To start with, I sent an airmail with a notartised declaration to China. Two months later, we decided it is, for sure, lost! We sent an international express envelop for just under $15 and it arrived in Beijing (yes, the capital city with multiple international flights departing Melbourne daily) 3 weeks later. I do not dispute the Austpost counterpart in China may have also contributed to this delay but I strongly believe it is up to Austpost to liaise with its counterparts around the world. How could DHL, TNT and others survive and compete? I gave up on Austpost and thanks for being so useless!
