Australian revisionist historian Gerald Fredrick Toben faces a hearing in London to determine whether he will be extradited to Germany to face allegations of Holocaust denial.

Toben taught at Goroke Consolidated School for two years until February 1985 and drove a Goroke school bus for four years.

Toben, a director of right wing think-tank Adelaide Institute, primarily a website, has consistently challenged history's account of the Jewish Holocaust during the Second World War.

Toben, 64, was arrested on a plane at Heathrow Airport on Wednesday.

Metropolitan Police executed a European Union arrest warrant issued by German authorities on a Dubai-bound plane.

The arrest warrant accuses Toben of having published material on the internet `of an anti-Semitic and-or revisionist nature' in Australia, Germany and other countries.

Appearing before City of Westminster Magistrate's Court on Wednesday, Toben said he did not agree to being extradited.

Toben told the court he did not believe he would receive a fair trial in Germany.

"It's a witch trial mentality in Germany concerning this matter, which is not the case in England yet," Toben said.

"I see this matter as a legal ambush."

A district judge denied bail and remanded Toben in custody to reappear for an extradition hearing today.

Toben was born in Jade, North Germany and migrated to Australia with his parents, twin brother and two sisters in 1954. The family bought a farm near Edenhope..

Toben completed a matriculation certificate with honours at Edenhope High School in 1962. Twenty years later he joined the teaching staff at Goroke school.

Toben was working at the ministry's Horsham office when it sacked him on February 4, 1985 for claims of incompetence and disobedience.

Earlier the ministry had removed him from his job teaching English at Goroke school.
