Dick - you need to forget ifr v vfr in C and think of ifr v ifr in D which you've no doubt experienced in imc at Bankstown. It's pretty obvious from listening to the radio (and waiting) how procedural separation works - controller can't see you, you can't see the other guy, clearances reflect that.
Now, back to remote (or local) procedural C. Ifr v vfr - same concept - controller won't issue clearances to conflict traffic they can't see or can't separate itself. No problems - inefficient maybe - but safe.
In the Tobago v 737 story you're certain the vfr pilot was on top of his game and being a responsible airspace. Now suddenly the night VFR guy seems unable to know where he/she is and make a position report? You need to be consistent.
As was said earlier, these threads make it very possible CASA can reasonably ask you to reset exams based on your lack of understanding of the basics.
Like AOTW says - you've got a gig at a significant press conference tomorrow- please stick to the subject and not this embarrassing sideshow.
