Feral deer are an increasing and significant invasive species across New South Wales, causing substantial damage to agricultural land, native ecosystems and rural infrastructure. Species such as fallow, red, rusa and sambar deer can heavily impact pastures, crops and fencing, while browsing and trampling native vegetation, waterways and sensitive habitats. Their expanding populations and wide roaming behaviour make feral deer a growing biosecurity and environmental management challenge for landholders.

Under the NSW Biosecurity Act, landholders have a general biosecurity duty to prevent, eliminate or minimise the risks posed by pest animals on their property. Where deer are declared pest animals in certain land tenures or regions, proactive management is essential to limit impacts on neighbouring land, livestock production and biodiversity.

Effective feral deer control requires planned, lawful and targeted strategies. Deer are highly mobile, intelligent animals with strong flight responses, meaning poorly planned or ad‑hoc control efforts can increase dispersal and long‑term management challenges. Professional control programs use species‑specific knowledge and coordinated methods to achieve meaningful population reduction.

Licensed feral pest control operators in NSW may employ a combination of approved control methods, including:

• Thermal‑assisted and night operations to identify deer movement patterns and target animals during high‑activity periods
• GPS mapping and property surveillance to track activity corridors, feeding areas and pressure points
• Targeted shooting operations, undertaken lawfully and humanely by licensed operators
• Planned access and safety management, ensuring operations meet legislative and animal welfare requirements
• Coordinated landholder and boundary engagement to improve outcomes across larger areas

All control activities are conducted with a strong focus on compliance, safety, and animal welfare, and in accordance with NSW regulations and landholder permissions

Professional feral deer management can assist landholders to:

• Protect pastures, crops and grazing systems
• Reduce damage to fencing, water infrastructure and access tracks
• Minimize environmental degradation and soil erosion
• Safeguard native vegetation, waterways and biodiversity
• Reduce vehicle collision risks on rural properties
• Strengthen long‑term property biosecurity and land condition

Across New South Wales, successful feral deer control is best achieved through tailored, property‑specific management programs. Each property presents unique challenges depending on terrain, deer density, seasonal movement and surrounding land use.

By selecting the right combination of control techniques and coordinating efforts where possible, landholders can achieve more sustainable, long‑term reductions in feral deer pressure while meeting their biosecurity responsibilities
