A high-profile Australian psychologist has been extradited from Queensland to New South Wales to face charges of historical sex offences against young boys while he was a scout leader.

The psychologist, who once treated contestants on a reality television show and profiled notorious criminals, faced Southport Magistrates court on Wednesday.

The 75-year-old, who cannot be named, was extradited to appear in Tweed Heads Local Court on Thursday to face charges dating back to the 1960s including indecent assault and buggery against three 12-year-old boys.
