Just came back from the post office with the ticket in my hand!
As it turns out the ticket has been lying there since September 5, and I just was not informed. Only after calling Australia Post this morning I found a notice in my mailbox dated September 16 (strange).
Anyway, I also called Qualiflyer this morning and they actually confirmed that the person I finalized my booking with gave me the wrong information. It IS possible to have award tickets sent to an address other than the one of the sponsor, but they need an authorization from him (which they do in any case if the ticket is for another person). Also, would I have not got my ticket today, I would have had to go to their Qualiflyer's Sydney office and pay USD100 to be issued an indemnity ticket (that's what one gets when the original ticket has been lost or stolen).
Thanks again for your comments!!
