The Federal Government will unveil a draft terms-of-reference today regarding the Royal Commission into the mistreatment of disabled Australians.

The public will then have two weeks to give feedback on the scope before it is finalised.

The proposed terms of reference have encompassed a wide range of contexts, with Social Services Minister Paul Fletcher stating that the draft is deliberately broad to ensure no one falls through the cracks.

Disability Advocacy Network Australia chief executive Mary Mallett said, "it looks to me as if they have pretty well covered off the areas people are concerned about."
