Yes, I know these post-types are boring and numerous, and yes, I shouldn't have used that adjective, but...
First was a letter sent to QLD, registered post for a legal matter. Took precisely 37 days to go from Canberra to Brisbane. Kudos AusPost, well done chaps and chapettes
Second was an item exported from the USA on the 15th of June (JUNE, not July). Landed in Sydney 2 days later. Aus Post tracking decided to update it today at 0618 to being in Sydney again. Maybe I'll get it the third time around the world .
More kudos.
