A few pilots including myself got messed around a lot at Bankstown airport not long ago doing a CIR. The experienced instructors have either gone to the airlines, given up or simply aren't interested any more.
I know of a few other pilots that went to Johnston Aviation (at Port Macquarie) to do their CIR & were very satisfied. From what I heard I wish I had gone there myself. The trip out of Sydney would have saved me a few headaches as well as $$.
