The good thing about RAA and CTA (if you can call it a good thing) is that the regs haven't changed from day dot... you still need an approved / certified factory built aircraft and a PPL to enter CTA under raaus, or in the GA exp world you can do it with an amateur built with PPL.
Those that want to do this, generally, go and get themselves a PPL and the right aircraft and away they go into CTA. CASA have been great and made it even easier and introduced the RPL which is a piece of piss to obtain.
However... I don't think it's a gen Y thing, but there seems to be an ever increasing number of RAA pilots wanting to enter CTA. A heightened sense of entitlement? ... but I don't know why.
There's process and procedures for entry so people need to learn them!!!
