Would introducing "legal plurism" of a non-extremist form of Sharia law encourage Muslims to move to Australia?

All laws are made based on a standard of truth. The Bible and the Koran are diametrically opposed and so any country that brings in Sharia law must remove Biblical law in the same proportion. The two cannot mix. Australia would be a fool to change what works for Sharia law. Look around at the countries that have it and notice that they are not as free as Australia. That would cease. Muslims do not think the way Australians do and that would pollute that country with another way of living. It is not just cultural, but what is truth.
