Would departing on QF10 from London to Melbourne on 31 August count towards this offer, given that the flight doesn't land in Melbourne until 1 September?

I couldn't agree more! I've had eight 2-3 hour stops in Dubai over the last couple of years and I've never been able to get a shower in the business lounge. No such problem in Singapore, Hong Kong etc. And the queuing system is rather chaotic. Your name gets added to a list and they say they will...
