Australia's Jewish and Islamic communities have united to urge the country's immigration minister to deny a visa to British National Party leader Nick Griffin.

Griffin, who has a 1998 conviction for incitement to racial hatred for material denying the Holocaust, plans to visit Sydney and Melbourne in December.

Robert Goot, president of the Executive Council of Australian Jewry, said he had written to Immigration Minister Chris Evans, arguing that there is a "significant risk" that Griffin will vilify Australians or "incite discord" in the Australian community. The Federation of Islamic Councils confirmed this week it was in the process of drafting a similar letter.

Meanwhile, convicted Shoah denier Frederick Toben has won his fight against extradition to Germany from Britain for publishing online material "of an antisemitic and/or revisionist nature". Austrialia-based Toben was arrested in October on a European warrant executed on behalf of the German government after he landed in Britain while en route to Dubai.

Holocaust denial is a crime in Germany but not in Britain. Germany sought the extradition for material that appeared on Toben's website, even though it was based in and emanated from Australia.
