The Federal Opposition says convicted terrorism supporter David Hicks should be forced to surrender the profits from his memoirs.

Mr Hicks has released a book about his time in the Guantanamo Bay prison.

Shadow Attorney-General George Brandis says it appears to be a clear breach of proceeds of crime laws.

"David Hicks, who admitted to a terrorist offence, is now seeking to profit from his crime and that should be prevented," he said.

"The appropriate application to the court ought to be made for the surrender of those profits."
