Why would we be surprised kharon, anyone who joins CAsA is automatically anointed as "Expert".
Look through a few AAT proceedings.
Real experts, with real qualifications and real experience from industry, are largely ignored, in favour of CAsA experts made up of people who couldn't be employed by industry because they require competent people, or RAAF failures who's progression in the RAAF had stalled because they also needed competent people.
Same same the way they selectively massage statistics to promote the Myth that Australian aviation, because of CAsA oversight, is the safest in the world.
