I received the offer booklet by mail in Melbourne on Tuesday 7 September, posted the cheque via Express Post on 8 September that was received in that city's GPO PO Box at just after 0400 (!) AEST on Friday 10 - lack of flights is causing Australia Post headaches, so Express Post is being sent for shorter sectors by rail or road if the AP freighter planes are full.

(Lossmaking at $5 million a day down the tube QAN is down to a typical one flight a day from Melbourne Airport to SYD, and Jetstar sometimes doesn't have any. Virgin Australia typically has one flight on this route, while REX has temporarily suspended its Boeing 737-800 major route flights).

Boardroom must have collected it on Friday as the cheque was banked that day.

All quite seamless and efficient for those who try to avoid using BPay or similar for larger amounts.
