Kangaroo in the context of Kangaroo rat

The red kangaroo (Osphranter rufus) is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial. It is found across mainland Australia, except for the more fertile areas, such as southern Western Australia, the eastern and southeastern coasts, and the rainforests along the northern coast.

Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping and other gaits where the entire body is temporarily airborne by the relatively long duration of the aerial phase and high angle of initial launch.

Some animals, such as the kangaroo, employ jumping (commonly called hopping in this instance) as their primary form of an locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump and show jumping.

Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, the quokka, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands. As of 2025 there are 63 recognised living species in this family.

The 1982 Commonwealth Games were held in Brisbane, Australia, from 30 September to 9 October 1982. The Opening Ceremony was held at the QEII Stadium (named after Elizabeth II), in the Brisbane suburb of Nathan. The QEII Stadium was also the athletics and archery events venue. Other events were held at the purpose-built Sleeman Sports Complex in Chandler.

The Chairman of the 1982 Commonwealth Games was Sir Edward Williams. The 1982 Commonwealth Games Logo was designed by Hugh Edwards. The symbol is derived from the form of a bounding kangaroo. The three bands, forming stylized A's (for Australia), and is in colours which are common to flags of many Commonwealth countries.

Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen.

Extant marsupials encompass many species, including kangaroos, koalas, opossums, possums, Tasmanian devils, wombats, wallabies, and bandicoots.

Carrion (from Latin caro 'meat'), also known as a carcass, is the decaying flesh of dead animals. Carrion may be of natural or anthropic origin (e.g. wildlife, human remains, livestock), and enters the food chain via different routes (e.g. animals dying of disease or malnutrition, predators and hunters discarding parts of their prey, collisions with automobiles).

Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eating animals include vultures, eagles, hyenas, Virginia opossum, Tasmanian devils, and coyotes. Many invertebrates, for example carrion beetles, burying beetles, blow-fly maggots, and flesh-fly maggots, also eat carrion. All of these animals, together with microbial decomposers, help to recycle nitrogen and carbon in animal remains.

Deciduous teeth or primary teeth, also informally known as baby teeth, milk teeth, or temporary teeth, are the first set of teeth in the growth and development of humans and other diphyodonts, which include most mammals but not elephants, kangaroos, or manatees, which are polyphyodonts. Deciduous teeth develop during the embryonic stage of development and erupt (break through the gums and become visible in the mouth) during infancy. They are usually lost and replaced by permanent teeth, but in the absence of their permanent replacements, they can remain functional for many years into adulthood.

A wallaby (/ˈwɒləbi/) is a small or middle-sized macropod native to Australia and New Guinea, with introduced populations in New Zealand, Hawaii, the United Kingdom and other countries. They belong to the same taxonomic family as kangaroos and sometimes the same genus, but kangaroos are specifically categorised into the four largest species of the family. The term "wallaby" is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise.

There are nine species (eight extant and one extinct) of the brush wallaby (genus Notamacropus). Their head and body length is 45 to 105 cm (18 to 41 in) and the tail is 33 to 75 cm (13 to 30 in) long. The 19 known species of rock-wallabies (genus Petrogale) live among rocks, usually near water; two species in this genus are endangered. The two living species of hare-wallabies (genus Lagorchestes; two other species in this genus are extinct) are small animals that have the movements and some of the habits of hares. The three species (two extant and one extinct) of nail-tail wallabies (genus Onychogalea) have one notable feature: a horny spur at the tip of the tail; its function is unknown. The seven species of pademelons or scrub wallabies (genus Thylogale) of New Guinea, the Bismarck Archipelago, and Tasmania are small and stocky, with short hind limbs and pointed noses. The swamp wallaby (genus Wallabia) is the only species in its genus.Another wallaby that is monotypic is the quokka or short-tailed scrub wallaby (genus Setonix); this species is now restricted to two offshore islands of Western Australia which are free of introduced predators. The seven species of dorcopsises or forest wallabies (genera Dorcopsis (four species, with a fifth as yet undescribed) and Dorcopsulus (two species)) are all native to the island of New Guinea.

Wallaroo /wɒləˈruː/ is a common name for several species of moderately large macropods, intermediate in size between the kangaroos and the wallabies, that are native to Australia and Papua New Guinea. The word "wallaroo" is from the Dharug walaru with spelling influenced by the words "kangaroo" and "wallaby".

Pademelons (/ˈpædimɛlən/) are small marsupials in the genus Thylogale, found in Australia, New Guinea, and surrounding islands. They are some of the smallest members of the macropod family, which includes the similar-looking but larger kangaroos and wallabies. Pademelons are distinguished by their small size and their short, thick, and sparsely haired tails. Like other marsupials, they carry their young in a pouch.

The quokka (/ˈkwɒkə/; Setonix brachyurus) is a small macropod about the size of a domestic cat. It is the only member of the genus Setonix. Like other marsupials in the macropod family (such as kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal.

