The state of WA is free of some diseases and pests that are present in other areas of Australia. To maintain this biosecurity status, livestock being imported into WA must meet import conditions and be certified as eligible for entry. These import conditions are determined by livestock species, origin of the livestock and the WA destination of the livestock. The species-specific LB1 Health Certificate provides information on the required import conditions and declares adherence to the import conditions.
Exporting producers and veterinarians are required to make declarations on the disease status of livestock being imported into WA, and the pre- and post-entry testing and treatment protocols. Declarations from importing producers are also required before importation for post-entry testing and treatment protocols.
The LB1 health certificates specific to each livestock species and commodity are used to record this information.
LB1 Health certification for movement of livestock into WA
The LB1 is species or commodity-specific and consists of 3 parts.
Records information regarding the livestock, exporting property and destination property
Requires signed declarations from:
- The exporting owner/manager for each of the import conditions as well as an overall declaration.
- A registered veterinarian or authorised government inspector for tests/treatments/inspections that they have undertaken.
- The importing owner/manager agreeing to meet all of WA’s post-entry conditions.
Provides the details on the species-specific import conditions for livestock entering WA. These import conditions may include testing, treating and inspection of the livestock pre-entry, on entry or post-entry into WA.
Amendment to APVMA Permit PER13882 – Triclabendazole use for livestock (including horses) moving into Western Australia
The Australian Pesticides and Veterinary Medicines Authority (APVMA) has issued an extension and amendment to Permit PER13882, which supports Western Australia’s (WA) liver fluke import conditions for livestock moving into WA. This permit is now in effect.
As part of the permit extension, the APVMA has included additional content regarding the use of triclabendazole, under the permit, with a precaution statement for young or pregnant livestock and restriction of use in pregnant and lactating livestock (except for cattle) where milk is for human consumption and does not have a defined withholding period. (Cattle milk withholding periods as specified in the permit continue to apply)
Use of this product in young (less than six months) or pregnant animals, at the dosage specified in the APVMA permit, must be determined by a registered veterinarian.
A registered veterinarian must be engaged to apply treatment in these cases. This aligns with the general principle that the suitability of any treatment should be considered before any veterinary medicine is applied.
Triclabendazole must not be used in lactating or pregnant livestock where milk may be used or processed for human consumption. This does not apply to cattle, where existing APVMA permit conditions continue to apply.
Where the WA published import conditions for livestock (including horses), require treatment for liver fluke with triclabendazole, the treatment must be administered in accordance with the APVMA Permit PER13882.
Refer to the APVMA permit 13882 for all usage requirements, including withholding periods and export slaughter interval. If you have questions regarding the application to specific consignments, please contact DPIRD at livestockbiosecurity@dpird.wa.gov.au.
Moving horses into Western Australia: new import conditions for liver fluke
Changes to the liver fluke import conditions for the movement of horses into WA came into effect from 1 December 2025.
These changes have been informed by a comprehensive liver fluke import risk analysis undertaken by DPIRD. This review was undertaken in consultation with representatives from the equine sector.
The resulting new requirements are based on current scientific evidence and will streamline the liver fluke import conditions for movement of horses into WA. All liver fluke requirements, as set out in Part 3 of the LB1 Health Certificate for the movement of horses into Western Australia, must be read and completed before importation into WA.
- All import conditions are being applied as pre-entry/entry requirements. There will be no post-entry liver fluke import requirements for horses that enter WA, regardless of the location of the property of origin or destination.
- New liver fluke sample collection and testing protocols detailed in Part 3 of the LB1: Health Certificate for movement of horses into Western Australia and in the factsheet: changes to liver fluke sampling and testing requirements for horse importation into Western Australia
- Treatment: All horses entering WA regardless of the location of the property of origin or destination (except horses of WA origin re-entering WA after having resided for less than 2 weeks solely in the liver fluke test exempt area), will be required to be treated for liver fluke with triclabendazole at the Entry Inspection Point or within 48 hours before presenting to the WA border checkpoint.
- Amended health certification for movement of horses into WA.
