Australians living in disability group homes have been involved in more than 7000 reportable incidents in the past four years but advocates say that might just be "the tip of the iceberg".
A report by the National Disability Insurance Scheme Quality and Safeguards Commission examined the seven largest accommodation providers and found more than 1700 of those incidents involved a serious injury to a participant.
The startling figures are another problem for the NDIS, given fewer than 20,000 Australians live in disability group homes.
