I have loads of trouble with tracking and delivery times, regardless whether I lodge over the counter or post in street boxes. I always write to AP but just get the usual delivery times are estimates only. Anything I send to W.A. never shows any tracking until it's been delivered, and have been told it's because the parcels go by road I sent an Express Post parcel to W.A. last Monday and nothing is showing on tracking, it is outside the guaranteed next day delivery and will not arrive any quicker so was probably not worth sending it Express however this was at the buyers request

Tracking fails when the item is not scanned on delivery because:

* The barcode is damaged and can't be scanned properly and/or the tracking number is illegible 

* The scanner itself is malfunctioning and is unable to scan

* The scanner battery dies (either because it has not been fully charged or is not holding it's charge)

* The scanner doesn't upload to the Aussie Post system

* Human error or laziness on the delivery person's part 

When I send an item I don't give the customer a tracking number unless they request one because of the above.

The reason for this is that if a customer receives an item but the tracking number doesn't confirm this then they can lay claim to an unreceived item.
