This query is with respect to a Private Pilot who will never go into capital city port of entry airport.
I've read the CASA website detailing the differences and its not totally clear to a dummy like me. Mention is made of "secure areas" at security controlled airports. But no mention how such areas are defined. (

So on to the question of practical use, is any private pilot successfully using an AVID just for infrequently going through places like Roma, Thargomindah, etc. i.e security controlled airports with domestic RPT service.
What about regional port of entry airports?
