There are more chinese, spanish, german etc cabin crew working out of Australian bases than I care to point a stick at.
Do a PVG or PEK and see how many Aussie sounding crew are on those.
Yes but they are Australian residents/citizens and live here permanently (apart from the odd long-distance commuter). We are very much a multicultural society and these people working for QF are simply a cross-section of that society.
It's not about being "aussie sounding".
What I was referring to with the Thai/LHR crew is completely different.
