OK! Rather than just going around in circles, why don't we put up what we think the correct call shoule be! I'll go first, anyone else feel free to add/correct/subtract etc, then once we have got a consensus on each call, start another, might be a useful learning tool for those who wish to learn.
"ML Centre, Hughes 421 departed the Black Stump 47, tracking 123, climbing to FL230, estimating GRMPY at 13" and as we are proceeding into controlled airspace suffix this with
"REQUEST CLEARANCE". 
Refs: AIP GEN 5.14.8 (paragraph 4) and GEN 5.10 (paragraph 1).
Anyone else care to add?
