The NDIS responded to A4's FoI request (20/12/2019). The two document can be downloaded from the links below.
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/1588 and http://a4.org.au/node/1654. The NDIA omits this correspondence from its FoI documents below.
The follow up correspondence expresses disappointment that the NDIA did not address the issues raised. No progress was made.
Apparently, the NDIA had the document Evidence for Effectiveness of ABA as a Treatment for Autism in its possession but there is no information to show that it advised its planners of its content.
