18 yr old seeks film experience

My name is Sophie Kesteven, I am 18 and have recently been offered a place in RGM's books. However I have done mostly theatre work and now need to move into film, to prove my worth! Unfortunately I have a long period away this year (11/7-14/10) but I am looking for anything, big or small, before and after this period. Also, I am located in Perth, so productions may have to be around the area. Can anyone help?
