Young Melbourne actress

Hello, I'm 13 and i have been training for a acting career since i can remember. I've done my 3rd grade AMEB singing exam and 2nd grade AMEB clarinet exam. I also learn the flute. I've had speaking role in our secondary school musical. I have also done my 1st grade AMEB drama exam. I've also modeled for Bettina management in the past. I have begun acting for camera classes with NIDA and have done Brave studios acting for camera holiday program.I live in Melbourne and i am interested in joining Catherine poulton management. Is this enough to stand a chance in CPM's fierce competition? Anyone with experience please help. Also where can i go to get more EXPERIENCE? Thanks
