Perhaps he should, (and a simpler way is to go to the CASA regional office and look at a Form 196 - application for ATPL(A)) but that is not my main point.
My main point is that it doesn't matter what we think about the rules. They are there. Sure, there is some regulatory reviews and new FAA style stuff on its way, but a re-write of minimum experience requirements for RPT PIC is WAY down the CASA to-do list.
If a non-instrument rated pilot knocks on the door of a night freight operation, he/she can expect to be told to parse off and do a CIR and don't bother coming back until you have it.
So if it is your intention to get a job working in an airline type operation sometime within the next 5 years or so, don't expect to get anywhere until you have the minimum requirements for PIC RPT.
Once you have those minimums, then go and fly PC-12's, Boeing Tiltrotors, ground effect vehicles or whatever interesting and challenging equipment you may find until Qantas/
VB/etc start interviewing, if that is what you want.
