The Rabbit Problem
The European wild rabbit is an introduced pest throughout much of Australia, affecting natural environments, primary production, and even townships and infrastructure. They are Australia’s worst vertebrate pest, adversely affecting over 300 threatened native species, changing landscapes, and causing losses of over $200 million a year to agricultural production.
Rabbits in Australia
Rabbits were introduced to Australia in the 1800s by European settlers. Free from diseases and facing relatively few predators in a modified environment, the wild populations grew rapidly. By 1910 rabbits had spread across two thirds of Australia with devastating impact.

- Distribution & Abundance – population dynamics
Understanding the biology of rabbits helps to identify opportunities for their control. They are social, territorial animals and able to breed prolifically. A single doe can produce 50-60 offspring per year.

Rabbit Environmental Harm
European wild rabbits are a risk to 322 threatened native species in Australia – double the number at risk from cats and foxes combined. The species at risk due to rabbits include plants, mammals, birds, reptiles, invertebrates, and even fish and amphibians. A national Threat Abatement Plan has been developed for rabbits.
- Native Plants – selective feeding
- Competition – for food and burrows
- Ecological Disruption – flow-on effects
- Promoting Predators – feeding feral cats and foxes
- Soil Disturbance & Weeds – erosion, weeds and carbon sequestration
Competition for feed from rabbits reduces the productivity of grazing lands, but their consumption of green-feed and environmental impacts have implications for nearly every form of primary industry. They can also damage infrastructure and harm peri-urban properties. The ‘cost’ of rabbits includes the losses in production they cause, the repair of infrastructure, the costs of their control, and the social costs of confronting rabbits.
- Production & Profit – livestock, crops, horticulture, viticulture, forestry and revegetation
- Infrastructure & Peri-urban Costs – from roads and railways to back yard gardens
- Social Costs – affecting peri-urban and rural communities
