Oh OK... I'll bite.
I have been a Chief Flying instructor for both types of school. I can only comment on costs, I won't comment on Melbourne schools because I have no idea about them.
The simple answer is that RAAus is cheaper
in the short term. If you have serious cash restrictions at the moment and RAAus gets you into the air, go for it!
If you really want to fly bigger aircraft, in
my observation a RAAus pilot will spend significantly longer learning the additional systems and complexity of a GA aircraft to the same level of competence they previously demonstrated in an RAAus aircraft.
Edited to note: most of my RAAus studes and RAAus -> GA conversions have been older blokes. Younger people can learn almost anything much more quickly and so the differences are less.
This means that the cost benefits of going RAAus early
might be evened out by the time you qualify with a PPL.
There are all sorts of arguments that RAAus is a lower standard or lax with rules - if you pick a good professional school and apply yourself to your studies you will become a competent pilot within your chosen branch of study.
Apply the same principles and effort and you will match it in the other discipline when the time (or cash) comes for you.
Good luck and have fun
