I'm a big fan of clarity, so my new hero is Peter Costello, the treasurer of Australia:

If you are somebody who wants to live in an Islamic state governed by sharia law you are not going to be happy in Australia, because Australia is not an Islamic state, will never be an Islamic state and will never be governed by sharia law.

We are a secular state under our constitution, our law is made by parliament elected in democratic elections.

We do not derive our laws from religious instruction.

There are Islamic states around the world that practise sharia law and if that’s your object you may well be much more at home in such a country than trying to turn Australia into one of those countries, because it’s not going to happen.

Via Tim Blair, who suggests that Costello's words "be displayed in the arrivals areas of Australian airports."
