Any friendly aussie who can help me on this matter?

Hi everyone!

Where in Australia do I turn to get a complete list of late actress Gerda Nicolson's work in theatre???

I'm from Sweden and happen to be a huge fan of Gerda Nicolson. I know quite a lot about her work on films and television (Prisoner, Bellbird, Bluey, Bankok Hilton), but I don't know ANYTHING about her work in Australian theatre and the theatre productions she's been part of...

Is theatre archive or something...? Or where else can you turn to in order to get info this kind of info? Do I turn to a library?

I have tried to search the internet and Australian search engines but with no luck so far...

I'm writing here since I don't know where to turn, but you have to begin somewhere...

So, if anyone can help me, drop me an e-mail, I'd appreciate it!

Thanks for you time!!

Yours sincerely,
Nina Lundstedt, Sweden
