Kangaroos are a protected native species of Australia, and they form an integral part of the country's natural ecosystems. There are four main species of kangaroos: the red kangaroo, the eastern grey kangaroo, the western grey kangaroo, and the antilopine kangaroo. These species are spread across Australia, and while they may coexist in captivity, they rarely mix in the wild. In addition to these four, there are two species of wallaroo, which are closely related to the red kangaroo.

Red kangaroos are the largest species and are found in arid areas of Australia
There are four species of kangaroos: the red kangaroo, eastern grey kangaroo, western grey kangaroo, and the antilopine kangaroo. Of these, the red kangaroo is the largest species, with males weighing up to 90 kg and reaching heights of 2 metres. They are found across mainland Australia, particularly in arid and semi-arid regions, such as the outback of the Northern Territory. Red kangaroos prefer flat, open plains with sparse vegetation, including grassland, shrubland, desert, and open forest. They are well-adapted to the arid environment, with the ability to conserve water and select fresh vegetation.
Red kangaroos are crepuscular and nocturnal, resting in the shade during the day and becoming more active at night. They rely on small saltbushes or mulga bushes for shelter in extreme heat. Their diet primarily consists of green vegetation, especially fresh grasses, and they are capable of finding enough food even in dry conditions. Red kangaroos live in small groups of 2-4 members, typically consisting of females and their young, with males joining in densely populated areas.
Red kangaroos are an abundant species, having benefited from the spread of agriculture and the creation of man-made water sources. However, they also face challenges, such as competition with livestock and rabbits, and are sometimes considered pests by farmers. Despite this, they are protected by legislation, and their meat and hide are regulated for harvest.
Red kangaroos are an iconic symbol of Australia, known for their large size, powerful hind legs, and distinctive red colouring in males. They are featured on the Australian coat of arms as a symbol of national progress, representing an animal that can only move forward.

Eastern grey kangaroos are the most populous species and are found in the east and southeast
There are four species of kangaroos in Australia: the red kangaroo, the eastern grey kangaroo, the western grey kangaroo, and the antilopine kangaroo. The eastern grey kangaroo is the most populous species, with millions of individuals in mainland Australia. They are found in the east and southeast of the country, predominantly along the east coast, and their range extends from Cape York in northern Queensland down to Victoria, as well as southeastern Australia and Tasmania. They are also found in all altitudes of woodlands up to subalpine areas.
Eastern grey kangaroos are easily recognised by their distinctive soft grey coats, with a darker face and a dark-tipped tail. They are the second-largest and heaviest living marsupial and native land mammal in Australia, with adult males commonly weighing around 50 to 66 kg and females around 17 to 40 kg. The largest known specimen weighed 91 kg and measured 2.92 m along its curves. Eastern greys are found in a variety of habitats, from semi-arid mallee scrub to woodlands and forested areas, and they prefer the wetter, more fertile parts of Australia. They are mainly nocturnal and crepuscular, and they communicate through a series of clucking sounds.
Eastern grey kangaroos are a mob species, generally congregating in groups of about ten, though these groups can be much larger. They are herbivores, grazing on a wide variety of grasses and other plants, including fungi. They prefer young, green shoots that are high in protein, as dry grass is difficult for them to digest. They are most active in the early morning or late afternoon, avoiding the hottest part of the day, and they rest in the shade or shelter of trees or scrub during the middle of the day.
Eastern grey kangaroos are protected by law in Australia, and they are one of four abundant species that can be commercially harvested for export by licensed hunters. They are not considered threatened or endangered, and their status is secure.

