Australia Post actually called me back! I was starting to wonder if it was going to happen; I’d even jotted down a note to call them up and find out what was happening about my call on the 23rd…. The call lasted under a minute, “We’ve spoken to the delivery contractor and been assured that future deliveries will not be left unattended, you will recieve a card and need to pick parcels up from your local post office. Thank you, goodbye.”
