He definitely made mention of the unions as that stuck in my mind.
On the two flights I did (up and back), the PA seems to be quite a variation to the script. Both were considerably different and they way they were spoken, it would appear they were being thought of as they were speaking, with some of the script thrown in, as I recognised some of the wording. It came across long-winded and a little tardy.
Just for note - any QF380 drivers out there; check your mic's. On the four 380 flights I have done, the flight decks PA's have been deafening. Extremely loud. Especially with headphones on. CSM PA's were fine.