The quokka's range is a small area of southwestern Australia. They inhabit some smaller islands off the coast of Western Australia, particularly Rottnest Island just off Perth and Bald Island near Albany. Isolated, scattered populations also exist in forest and coastal heath between Perth and Albany. A small colony inhabits a protected area of Two Peoples Bay Nature Reserve, where they co-exist with the critically endangered Gilbert's potoroo.

The Macropodiformes (/mækroʊˈpɒdɪfɔːrmiːz/), also known as macropods, are one of the three suborders of the large marsupial order Diprotodontia. They may in fact be nested within one of the suborders, Phalangeriformes. Kangaroos, wallabies and allies, bettongs, potoroos and rat kangaroos are all members of this suborder.

Aggressive mimicry is a form of mimicry in which predators, parasites, or parasitoids share similar signals, using a harmless model, allowing them to avoid being correctly identified by their prey or host. Zoologists have repeatedly compared this strategy to a wolf in sheep's clothing. In its broadest sense, aggressive mimicry could include various types of exploitation, as when an orchid exploits a male insect by mimicking a sexually receptive female (see pseudocopulation), but will here be restricted to forms of exploitation involving feeding. For example, indigenous Australians who dress up as and imitate kangaroos when hunting would not be considered aggressive mimics, nor would a human angler, though they are undoubtedly practising self-decoration camouflage. Treated separately is molecular mimicry, which shares some similarity; for instance a virus may mimic the molecular properties of its host, allowing it access to its cells. An alternative term, Peckhamian mimicry, has been suggested (after George and Elizabeth Peckham), but it is seldom used.

Aggressive mimicry is opposite in principle to defensive mimicry, where the mimic generally benefits from being treated as harmful. The mimic may resemble its own prey, or some other organism which is beneficial or at least not harmful to the prey. The model, i.e. the organism being 'imitated', may experience increased or reduced fitness, or may not be affected at all by the relationship. On the other hand, the signal receiver inevitably suffers from being tricked, as is the case in most mimicry complexes.

The Australian environment ranges from virtually pristine Antarctic territory and rainforests to degraded industrial areas of major cities. Forty distinct ecoregions have been identified across the Australian mainland and islands. Central Australia has a very dry climate. The interior has a number of deserts while most of the coastal areas are populated. Northern Australia experiences tropical cyclones while much of the country is prone to periodic drought. This dry and warm environment and exposure to cyclones, makes Australia particularly vulnerable to climate change -- with some areas already experiencing increases in wildfires and fragile ecosystems.

The island ecology of Australia has led to a number of unique endemic plant and animal species, notably marsupials like the kangaroo and koala. Agriculture and mining are predominant land uses which cause negative impacts on many different ecosystems. The management of the impact on the environment from the mining industry, the protection of the Great Barrier Reef, forests and native animals are recurring issues of conservation.

Kangaroo meat is produced in Australia from wild kangaroos and is exported to over 61 overseas markets.

Kangaroo meat is sourced from the four main species of kangaroos that are harvested in the wild. As of May 2024, Australia's commercial kangaroo industry is the largest commercial land-based wildlife trade on the planet. Kangaroo harvesting only occurs in approved harvest zones, with quotas set to ensure population sustainability. In Victoria, quotas were formally introduced in 2019, starting at 93,640 kangaroos and peaking at 166,750 in 2023 before decreasing to 111,575 in 2024 to balance ecological and management needs. If numbers approach minimum thresholds harvest zones are closed until populations recover. Kangaroos are harvested by licensed shooters in accordance with a strict code of practice to ensure high standards of both humaneness and food hygiene. Meat that is exported is inspected by the Department of Agriculture, Fisheries and Forestry.

A purr or whirr is a tonal fluttering sound made by some species of felids, including both larger, wild cats and the domestic cat (Felis catus), as well as two species of genets and the Caquetá titi monkey (Plecturocebus caquetensis). It varies in loudness and tone among species and in the same animal. In smaller and domestic cats it is known as a purr, while in larger felids, such as the cheetah, it is called a whirr.

Although true purring is exclusive to felids and viverrids, other animals such as raccoons produce vocalizations that sound similar to true purring. Animals that produce purr-like sounds include mongooses, kangaroos, wallabies, wallaroos, badgers, rabbits and guinea pigs.

Phalangeriformes /fəˈlændʒərɪfɔːrmiːz/ is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "(o)possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas (the term comes from Powhatan language aposoum "white animal", from Proto-Algonquian *wa·p-aʔɬemwa "white dog"). However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos.

Phalangeriformes are quadrupedal diprotodont marsupials with long tails. The smallest species, indeed the smallest diprotodont marsupial, is the Tasmanian pygmy possum, with an adult head-body length of 70 mm (2+3⁄4 in) and a weight of 10 g (3⁄8 oz). The largest are the two species of bear cuscus, which may exceed 7 kg (15 lb 7 oz). Phalangeriformes species are typically nocturnal and at least partially arboreal. They inhabit most vegetated habitats, and several species have adjusted well to urban settings. Diets range from generalist herbivores or omnivores (the common brushtail possum) to specialist browsers of eucalyptus (greater glider), insectivores (mountain pygmy possum) and nectar-feeders (honey possum).
