I am a child and adolescent psychiatrist and agree with odette- that if you are concerned then get an assessment of some sort. It may be within the "normal' range but it you are concerned enough to ask the question. In terms of where to go, I am in SA and do not know a lot about Qld health system but other options (odette has already suggested some good ones) would be talking to your child and youth health service, child and adolescent mental health service or Autism association (not sure if every state has one). We have Autism SA and despite the name it actually cover the spectrum of disorders including aspergers. Good Luck with navigating it all.
