Andrew Meadows, 56, told the commission he was sexually abused by his father from the age of 5 before being sent to another home.
The commission is holding public hearings focusing on state run residential homes and family foster homes.
The inquiry heard Meadows was abused by Nigel Hibberd who, with his wife, ran a family home in Henderson.
He complained to the then Social Welfare Department and later found out he was not the first.
"Why the hell did social welfare place me under his care knowing that there was already complaints. When I found out later on, I was absolutely gobsmacked."
