2. The current Naverus rnp approaches for Qantas have a roll out point at 2 mm from threshold, with rd turn before it. The icao ones coming later in the yr will be same.
Careful on this one. The FAF is at the beginning of the turn, not the end. There are many combinations of ac/fms types that will not allow a turn inside the FAF.

Bringing in the FAF close has its own issues as well. While some FMS models will taper the ROC, others will hard lock the 500' ROC at the FAF.
This is why on some approaches with the A320, the HW ac does fine, (HW uses 400' ROC at the FAF), the Thales box will prox warn....

Lots of flight vals with different equippage must be done for the ICAO procedures.
