Don't worry, the federal Coalition's dream of moving a lot of Australia's population north of the Tropic of Capricorn ain't gonna happen. It's a crazy idea practically, politically and economically.

Presumably, it's a kite Tony Abbott is allowing to fly for a day or two to show how positive he is in his vision of our future. It's an idea some in the National Party would dearly love, but most in the Liberal Party will be appalled by.

The idea is to use tax and other incentives to entice Australians to live in places they don't want to live and do things they don't want to do.
