In the case of Paraburdoo with terrain around, an RNP-AR would be worthwhile and potentially knock a couple of hundred feet off the LNAV/VNAV minima. But a busted arse 30 year old Fokker can’t do them anyway so it’s not really relevant to this discussion.
The root cause was not the approach availability in PBO it was the lack of planning and inability to make a decision when backed into a corner. 60mins holding to then miss out and not have divert fuel is unacceptable. KTA, SLJ, GBW, ZNE all CAVOK and 15-20 mins away, even in an old bucket of bolts Fokker.
