The number of Australian children diagnosed with Autism Spectrum Disorder may have skyrocketed but many will be "un-diagnosed" in adulthood.

Early diagnosis and programs are helping those with Asperger syndrome - now known as high functioning autism - deal with social deficits and other challenges.

"We are now getting people who become what we technically call sub-clinical," autism guru Dr Tony Attwood told AAP.

This means they've reached a "level of expression" that doesn't need specialist services or support.

Society needs to stop considering autism spectrum disorder as a deficit and start embracing difference, a South Australian expert in special education says.

Department of Education and Child Development special educator Kathy Kleinschmidt said autism spectrum disorder (ASD) was just that; a spectrum, and many ASD children were highly functioning — if just a little bit quirky.

Ms Kleinschmidt said high-functioning ASD children should be able to attend mainstream schools, but there needed to be education and tools available to staff.

The Australian Institute of Health and Welfare (AIHW) produced a brief report that summarises recent Government data on autistic people in Australia.

It says:

My then five-year-old son was diagnosed with autism spectrum disorder (ASD) around the time in 2007 the United Nations declared April 2 as World Autism Awareness Day (WAAD). He was on the cusp of school and I worried what the diagnosis meant for his future.

Increasing awareness of autism, the promise of the NDIS, and biological factors like older parents are driving the boom in diagnoses, according to experts.

The number of Australians diagnosed with autism increased by 42 per cent between 2012 and 2015, but research and advocacy groups are adamant it's not a cause for alarm.

Landmark decision comes as court rules transport to and from Victorian man’s disability support program is a ‘reasonable and necessary’ support

The national disability insurance scheme is required to fully fund any supports or services it has deemed “reasonable and necessary”, according to a landmark decision handed down in the federal court on Tuesday.

See http://a4.org.au/node/2059. It seems that the NDIS simply "lost" this matter. AEIOU told A4 they have no idea what this was about. The NDIS has not published anything we could find about this trial. A4 doubts that this trial ever existed.

Dear Mr Buckley

Please find attached correspondence acknowledging your request under the Freedom of Information Act 1982.

Dear the Hon Jane Prentice MP

We thank you and Mr Russell de Burgh for your response (MC17-003466 on 28/3/2017) to A4's email, and especially for specifically answering the questions we asked.

The webpage your response refers to, https://www.humanservices.gov.au/customer/services/centrelink/disability-support-pension, says (repeatedly) that people who are either "permanently blind" or " have a physical, intellectual or psychiatric condition" may be eligible for Disability Support Pension. We understand that people who to not satisfy this description are not eligible. This description of eligible people excludes most autistic people. Autism spectrum disorder (ASD) is not regarded as a "psychiatric condition" even though the diagnostic criteria are described in the DSM-5, a manual of mental disorders. Current estimates suggest under 50% of autistic people have "intellectual impairment". ASD is not physical impairment. The Australian Bureau of Statistics estimated that in 2012, 73% of autistic Australians have severe or profound disability (limitations on core activities), so it would seem that a high proportion of autistic adults should be eligible for DSP.
