If you keep livestock on your block or in your backyard, you need to register for a Property Identification Code (PIC).
In the Northern Territory a PIC is a free registration code that identifies the property where your livestock are kept.
Livestock includes alpacas, buffalo, camels, cattle, deer, goats, horses, llamas, pigs, sheep, beehives, pigeons, poultry (inc. chickens, turkeys, ducks, geese, and guinea fowl, etc), under the Livestock Act and Regulations.
Help keep your livestock safe in the event of a disease outbreak, bushfire or animal emergency, and register. Registering for a PIC is easy and free, register online.
