Yes, I know G without a transponder requirement is OK at places like Broome and Ballina - but upgrade the airspace to E and add a mandatory transponder requirement and it suddenly becomes unsafe.
Get Real!
Ok ...lets get real!
With respect to Broome at the moment yes it is Class G, and due to traffic density etc it has been declared in need of a Class D tower, so yes at the moment it is deemed NOT SAFE ENOUGH.
With Ballina it is clearly not reaching that level of Traffic, however if you wish to push the barrow for increased level of surveillence at many aerodromes (I recall an ADSB debate some time back) Class E to the ground would be welcome I am sure, and only then increased to D or C as the need arises.
E without radar/multilat/adsb is a waste of time.
If I get it.....why is it your friends do not get it.
