The [Maicolm] Turnbull government's position on this is perfectly clear. We believe that there should be a plebiscite so that all Australians can have their say, and that is what Australians want.

Capricornia is one of the most marginal seats in the country. So naturally the electoral battle is fought in the marginal seats.

One of the things about federal politics is that it has been remarkably free of corruption.

Malcolm Fraser, in the marrow of his bones, despised racism. He despised people who discriminated against other people because they were different and in particular because of the colour of their skin, and I don't think there has been a time in Australian politics where there has been more attention to the importance of that value.

I'd say about Malcolm Fraser, as he said about himself, is that he was always, from the day he entered Parliament in 1955 until the day he died today, was a Liberal.

A dining club which I was involved in at Oxford University invited Sir Isaiah Berlin to dinner, who I believe was probably the greatest liberal philosopher in the 20th century. I sat beside him and we spoke about liberal philosophy and the events of the 20th century all night over dinner - it was unforgettable!

We must break out of this mindset in Australia that we are a small nation on the other side of the world from the main, great Western nations. Australia is the twelfth largest economy in the world. We are a not insignificant player in commerce, in geopolitics and we must be in culture as well and we are.
