes, daddy long-legs spiders build loose, tangled webs in corners, cupboards, and undisturbed spaces. Despite a persistent myth claiming they are the most venomous spiders in the world but lack fangs long enough to bite humans, both parts of this claim are false — their fangs can penetrate skin and their venom is not medically significant. They are actually beneficial, often consuming other spiders including redbacks.
Brown Trapdoor Spider (Misgolas spp.)
Frequently confused with the more dangerous funnel-web spider, the brown trapdoor spider is found in eastern Australia and builds a simple burrow without a true hinged lid. It is much calmer in temperament than funnel-webs and far less dangerous, though its bite can still cause local pain and swelling. Females rarely leave their burrows, while males wander in search of mates during warmer months.
Golden Silk Orb-Weaver (Trichonephila edulis)
Australia’s native golden silk orb-weaver is a large, impressive spider found across northern and eastern Australia. Females are dramatically larger than males and spin enormous webs of golden-tinted silk between trees. The silk is extraordinarily strong and has long attracted scientific interest for potential applications in materials science. It feeds on large insects and occasionally small vertebrates that become entangled in its web.
Spiny Spider (Gasteracantha spp.)
Australia has several native species of spiny spiders, characterized by their hard, brightly colored abdomens armed with pointed spines. They build neat orb webs in gardens and forest edges and are most visible in summer. The spines are thought to make them difficult for birds to swallow. They are entirely harmless to humans and are among the more distinctive and easily identified of Australian garden spiders.
Comb-Footed Spider (Achaearanea spp.)
These small, round-bodied spiders build tangled cobwebs in sheltered spots across Australia — under rocks, in leaf litter, and around the bases of plants. The “comb foot” refers to specialized hairs on their hind legs used to fling silk over prey. While related to widow spiders, Australian species are generally not considered medically significant and are among the least noticed but most abundant spiders in the country.
Six-Eyed Sand Spider (Sicarius spp.)
Found in the arid interior of Australia, this flattened, sand-colored spider buries itself just below the surface of loose sand, with only its eyes exposed, waiting for insects to wander within reach. Its venom is considered potentially dangerous, containing enzymes that can destroy tissue, though documented bites on humans in Australia are essentially nonexistent. It is one of the more secretive and rarely encountered of Australia’s venomous spiders.
Sac Spider (Clubiona spp.)
Sac spiders are widespread across Australia in grasslands, shrublands, and forests. They construct small silken retreats — the characteristic sac — inside rolled leaves or under bark, emerging at night to hunt. They are slender, pale to mid-brown spiders and are among the most common spiders in agricultural settings. Bites occasionally cause localized pain and redness but are not considered medically serious.
Jumping Spider (Opisthoncus spp.)
Australia is home to hundreds of jumping spider species, and Opisthoncus is one of the most diverse native genera. These small, alert, big-eyed spiders are active daytime hunters found on fences, walls, foliage, and bark across the country. Their excellent vision, curious behavior, and tendency to turn and face observers have made them favorites among spider enthusiasts and photographers alike.
Rainforest Huntsman (Holconia spp.)
Several large huntsman species inhabit the rainforests of Queensland and New South Wales, living under bark and in tree hollows in wetter forest environments. They are among the largest huntsman spiders in Australia, with impressive leg spans and rapid movement. Like other huntsmans they are harmless to humans despite their size and are important predators of cockroaches, moths, and other forest insects.
Water Spider (Dolomedes spp.)
Fishing or water spiders are found along streams, ponds, and wetlands across eastern and southern Australia. They rest on the water surface, detecting vibrations made by struggling insects or small fish, then dash across the surface to catch them. They are capable of diving briefly underwater to escape predators. Despite their size and dramatic hunting behavior, they are harmless to humans.
