Leadsled,
That may well be so, however, since we are talking about Aus airspace with mainly Aus pilots who normally, guess 99.9%, don't have access to the documents you refer and do use AIP and Jeps for as a reference, it would be reasonable for them/us to know the content of those docs.
Back to the original topic, if standard phraseology was the norm, in my oppinion, it would make life a lot easier for not only pilots with english as a second language, but ATC and the rest of us.
