I'm in NSW and anything I've posted via Parcel Post gets scanned when I lodge it over the counter, scanned again when it reaches its destination PO where it says Awaiting Collection, then scanned when the recipient collects it. I've never had any scans in between, so if something does get lost, there is no way of finding where it is between here and the destination.

Even China Post has a far better tracking system! You know where it is all the time.
