Anybody moved from the US to Australia?

Conditions for importing dogs and cats vary depending on the country of origin. However, all animals entering Australia require an import permit, issued by AQIS. To obtain an import permit, an application to import your pet must be completed and returned to the quarantine station of your choice. Your application must include your pet's microchip number. The import permit contains Veterinary Certificate A and B which must be completed and endorsed by an official veterinarian in the country of export prior to the arrival of your pet in Australia.

The owner/importer must pay all quarantine fees associated with the import and quarantine accommodation of your dog or cat in Australia.

The Australian Quarantine and Inspection Service (AQIS) wishes to advise that
all Australian animal quarantine stations are at full capacity and all stations are fully booked for several months.

People wishing to have their pets accommodated at an Australian animal quarantine station should apply for an import permit at least 5 months in advance of anticipated departure.

An import permit does not guarantee a space at an animal quarantine station.

BOOKINGS MUST BE MADE FOR YOUR PET/S.

To book a space at an Australian animal quarantine station, a permit number is required. Once an import permit has been issued for your pet/s and you have a permit number, contact the relevant animal quarantine station to make a reservation. Please note the waiting time can be at least 5 months.

Provision of an airway bill number to the animal quarantine station will be required to confirm your pet/s reservation closer to the time of departure.

don't know, but unless your bike's got a lot of sentimental or monetary value that can't be recouped by selling it, you might be better off selling the bike in the states and buying a new one in Oz.
