It's up to you. Since its the main postal service of Aus I doubt they'd impose any fines on him.

Remember, "YOU" didn't receive the parcel nor sign for it. I honestly think you should stick with the plan. You didn't receive the parcel. If your postie brings up your friend, your friend can say the parcel he signed was for something completely different.

I mean he obviously remembers both packages being delivered. And my friend signing both packages.
So I'm really not sure how to play this out
