We had something similar happen a couple of months ago.

We were the recipient of a 500gm express satchel coming from a seller in SA.

When it did not arrive by next afternoon I checked the tracking and it said it was delivered in Morissett near Newcastle. Long way from Caboolture, QLD.

I contacted the seller and they did not know how this had happened as they thought they sent it to the correct address.

They sent us a replacement order straight away so for us we got what we ordered but a day too late.

I never knew the outcome of the incorrectly delivered one.
