The mother congregation of Australia's Jewish community has closed its doors to a visiting extremist Israeli politician who has publicly condemned homosexuals and dubbed Palestinians "bandits".

The newly-minted chief minister and rabbi of The Great Synagogue in Sydney, Benjamin Elton, said Moshe Feiglin was not welcome.

"He wouldn't be welcome here," Dr Elton said.

"I'm absolutely opposed to any sexism, racism or homophobia."
