Muslims are being urged to stay away from the Sydney Royal Easter Show by a community group linked to Islamist fundamentalists.
Sydney Islamic Lectures posted a "must share ASAP" message on Facebook as thousands of people flocked to Homebush in the city's west for the opening day of the annual showcase of agricultural produce, according to Daily Mail.
"The Easter Show is on again this starting week. Many Muslims are attending without knowledge," it said.
The group, which posts links to Islamist groups and sharia law lectures, shared a YouTube video of fundamentalist Sheikh Feiz Muhammad.
He gives weekly fiery sermons at Auburn, which is a few suburbs away from Homebush, where about 850,000 people are expected to attend the Easter Show during the next 13 days from Thursday.
