Yeah I think it is time that CASA AND the airlines had a look at this whole Single Engine Turbine Issue. It is stupid that you can have several thousand hours on a PC-12 flying higher than all regional turboprops and just as fast as some of them but when it comes to to hiring they want you to buzz around in a piston twin for 500 hours. It a ridiculous situation that really just shows how backward aviation is. PC-12 is as advanced as most and in some cases (ie metro 3) more advanced than regaional airliners. In the states regionals will wavier twin time for ASPETA exerperience under certain conditions (ie it can't be private. has to be either LCRPT or some under some other reg they've got)
So maybe it's time that CASA moved with the times and changed the regs to suit the change in technology. If they are quite happy for a cadet with a 100 hours PIC to eventually become a captain on a heavy jet then surely to goodness that a PC-12 or Caravan pilot can move onto something bigger without having to burn around in a clapped out twin just so he can tick a box!!!
