Starting in Perth

I'm 19 years old and I want someone to help me out finding a course or community theatre which runs acting classes, training or something. I have had very little experience prior to this. Back when I was 15 I did some high school production playing the lead and was going to acting classes at Actors Management on Kings Street in Perth (which it is now closed down). I was wondering if anyone had any beginner-intermediate suggestions of courses/workshops/ect for someone my age now? Thanks, Alex
