NO, NO, HELL NO.
Ask three CASA FOIs the same question and you get three different answers. Lack of training, lack of standardisation. Not their fault.
Deal with head office CASA in Canberra, then one of their capital city offices; you get two different demands for the same application or approval. Very much their fault.
Among the FOIs there are a few good people in CASA, but sadly they are stymied by overall organisational dysfunction. Team Leaders (or whatever they call them these days) live in their own silos and, like politicians, are all about covering their own sad arses.
USELESS.
