I’m sorry but you are wrong. Snakecharma is correct in what he/she says. Without permission from CASA or the ATC service responsible for the airspace in question, you can’t fly a model aircraft above 400ft in CTA or within 3nm (5.5km) of any aerodrome. Period.
8. MODEL AIRCRAFT OPERATING AREAS
8.1 Before flying above 400ft within controlled airspace or within 3 nautical miles of an aerodrome, the operator of a model aircraft must obtain permission from the appropriate air traffic control service or CASA as appropriate.
