I don't blame CASA at all.
I blame the former Minister for Transport for creating rules that require airports like Dubbo and Bathurst to have the same sort of security as Kingsford Smith, then creating an unworkable system that requires part time pilots to carry a separate id card for every airport they fly into, without any guidance as to how to go about it.
I also blame the new Minister for Transport for taking one look at the sorry mess and making a quick flick pass out to CASA at the 11th hour, to implement the system they clearly aren't resourced for, so that when the whole thing collapses he can say;
<Krusty the Klown>Don't blame me. I didn't do it!</Krusty the Klown>
Meanwhile, after having all the time, energy, effort and expense of passing my licence test, I have now been waiting 6 weeks plus for a piece of paper which used to be issued on the same day.
