That’s a very good and valid point, KRviator.
I’d be happy to pay twice the amount I’m charged each year (legitimately or otherwise) so as to avoid the AvData correspondence bureaucratic distraction, entirely.
The good news is that, like the regulatory reform program that’s going to make things simple and cheap, the GST is going to replace all the ad hoc and inefficient charges. In other words, GA in Australia is completely f*cked.
