Kangaroos live across nearly every ecosystem in Australia, from scorching inland deserts to cool temperate forests, tropical savannas, and even suburban neighborhoods. The four large kangaroo species each favor different habitats, and a few smaller relatives have carved out niches in places you might not expect, like tropical rainforest canopies. Where a kangaroo lives depends largely on its species, and each one has physical traits fine-tuned to its environment.
Red Kangaroos and the Arid Interior
The red kangaroo, Australia’s largest marsupial, is built for the outback. It lives throughout the semi-arid and arid regions of mainland Australia, favoring areas where annual rainfall stays below 500 millimeters. Its preferred landscapes are open plains and sparsely wooded country: grasslands, shrublands, desert flats, and open savanna woodland. These environments look sparse to the human eye, but they provide enough low scrub and grasses to sustain large populations. In New South Wales alone, the 2024 population estimate for red kangaroos across the western plains topped 5 million animals.
Surviving in these hot, dry ecosystems requires serious physiological tricks. Red kangaroos reflect about 40% of incoming solar radiation thanks to their light brown fur, compared to roughly 28% for the darker-coated grey kangaroos. That difference matters when daytime temperatures regularly exceed 45°C. Red kangaroos also use a strategy called adaptive heterothermy, allowing their body temperature to fluctuate more than most mammals would tolerate. By letting their core temperature drop lower overnight, they conserve both water and energy. When dehydrated in extreme heat, red kangaroos maintain better thermal control than their grey cousins, evaporating significantly less water while keeping a lower body temperature. These adaptations explain why red kangaroos dominate Australia’s harshest inland landscapes while grey kangaroos stick closer to the coasts and ranges.
Eastern Grey Kangaroos in Temperate Woodlands
Eastern grey kangaroos occupy the more fertile eastern third of Australia, from northern Queensland down through New South Wales, Victoria, and into Tasmania. Their core ecosystems are temperate woodlands and open forests with grassy understories. Unlike red kangaroos, eastern greys need relatively reliable rainfall and access to green grass, so they cluster in areas where forests meet grasslands.
These kangaroos live in mobs of 10 or more, moving within a home range of up to 5 kilometers. That range typically includes a mix of tree cover for shade and shelter and open grassy clearings for grazing. The mosaic of forest and grassland is key: eastern greys need both forage and cover in close proximity. This preference has made them remarkably successful in rural and even urban landscapes where humans have created exactly that kind of patchwork.
Western Grey Kangaroos in Scrub and Heathland
Western grey kangaroos range across southern Australia, from western New South Wales through South Australia and into Western Australia. They use a broader mix of habitats than their eastern relatives, turning up in woodlands, open forests, coastal heathland, scrub forests, and open grassland. Scrub forests, which develop in areas with distinct dry seasons, are a particularly common habitat.
What western greys look for is heterogeneity. They do best where several habitat types sit close together, giving them options for food and shelter within a small area. Their range overlaps with red kangaroos in the semi-arid northwest of New South Wales, but their darker coats reflect less solar radiation, making them less suited to the true desert interior. They tend to thin out as conditions get hotter and drier, sticking to areas with more reliable vegetation.
Antilopine Kangaroos in Tropical Savannas
The antilopine kangaroo (sometimes called the antilopine wallaroo) is the least familiar of the four large species, and it inhabits a completely different climate zone. Its range stretches across the tropical north of Australia, from the Kimberley region in Western Australia to the Gulf of Carpentaria in Queensland. The dominant ecosystem here is tropical savanna woodland, a landscape of scattered trees over tall grasses shaped by a pronounced wet and dry season cycle.
Antilopine kangaroos follow a daily routine dictated by this habitat. At dusk they move into open grasslands to graze, then return to wooded areas at dawn for shade and protection from predators. They also frequent valleys and low-lying floodplains along major rivers, especially spots with short green grass kept moist by seasonal flooding. This makes them dependent on the monsoon cycle in a way that no other large kangaroo species is.
Tree Kangaroos in Tropical Rainforests
Australia’s two tree kangaroo species break every assumption about kangaroo habitat. Lumholtz’s tree kangaroo and Bennett’s tree kangaroo are both restricted to the tropical rainforests of North Queensland, making them the continent’s largest arboreal leaf-eaters. They live in the canopy, gripping branches with strong forelimbs and broad hind feet adapted for climbing rather than hopping.
Lumholtz’s tree kangaroos are most commonly found in the fragmented forests of the Atherton Tablelands, where they use both remnant and secondary rainforest patches growing on rich basalt soils. Bennett’s tree kangaroos occupy a smaller range further north and are thought to have been pushed toward higher peaks by historical hunting pressure. Both species depend on dense, closed-canopy forest, a habitat that covers only a tiny fraction of Australia and is vulnerable to clearing and fragmentation.
Kangaroos in Human-Modified Landscapes
One of the most striking things about kangaroos, eastern greys in particular, is how readily they colonize landscapes shaped by people. Farmland, golf courses, sports fields, suburban parks, and even residential gardens can function as kangaroo habitat when the right ingredients are present: short grass for grazing and nearby tree cover for resting.
A detailed study in the coastal town of Anglesea, Victoria, found that a golf course formed the core of a thriving urban kangaroo population, supporting densities of 2 to 5 animals per hectare. Adult females were largely sedentary, using just part of the golf course and adjacent residential blocks year-round. Males ranged more widely during autumn and winter, moving through bush reserves, playgrounds, vacant lots, commercial properties, and backyard gardens. Kangaroos turned up across virtually every habitat type in the town.
The eastern grey kangaroo is considered the most urban-adapted of all the large macropods. At a landscape scale, its density peaks wherever forage and cover occur in a fine-grained mosaic, and many Australian towns and farming districts accidentally provide exactly that. Cleared paddocks bordered by woodland remnants, irrigated lawns next to scrubby reserves: these human-made mosaics mimic the natural woodland-grassland edges that eastern greys evolved to exploit. The result is that kangaroos are now a common part of daily life on the outskirts of Canberra, Melbourne, and dozens of regional towns, living in what researchers describe as both the “grey spaces” and “green spaces” of the urban matrix.
