Australia is home to a variety of buffalo species, including the water buffalo, which was introduced to the continent in the 19th century. Native to the Indian subcontinent and Southeast Asia, water buffalo were brought to Australia as working animals and for meat. Over time, some of these buffalo escaped and became feral, establishing wild populations in the country's northern regions. While the dietary habits of feral water buffalo in Australia are not extensively detailed, their counterparts in other regions primarily feed on grass, shrubs, and other vegetation. In addition, Australia's savanna ecosystems are home to a diverse range of creatures, from the antilopine wallaroo and frill-necked lizard to the emu, each with their own unique dietary preferences.

What You'll Learn
Water buffalo were imported to Australia in the 19th century
Water buffalo, or Bubalus bubalis, were imported to Australia in the 19th century, specifically to the Northern Territory between 1826 and 1866. They were introduced as working animals and a source of meat for the remote northern settlements. When these early settlements were abandoned, the buffalo were released and became feral.
The water buffalo is a large bovid that originated in the Indian subcontinent and Southeast Asia. They can also be found in the Balkans, Egypt, Italy, and some African countries. There are two main types of water buffalo: the river buffalo, which is native to the Indian subcontinent and can be found further west in the Balkans, Egypt, and Italy; and the swamp buffalo, which is native to Mainland Southeast Asia and can be found as far east as the Yangtze Valley in China.
Water buffalo are known to be successful grazers, and they inhabit a wide range of habitats, including savannas, swamps, floodplains, grasslands, and forests, as long as they are close to a water source. They devote a large portion of their time to grazing and feeding on grass, just like cows, and they also chew their cud to extract more nutrients from their food.
In Australia, feral buffalo populations have grown and are considered pests, particularly in the northern floodplains. They can cause significant environmental damage through their movement and feeding habits. For example, their swim channels in floodplains can destroy vegetation and erode soil, leading to saltwater intrusion into freshwater plains and the loss of forests. They have also helped spread invasive weeds and reduced the nesting activity of magpie geese and crocodiles, impacting the natural ecosystem.

They are large herbivores weighing between 450-1200kg
Water buffaloes (Bubalus bubalis) are large herbivores that weigh between 450 and 1200 kg. They are native to the Indian subcontinent and Southeast Asia, but a large feral population was established in northern Australia in the 19th century. They were originally imported as working animals and for meat, but when the settlements were abandoned, they were released and became feral.
Water buffaloes are well-adapted to their environment and thrive on a variety of aquatic plants. During floods, they can graze while submerged, raising their heads above the water to breathe. They eat a variety of plants, including reeds, Arundo donax, Cyperaceae, Eichhornia crassipes, and Juncaceae. They also consume green fodders such as alfalfa, banana leaves, cassava, Mangelwurzel, maize, oats, peanut, sorghum, soybean, sugarcane, and turnips.
Water buffaloes are important for local people, as they can help control invasive plant species such as E. crassipes and A. donax. They are also valuable for milk production, as their milk is richer in fat and protein than that of dairy cattle.
In Australia, water buffaloes are considered pests due to their environmental impact. They can cause damage through their movement and feeding habits, particularly in floodplain areas. They create swim channels that erode soil and allow saltwater to intrude into freshwater plains. They also help spread weeds, such as Mimosa pigra, which can negatively affect the natural ecosystem and recreational activities like hunting.

Buffaloes eat shrubs and vegetation during the dry season
Water buffaloes, also called domestic water buffalo, Asian water buffalo, or Asiatic water buffalo, were imported into the Northern Territory of Australia in the 19th century as working animals and meat for the remote northern settlements. When the early settlements were abandoned, the buffaloes were released, becoming feral.
Feral buffaloes are large herbivores, weighing between 450kg and 1200kg. They are generally found only in areas that receive greater than 1000mm of rainfall each year. They devote a large portion of their time to grazing and feeding. During the dry season, when grass is scarce, they eat shrubs and other vegetation, although they prefer the open grasslands where they can graze freely. Their grazing habits help maintain the savanna ecosystem by preventing grasses from becoming overgrown.
Like the plains zebra, the buffalo can live on tall, coarse grasses. They mow down grasses with their tongue and wide incisor row, making way for more selective grazers. They inhabit a wide range of habitats, including semi-arid bushland and montane grasslands to coastal savannas and lowland rainforests, as long as they are close to a water source.
Cape buffaloes, a subspecies of African buffalo, are primarily found in the savannas and grasslands of southern and eastern Africa, as well as parts of central Africa. They thrive in areas with plenty of water, as they need to drink large amounts daily to survive. This is why herds are often seen near rivers, lakes, or swamps, especially during the dry season.

