An ILS on 34 would be great as would CATIIIB approaches at all capital cities. The obvious question is who would pay for it. The airlines won't as they don't think the small number of days it would be used is worth the expense. The gummint won't as they would consider that its not a vital piece of national infrastructure. Airservices won't as they would consider that the airlines should pay. Who's left? Would pilots put their hands in their pockets and pay for it?
So it comes back to playing with the cards you are dealt. If you fly in Oz, for better or for worse, you have to know how to deal with an NPA.
The worst way to deal with an NPA is to set the minima and push FLCH or OPEN DESC depending on your chariots manufacturer. This is fundamental stuff and not nice to know when you do your training. Thai Airways and any other airline who have pilots who don't understand the functions of these "buttons" need to look at their syllabus of training.
