This is provided, further to the notification of 25 September 2025, to advise of WA’s new liver fluke import conditions for horses. The import conditions are designed to reduce the risk of liver fluke entering WA and will come into effect from 1 December 2025.

Treatment requirements from 1 December 2025

Horses of WA origin, which have been absent from WA for 2 weeks or less and resided only in the liver fluke test exempt area of Australia, require no treatment (or testing).
Horses of WA origin, which have been absent from WA for 12 weeks or less and which spent any time in the liver fluke test area of Australia require a treatment (but are not required to be tested).
All other horses entering WA, regardless of the location of their property of origin or destination, must be treated for liver fluke at the Entry Inspection Point or within 48 hours before presenting to the WA border checkpoint.
Treatment of liver fluke must be with triclabendazole at a dose rate of 12mg/kg body weight (APVMA permit 13882) and be administered, or directly supervised, by a registered veterinarian or an authorised government inspector.
From 1 December 2025, horses entering WA will no longer be required to undergo post-entry liver fluke treatment.
