Austracantha is a genus of spider with a single species, Austracantha minax, commonly known as the jewel spider or the Christmas spider. It is a member of the family Araneidae and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around 12 mm (0.47 in) for females, and 5 mm (0.20 in) for males. Their abdomen has six distinctive projections ("spines") that makes them easy to identify. They are predominantly a shiny black, with variable white, yellow, and orange patterns. Melanistic forms also occur during autumn. They are facultatively gregarious, and can be found in large aggregations of overlapping orb webs. They feed on small flying insects that get entangled in their webs. They are harmless to humans, though the webs can be a nuisance for bushwalkers. They are most abundant during the summer months.
Steatoda grossa, commonly known as the cupboard spider, the dark comb-footed spider, the brown house spider, or the false widow or false black widow, is a common species of spider in the genus Steatoda.
The black house spider or common black spider is a common species of cribellate Australian spider, introduced to New Zealand and Japan. A closely related species, Badumna longinqua, the grey house spider, has a similar distribution, but has also been introduced to the Americas.

Uloborus plumipes is a species of Old World cribellate spider in the family Uloboridae. Common names include the feather-legged lace weaver and the garden centre spider, the latter name being due to its frequent occurrence of this spider in garden centres. The species name is derived from the Latin pluma "feather" and pes "foot".
The pink robin is a small passerine bird native to southeastern Australia. Its natural habitats are cool temperate forests of far southeastern Australia. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 13.5 cm (5.3 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive white forehead spot and pink breast, with grey-black upperparts, wings and tail. The belly is white. The female has grey-brown plumage. The position of the pink robin and its Australian relatives on the passerine family tree is unclear; the Petroicidae are not closely related to either the European or American robins, but appear to be an early offshoot of the Passerida group of songbirds.
The rose robin is a small passerine bird native to Australia. Like many brightly coloured robins of the Petroicidae, it is sexually dimorphic. The male has a distinctive pink breast. Its upperparts are dark grey with white frons, and its tail black with white tips. The underparts and shoulder are white. The female is an undistinguished grey-brown.

Metepeira labyrinthea, the labyrinth orbweaver, is a spider, with thin legs and a round, bulbous abdomen It is a member of the genus Metepeira in the family Araneidae. The female’s length is 5.3 mm, its carapace 2.3 mm, abdomen 3.3 mm, and extended legs 18.4 mm. The carapace is brown or gray, and the abdomen is dark with a white pattern.

The male spider is three-quarters of the female’s length, or slightly larger, with a darker carapace and with greater contrast between dark and light areas of the legs. Metepeira are easily distinguished from other Araneidae by their light eye region, white median line on the sternum, relative length of the leg segments, small male palpus, weakly sclerotized epigyne and the special composite web.
Arkys lancearius, the triangular spider, is a common Australian spider belonging to the family Arkyidae. It is an ambush hunter, commonly found resting on leaves and ferns or hanging from just a few threads of silk. The front two pairs of legs are large, suited for grabbing small insects, while the rear pairs of legs are much smaller.
Ariamnes colubrinus, known as the whip spider, is a common Australian spider belonging to the family Theridiidae. It is found in Victoria, New South Wales and Queensland.
Poecilopachys australasia, commonly known as the two-spined spider, is an Australian orb-weaving spider which has also been recorded in New Zealand since the early 1970s. The spider is nocturnal, spinning a cart-wheel-shaped web at night which it consumes in the morning. Females can be commonly found on the undersides of citrus tree leaves during the day.
Cyrtophora exanthematica are tent spiders common in tropical Asia and Australia. They are commonly known as double-tailed tent spiders because of the pair of blunt projections at the end of their abdomens. They are harmless to humans.
Nicodamus peregrinus, known as the red and black spider, is a spider found in eastern and southern Australia. Unlike the redback spider, the bright red coloration does not appear to warn of significant danger to humans. Food is a variety of small insects. They have been recorded in Queensland, New South Wales, Victoria and South Australia.
Philodromus aureolus, the wandering crab spider, is a mainly European running crab spider of the family Philodromidae. The taxonomy of the species group named after Philodromus aureolus is in a state of flux and a number of new species have recently been recognised.
Stephanopis altifrons is a crab spider found in Australia. A cryptic species often hidden on bark of a tree. The body length of the female is up to 10 mm, the male 6 mm. The colour is usually brown, or shades of grey, sometimes black. The egg sac is 7.5 mm in diameter. Often placed in a crevice in tree bark; irregular in shape and camouflaged with debris. Eggs are off white in colour, 25 to 30 in number. The female rests with the eggs. The food of this spider appears to be other spiders. Recorded prey include spiders in the families Salticidae and Hersiliidae.
Cyrtophora hirta is a species of tent spider found in the Australia. The southern range of distribution is near Sydney, though there are New Guinea and Tasmanian records on the Atlas of Living Australia. Ludwig Koch described the species in 1872 from specimens from Bowen, Queensland.
Euryopis splendens is a species of comb-footed spider in the family Theridiidae. The range of distribution is the south east of Australia. The spider lives under stones or bark.

The grey coloured spherical egg sac is around 6 mm in diameter, carried by the female. Eggs are 45 to 60 in number, 0.8 mm in diameter. Prey is ground dwelling insects. The spider has been identified as occurring in Queensland, New South Wales, and Victoria.
