I guess I will provide my opinion in this one. With all due respect to excellent education that Australian conservatories provide, they simply cant be compared with the major conservatories in USA or Europe. Just compare the audition requirements and the selection procedure and you will get what I mean.
However, do note that there is this misconception that you have to get into a top conservatory such as Julliard or RCM etc or you have to be "super talented" to make it into performing. We are living in this very real world in which only the top few pianists ( e.g. Kissin ) can fully survive on performing alone. Ask yourself why do you learn piano ? Do you do it for the fame and glory ? Or do you do it for the love of music ? A lot of piano students that I meet seem to be deluded by this idea that they can make a living off a successful performing career. But even the most seasoned pianists will tell that performing line is very tough and a pianist should be as versatile as he/she can, and you DO NOT have to get into a top conservatory to be a successful musician, though it helps if you can.
Truth is , these top conservatories take in only the best of the best , who have the necessary talent and dedication to be notable musicians. I am currently in a local conservatory in my local city, sure the standard is much lower compared to say Juiliard, but I am assured that I will be properly equipped to start a decent music career, and if my ability allows, I will try for a more renowned conservatory. It is often wiser to take a smaller step at a time rather than a big step and stumble halfway. And it is often tempting to try to go beyond what our abilities realistically allow, because of the lure of the recognition and glamour. But I tell myself, hey, I'm not in Juiliard, it's not big deal, and perhaps, I couldn't even compare to the lousiest student in Juiliard, but I decide to make music my life and do my best wherever I am, all things will work out for you if you have the determination and abilities.
