Biosecurity

Biosecurity is fundamental for safeguarding our valuable agricultural resources against the threat and impacts of pests, weeds and diseases (pests).

Biosecurity is the management of the risk of animal and plant pests and diseases entering, emerging, establishing or spreading in Western Australia, to protect our economy, environment and the community.

To protect Western Australian agricultural industries from pests the Department of Agriculture and Food, Western Australia:

  • Works with stakeholders to identify and manage biosecurity risks.
  • Develops legislation.
  • Establishes import controls.
  • Conducts inspections.
  • Provides quarantine services as required.
