Waren, the figures don't surprise me at all. The amount of middle managers in Qantas needs to be seen to be believed.
Also many QF mainline staff, paid by mainline are supporting Jetstar, Qlink, EFA, Network Businesses etc, such as treasury, legal, government, media and corporate relations, advertising etc.
Funnily the media never seem to question the amount of staff in Qantas HQ when they talk about cost cutting measures. It's always those overpaid pilots or engineers.
