Would love to get back into it!

Hi I have always had a love of the performing arts. I was heavilly involved with different productions at high school and held some lead roles. I spent a year in America and was involved in some of their amateur theatre groups over there and also have been involved a little over here but haven't done any in ages. I would love to get back into it! I've always felt like something is missing and just to be able to get back on the stage and perform again would fill the gap! Just wandering of any local theatre groups which I can become involved in or who are going to be doing a new productions soon perhaps audions could let me know please. This would be much appreciated. I don't have any professional training but am enthusiastic and passionate.
I'm in Perth WA. Look forward to hearing some response.

Cheers

Trish
