I have a feeling it might work out a bit different to what "
Uncle Mick" has said. As is well known, CASA is busily engaged in rewriting the rules for harmonisation with ICAO and JAR. We're well into the same process but only looking at harmonisation with ICAO right now.
Anyway, in our new rules, "Aerial Work" will basically cease to exist. If it's a revenue operation, it's like Charter, so will get a similar AOC and demand similar levels of compliance. There's a suggestion that CASA may yet go down the same path.
I can see the combatants lining up already ...
