Our future growth relies on competitiveness and innovation, skills and productivity... and these in turn rely on the education of our people.

So in many ways for me, having lived through what I've lived through, and endured what I've endured, I've got more confidence that I can do the next bit - and there's something sustaining about that.

Over the Christmas period, I spent time with both Bob Hawke and Paul Keating, and you listen to stories and tales of how hard it can be when it's really hard, and I think we easily all talk ourselves into the proposition that it's never been as hard as this. Well it's been hard in the past. It's been really hard. So you keep doing it and, the more you do it, the more you gain strength and confidence that you can do it.

In Australia, average temperatures have risen almost one degree since 1910, and each decade since the 1940s has been warmer than the one before. That warming is real. Its consequences are real. And it will change our lives in real and practical ways.

Those of you who have spent time with Australians know that we are not given to overstatement. By nature we are laconic speakers and by conviction we are realistic thinkers.

Australians can trust me to get the job done. They can have the confidence that in the heart of the circumstances I will win through in their interests no matter how relentlessly negative the leader of the opposition is.
