History of Rabbits in Australia
Rabbits were first introduced to Australia by the First Fleet in 1788, which brought them from England. Initially, they were bred as food animals, likely in cages, to sustain the European settlement. However, despite being present in the country since the late 18th century, rabbits did not become a significant issue until the mid-19th century.
Christmas Day 1859 marked a turning point in the history of rabbits in Australia when Thomas Austin, a wealthy settler from Victoria, decided to release 13 wild rabbits on his farm at Barwon Park. Born in England, Austin was familiar with the popular sport of rabbit hunting and sought to recreate the practice by having a stable rabbit population available for hunting in the area.
The introduction of these European wild rabbits into the Australian environment allowed for their rapid and uncontrollable growth in population. With an absence of natural predators and an abundance of vegetation to feed on, the rabbit population quickly spiraled out of control. This led to significant ecological and agricultural problems, as rabbits began to compete with native species for resources and destroy crops meant for human consumption.
Over the years, several control measures have been implemented to help manage and mitigate the rabbit issue in Australia. Among these, the myxomatosis virus proved effective in reducing rabbit populations during the mid-20th century. However, despite these efforts, rabbits continue to be a persistent problem across the Australian landscape, causing damage to both the environment and agricultural industry.
In conclusion, while rabbits may have initially been brought to Australia for food and sport, their rapid population growth and impact on the Australian ecosystem have raised concerns over their presence and the need for continued control measures.
Rabbits as Invasive Species
European wild rabbits were introduced to Australia in 1859, initially with just 24 individuals. However, over time, they have become one of the most significant invasive species in the country, with their population growing to an estimated 200 million. Australia’s native flora and fauna have been heavily impacted by the rapid growth of this non-native species.
The reason behind this biological invasion is the adaptability and reproductive abilities of European rabbits. They quickly spread across the Australian continent, leading to a wide range of negative environmental effects. Some of these consequences include loss of native vegetation, soil erosion, and the decline of many native species that have to compete with rabbits for resources.
In an effort to control and manage the rabbit populations, different methods have been utilized over the years such as fences, poisons, and the release of pathogens. Some of these techniques have been more successful than others, resulting in a decrease in population numbers. Despite these efforts, the rabbit invasion continues to be a major concern for Australia’s agriculture and ecosystems.
As an invasive species, European rabbits have caused significant economic damage, with millions of dollars spent on crop losses and rabbit management. Furthermore, their presence has led to diverse ecological issues, such as disrupting delicate food chains and altering the landscape, which put Australia’s unique natural environment at risk.
Impact on Australian Ecosystem
Rabbits in Australia have a significant impact on the country’s ecosystem. As an invasive species, they pose a serious threat to native flora and fauna. Their presence causes issues such as soil erosion, degradation of native habitats, and competition for resources with native species.
One major consequence of rabbits’ presence in Australia is the widespread erosion of soil. As rabbits graze on grasses and plants, they strip the vegetation, exposing the soil to the elements. This leads to an increase in erosion, as the soil’s integrity is compromised by the removal of plant matter that would otherwise protect it. The burrowing habits of rabbits further exacerbate this issue, as their extensive burrow systems contribute to the loosening and removal of soil.
The impact of rabbits on native flora is also concerning. By feeding on various plants, rabbits pose a significant risk to the survival of native species. They have the ability to consume large amounts of vegetation, often targeting young plants and preventing them from regenerating. This selective grazing can lead to the loss of plant biodiversity, as native flora struggle to compete with the fast-reproducing rabbits.
Moreover, rabbits contribute to the degradation of grasslands and other habitats that many native fauna rely on. Through their grazing and burrowing habits, rabbits alter these habitats, making them less suitable for native species. This ecological shift can have severe consequences for many native animals, as they struggle to find adequate resources and shelter in their altered environment.
Rabbit Population Control Efforts
Australia has been facing the challenge of controlling the invasive European rabbit population for over a century. Several methods have been employed by researchers, farmers, and government agencies to mitigate the impact of rabbits on the environment and agriculture. The efforts include fencing, trapping, shooting, fumigation, and the use of poisons.
One of the most iconic measures taken was the construction of the rabbit-proof fence, spanning over 3,000 kilometers to protect Western Australia’s agriculture from rabbit invasions. However, this ambitious project had limited success due to the rabbits’ ability to breach the fence over time.
Biological controls have been a significant focus in controlling rabbit populations. The introduction of Myxomatosis, a deadly disease for rabbits, was a successful strategy in the 1950s, leading to a significant reduction in rabbit numbers. However, the rabbits began developing resistance to the disease, reducing its effectiveness over time.
A more recent biological control method is the use of Rabbit Haemorrhagic Disease Virus (RHDV). Introduced to Australia in 1995, RHDV has proven to be an effective tool in managing wild rabbit populations. However, the continuous evolution of rabbits and the virus required the introduction of a new strain of RHDV, called RHDV2, to maintain its effectiveness.
While these measures have shown varying levels of success, the rabbits’ ability to breed rapidly, adapt, and damage ecosystems persist as a challenge for Australia. Landholders are obliged to control rabbit populations on their land, with an emphasis on determining control success by the number of rabbits remaining rather than those removed. The ongoing battle against rabbit overpopulation in Australia serves as a reminder of the difficulties and complexities involved in managing invasive species.
Role of Rabbits in Australia Today
Rabbits in Australia play various roles, ranging from pets to ecological disturbances caused by feral populations. As pets, rabbits can be a popular choice among Australians, with some people even seeking out specific breeds such as the Flemish Giant Rabbit. In some areas like Queensland, owning a pet rabbit is restricted to magicians only due to the immense ecological damage caused by rabbits in the past.
Feral rabbits, on the other hand, continue to cause significant challenges to farmers, native species, and the environment in general. They compete with native species for food and habitat and destroy crops, resulting in considerable losses for farmers.
