The aged care complaints commissioner is reviewing the case of a bedridden 89-year-old man who was abused by his nursing home carer.
Video from a secret camera shown on ABC's 7.30 program on Monday appears to show a carer violently force-feeding Clarence Hausler, sneezing on him, pinning his arms down, flicking his nose and holding a large napkin over his face.
Daughter Noleen Hausler installed the hidden camera in her father's room after she became suspicious about her father's bruises in 2015.
She later took the video to police and the carer was convicted of two charges of aggravated assault, the ABC reports.
The aged care facility in question, Mitcham Residential Care Facility in Adelaide, said it didn't tolerate such behaviour.
"This conduct is not tolerated by our organisation and is completely at odds with the care, dedication and commitment displayed by the over 4500 nurses, carers and other staff across our homes every day," the facility said in a statement to the ABC.
