So what part of what I have said is " complete nonsense" ?
And yes. Monitoring the CTAF if in the approach or departure area of an airport is stock standard Australian NAS policy.
Prior to the 1991 AMATS changes all VFR above 5000' in G gave mandatory full position reports as IFR and VFR flew at the same levels. Both IFR and VFR could not even communicate to a radar controller even when in radar airspace. That's why I made the changes.
