local theatre groups/repertory clubs Perth area

I am looking to join a local theatre group or repertory club, you know the like, basically to become involved in/audition for productions. Note i am not interested in musical theatre - straight acting only, i was a member of the Bunbury Repertory Club and involved in several performances at the little theatre if anyone can recommend a similar group in Perth, preferrably south of the river, but not essential would be much appreciated!
