The tailored (private) RNP at Gold Coast has worked fine for years..
Min is higher due to obstacles in the missed...and WAY too much emphasis has been placed on 250 vs 350 HAT of ILS vs RNP.
EDIT: Looking at the public RNP, and the other procedures, I think perhap reviewing the obstacles in the flightpath to get the min down would be much more cost effective.
