Disability advocates say mainstream schools are unable to meet the needs of autistic children, and as a result families with autistic children are being forced to homeschool their children.
Many parents have told a Senate inquiry that their autistic children are bullied, misunderstood or placed in cages or seclusion areas in mainstream schools.
Sydney mother Cassandra Winter homeschools her son, who has autism and is currently in grade two.
She said the two schools he was previously attending lacked specialised support.
