Thanks for your suggestion Boronia and Deeds. The vet was able to keep him up to 4 weeks and no one is allowed to drive into QLD (unless it's freight). After a few calls to interstate pet cemeteries and transport companies, no one was able to provide this service, especially for a large dog so I decided to get him cremated. Hopefully Victoria will get a pet cemetery soon, it is surely needed. Thanks again for your help.
