Avian influenza mainly spreads between birds, but can also infect other species including humans and pigs. In birds, clinical disease is usually only seen in poultry (for example chickens and turkeys).

The Northern Australia Quarantine Strategy (NAQS) list of target pests, diseases and weeds includes, but is not limited to:
The Department of Agriculture, Fisheries and Forestry regulates the movement of goods from the Torres Strait under the Biosecurity Act 2015.
Torres Strait islands are a potential pathway for the movement of exotic pests, weeds and diseases present in countries very close to Australia—the closest Torres Strait Island of Saibai is only 3.6 km from Papua New Guinea (PNG).
Biosecurity in Torres Strait is critically important to the sustainability of the region.
The Department of Agriculture, Fisheries and Forestry regulates the movement of aircraft, goods and passengers from Torres Strait under the Biosecurity Act 2015.
This includes the monitoring of aircraft arriving on mainland Australia from designated biosecurity zones in Torres Strait, to assess any biosecurity risks posed by the aircraft or goods and passengers on board.
On 1 June 2015 the (then) Department of Agriculture and Water Resources (now the Department of Agriculture, Fisheries and Forestry) and the National Biosecurity Committee (NBC) published a discussion paper, "Modernising Australia’s approach to managing established pests and diseases of national significance".
Through the Modern Seamless Border Clearance initiative, the department has established itself as the world leader in biosecurity innovation and in streamlining border clearance.
In 2026, we continue celebrating the remarkable dogs and the dedicated people who protect Australia’s biosecurity.
