Pet Transport from Australia to USA: CDC Rules and the Documentation Process

Australia to USA is a long-haul route (14-24 hours depending on the connection), and the documentation requirements have become more complex following the CDC’s 2024 dog import rule changes. Cats have a simpler process.

CDC’s 2024 dog import rules

The key change for dogs is the microchip-vaccination timing rule: the microchip must have been implanted on or before the date of the first rabies vaccination. If your dog was vaccinated before being microchipped, or if you’re not sure about the order, the rabies vaccination course may need to be repeated (boosted) after microchipping for the vaccination to be considered valid under CDC rules.

Australia is classed as a low-risk country for dog screwworm, which means the separate screwworm treatment that some other origin countries require does not apply.

Health certificate

Dogs need a health certificate completed by a vet in Australia and endorsed by USDA APHIS (or the equivalent Australian government authority in USDA-accepted format). The Australian Veterinary Association and the Australian Department of Agriculture, Fisheries and Forestry can advise on the correct format.

Cats

Cats do not require CDC permits or specific federal health certificates for USA entry. A vet health certificate is recommended and individual states may have their own requirements.

The flight itself

Australia-USA is among the longest pet transport routes in the world. The journey typically routes through Los Angeles (LAX) or other West Coast hubs. Pets travel as cargo. The long flight time plus temperature requirements at both ends make airline selection and transit timing important. Most direct routes (Qantas Sydney-Los Angeles, for example) are around 14-15 hours. Connecting via Asia adds significant time.

On arrival in the USA

USDA APHIS or CBP (Customs and Border Protection) inspectors at the port of entry check documentation and may inspect the animal. Declare your pet on the customs form.
