Where do I start? It's usually the Couriers that get it wrong. Australia Post is much better for us, but a lot of companies insist on using couriers for online purchases. This also means that we can't use our Post Office box for deliveries as some couriers have to be door to door. I'd much rather the package was left with Australia Post with a card in my PO Box because it's more secure than having a package left unattended and in full view of the public at my front door.
So here are some of the issues we've had in the past couple of years.
TOLL Courier Delivery once gave us a card in the letter box to say that we weren't home for a scheduled delivery even though we went out of our way to stay home so someone could sign for it when it arrived. The driver just couldn't be bothered walking up to the door with our package and ringing the bell or knocking on the door.
Another time, a Star Track Express delivery driver had a parcel for some other address that didn't even resemble ours, but decided to place a card on our front door to say that we weren't home (which we weren't this time, because we weren't expecting any parcels, especially parcels addressed to some other house in some other street). The package was left for collection at the local Post Office so we had no idea it was for the wrong address until we went to pick it up. It was then our responsibility to contact Star Track to get them to pick it up so they could take it to the correct address.
TNT is also guilty of leaving a note to say no one was home without even attempting to knock on the door to see if anyone was actually home or not.
Star Track Couriers had a simple task of delivering a package from Northern Tassie to Southern Tassie for us one time, which should have been an overnight delivery, so they sent it via Melbourne where it had a week's holiday before eventually being sent back to Tassie.
TNT managed to destroy every single blu-ray cover in a boxed set of 9 season's worth of The Big Bang Theory recently. JB HiFi happily replaced the set for us.
I don't remember which courier service it was, but one recently left a parcel at our laundry door instead of our front door, even though we were home to collect it, and the parcel was clearly marked, by the courier company itself, with the words 'Do not leave unattended'
Most of these problems occurred when we lived at our previous address, and we've had far less problems with deliveries since we moved. So I'm guessing it depends on which area you live in and the attitude of the driver for your particular area.
The only issue I have with Australia Post is their new system of having faster deliveries if you pay extra. Packages that used to come from the mainland to Tassie, would go to Victoria, then get shipped straight to Tassie. Now they keep the packages in Victoria for up to a week before they cross the Bass Strait, so it's not really a case of pay more and get your parcel quicker than it used to be. It's more a case of don't pay more and they'll hold onto your mail for a week before they do anything with it. You need to pay the extra so they don't hold your packages to ransom, which is never given as an option by most online stores that use Australia Post, so we're stuck with the new slower service whether we like it or not.
One last point, Star Track is actually owned and operated by Australia Post, yet the service is less reliable than their cheaper to use Australia Post Parcel Post service. Why any company would choose Australia Post's Star Track over Australia Post's Parcel Post service is a bit of a mystery for me, but we're stuck with whatever courier each online store chooses to use. Parcel Post might be slower, but at least we have a better chance of getting our packages with them, AND they deliver to Post Office boxes.