They are found in areas with over 1000mm of rainfall per year
Water buffaloes, also known as domestic water buffalo, Asian water buffalo, or Asiatic water buffalo, are large bovids that originated in the Indian subcontinent and Southeast Asia. They are now found in many parts of the world, including Australia, where a large feral population was established in the northern regions of the country in the 19th century.
Water buffaloes were imported to Australia as working animals and a source of meat for remote northern settlements. When these early settlements were abandoned, the buffaloes were released and became feral. Today, they are considered a pest in certain areas, such as the Top End, particularly in the northern floodplains.
These buffaloes are typically found in areas with over 1000 mm of rainfall per year, such as floodplains, woodland, and sandstone escarpment regions where surface water is present. They are well-adapted to their environment and can even graze submerged during floods, raising their heads above the water while feeding on aquatic plants.
In Australia, water buffaloes primarily inhabit floodplain areas, where they create pathways known as swim channels. While these channels aid in the buffaloes' movement, they also lead to environmental damage, including vegetation destruction and soil erosion. Additionally, these channels can cause saltwater intrusion into freshwater plains, as observed in the Mary River area.
The presence of water buffaloes in Australia has significant ecological implications. They feed on a variety of plants, including reeds, Arundo donax, Cyperaceae, Eichhornia crassipes, and Juncaceae. Notably, by consuming invasive plants like E. crassipes and A. donax, water buffaloes may play a role in controlling these species in certain tropical valleys.

River and swamp buffalo are the two types of water buffalo
The water buffalo, also known as the domestic water buffalo, Asian water buffalo, or Asiatic water buffalo, is a large bovid that originated in the Indian subcontinent and Southeast Asia. Today, they can also be found in Australia, North America, South America, and some African countries. There are two types of water buffalo: the river buffalo and the swamp buffalo.
The river buffalo is native to the Indian subcontinent and can also be found in the Balkans, Egypt, and Italy. It has a long face, smaller girth, and bigger limbs compared to the swamp buffalo. Its dorsal ridge extends further back and tapers off gradually. Its horns grow downward and backward before curving upward in a spiral. The skin of the river buffalo is typically black, but some may have dark, slate-coloured skin. It prefers deep water and is well-adapted to hot and humid climates.
The swamp buffalo, on the other hand, is native to Assam in western India and can be found throughout Southeast Asia up to the Yangtze Valley in China. It has a heavy and stocky build, with a short body and large belly. Its forehead is flat, and its face is short with a wide muzzle. The swamp buffalo's horns grow outward and curve in a semicircle. At birth, its skin is grey, but it turns slate blue as it matures. Swamp buffaloes prefer to wallow in mudholes, which they create with their horns.
Both types of water buffalo have different chromosome numbers, with the swamp buffalo having 48 and the river buffalo having 50. While they do not readily interbreed, fertile offspring can occur. Water buffalo are known to consume various plants, including invasive species such as E. crassipes and A. donax, and they are particularly useful for tilling rice fields.
In Australia, water buffaloes were introduced in the late 19th century, and they have since established a large feral population in the country's north. While this answer focuses on the two types of water buffalo, it is worth noting that in Africa, there are four recognised subspecies of buffalo: the forest buffalo, West African savanna buffalo, Central African buffalo, and southern savanna buffalo (also known as the Cape buffalo). These African buffaloes are excellent grazers and inhabit a range of habitats, including savannas, swamps, and grasslands, as long as they are close to a water source.
