Diagnostic delay is a major concern for children and young people with autism and attention deficit hyperactivity disorder (ADHD)—and also for their loved ones.

The delay is the gap between first concerns about a child's development, and their eventual diagnosis. In some cases this can be more than five years.

The scheme was overwhelmed by autism cases with nowhere else to go. Creating new services for them is one of the pointiest issues in the review.

One in five children in Australia have disability or developmental concerns, according to the Australian Early Development Census.

Federal and state governments may have to find $3.7 billion a year to support people with mild autism and less severe disabilities outside the NDIS, but Disability Minister Bill Shorten says he is confident his overhaul of the scheme will save taxpayers money.

The states and the Commonwealth will tip in $10 billion between them to establish a new scheme to treat children with mild autism and early developmental disorders, after the review into the NDIS said it must be reserved for those with significant and permanent disabilities.

The proportion of young children (age 0 to 6 years) diagnosed with autism in the NDIS has declined significantly since the full roll-out of the NDIS. The following chart shows the proportion of children in the NDIS with different types of "primary disability" according to data published by the NDIS on their website.
