I so often see complaints about Aussie Post, but I have no such complaint with Australia Post. Nearly everything I have ordered has arrived, and mostly on time, or within a few days of the expected date. Since I allow for those few days I am not dissatisfied.
Of the many hundreds of orders I have only lost one significant order, a Night Vision Device. Even with tracking it disappeared, and tracing it proved fruitless. But that is okay, I got an immediate refund from the company I bought it from, with a promise that they will make up for it on my next order.
Only real issue; I bought the last NVD, and could not get another.
Australian Customs, on the other hand, have no sense of humour. They have snatched a couple of my imports lately.
