Good on you for being honest punter . That should bring you some good pinball karma for sure
If they get back to you and tell you to forward it to the correct recipient in Hungary I'd be very wary of doing so . If the package some how gets lost between Australia and Hungary then the onus for the package could/will be on your head . I'd specify to Marco that you will strictly only post it back to them and it's up to them to forward it to Hungary .
P.S - So what was in the package anyway ....
