If you try to come to Australia by boat, even if we think you are the best person in the world, even if you are a Nobel Prize winning genius, we will not let you in.

We are already experiencing the symptoms of climate change, especially with a hotter and drier climate in southern Australia - the rush to construct desalination plants is an expensive testament to that.

Nobody looks at opinion polls with more attention than politicians, but of course you've got to remember that a single poll is a snapshot in time.

There is nothing more important in business or politics than a deal is a deal.
