Oh and as to RAAF involvement -
the squadrons were involved but no one above the base CO at Pearce were consulted. The changes that ROTAP brought about involved the DCAF and the GM ATS being involved in the discussions. I am not aware of any such high level involvement in WARRP.
Perhaps this is why ROTAP gained so much RAAF airspace and WARRP got nothing but a few miles to the south. Remember that the SIDs and STARs were designed on the premise that RAAF were H24 and as such had to be convoluted H24 also.
