National Biosecurity Week, held from 25 to 31 August 2025, seeks to dispel the misconception that biosecurity is simply about border controls and hazmat suits. The campaign highlights the critical role that farmers and rural communities play in protecting Australian agriculture from pests, weeds and diseases.
Australia’s farm sector is valued at $82 billion in gross production annually, with around 70 per cent of output exported to overseas markets. The system that protects this production is under constant pressure. The Food and Agriculture Organization estimates that 40 per cent of global crop production is lost every year to pests. In Australia, 168 exotic invasive species and 42 exotic plant pests and diseases remain significant threats, while experts have warned of a 42 per cent chance of a serious exotic disease incursion within the next five years.
The consequences for producers are clear. An outbreak can bring heavy production losses, disrupt trade, impose quarantine costs and damage long-standing market relationships. Recent incursions such as varroa mite and ongoing threats from red imported fire ants show how quickly pests can spread and how difficult eradication programs can be once established.
National Biosecurity Week places emphasis on simple, practical measures that can make a major difference on farms. Farmers and workers are encouraged to:
• Clean clothing, footwear and equipment before entering or leaving properties to prevent the transfer of soil and seeds.
• Report unusual pests, diseases or weeds immediately via the Exotic Plant Pest Hotline (1800 084 881) or the Emergency Animal Disease Hotline (1800 675 888).
• Source planting material, livestock and inputs from regulated and trusted suppliers, avoiding unregulated imports and online purchases.
These everyday actions form the first line of defence in keeping harmful organisms off properties and out of the wider industry. They are supported by national initiatives such as the Biosecurity Training Hub, which provides free online resources, and the Youth Biosecurity Hub, designed to build awareness among the next generation of landholders.
National Biosecurity Week is coordinated through partnerships between governments, industry bodies and communities. Its message is clear: biosecurity is not an abstract concept managed at the border, but a responsibility shared across farms, regions and industries. By remaining alert and consistent in on-farm practices, producers can help secure the long-term productivity of Australian agriculture.
