China (not including Hong Kong and Macau) is not an AQIS approved country. This means you can not import a cat or dog to Australia directly from China (not including Hong Kong and Macau).
The importation of cats and dogs from a DAFF non approved country can only occur indirectly via DAFF approved country.
If you intend to import cats and dogs indirectly via DAFF approved country, you must first contact the quarantine service in the DAFF approved country to ensure that cats and dogs are eligible for entry. Cats and dogs must meet all of the pre and post-entry quarantine requirements of the DAFF approved country.
Cats and dogs must be continuously resident in DAFF approved country for a minimum of six months prior to export. There are no exceptions to this requirement. Cats and dogs must meet all of the DAFF import conditions that apply to the DAFF approved country before being eligible for import into Australia.
