With the Millions of letters and parcels handled every year by Australia post I think they do a bloody good job over all.
No company is infallible, A few years ago a national freight carrier lost my 16" mirror in a box nearly one meter square for over a week.
It had been sent to Queensland then for some unknown reason returned to Sydney where it sat on a pallet in the transport companies warehouse for a week before it was eventually delivered to their sunshine coast depot for delivery to me.
So much for the said companies much vaunted tracking system.
They then refused to deliver it here to my address because they thought the road "might" flood, rather strange that as I was able to drive to their depot and pick it up myself.
Needless to say I will no longer be using said company to transport anything else in the future.
Cheers
PS I forgot to mention that the said parcel looked like it had had 15 rounds with Mohamed Ali,even though there was dozens of the obligatory "Fragile" stickers all over it.
