Catholic experts have told an Australian government commission that the Church needed to re-examine its culture of clericalism if it wanted to help put an end to clergy sexual abuse.

Several experts also told the Royal Commission into Institutional Responses to Child Sexual Abuse that the Church needed the commission's help to get on the right track.

During a series of testimonies yesterday, Dr Michelle Mulvihill, psychologist and former Sister of Mercy who has worked with religious orders said: "The mismanagement of the Church is the business of the Royal Commission, in my view, because it has led to the situation that this Church is in. If this was a business, we'd be shut down a long time ago."
