Quarantine Laws Western Australia

The Department of Agriculture and Food, Western Australia, through Quarantine WA, enforces quarantine laws that must be considered if you plan to move/transport freight into WA. Items may need to undergo quarantine treatments prior to entry, or will require inspection on arrival in WA.

Some items may even be prohibited entry into WA. Undeclared personal effects, containers, vehicles & machinery will usually be placed under quarantine for inspection which may result in delivery delays.

Tri State Transport is a certified Quarantine Facility for the Department of Agriculture & Foods WA & therefore can safely & securely hold freight at its depot until Quarantine clearance. For more information, please visit ​www.agric.wa.gov.au
