In 1859, Australia faced the beginning of a disaster that would drastically affect its ecosystems for centuries. It all started with the release of just 24 rabbits, introduced by a landowner who thought they would be a great hunting resource.
Little did he know that this single act would trigger Australia’s Rabbit Plague, one of the worst ecological disasters the continent has ever witnessed. Within decades, the rabbits’ population exploded, and the impact on Australia’s environment was irreversible.

The Start of Australia’s Rabbit Plague
Australia’s Rabbit Plague began with a simple act in 1859. Thomas Austin, a settler from England, introduced 24 rabbits to his land in Victoria. He thought they would provide hunting opportunities. Little did he know, this act would trigger one of the worst ecological disasters in Australian history.
Australia’s climate and absence of natural predators allowed rabbits to thrive unchecked. They bred rapidly, multiplying at an astonishing rate. By the early 1900s, rabbits had spread across the country, their numbers growing uncontrollably.
The Ecological Fallout of Australia’s Rabbit Plague
By the time Australia’s Rabbit Plague reached its peak, the rabbits’ population soared into the hundreds of millions. This rapid growth was catastrophic. The land and its vegetation couldn’t withstand the strain. Rabbits, being herbivores, devoured grass, shrubs, and trees, causing severe damage to the environment.
As rabbits consumed vast amounts of plant life, the land began to degrade. Vegetation was stripped away, leaving large areas barren. This destruction led to soil erosion, further harming the land and threatening native species.
The Impact on Native Species
The effects of Australia’s Rabbit Plague were devastating for native species. Many animals, such as the bilby and the western ground parrot, struggled to find food as rabbits dominated the landscape. These native herbivores were pushed out by the invasive rabbits. The result was a drastic decline in populations of native species.
The loss of vegetation also meant that the soil eroded, creating a chain reaction. Native plants lost their habitat, and many native animals could no longer survive. This disruption to the food chain had long-lasting effects on Australia’s biodiversity.
Efforts to Control Australia’s Rabbit Plague
In response to Australia’s Rabbit Plague, the government took action. The first major effort came in 1950 with the introduction of the myxoma virus, a disease that affects rabbits. At first, the virus was successful, reducing rabbit numbers. However, rabbits soon developed resistance to the virus, and their population rebounded.
In 1995, another virus, the rabbit calicivirus, was introduced. This method worked better, but like the myxoma virus, its effectiveness faded over time. Today, scientists continue to explore new methods to control the rabbit population and prevent further damage to Australia’s ecosystems.
What We Can Learn from Australia’s Rabbit Plague
Australia’s Rabbit Plague is a powerful reminder of the dangers of introducing non-native species into delicate ecosystems. What started as a harmless experiment quickly escalated into an ongoing environmental crisis. The legacy of the rabbit plague is still felt today, with efforts to control the population continuing.
The introduction of rabbits has scarred Australia’s landscapes, and the recovery of native species will take time. The long-term effects of the plague, including soil erosion and loss of vegetation, have left lasting marks on the environment.
Conclusion: A Cautionary Tale
The story of Australia’s Rabbit Plague serves as a warning about the unintended consequences of introducing non-native species. What began as a simple idea in 1859 became one of the most damaging ecological events in Australia’s history. It disrupted ecosystems, drove species to the brink of extinction, and caused widespread environmental damage.
Today, Australia continues to fight the rabbit invasion. The rabbit plague has left an indelible mark, but it also serves as a cautionary tale. We must think carefully about the effects of introducing non-native species into new environments, as the consequences can be far-reaching and irreversible.
