Hybrids: Any domestic/non-domestic animal hybrids (e.g. Savannah cats or wolf-dog crosses) are not eligible for import. The only exception to this is the Bengal cat (Felis catus x Prionailurus bengalensis) which may continue to be imported provided it is five generations removed from the Asian Leopard Cat (Prionailurus bengalensis).

Some hybrid animals have been imported into Australia for a significant period of time, including the Bengal cat. This hybrid has been imported into Australia since 1996. The Department accepts this to be a legacy issue and its approach is to recognise the Bengal cat as an exception to the general policy.
