Why would the ATSB feel exposed? They just call it as they find it. One factor missed by a lot of people is that the Metro would have been required to have had EGPWS fitted a month later. While there are problems with the way GPS approach charts are presented the F/O did not have the experience or qualifications to perform his job properly. This is the type of CFIT accident that has similarities with many other accidents where the cockpit gradient was very steep. The F/O was put in the RHS with little or no training on what his role would be.
CASA cannot duck their responsibilties. They only acted when presented with information that they should have found out years before. Why did the Chief Pilot have approval to be in that position when he had so many other responsibilties? Why were any pilots flying RPT routes when they were not GPS endorsed?
I hope the Coronial picks up where the ATSB report finished.
