What do Kangaroos Eat? (Facts and Favourite Food!) (2025)

Did you know that kangaroos have a diet that varies widely across species and habitats?

From the arid outback to lush coastal regions, kangaroos have adapted their eating habits to thrive in diverse environments. This article explores the dietary preferences of different kangaroo species, their nutritional needs, and how seasonal changes and human activity influence their feeding habits.

Kangaroos are predominantly herbivores, feeding mainly on native Australian plants. Their diet consists primarily of fresh grasses, but also includes flowering plants, mushrooms, ferns, and leaves. While they prefer fresh grass, they adapt their diet based on the availability of vegetation in their habitat.

What Do Kangaroos Like to Eat Most?

Researchers in New South Wales, Australia, have observed kangaroo dietary preferences, highlighting the following:

Most Preferred:

• Fresh grass
• Green perennials
• Normal grass

Less Popular:

• Salt-tolerant shrubs
• Dry grass
• Acacia (branches with leaves, buds, flowers, new shoots)
• Maireana (perennial herbaceous plants)

The study found that kangaroos significantly favor fresh green grass, resorting to dry grass only when better options are unavailable.

Dietary Preferences of Different Kangaroo Species

Kangaroo species have varied dietary preferences, particularly small kangaroos, which are especially selective. While all kangaroos primarily eat grass and share a similar digestion process with cows, they are not ruminants. Their grazing habitats are similar to those of cows and sheep.

The preferred food varies significantly among species. Very small kangaroos (under 5 kg or 11 pounds), medium-sized, and large kangaroos (over 30 kg or 66 pounds) have distinct dietary needs. Generally, larger kangaroos have less specific preferences compared to their smaller counterparts.

What Do Big Kangaroos Eat?

Larger kangaroos, such as the Red Kangaroo, primarily consume Australian grasses, rich in fiber. Unlike the smaller, more selective wallabies, these kangaroos are less picky about their food.

Dietary Habits:

• Kangaroos prefer fresh, juicy grasses for their higher nutrient content and easier digestion.
• 75% to 99% of their diet consists of grass, avoiding tall grasses but capable of surviving on dry grasses during extreme conditions.
• Shrubs are mainly eaten in winter or during droughts.

Metabolism and Nutrient Needs:

• Large kangaroos have slower metabolisms, allowing them to survive on fewer nutrients relative to their body weight.
• Males are generally less selective than females, often consuming less nutritious dry grasses.
• During extreme droughts and overgrazing, both sexes may resort to older, less nutrient-rich plants.

What Do Smaller Kangaroos Like Wallabies and Quokkas Eat?

Smaller kangaroo species like wallabies and quokkas have high metabolic rates, necessitating nutrient-rich diets. They enjoy fruits, seeds, fresh shoots, mushrooms, tubers, bulbs, roots, truffles, and flowers. Leaves, which have less fiber than grass, are a staple in their diet. Occasionally, they consume small invertebrates.

Wallabies' digestive systems and teeth are less suited for highly fibrous plants like grass, though they will eat fibrous grasses when necessary. Their diet largely depends on availability, influenced by recent weather, and they avoid toxic plants like eucalyptus leaves.

Do Kangaroos Eat Meat?

While kangaroos are primarily herbivores, there are occasional reports of them eating meat. This behavior is rare and usually opportunistic, occurring when they come across small animals or carrion. Such instances are not typical and are driven by extreme conditions or a need for additional protein. Generally, kangaroos stick to their plant-based diet, preferring grasses, leaves, and other vegetation.

What Do Baby Kangaroos Eat?

Baby kangaroos, known as joeys, have diets that differ significantly from adults.

In the first months of life, a joey feeds exclusively on its mother's milk, clinging firmly to one of the four teats inside her pouch. Interestingly, kangaroos are born outside the pouch and must climb into it to latch onto a teat for milk.

At around 8 months, joeys start peeking out of the pouch and nibbling on grass while their mother grazes. Despite this, they continue to rely mainly on milk.

Once a joey leaves the pouch, a new sibling takes its place, although the older joey may still access the milk. Only after weaning do kangaroos adopt an adult diet. Newly weaned joeys are vulnerable to drought due to their limited reserves.

Where do kangaroos find food?

Summary

Kangaroos exhibit diverse dietary habits tailored to their species and habitats, from arid outback regions to lush coastal areas. Predominantly herbivores, kangaroos primarily consume fresh grasses, along with flowering plants, mushrooms, ferns, and leaves. Their preferences adapt to the seasonal availability of vegetation, with fresh green grass being their most favored food.

Larger kangaroos like the Red Kangaroo are less selective, often consuming fibrous Australian grasses, while smaller species such as wallabies and quokkas require nutrient-rich diets including fruits, seeds, and leaves.

Though primarily plant-eaters, kangaroos occasionally consume meat in extreme conditions. Joeys rely on their mother’s milk before gradually transitioning to an adult diet.
