Thanks for the link.
The guy I spoke to who trained this way said he went to the ATO and after a lengthy explanation of the difference between RA and GA got the approval to claim back his further training as tax deductions, and did so. Grain of salt, of course, but he seemed to have too much information on this topic to be making it up.
I don't want to give the impression that I'm only interested in this pathway because of the potential tax breaks, though. Genuinely curious if people think this would make me a safer and more knowledgeable pilot that doing a more conventional order of licenses and ratings.
