Perth ammature drama groups

Hi there, Ive recently decided its about time I stopped wishing I was an actor, and tried to become one. But I really have no clue if I can act or not. Im pretty confident I am alright, but I suppose a lot of people think that. I've been trying to no avail to find a local ammature drama group SOR in perth. I am 21 so I'm looking for a mature age group. At the moment I'm not looking for a performing group, or at least not to perform myself. But just to find some like minded people to share my passion with. I plan on attending an 8 week workshop in feb through frog management so if I could get some experience before then it would be great ! Any info or advice would be awesome !
