I am tracking a parcel fro the UK to Australia by the Global Shipping Program. The tracking number displayed on the EBay site is fine until the parcel arrived in Brisbane customs. At this point the parcel is handed over to Australia Post but they tell me the tracking number I have been using is not valid even though wndirect.com.au transfers me into Australia Post.
Why is this tracking number suddenly now not valid?
Can some please advise?
