A further weird thing i have noticed now.
I logged into my account... the flight has not posted ok.... but I clicked on my bookings just for a lark, and the booking is still sitting there for 30 Oct... when I select it to view it has the flight I was changed to (I was on QF419 but I was moved to 415 as I got to domestic transfer around 0715 very quickly through customs) but the flight details are greyed out (because the date has passed I guess)...
very weird. I guess because the QF staffers just ripped the BP and didn't process them the system doesn't have proof I flew on the flight.
annoying...
