I have 3 parcels from New Zealand NZPOST.co.nz show they all arrived 19.2.24. Australia Post said they had 2 packages in Adelaide on 19th now are in transit from NZ to Adelaide.
Courier companies have no problems. I can get a UPS parcel from USA economy post in 1 week with recent HDD purchases a couple of weeks ago. Amazon can deliver from USA/AU in less than a week and it takes Australia Post 7 days or more domestic Adelaide, or 2 weeks from interstate?
What level of service are the sending parties paying for?
I prefer shopping at Amazon to fund Jeff's space/high-atmosphere jaunts.
