nice time to completely withdraw an ILS (Right in the middle of the wet season).
Is there a good time to take out an ILS? Last September in Cairns they decided to replace the ILS in what should be a good weather month. Well from memory it rained for 1-2 weeks and every man and his dog was diverting.
I do feel for you in regards to your other points. Unfortunately I believe the poorer infrastructure is a part of flying in PNG.
