Simply, there are too many Australians training on the airbus, teaching how to grasp the non-essentials which does not help in command training!
The Aussies can go and do one. They try to come across as a bunch of geezers who couldn't give a fair dinkum, moaning about the 'system' but are the most anal people I've ever met. Yet their grasp of English extends to words like Awwwwww, naaaaaw and yeaaaah maaate. Not to mention going non-staaaandard on the cockpit temp turning it up full right.
