Disability advocates say revelations of a cage built for an autistic child at a Canberra school are just the tip of the iceberg.

The Principal of the school, which cannot be named due to privacy reasons, has been stood down as an investigation is launched.

The cage at the Canberra school was exposed following a complaint to the Australian Human Rights Commission.

Images obtained by SBS show what some schools use as so-called withdrawal areas for autistic children.

In the wake of revelations an autistic Canberra student was confined in a cage-like structure, former disability discrimination commissioner Graeme Innes says such abuses are widespread and has called for a broad inquiry into the treatment of children with disabilities in the nation's schools.

Opposition Leader Bill Shorten immediately backed Mr Innes' call, declaring: "we cannot assume this is a one off case".

Mr Innes, who served as the nation's disability discrimination commissioner from 2005 until last year, said such "appalling" incidents were not confined to the ACT.

News of a cage-like structure being used to constrain a Canberra school child has come as no surprise to some parents, who say their children have also been poorly treated by the system.

The ACT government has confirmed the cage structure built to contain an autistic Canberra school student had a roof, as shock and distress at the behaviour control technique spread nationwide.

Canberra Raiders coach Ricky Stuart - a prominent autism awareness advocate - joined a chorus of disbelief after Thursday's revelation a primary school had used a 2m by 2m structure made of pool fencing as a "withdrawal space" for a 10-year-old boy.

It's a horror you might read about happening in some awful foreign town. But it happened here, in Australia. In NSW.

A school that placed a child with special needs and behavioural issues in a cage-like withdrawal space told parents it had intended it to be a "sanctuary". 

ACT Education has suspended a principal and launched an investigation into how a primary school student was placed in the purpose built two-by-two-metres structure made of metal pool fencing.

Autism experts have lamented reports a 10-year-old boy was placed in a cage at a Canberra primary school, saying it signals a national standard for autism education in mainstream schools is urgently required.

ACT Education Minister Joy Burch confirmed the unacceptable "withdrawal space" had been built in a classroom to deal with a student with challenging behaviour.
