Dick is correct. This latest proposal from CASA is encouraging frequency separation which is what the MULTICOM is designed to overcome. It will have to be amended yet again as this and other aspects of the latest proposal are just unacceptable and besides it wont work.
And, CASA, can you please understand that "CTAF" is a set of recommended procedures, not a volume of airspace, it is NOT a poor man's "control zone" for "do-it-yourself" ATC.
CASA seem not to understand this.
