National biosecurity in Australia is governed and administered by two federal government departments, the Department of Health and the Department of Agriculture, Fisheries and Forestry. The Biosecurity Act 2015 (C'wealth) and related legislation is administered by the two departments and manages biosecurity risks at the national border. The Act aims to manage biosecurity risks to human health, agriculture, native flora and fauna and the environment. It also covers Australia's international rights and obligations, and lists specific diseases which are contagious and capable of causing severe harm to human health. Each state and territory has additional legislation and protocols to cover biosecurity in their jurisdiction (post-border) including the detection of pests and diseases that have breached the national border.
The Intergovernmental Agreement on Biosecurity (IGAB) created a framework for governments to coordinate and identify priority areas of reform and action to build a stronger and more effective national biosecurity system, and established the National Biosecurity Committee (NBC) in 2012.
