All imported food must comply with Australia’s biosecurity import conditions.

Check the Biosecurity Import Conditions system (BICON) to determine if the food you intend to import requires an import permit or a treatment or if it must meet any other conditions. All biosecurity requirements must be met before Imported Food Inspection Scheme requirements apply.
