Not everybody who gets a CPL wants to go Airline flying, there's a more interesting/rewarding career if your not after the bars, hat and being called Captain.
I'm not sure that really hold true anymore. Everyone I have ever worked with who tried that is no longer flying professionally or moved into an airline. Ultimately there are few career flying opportunities outside of airlines in Australia. Sure you can travel the world continually chasing GA jobs, but ultimately that gets tiring or you get married and the wife just wants to settle down. I don't think that the whole FIFO pilot gig to some third world country is all that appealing over a long period of time either. Most domestic airlines or regionals have you home enough to make it pretty enticing to most people, assuming you can make the grade.
Ultimately though the cost of training is going to have to go down if they expect anyone with half a brain to become a pilot these days.
