Profits from David Hicks' controversial book about his six years in Guantanamo Bay have been frozen as prosecutors pursue the Adelaide-born terrorism supporter under proceeds of crime laws.

NSW Supreme Court Justice Peter Garling issued a restraining order on Wednesday relating to Lakeside Pty Ltd and Misha family trust, which are linked to proceeds from Hicks' memoir.

The Commonwealth Director of Public Prosecutions (DPP) wants to seize profits from Guantanamo: My Journey, which sold about 30,000 copies and is believed to have generated about $10,000 for Hicks.

The memoir tells the tale of his incarceration in the controversial US-run jail between 2001 and 2007.

The court order came as politicians described the case as politically motivated.
