I've never had to look in a different country, but I'l make some calls and see what I can come up with! Could you post a city, or specific area to look? (Im guessing that I will be asked this.)
In the meantime, please look up the book "The Bipolar Child" and get yourself a copy. This is the parents bible to bipolar children. (and dont get worried when it sounds like they have hidden cameras in your home lol; the book is THAT good.)
I will attempt to find someone with information on Australia's mental health community in the morning.
