A4 had some follow up correspondence with the NDIA about the NDIA's response to A4's email to the Ministers. That correspondence is available at http://a4.org.au/node/1588and http://a4.org.au/node/1654. The NDIA omits this correspondence from its FoI documents below.
A4 received this response (link to download and accompanying email below) to our DSS FoI request - see https://a4.org.au/node/2155.
Basically, DSS's response below says it has no record of anyone passing A4's letter to the Department (which should mean DSS, the NDIA is "the Agency"), as Assistant Minister Prentice's Office told A4 in an email on 4/12/2017. A Department representative suggested (on the telephone) that A4's letter was sent to the NDIA, not to the Department.
A4 is puzzled and disappointed that your Concluding Observations make no reference to autistic Australians. Excluding autistic Australians from your observations leaves them feeling that a crucial human rights body fails to recognise their needs and right.
