Dick,
I think you mixed me up with someone else, but that's not important.
Okay, let's look at Ballina...
Class G
RPT calls taxying and gets traffic information from ATC ... on IFRs. He gets the VFR picture from the CTAF. Once he departs, he continues to get Traffic Information until he gets his clearance.
Class E
RPT calls taxying and, if he is IFR (which all RPTs will be .. at the moment) he will get a clearance and , I guess, has to look out for VFRs ... not required to call. If he could change to VFR, he would get nothing.
And, from what ARFOR provided, Terminal Class E is not permitted in Australia.. so it's a moot point anyway.
