oops .. in the 3rd paragraph of the article in the post this replies to a referendum is mentioned .. i'm repeating the link and the first three here for easy context ..
"Frontbencher Ed Husic's swearing-in on the Koran was celebrated by some, yet was the source of vitriol from others.
A common theme in many of the negative reactions was Husic had breached something fundamental in Australia's system of government. One person commented: ''How dare you disregard Australia's constitution like that. Absolutely sickening. Do we begin the push for sharia law now?''
Such concern is surprisingly prevalent. An email with a wide circulation is urging a ''no'' vote in the referendum because, ''by local government areas being recognised, sharia law can then be demanded in the local area, based on the [percentage] of Muslim people in that local area''."
