$2200k ADHD evaluation in Australia, is there a way around this?

I was diagnosed with ADHD as a child and used to be on adderallxr. It helped me so much and I felt “normal” I ended up coming off of it when I moved to another state and went without it for sometime. But 3 months ago, I made a big move to Australia from the US and it is as if all my symptoms got significantly worse. So much so, that I scheduled an appointment with a GP to discuss options. They suggested a psychiatrist who could do a ADHD evaluation. After reaching out, I learned it was $2200k to be evaluated. Is this standard?
