The Inland Fisheries Service does not permit the importation of any invertebrates except live blackworms (Lumbriculus variegatus). This means arthropods (like shrimp and crayfish) and molluscs (like snails and mussels) are prohibited and must not be imported. Only the live importation of aquatic organisms that are listed on the Permissible Imports List - Freshwater Aquarium Fish, are allowed in Tasmania.

Biosecurity Tasmania has jurisdiction over importation of animals into Tasmania. They issue a group permit that allows for import rules to be set by the Inland Fisheries Service.

The importation of aquarium and pond fish other than goldfish and aquarium molluscs (snail and mussels) is permitted if these conditions are met:

• The importation is by a registered fish dealer (as defined in the Inland Fisheries Act 1995)

OR holds a permit issued for import of fish under the Inland Fisheries Act 1995.

• The fish are included on the Inland Fisheries Service - Permissible Imports List – Freshwater Aquarium Fish.
• The fish are not goldfish, salmon, any Controlled Fish (as defined in the Inland Fisheries Act 1995) nor a noxious fish (as defined in the Living Marine Resources Management Act 1995)
• The import is accompanied by a form declaring the type, number and health of the fish imported.