Western grey kangaroos are found in the southern and western areas of the country
There are four species of kangaroos in Australia: red kangaroos, eastern grey kangaroos, western grey kangaroos, and antilopine kangaroos. Western grey kangaroos (Macropus fuliginosus) are found in the southern and western areas of the country, including Western Australia, South Australia near the coast, and the Murray-Darling basin. They are not found in the far north or southeast of Australia.
Western grey kangaroos are slightly smaller than red kangaroos, with large males weighing around 54 kg (119 lb). They have darker grey-brown fur and darker colouration around the head, sometimes with a blackish patch around the elbow. They are most active from late afternoon to early morning and typically rest under trees and shrubs during the day. They usually live in groups or "mobs" of 40 to 50 individuals, while older males may be solitary.
Western grey kangaroos are distinguished by two subspecies: one from Kangaroo Island, with dark brown to black fur and shorter limbs, ears, and tails; and the other from the mainland, with darker brown heads and backs, and bluish-grey fur underneath. The Kangaroo Island western grey kangaroo (Macropus fuliginosus fuliginosus) is endemic to Kangaroo Island, South Australia, while the mainland subspecies (Macropus fuliginosus melanops) has a range of forms that intergrade clinally from west to east.
Commercial hunting of western grey kangaroos is permitted in New South Wales, mainland South Australia, and Western Australia but prohibited in Tasmania, Northern Territory, and Kangaroo Island. Populations may have declined, particularly in agricultural areas, but western grey kangaroos are relatively plentiful.

Antilopine kangaroos are found in northern Australia and have longer limbs
Australia is home to several species of kangaroos, including the red kangaroo, eastern grey kangaroo, western grey kangaroo, and the antilopine kangaroo. Antilopine kangaroos, also known as antilopine wallaroos or wallabies, are found in northern Australia, particularly in tropical regions. They inhabit areas such as Cape York Peninsula in Queensland, the Top End of the Northern Territory, and the Kimberley region of Western Australia.
Antilopine kangaroos have evolved to thrive in the challenging tropical climate of northern Australia. They have developed sophisticated behavioural patterns and reproductive strategies that enable them to adapt to their environment. For example, they can breed throughout the year, but they prefer to time their births to coincide with the onset of the wet season when food resources are more abundant, maximizing their offspring's chances of survival.
The antilopine kangaroo is one of the largest macropods, second only in size to the red kangaroo and eastern grey kangaroo. They are known for their long and slender limbs, with darker paws on their front and hind legs that contrast with their lighter fur. Antilopine kangaroos are gregarious and form social groupings, with males establishing hierarchical dominance within the groups. During the wet season, they are most active and form larger social groups of up to 30 individuals, taking advantage of the abundant food resources.
The species is locally common in parts of its range, but its distribution is patchy. They prefer tropical habitats with perennial grasses at elevations below 500 meters, often found in association with monsoonal eucalypt woodlands and open plains. Their ability to adapt their behaviour and reproductive timing to environmental conditions has allowed them to thrive in northern Australia's demanding climate. However, despite their adaptability, the antilopine kangaroo faces challenges, including population decline in some traditional strongholds. Ongoing monitoring is required to ensure their long-term survival as a unique species in Australia's ecology.

Common wallaroos are found across Australia, especially near rocky outcrops
There are four species of kangaroos: the red kangaroo, eastern grey kangaroo, western grey kangaroo, and the antilopine kangaroo. These species are spread across Australia, though they rarely mix in the wild.
One particular species, the common wallaroo, is found across most of Australia, especially near rocky outcrops. They are native to the country and are also known as 'hill kangaroos'. They inhabit a wide variety of habitats, including forests, savannas, shrublands, and grasslands. They are commonly found in steep escarpments, rocky hills, and caves, which they use to seek shelter from extreme heat.
Common wallaroos are widely distributed throughout the Australian mainland, though they are absent from southern regions and Tasmania. They are polygynous, meaning male wallaroos have more than one female partner. They are also opportunistic breeders, able to breed throughout the year when conditions are favorable.
The common wallaroo has short, reddish-brown to dark blue-grey fur. They have shorter, wider torsos and shorter limbs than other kangaroos and wallaroos. Their shorter and broader hind feet have roughened soles, providing extra grip for their rocky terrain. They are herbivores and feed on soft-textured grasses, shrub foliage, and coarse tussock grasses. They can survive two to three months without drinking, obtaining water from their food.
The common wallaroo is not considered under threat. In fact, they are subject to control measures to supply the food and skin industry. They are also removed from cropping lands, where they are seen as a threat.
