I'm with you, Leon.
I insist on Aus Post, as I get deliveries here 5 days per week. Syd 2-3 days, Melb 3-4 days, Bris a week.
Considering I'm about 53kms from town, that's exceptional.
(Courier companies insist I collect from depots 53 kms away, even though they have accepted the consignment, in full knowledge they will not complete the delivery!

)
Auspost is having a period of catchup/nopickups this week due to backlogs, and that's acceptable to me considering their staffing issues re the pandemic.
