Australia got it right back in '05

hopefully they've stayed that course, but they were well ahead of the curve obviously.
there are some clerics who have been quoted as saying they recognise two laws. They recognise Australian law and Sharia law. There's only one law in Australia, it's the Australian law. For those coming to Australia, I think we ought to be very clear about that. We expect them to recognise only one law and to observe it.
Now, for those who are born in Australia, I'd make the same point. This is a country which has a Constitution. Under its Constitution, the state is secular. Under its constitution, the law is made by the parliament. Under its Constitution, it's enforced by the judiciary. These are Australian values and they're not going to change and we would expect people, when they come to Australia or if they are born in Australia, to respect those values.
I know there's some confusion as to which Aussie leader made the speech that is commonly associated with this, or even if such a speech was made at all. I trust snopes to a far degree, but even if on the smallest off chance they got this one wrong, I think every western country, and their governments, need to take note. Because the overall premise is 100% correct in my view.
