Hi Lad,
Not so sure if Oz have many places to hire a/c's for you to build 1,250hrs and if they do the prices would be insane. You may want to reconsider going to places like Canada or USA where availability of a/c's and AVgas is cheap. Case example after completing my studies in US my flying school allowed me to rent their C152 for $70 (wet) ph.
Just do alot of research and make sure you get the best value out of your investment. All the best lad.
