What I don't get is the exemption for Private IFR flights, which is restricted to class G, E, and class C providing you are flying to a class D airfield. Why aren't you allowed to fly into class C CTR? For example, I can fly through class C into Parafield (class D) but I can't land at Adelaide (class C CTR) but Adelaide doesn't have an ADS-B receiver (as of June 2016)!!! So if I had ADS-B I can fly into Adelaide, but it wouldn't make any difference as they can only use radar and SSR. If I do not have ADS-B then I can't fly into Adelaide despite the fact that they are only going to use radar and SSR! Casa Instrument number CASA 114/16 has got to be one of the most useless pieces of mindless bureaucratic rubbish ever!!!
