Perorming arts courses can you add any

I think that's all there is in the way of degree courses in Oz

VCA (University of Melbourne) has a one year foundation course in music theatre

NIDA (University of NSW) has a one year part time music theatre course called Singer Dancer Actor

If you are more of a dancer Brent Street does a performing arts certificate (one year) their graduates tend to do quite well in the industry and brent street hold auditions in Perth (bonus!).

ACTT
Also have a one year course focussing on the acting side of mus theatre
www.actt.edu.au

There is also La Salle college of the arts in Singapore which does a degree course in music theatre. That one is quite new.
All these courses are quite exe though!
I would be wary of Stage Door.

Hope that helps chook!
Good Luck
