If there is one class of person I have never quite trusted, it is a man who knows no doubt.

Both my parents loved words. That was the big deal in our house.

And at this moment in history, our core value happens to be the raw, aching truth of the human predicament. It may also be the only belief that can save us as a species. A species that will continue to find comfort and delight in the companionship of animals, the miracle of birds, the colours of the corals and the majesty of the forests. We are in it together, on this blue spinning marble in the cold and silent void. And we must act on that belief, if we are going to be able to continue to live a good life here, in this beautiful and fragile country, on this lovely planet, our only home.

What's wrong with leading the way? We've played that role before, after all. We gave the world the secret ballot... that did so much to raise living standards and improve conditions for workers worldwide. We were a leader in extending to women the right to vote. We were barely a nation when we set the bar for bravery and sacrifice by common soldiers in foreign wars. We grew up out of racism and misogyny and homophobia to become a mostly tolerant, successful multicultural society. We did these great things because we know we are in it together. It is our core value as Australians.

Writing is like bricklaying; you put down one word after another. Sometimes the wall goes up straight and true and sometimes it doesn't and you have to push it down and start again, but you don't stop; it's your trade.

We are not the only animal that mourns; apes do, and elephants, and dogs. Yet we are the only one that tortures.

Instead of idleness, vanity, or an intellect formed by the spoon-feeding of others, my girls have acquired energy, industry, and independence.
