Mine were 4th at 8th. Also stuck. The issue is, even with the Japan Post order being the 10th, most (all?) flights from Japan stopped coming to Australia long before that. From what I can gather, EMS usually hitches a ride on normal passenger flights. No passenger flights, no EMS mail. Even if there WERE flights from Japan to Australia still, thy'd be extremely limited and probably prioritised.
Amiami is supposedly resending items via DHL at their own cost. But that is still reliant on the package being returned to point of origin.
Basically... I doubt we are getting our items. And probably a wait on getting money back.