Eastern Mouse Spider (Missulena bradleyi)
Found in eastern Australia from Queensland down through New South Wales and into Victoria, the eastern mouse spider is a robust, ground-dwelling species that constructs deep burrows with soft, silken entrances rather than a hard trapdoor. The male is one of Australia’s most strikingly colored spiders, with a vivid red head and bright blue-black abdomen. Its venom is considered potentially as dangerous as that of the Sydney funnel-web, yet documented serious envenomations are surprisingly rare, possibly because the spider often delivers dry bites. Males are most commonly encountered wandering in search of females during daylight hours after rainfall, which frequently brings them into contact with humans in suburban gardens and parklands.
Scorpion-Tailed Spider (Arachnura melanura)
This extraordinary orb-weaver from eastern Australia has a long, curling tail-like extension on its abdomen that resembles a scorpion’s tail. It is thought to mimic dead plant material or debris hanging in vegetation. Females are much larger than males and spin small orb webs in shrubs and low trees. It is entirely harmless and one of the more bizarre-looking of Australia’s many eccentric spider species.
Bird-Dropping Spider (Celaenia excavata)
Found across eastern Australia, the bird-dropping spider has evolved a masterful disguise — its body is patterned in white, brown, and black to look exactly like a fresh bird dropping on a leaf. It does not build a web to catch prey; instead, like the bolas spider, it releases chemicals mimicking moth pheromones to lure male moths directly to it at night. It is completely harmless to humans.
Triangulate Cobweb Spider (Steatoda triangulosa)
A relative of the redback, this small, dark spider builds untidy cobwebs in sheltered corners of homes, sheds, and garden structures across Australia. It is far less venomous than its notorious cousin and bites are generally of little medical concern. It is actually useful in homes as it readily preys on other spiders, including redbacks, making it an inadvertent ally for households trying to reduce spider numbers.
Brush-Footed Trapdoor Spider (Idiommata spp.)
Found in Western Australia and parts of South Australia, brush-footed trapdoor spiders are medium-sized burrowing spiders with distinctive tufts of hair on their feet. They are less well-known than eastern Australian trapdoor species but are equally fascinating in their burrowing behavior and patient ambush hunting style. They are not considered dangerous to humans and are rarely encountered outside their native range.
Tree Funnel-Web Spider (Hadronyche formidabilis)
Found in the rainforests and wet forests of northern New South Wales and Queensland, the tree funnel-web is one of the largest funnel-web species, with females reaching up to 5 cm in body length. Unlike the ground-dwelling Sydney funnel-web, it builds its silk-lined retreat in tree hollows and under bark well above the ground. It is considered medically significant and should be treated with the same caution as other funnel-web species.
Lynx Spider (Oxyopes spp.)
Lynx spiders are agile, long-legged hunters found on grass, shrubs, and low vegetation across Australia. They are named for their cat-like ability to leap onto prey with precision. Their legs are armed with long spines that help them grip struggling insects. They are active daytime hunters with good eyesight and are entirely harmless to humans, playing a valuable role in controlling pest insects in agricultural areas.
Wolf Spider (Lycosa spp.)
Wolf spiders are among the most widespread and commonly seen spiders across Australia, found in grasslands, gardens, forests, and coastal dunes. They are ground hunters, running down prey rather than trapping it in webs, and carry their egg sac attached to their spinnerets and their spiderlings on their back after hatching. While their bite can cause local pain and swelling, they are not considered seriously dangerous to healthy adults.
Grass Spider (Agelenidae relatives)
Several Australian grass spider species build flat, sheet-like webs low in grass and ground cover across southern and eastern Australia. The web has a small funnel retreat at one end where the spider waits. Insects land on the sheet, trip, and fall into the funnel. They are small, brown, and inconspicuous, and pose no threat to humans whatsoever, being among the most ecologically abundant and least noticed of Australia’s many spider groups.
Magnificent Spider (Ordgarius magnificus)
Also one of Australia’s bolas spiders, the magnificent spider is found in Queensland and New South Wales and is notable for the large, knobbed, warty appearance of the female’s abdomen. Like other bolas spiders it uses chemical mimicry to lure moths rather than building a traditional web. It is cryptically colored and extremely difficult to spot in its natural habitat, spending the day motionless on a twig, resembling a bud or piece of bark.
