A 74-year-old man has been extradited from the ACT to Tasmania to face historical child sexual abuse charges.

The allegations follow a “complex and protracted” investigation stemming from the Royal Commission into Institutional Responses to Child Sexual Abuse.

The man is accused of repeatedly sexually abusing a child and is expected to appear on Thursday night in Hobart Magistrates Court, Tasmania Police said in a statement.

The charges relate to crimes allegedly committed in the 1980s when he was living in Tasmania.
