The most frustrating thing for me is the recommendations by the ATSB over the RNAV GNSS approach chart design and presentation issues. CASA has done very little with these recommendations apart from now depicting significant topographic terrain on these charts (which has always been an ICAO requirement which they chose to ignore mind you)
We are still left with a unique method of waypoint coding that is not used anywhere else in the world which can be clearly linked to SA issues. You just have to ask why does CASA keep its head in the sand?
