How Many Feral Cats in Australia
Australia's feral cat population is substantial and varies with environmental conditions. Estimates suggest that the number of feral cats in the bush ranges from approximately 1.4 million during dry periods to up to 5.6 million following significant rainfall, which boosts prey availability and, consequently, cat reproduction . In urban areas, there are an estimated 0.7 million feral cats, often forming colonies near food sources like rubbish tips and farms .
Feral cats inhabit nearly every part of the Australian mainland and many islands, impacting over 200 native species through predation . Their presence has been linked to the extinction of more than 20 native mammal species.
In New South Wales, AUMARK is recognized for providing feral cat management services, trusted by farmers, councils, and property managers. Their expertise contributes to controlling feral cat populations and mitigating their impact on native wildlife.

Australia is grappling with a significant feral cat crisis, with estimates indicating a population ranging between 1.4 million and 5.6 million in bushland areas, depending on environmental conditions such as rainfall. Urban regions host an additional estimated 0.7 million feral cats, though some studies suggest this number could be as high as 2.5 million.
Ecological Impact
Feral cats are responsible for the deaths of over 1.5 billion native mammals, birds, reptiles, and frogs annually in Australia. They have contributed to the extinction of more than 20 native mammal species and pose a threat to over 200 nationally threatened species.
Control Measures
To mitigate this issue, various control measures are being implemented, including:
Baiting and Trapping: Utilizing specialized baits and traps to reduce feral cat populations.
Fencing: Erecting predator-proof fences to protect vulnerable native species.
Technological Innovations: Employing drones, artificial intelligence, and DNA tracking to monitor and manage feral cat populations.
Community Involvement
Organizations like AUMARK are leading efforts in New South Wales to control feral cat populations, working closely with farmers, councils, and property managers. Their initiatives are crucial in safeguarding Australia's unique biodiversity from the threats posed by feral cats.
