Unfortunately, Dystonia Australia had to close last year due to lack of funds. I had only just found them, so i was pretty dissapointed when they had to close.I wouldn't recommend any of the pediatric neurologists that i saw as a child. I wasn't correctly diagnosed until i left the children's hospital system and saw an adult neurologist (even though my dystonia (DRD) is a childhood onset condition).
I have a friend with dystonia who lives in Queensland, i will e-mail her to see if she has any ideas for you.
Take care,
Vettey
