Acacia cultriformis, known as the knife-leaf wattle, dogtooth wattle, half-moon wattle or golden-glow wattle, is a perennial tree or shrub of the genus Acacia native to Australia. It is widely cultivated, and has been found to have naturalised in Asia, Africa, North America, New Zealand and South America. A. cultriformis grows to a height of about 4 m (13 ft) and has triangle-shaped phyllodes. The yellow flowers appear from August to November in its natural range. Its attractive foliage and bright flowers make it a popular garden plant.
Acacia pycnantha, most commonly known as the golden wattle, is a tree of the family Fabaceae native to southeastern Australia. It grows to a height of 8 m (26 ft) and has phyllodes instead of true leaves. Sickle-shaped, these are between 9 and 15 cm long, and 1–3.5 cm wide. The profuse fragrant, golden flowers appear in late winter and spring, followed by long seed pods. Plants are cross-pollinated by several species of honeyeater and thornbill, which visit nectaries on the phyllodes and brush against flowers, transferring pollen between them. An understorey plant in eucalyptus forest, it is found from southern New South Wales and the Australian Capital Territory, through Victoria and into southeastern South Australia.
Acacia cyclops, commonly known as coastal wattle, cyclops wattle, one-eyed wattle, red-eyed wattle, redwreath acacia, western coastal wattle, rooikrans, rooikrans acacia, is a coastal shrub or small tree in the family Fabaceae. Native to Australia, it is distributed along the west coast of Western Australia as far north as Leeman, and along the south coast into South Australia. The Noongar peoples of Western Australia know the plant as wilyawa or woolya wah.
Acacia saligna, commonly known by various names including coojong, golden wreath wattle, orange wattle, blue-leafed wattle, Western Australian golden wattle, and, in Africa, Port Jackson willow, is a small tree in the family Fabaceae. Native to Australia, it is widely distributed throughout the south west corner of Western Australia, extending north as far as the Murchison River, and east to Israelite Bay. The Noongar peoples know the tree as Cujong.
Acacia ligulata is a species of Acacia, a dense shrub widespread in all states of mainland Australia. It is not considered rare or endangered. Its common names include sandhill wattle, umbrella bush, marpoo, dune wattle, small coobah, wirra, and watarrka.
Acacia implexa, commonly known as lightwood or hickory wattle, is a fast-growing Australian tree, the timber of which is used for furniture making. The wood is prized for its finish and strength. The foliage was used to make pulp and dye cloth.
Acacia complanata, known as long-pod wattle and flat-stemmed wattle, is a perennial tree native to eastern Australia.
Acacia decurrens, commonly known as black wattle or early green wattle, is a perennial tree or shrub native to eastern New South Wales, including Sydney, the Greater Blue Mountains Area, the Hunter Region, and south west to the Australian Capital Territory. It grows to a height of 2–15 m (7–50 ft) and it flowers from July to September.
Acacia falcata, commonly known as sickle wattle and by other vernacular names including sally, is a perennial shrub or tree native to eastern Australia, which reaches five metres in height and has cream flowers in early winter. It gets its common and scientific name for its sickle-shaped leaves. Hardy and adaptable to cultivation, it is used in regeneration of bushland.
Acacia fimbriata, commonly known as the fringed wattle or Brisbane golden wattle, is a species of Acacia that is native along much of the east coast of Australia.
Acacia binervia, commonly known as the coast myall, is a wattle native to New South Wales and Victoria. It can grow as a shrub or as a tree reaching 16 m in height. This plant is reportedly toxic to livestock as the foliage (phyllodes) contain a glucoside which can produce hydrogen cyanide if cut.

Trichilogaster is a small genus of chalcid wasps in the family Pteromalidae, subfamily Ormocerinae. With one described exception, they all are Australian species that are gall-formers on Australian species of Acacia. The exception is an Arabian species. Apart from its ecological interest, the genus is of practical importance because some of its members are successful biocontrol agents in South Africa at least, where T. acaciaelongifoliae and T. signiventris have been established successfully to control invasive Australian Acacia species, notably Acacia longifolia and Acacia pycnantha.
Acacia linifolia, known colloquially as white wattle, or flax wattle, is a species of Acacia native to eastern Australia.
Trichilogaster signiventris, commonly known as the golden wattle bud-galling wasp, is a species of Australian chalcid wasps that parasitises, among others, Acacia pycnantha. It has been introduced into South Africa, where the golden wattle has become an invasive pest.
Acacia eremaea is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to an area in western Australia.
Acacia courtii, also commonly known as Northern Brother wattle or North Brother wattle, is a tree belonging to the genus Acacia and the subgenus Juliflorae that is native to eastern Australia. It is currently listed as vulnerable by the Environment Protection and Biodiversity Conservation Act 1999.