The absence of natural predators for rabbits in Australia has contributed to the uncontrolled growth of the feral rabbit population. This has led to the need for various control measures, including the construction of rabbit-proof fences and the introduction of the myxomatosis disease to reduce their numbers. Despite these efforts, rabbits continue to cause problems for farmers and the environment.
In some areas, rabbits are still hunted for their meat, which is a lean and nutritious alternative to other types of proteins. Specialty rabbit meat companies and individuals might source their rabbits from Flemish Giant Rabbit breeders or other establishments that focus on maintaining high-quality breeding standards.
In conclusion, rabbits in Australia serve different purposes, ranging from pets, a source of nutrition, to troublesome feral populations that threaten the native flora and fauna. As Australia continues dealing with the adverse effects of these animals, the balance of their role in the country’s ecosystem remains a topic of ongoing discussion.
Rabbit Diseases and Immunity
Rabbits in Australia are known to suffer from various diseases, with two notable viruses causing significant harm: the myxoma virus and the calicivirus, specifically the rabbit haemorrhagic disease virus (RHDV). These diseases have been used as biological control methods to reduce the overpopulation of rabbits in the country.
The myxoma virus is a lethal disease that was introduced in Australia in the 1950s to control rabbit populations. Initially, the virus proved highly effective, killing up to 99% of infected rabbits. However, over time, rabbits developed partial immunity, and the mortality rate from the disease gradually decreased. To maintain the effectiveness of myxomatosis as a control method, rabbit fleas (Xenopsylla cunicularis) were released as disease vectors.
On the other hand, the calicivirus, specifically the rabbit haemorrhagic disease virus (RHDV), was introduced in Australia in the 1990s. It is a highly contagious virus causing rapid death in infected rabbits. RHDV has proven to be a successful control measure for rabbit populations, particularly in dry regions of the country. In 2017, a new strain of the virus, RHDV-K5, was released to further enhance its effectiveness.
Despite the success of these diseases in reducing rabbit populations, the animals have shown remarkable adaptability. Some rabbits have developed partial immunity to both the myxoma virus and RHDV, allowing them to survive and reproduce. As a result, researchers continue to monitor rabbit populations and devise new strategies to maintain control over their numbers and reduce their impact on native ecosystems in Australia.
Current Rabbit Distribution in Australia
European rabbits (Oryctolagus cuniculus) were first introduced to Australia in the 1700s and have become one of the most widely distributed and abundant vertebrate pests in the country. They now inhabit around 70% of Australia’s landmass, which equals approximately 5.3 million square kilometers. The rabbit population is currently estimated to be around 200 million.
In New South Wales, rabbits are commonly found in various habitats, including urban areas such as Sydney and coastal regions. In Victoria, rabbits inhabit a diverse range of environments from Melbourne’s urban locales to more rural areas. Within Western Australia, they can be found throughout the region, particularly in areas with low vegetation and sandy soils.
Queensland also has a significant rabbit population, particularly in the southern parts of the state. South Australia sees rabbit populations inhabiting most areas, including near the city of Adelaide. Tasmania, being an island, has a slightly lower rabbit presence, but they are still present in various habitats across the state.
The Northern Territory, known for its unique wildlife and landscapes, is not exempt from the rabbit invasion. Rabbits can be found in various parts of the territory, posing a threat to the indigenous flora and fauna.
Rabbit populations tend to surge during certain weather conditions like La Niña events. This leads to an increase in their overall distribution and abundance across Australia.
As rabbits continue to thrive across the country, researchers and conservationists are investigating ways to control and manage the population. Some states, like California, have introduced specialized breeds of rabbits, such as the Flemish Giant, to address various rabbit-related issues.
In conclusion, rabbits are widespread and abundant in many regions across Australia, inhabiting various landscapes in most of the states and territories. This distribution poses a constant challenge for environmental management and poses a threat to Australia’s unique ecosystems.

However, they remain a significant problem in Australia due to their destructive nature and ability to breed rapidly.
What was the reason for rabbits being introduced to Australia?
Rabbits were first introduced to Australia in 1859 by Thomas Austin, who intended them to be used for recreational hunting. He did not foresee the rapid population growth and ecological damage that would result from this simple act of releasing a few rabbits into the Australian bush.
What is the ecological impact of rabbits in Australia?
Rabbits have caused extensive damage to the Australian environment by overgrazing on native plants and causing soil erosion. They compete with native species for food and shelter, leading to the decline or even extinction of some native flora and fauna. Their indiscriminate grazing can also make areas more prone to invasive species, which cause additional problems for the ecosystem.
How does Australia plan to control the rabbit population?
Various methods have been attempted throughout the 20th century to control the rabbit population in Australia. Conventional approaches include shooting rabbits and destroying their warrens, though these methods have had limited success. More recent strategies involve biological control measures, such as the release of viruses like myxomatosis and Rabbit Hemorrhagic Disease Virus (RHDV) to reduce rabbit populations. These measures have shown promising results but have not entirely eradicated the rabbit problem.
Are European rabbits still causing problems in Australia?
Yes, European rabbits continue to cause issues in Australia, despite efforts to control and reduce their population. They contribute to environmental degradation and remain a prevalent challenge for land managers, farmers, and conservationists.
Is there a distinction between rabbits and hares in Australia?
Rabbits and hares are distinct species, though they share some similarities. They both belong to the same family, Leporidae, but exist as separate genera. Hares are generally larger and faster than rabbits, and they give birth to fully furred and open-eyed young called leverets. In contrast, rabbits give birth to altricial young called kittens or kits, which are born hairless and with closed eyes. Information about the growth rate for various different breeds of rabbit can be found in a useful guide discussing the topic thoroughly.
