Sometimes we open our mailbox and there is a parcel in there. There is no way the postie could have shoved the parcel through the slot, which is about the size of the one in the photo below.

One day, Damjan asked a postman how they managed to get large items into our mailbox. He said:
‘Twenty years ago, when this area was being developed, a building manager gave Australia Post a master key to the mailboxes in his apartment building. We noticed that a lot of the new buildings had similar-looking mailboxes, so one day, a postie tried the master key in another building. And it worked.’
So it looks like Australia Post has a key to our mailbox. And our neighbour’s mailbox.
I thought about whether or not this is a privacy or security risk. Posties already have access to our mail. As long as no one loses or copies the key, which I guess is a big risk…
Oh well. It’s convenient that I don’t need to trek to the post office whenever I miss a small parcel delivery.
