Yes, that package had gone through Germany.
The green label from German Customs service leads me to suspect that the package made its journey from Australia, at least partly, via surface/seamail. That would explain the time it took.
All regular airmail from and to Germany goes through customs at Frankfurt International Airport (excluding UPS, FedEx, DHL, ectr. They have special handling places). This package, however, went through Hamburg, Germany's largest seaport.
