This is the way I was taught to do it:
Taxi Call: "Bankstown Ground, ABC Cessna, Received Charlie, Taxiing VFR for 'Destination' via 'departure point', runway 11L."
Run-up Bay: "ABC Request Airways Clearance"
Yep. The reason I put a request in the initial call was because a VFR aircraft doesn't have to call Ground at all at BK. Asking for a clearance tells Ground why you are calling. You will probably get a transponder code initially. You won't get the actual clearance until you are ready to roll in the runup bay.
We have ATCers on PPrune. What do they say?
